x ABSTRACT In Pakistan, Hystrix indica is abundant and distributed all over the country. It has been identified as a serious pest of traditional as well as non-traditional crops, trees and shrubs. The prospective porcupine belt of the Punjab has been divided into four ecological zones i.e., rainfed Pothowar belt; irrigated forest plantations and embankment of link canals, desert lands and agricultural lands. The fecal pellets and stomach contents of H. indica were collected from the randomly selected sites. An analysis of 131 stomachs contents and 480 fecal pellets revealed that 44 species of different plants were consumed by the porcupine as food. H. indica mainly likes to consume agricultural crops including vegetables and fruits rather xeric vegetation. It is analysed that the diet of the porcupine comprised of vegetable matter, roots, seeds, leaves, stems, spikes, tubers, flowers and pods. Maximum food diversity was found in irrigated forest plantations. The data collected on tree debarking in plantations revealed serious damage to different tree species. The incidence of damage to Eucalyptus camaldulensis, Dalbergia sissoo, Morus alba and Albizzia procera averaged 15.16±2.04, 15.18±1.79, 12.38±1.86 and 3.44±0.04% respectively. However, the degree of damage to different tree species among the plantations showed highly significant difference. Damage to mature tree of Acacia modesta, Populus deltoides and Tamarix aphylla was not recorded. On an average, plant nursery of Bombix ceiba, Dalbergia sissoo and Alibizzia procera received 58.4±4.00, 9.81±2.69 and 6.79±2.23% damage respectively. Up rooting stumps of Dalbergia sissoo, Bombix ceiba and Eucalyptus camaldulensis after transplanting is a characteristic behaviour of Indian crested porcupine that was commonly observed in the plantations or on farms visited. Necessary control measures are also suggested.

INTRODUCTION

Agriculture sector provides 44.65% employed labour force in Pakistan and contributes 21.8% to gross domestic production (GDP), and is the largest source of foreign exchange earnings. It also plays a major role for obtaining high yield of crops and fruits on sustained basis. The forest cover ensures regular supply of clean water in rivers by protecting watershed areas of northern regions. The development of forestry and agriculture sectors is like a base stone in the development of industry, education, health and defense etc. The construction material, pulp, paper produce and various industrial uses of timber are forest- based (GOP, 2010). Every country of the world is suffering from the destruction of vertebrate pests, specifically . Sometimes, the damage caused by them results in extreme scarcity of food and malnutrition. Research and studies have proved that amount of food from the crops planted throughout the world do not yield what is expected because of severe damage caused by these pests, ultimately resulting in huge financial losses both on micro and macro levels (Singleton, 2003; Stenseth et al., 2003; Khan, 2010). The Indian crested porcupine (Hystrix indica) is a large herbivore and is considered to be a serious economic pest of crops and forest plantations (Ahmad and Chaudhry, 1977; Greaves and Khan, 1978; Roberts, 1997; Khan et al., 2000, 2010). Indian crested porcupine belongs to the order Rodentia of the class Mammalia. There are two families of : Hystricidae (Old World porcupines) and Erethizontidae (New World porcupines). The Old World porcupines comprise four genera, namely, Thecurus, Hystrix, Atherurus and Trichys. Of these, genus Hystrix is characterized by its large size, quilled fur, hairless sole and short limbs with five strong toes. The skull is massive with pronounced infra-orbital foramen, broad chisel-shaped and pale yellow incisors, each with a hypsodont tooth. Digestive tract is elongated having a cecum. The upper lip is cleft, with flat S-shaped nostrils, covered with velvety hair on their top. This genus includes twelve species, whose combined range extends over the whole Southern Europe, Africa and South Eastern , including Pakistan (Prakash and Rana, 1970; Grzimek, 1990; Nowak, 1991). Out of these, only two, namely, Hystrix indica (Kerr) and H. hodgsoni (Gray), are generally met within the

1 Indo-Pak subcontinent. H. indica is widely distributed in Pakistan. (Greaves and Khan, 1978; Roberts, 1997; Khan et al., 2007). H. indica is characterized by an average head and body, which measures up to 78-100 cm, from the head to the tail end. This specie weighs about 11-18 kg and its hair are highly modified into superimposed layers of spines or quills of different size/ form. Beneath the longer and thinner spines, lies a layer of shorter and thicker ones (Prater, 1965; Roberts, 1997). Each quill has brown or black bands, alternating with white bands. Spines vary in length throughout the body, with the neck and shoulder, quills being the longest and measure about 15-30 cm (Gurung and Singh, 1996). When the porcupine is excited, these quills usually get erected to appear like a prominent crest. The tail is covered with shorter quills, which are usually white in colour. Among these, there are longer, hollow and rattling quills used to alarm the suspected predators (Ellerman, 1961). There is a general belief that a porcupine can actually shoot-out its quills at the intruder, though it is not supported with scientific evidence. The incisors are very broad and powerful and appear yellow in colour. The feet and hands are broad, with long claws, which are mainly used for burrowing and digging purposes. H. indica has successfully adapted itself to live in irrigated areas, forest plantations of the Indus plain as well as in the desert lands of the Punjab and Sindh (Khan et al., 2000). The soil dirt raised embankments of barrage and link canals have provided them with the most suitable habitats for establishing permanent dens. It also commonly occurs in the ‘Pothwar’ plateau throughout its scrub-forest plantations as well as in the steppe mountainous regions of Baluchistan upto an elevation of 2,750 m, above sea level (Roberts, 1997). This species is found in Las Bela, Kirthar Range, Kalat, Panjgur, Sibi area as well as in the Murree Hills and Kohistan forests above Shogran. It has also been recorded from the main valley of lower Chitral, Swat, Bannu and the Kurram areas (Roberts, 1997). It is well distributed throughout the Jehlum and Neelum valleys of Azad Jammu&Kashmir (Ahmad, 1990), and has been recorded in moist temperate deciduous forests of Machiara National Park at an elevation of 3,200 m above sea level the highest point, so far, recorded of its distribution (Awan et al., 2004). The porcupine inhabits canal-side plantations, embankments of drainage channels and irrigated forest-plantations. Intensively cultivated croplands, along canals and drains, are

2 normally the main target of the porcupine depredations. They also often infest graveyards and mounds of scrapped soil in the corners of fields, in saline and sodic soil tracts (Arshad, 1987; Greaves and Khan, 1978). In , the Indian porcupine is found in all types of habitats, dry or humid, open-land, forest, rocky-hill areas and even in the undulating plains (Prakash and Rana, 1970; Atwal, 1979).

Porcupine has been recognized as a serious pest of forest plantations: man-made irrigated and natural. Therefore, in the all Forest Management Working Plans emphasis has been given for its management. As early as 1967 (Taber et al. 1967) common girdling of Morus alba, Melia azedarach and Dalbergia sissoo in crop lands of the Punjab and in the forest-plantations was observed. Greaves and Khan (1978) made a brief survey of the porcupine problem in irrigated forest- plantations of the Punjab (Pakistan) and quantified its damage to M. azedarch (52.5%), M. alba (24.3%) and D. sissoo (1.0%). Khan et al. (2000) recorded damage to Pinus roxburghii (60%) and Robinia pseudoacacia (42%) in different areas of the Tarbela Watershed Management Project. Similar porcupine damage to forest and reforested areas was reported by Ahmed and Chaudhry (1977). Farm forestry efforts are being badly affected by the porcupines. Seedlings of D. sissoo, Eucalyptus spp. and Bombax ceiba were observed being up-rooted just after their transplanting, a characteristic behaviour of Indian crested porcupine (Khan et al., 2000). In India, H. indica, as a vertebrate pest, cause damage to Acacia spp, Zizyphus mauritiana, A. catechu, A. leucophloea, Butea monosperma, P. roxburghii, A. indica, Eucalyptus spp, and up-rooting of young coconut plants (Sharma and Prasad, 1992; Idris and Rana, 2001; Girish et al. 2005). Sheikher (1998) recorded 90% debarkation of the young P. roxburghii planted along the hillocks in Himachal Pradesh, Killing 54% of these. In , H. indica is one of the important pests on reforestation in western oak forests (Fattahi, 1997). Indian crested porcupine has been recorded as a serious pest of the traditional as well as non-traditional crops, including fruit orchards, vegetables, flowering plants, forages etc. (Alkon and Saltz, 1985; Khan et al., 2000, 2007; Pervez, 2006). Crops of economic importance, such as, maize, groundnut and potato, are severely damaged in irrigated plains and mountainous regions (Ahmad et al., 1987; Brooks et al., 1988; Khan et al, 1997, 2000). Among vegetables; okra, pumpkin, carrot, bitter gourd and onion are badly damage by this pest (Pervez, 2006). Porcupine has been reported to damage extensively Cenchrus ciliaris,

3 Sorghum helpenese, cymbopogan jwarancusa and Eliomurus hirsutus species of grasses at Karluwala (Bhakkar), a desert land of the Punjab, which are being seeded to enhance its grazing capacity on sustainable basis (Khan et al., 2000). Gutterman (1982) recorded more than 17 geophytes and hemicryptophytes being consumed by porcupines. Khan et al. (2000) recorded porcupine damage to plastic tubes of the drip irrigation system which seriously effected water flow. Such damage has also reported from (Alkon and Saltz, 1985a). Porcupine tunneling into embankment of barrage and link canals, such as, Nara, Rice and Rohri canals, caused breaches of irrigation water and flooding of thousand of hectares of croplands. One such breach in Rohri canal in 2002 caused an estimated loss of some 3 billion rupees in 12 villages (Khan et al. 2007). Porcupines are basically herbivorous in feeding habits, but prefer the bark of certain tree species and also certain roots, bulbs and succulent tubers. They sometimes prefer feeding on ripened fruits. In Balochistan, they regularly excavate the bulbs of Eremurs aurantiacus, whereas in the Southwestern Punjab, they appear to prefer the bark of Bakain (M. azedarach), which is being attacked systematically. Their second preference, with respect to trees seems to be the mulberry (M. alba) plants and then, the mango (Mangifera indica) gardens. Trees with thick and rough bark are mostly shunned (Roberts, 1997; Khan et al., 2000). The Old World porcupines of the genus Hystrix, have been very little studied, because of their shy nature, nocturnal habits and their tendency to live in remote and inaccessible places (Roberts, 1997). The information, so for available, on its feeding habits and biology is insufficient and suggests a scientific based study for its control in the field. The present study has been designed to collect/analyze detailed information on the food preferences, feeding habits, extent and pattern of damage inflicted by H. indica, in different agro-ecosystems of the Punjab (Pakistan). The information thus generated will be utilized to develop control strategies.

Objectives of the Research 1. To study changes in its seasonal feeding behaviour in different agro-forestry systems. 2. To identify its food diversity in different agro-ecological zones of the Punjab. 3. To determine the nature and extent of the porcupine damage to different trees and cultivated crops.

REVIEW OF LITERATURE

Geographic Range: The Indian crested porcupine, H. indica, an species is both Palearctic and Oriental in distribution (Grzimek, 1990; Nowak, 1991). The species is found throughout central Asia, southeast and in parts of , including countries, like, India, Bangladesh, , Bhutan, Srilanka, Pakistan, Iran, , Israel, Saudia Arabia and . In Pakistan, H. indica is commonly found in man-made natural forest plantation, crop lands, sandy desert of Punjab and Sindh, in the hill tracks of Khyber Pakhtun Khwa (KPK) province, and it is abundant in steppe mountain areas of Balochistan (Nawaz and Ahmad, 1974; Greaves and Khan, 1978; Geddes and Iles, 1991, Roberts, 1997; Khan et al. 2000). Ahmad (1990) and Awan et al. (2004) reported its distribution in different parts of Azad Jummu& Kashmir, having been recorded in moist temperate deciduous forest of Machiara National Park at 3,200m elevation, the highest point so for recorded of its distribution in Pakistan. In addition to these areas, Roberts (1997) reported H. indica populations in the Murree Hills, Kohistan, Hazara, Malakand, Kaghan, Naran, Sawat valley, Bannu, Kurram and lower Chatral valleys, and in the forests above Shogran. Khan et al. (2000, 2007) provided evidences of the presence of H. indica in some irrigated forest plantations of Sindh and scrub forests in Powrhar Region of Punjab. Mia et al. (1988) reported its presence in Lasbelas, Kirttar range, Kalat, Panjgur and Sibi. Brohi et al. (2006) in a survey of small indicated the presence of porcupine in Hingol National Park. According to survey of the mammals conducted by Ghalib et al. (2007) this specie is found in Hingol and Chiltan Hazarganji National Parks of Balochistan. Morphometry: The average length of an adult porcupine from head to tail is 80-100 cm as recorded by Prater (1965). The adult porcupine weighs about 11-18 kg. Its length from head to tail end is 78-100 cm. Its hair are modified into spines/quills each quill has alternating bands of brown/black and white colours. Beneath the longer and thinner spine there is a layer of shorter ad thicker ones. The length of spines varies throughout the body. The longest spine

5 measures about 15-30 cm (Gurung and Singh, 1996). On the tip of quills, there are hollow and microscopic barbs. Gurung and Singh, 1996; Kurta, 1995; Rose, 1989; Sweitzer and Berger, 1997; Vaughn et al., 2000, reported that quills vary in length at different sites of body. The neck and shoulder quills are longest measuring 15-30 cm. Ellerman (1961) studied that tails of Indian crested porcupine contain some longer, hollow and rattling quills having the purpose to alarm potential predators. Some quills of the tail are short and white. Sever and Mendelssohn (1991) studied average weight of 10 adult porcupines, collected from coastal plains and Israel, and reported it to be 13.9±2.2 kg. Agrawal and Chakraborty (1992) studied porcupines from Indian plains having maximum weight about 17-27 Kg. According to Roberts (1997) its adult male weighs about 11.3 kg in Pakistan. Burton (1915) recorded its weight about 15 kg. It has broader hands and feet with long claws, used for burrowing. The morphology of skull has been studied by Grzimek (1990). According to him there are pocket like inflations prominent in skull, lower jaw, lacrimal and turbinate bones. Infraorbital foramen arises from the frontal surface of snout (hystricomorphous condition). It is enlarged to extend masseter through it. Nasal cavity is enlarged. Shin and call bones are fused. Collar bone is greatly reduced. Angular portion is inflicted on the lower jaw. There are five teeth in each jaw i.e. one incisor, one premolar and three molars. Prominent diastema allows the lips to be drawn in while gnawing (Vaughn et al., 2000). Mian et al. (2007) observed that unlike other rodents the incisors of porcupine are active to its maximum size upper/lower, 3.0/4.5 and 2.5/4.5 cm in male and female respectively during adulthood. So lower incisors are significantly (P<0.05) larger than the upper ones both in male (3.81±0.10 cm Vs 2.24 ± 0.07 cm) and female (3.72±0.08 cm Vs 2.12 ± 0.04 cm). They observed the mean length of porcupine to be 83.28 ± 1.98 cm (male = 82.34 ± 1.52 cm, female = 84.17 ± 2.46 cm). According to them forelimbs of H. indica are significantly shorter than hind limbs both in case of male (17.52 ± 0.73 cm Vs 20.64 ± 0.69 cm) and female (17.77 ± 0.66 cm Vs 21.50 ± 0.82 cm). Damage: i. Forest trees In Pakistan, and else where porcupine damage to forest trees, crops, fruits and vegetables and natural resources have been studied and documented by the various workers.

6 As early as 1927, McDonald (1927) reported that in Cawnpore (Kanpur) Afforestation Division in India porcupine damage to trees was alarming. Damage to young rubber plants in southern India was noted by Pillai (1968). Sheik (1993) reported that H. indica damages the forest plantation of any stage from seed to mature tree. Porcupine damage to vegetation involves a wide variety of cultivated and wild plants and consumes both surface and sub- surface material (Gutterman, 1982, Alkon and Saltz, 1985; Ahmad et al. 1987; Brooks et al., 1988., Khan et al., 2000; Pervez., 2006). The porcupine inflicts injury to trees by gnawing the bark and through the multiple injuries completing the girdling of the tree trunk, exposing it to parasitic, fungi, termites and borer attack (Boddicker, 1983). The earliest report of damage by porcupine (Erethizan dorsatum) was by Storm and Halvorson (1967) who studied the effect of injury on radial growth of ponderosa pine, Pinus ponderosa, in western Montana, USA. On the basis of incremental borings, Krefting et al.(1962) estimated 45% reduction in the 10- years radial growth of Erethizon damaged timber trees. In Pakistan, Nawaz and Ahmad (1974) calculated a loss of increment amounting to 3853 cubic meter of wood in various blocks of Change Manga plantation. Greaves and Khan (1978) estimated economic loss of US$ 25/ha. in Changa Manga plantation. Khan et al. (2000) calculated economic loss of US$ 60-75/ ha. in various irrigated forest plantation of the Punjab. In Pakistan various workers investigated porcupine damage to irrigated plantation and quantified damage to different tree species. Taber et al. (1967) reported a common occurrence of girdling of M. alba, in the crop lands of Punjab, while Ahmad and Chaudhry (1977) reported serious damage to M. azedarach in five plantations. Greaves and Khan (1978) made a survey of quantified damage to M. azedarach (72%), M. alba (50%) and D. sissoo (4%) by porcupine in Chichawatni. Earlier to this, Nawaz and Ahmad (1974) studied the tree species susceptibility and percentage of damage by porcupine in five randomly selected blocks in Changa Manga irrigated forest. Porcupine, on the average, caused 15% plantation damage: M. azedarach (52.5%), M. alba (24.49%) and D. sissoo (1.02%) in performance order. Khan et al. (2000) gave further information of the impact of porcupine on forestry resources of Pakistan. While surveying Daur, Unhar and Kunhar Divisions of Terbla Watershed they studied the chirpine (P. roxburghii) and robinia (R. pesudoacacia) seedlings

7 1-2 years of age, planted at the density of 1,075 trees/ha. The damage to chirpine (P. roxburghii) ranged from 30-90% (X=60%) and to robinia (R. pseudoacacia) ranged from 10- 90% (X=42%). This substantial mortality of tree stocking was not astonishing, as a similar study in Himachal Pradesh, India, reported 54.4% mortality of P. roxburghii (Sheikhar 1988). Hussain (2004) observed that the damage to the chirpine mature trees was negligible, only partial debarkation of roots and stems was noted. However, the damage to chirpine plantation < 6 years of age was vulnerable to porcupine in Sherwan area of Terbela Watershed. According to information provided by forest officials, the material cost of raised transplantation of Chirpine, excluding the cost of time/season, establishment, transportation and other resources, is Pak Rs. 8/ plant. Based upon these two studies average mortality rate was 40%. The total economical loss was Rs. 3440.00 or about US $ 58/ha. If this is applied to five divisions of Terbela Watershed, annual economic loss may run into millions of rupees. Mishra and Khan. (2000) studied the rodents and porcupine which are injurious to forests and reported damage to coniferous and broad leafed tree species in various states of India. Earlier to this, Sharma and Prasad (1992) reported damage to Acacia spp, Zizyphus mauritiana, A. catechu, A. leucophloea, Butea monosperma, P. roxburghii, A. indica, Eucalyptus spp. Idris and Rana (2001) studied the extent of damage and factors leading to the damage of plants by porcupines, near Aavaclli hill, Jodhpur India, where damage by porcupine was restricted to epidemical layer only. They recorded neem plant damage upto 12% and Eucalyptus spp. in May and June near Mandal north hills, India. Some biotic factors eg. extreme heat and non availability of water cause extensive damage of plants by porcupines. Mian et al. (2007) studied the debarking of mature trees of different species in eight irrigated plantations of Punjab. Incidence of damage to E. camaladulensis, D. sissoo, and M. alba averaged 9.36, 10.82 and 8.02%, respectively, and overall damage estimated was 9.4%. They observed that the degree of damage to different specie between the plantations was significant. Also, no damage to mature trees of A. modesta, Populus deltoids, B. ceiba, and Tamarix Sumba was recorded in any plantation. Further to it, Mian et al. (2007) estimated porcupine damage to nursery plants of D. sissoo (9.85%), B. cieba (22.05%) and M. alba (14.97%). They did not record porcupine damage to nursery plants of A. modesta. Ahmad

8 and Chaudhry (1977) and Greaves and Khan (1978) observed the same type of damage to nursery stocks of the species in different plantations. Reports from India indicate that 30% seedling of Neem (A. indica) and 12% of Eucalyptus spp. were damage by cutting the plants at 5-7 cm above the ground level in Aravelli hill near Jodhpur (Idris and Rana, 2001; Girish et al., 2005). ii. Fruit trees: Damage to fruit trees by H. indica has little been assessed. Greaves and Khan (1978) recorded that citrus trees in orchards around Chichawatni suffered 20% damage. A farm, located near Fateh Jang, lost 200 young plants of mango (Mangifera indica) due to severe porcupine attack. Similarly, a farmer had to remove more than 500 citrus trees, which were severely debarked and girdled from a farm located in Islamabad. Pervez (2006) estimated H. indica damage to different fruit trees in Balochistan. He estimated porcupine damage to Ficus carica (7.7%), Carica papaya (16.67%), Pistacia spp. (5.0-28.85%) and grapes (1.20%). His data indicated that apples and wild pistachio are severely damaged. During winter, apple fruit, stored in pits in open area, is also known to suffer a severe damage in Kalat (Balochistan). Seed and seedling of mango, horse chestnut and almonds in nursery have been observed to be heavily damaged by removal of seed and uprooting through diggings (Aziz Khan, per. Comm.). Field Crops and Vegetables: Although, H. indica severely damage crops and vegetables but only few studies have been conducted and losses estimated. Crops especially maize, potatoes, melon, sugarcane and groundnut are highly susceptible to porcupine attack Roberts, (1997). Brooks et al. (1988) estimated 0.21% damage to groundnut plants by porcupine. They anticipated that as many as 30 to 40 plants may be up rooted in one night. Ahmad et al. (1987) recorded insignificant damage of 0.4% in 22 maize fields in Faisalabad district. This level of damage looks underestimated due to smaller sample size. In mountain areas of AJ&K heavy porcupine damage to maize crop was observed by Khan et al. (1997) and a little damage to rice and wheat crops. Alkon and Saltz (1985) estimated the total potato damage at 1.3 tons/ha, or 0.6% of the crop valuing US$ 30.0/ha. in irrigated fields in the Negev desert of Southern Israel. In Italy, porcupines are pest of cultivated crops such as maize, chickpeas, potato, beets,

9 cabbage, water melon and onion (Valier, 1991).Khan et al. (2000) estimated porcupine damage in 2.5 ha potato field 2 weeks before harvest and calculated a loss of 17.6% of the total production. They estimated that 270 kg of seed was lost due to porcupine damage. Pervez (2006) estimated 2-20% damage to potato crop in Balochistan, much higher damage (4-36%) was recorded in case of sweet potato. Mian et al. (2007) suggested by their studies that maize and potato were seriously damaged by H. indica. The estimated damage of 8.5±0.96% was recorded over 2.35 ha of wheat crop in Pothar belt. The damage was recorded higher (20.2±7.20%) in periphery of fields than in the center. Damage to onion was estimated 0.9-5.4% in different area of Bhakhar. Khan et al. (2000) studied the saffron (Crocus sativa) plantation at Mastung, Balochistan. There porcupine damaged bulbs through digging, 15-20 digs/day were recorded and total estimated loss was US $ 20-40/ha/season. Similarly in one of the floriculture orchard of Islamabad, the damage to iris, tulip and gladeolus estimated ranged from 50- 70%/season. Range Lands and Vegetation: Gutterman (1982) studied the impact of porcupine digs and digging on microhabitat, vegetative conditions and landscape. He recorded more than17 geophytes and hemicryptopytes being consumed by porcupines. Gutterman and Herr (1981); Alkon (1999) explained that porcupine diggings facilitate trapping of seeds, organic matter and water, promoting germination and growth of annual plants especially in arid areas. However, digging also enhances flow of water causing erosion of soil and soil nutrients from watershed and hilly areas. At Karluwala desert range, Bhakhar (Punjab) studies conducted by Khan et al. (2000) revealed that five species of grasses (Pennisetum spp., Cenchrus ciliaris, Elionurus histus, Cybopogan jawarancusa, Sorghum helpense) were severely damaged by porcupine digging. The grazing capacity of the range lands is, thus, being effected. Valier (1991) reported in Sicily the eating the bulbs of red quill (Urginea maritime) with out harm. It does, however, feed on rhizomes of such toxic plants as Arum maculatum and the tuber of Tamus communis and Cyclamen europaeus. Awan et al. 2004 observed that tubers of Arisaema jacquemontii and roots of Convolvulus arvensia were consumed by porcupines.

10 Distribution and habitat utilization: The Indian porcupine is highly adaptive and efficiently exploits various environments. The Indian crested porcupine is fossorial, dwelling in caves, and is highly adaptable to variable environmental conditions. They are usually found in rocky hill sides, in tropical and temperate scrublands, desert lands, grasslands and forests. For burrow development they require raised hillocks/embankments close to foraging habitat. Champion (1927) described the nocturnal habitat of porcupine in Himalayan hill station. Gurung and Sing (1996) survey indicated that Indian crested porcupine is distributed throughout Himalayas upto the elevation of 2400 m above sea level. Awan et al., (2004) recorded its highest point (3200 m) of distribution in the Machiara National park, AJ&K. Grzimek (1990) described the favorable habitats of porcupine including tropical and temperate scrublands, croplands, grasslands, sand dune deserts and forests. So they are highly adaptive and exploit various environments. In Pakistan, historically, porcupines utilized scrub forest, irrigated plantations, and moist deciduous temperate forest and desert lands. In Punjab, all irrigated and scrub forests, embankments of barge and link canals are heavily inhabited with porcupine. With the expansions of irrigation the porcupines have expended their distribution in to the crop lands. The information on population structure and burrow density are scanty. Nawaz and Ahmad (1974) calculated 2.4 porcupines/ burrow in the Changa Manga plantations. Different reports suggest different number of individuals sharing a porcupine den. Roberts (1997) reported the presence of 10 porcupines in a single burrow system, while Arshad (1987) suggested an average of 4 porcupine/ burrow. Khan et al. (1990) estimated the burrow density in different habitats of flood protection and railway embankments, dirt mounds, sandy scrubs and graveyard as heavily infested (7.14/ ha) as compared to the embankments of drainage (0.68/ ha) and irrigation canals (1.25/ ha). The average burrows density of 0.80/ha in forest plantation was estimated. Sever and Mendelssohn (1991) estimated a density of 0.04/ha for Negev desert in Israel with male: female ratio 2:1. Kayani et al. (1990) estimated the burrow density 0.05/ha for forest plantation of central Punjab. Pervez et al. (2005) reported three major habitats of H. indica in Pakistan i.e., mountain and Pothar, irrigated forests; and sandy deserts, having population density of 0.98 ± 0.2/ha, 0.67±0.1/ha, 0.15±0.7/ha., respectively. Arshad (1987) reported 4 porcupines/ burrow

11 while Roberts (1997) reported the presence of 10 porcupines in a single burrow. On an average burrow density estimated was 0.56 ± 0.17/ha, though a very high density (0.98 ± 0.20) appeared in rain-fed areas of Potohar belt followed by embankments of link canals (0.98 ± 0.20), irrigated forest plantation (0.21 ± 0.01) and desert rangeland (0.15 ± 0.07) (Mian et al. 2007). Food and Feeding: Only limited studies have been conducted on the food and feeding behaviour of H. indica. According to Blanford (1888-1891) and Flower and Lydekker (1891) porcupine is particular in its choice of food. It feeds on the roots of vegetables like sweet potatoes, potatoes, onion, carrot and fruits. It mostly attacks seedlings, saplings and boles of forest trees and roots and bulbs of succulent plants, uproots and clips nursery seedlings and saplings. Hanson et al. (1999) and Ben-David et al. (1997) suggested that dietary habit of porcupine is related to temporal and spatial variation of food availability. Prakash and Rana (1970) reported that feeding habits of porcupine is not species specific. They change their diet from habitat to habitat and from time to time. Smith (1982) conducted his studies in Pullman (USA) he described the seasonal and nocturnal variation in the feeding behavior of porcupine. The porcupines preferred large trees within ponderosa pine (P. ponderosa) or Douglas fir (Pseudotsuga menziesii) dominated subunits of a mixed conifer/pine grass. Harder (1979) conducted studies about winter feeding by porcupines (E. dorsatum) in mountain forest south-Western Alberta (USA) on Douglas fir (P. menziesii) and limber pine (P. flexilis). The pure stands of Douglas fir were preferred. Speer and Dilwerth (1978) conducted studies in central New Brunswick (Canada) during 1973-1974 and 1974-1975 on winter food utilization by American porcupine (E. dorstum). The porcupines feed preferably on the bark of spruce, white pine (P. strobes), eastern larch (Larix laricina) and gray birch and 91% on the bark of conifers. During the spring and fall season bark feeding is preferably on the eastern larch, white cadar (Thuja accidentalis) is preferred while feeding on twigs. In the wintering areas feedings on 3% of the trees occurred as compared to 0.13% in the randomly selected control plots.

12 Alkon and Saltz (1985) reported the foraging habits of porcupine (H. indica Kerr) on the cultivated potatoes in the Negev desert of the highlands of southern Israel. The ecological impact of porcupine on potato cultivation was assessed. The fasting feed on potato tubers at a rate of 530 ± 37 g in first 45 minutes and 148 ± 42 g/hr thereafter, the captive porcupine feed at a rate of 0.9 ± 0.2 g/bait. Potatoes cultivation is only a natural food and water supplement for porcupine. Their energy balance cannot be maintained only on potatoes. The Indian crested porcupine is herbivorous as it feed on vegetative materials (both wild and agricultural crops) of all kinds including fruits, grains and roots (Prater, 1965). Roze (1989) stated that nocturnal feeding habit of porcupines provide them additional nutrition due to night time metabolic process. Nowak (1991) and Pigozzi and Patherson (1990) described that these pests attack the agricultural crops due to their vegetation preference and can travel significant distance in search of food. Gurung and Singh (1996) and Prater (1965) suggested that vegetative material is not sufficient to fulfill the mineral requirement like Calcium which supports the growth of quills. The porcupine consumes insects, small vertebrates and carrion for this purpose (Nowak, 1991; Grzimck, 1990). Plant tissues are grinded efficiently by high crowned teeth with plain chewing surfaces which are later digested in stomach. The undigested material is retained in enlarged appendix and anterior part of large intestine where these are broken by microorganisms (Grzimek, 1990). Alkon and Saltz (1988) analyzed that the fecal pellets of porcupine contain a substantial amount of plant fiber that can be differentiated into identifiable parts of roots, shoots and twigs. Felicetti et al. (2000); Fournier and Thomas (1997); Roze (1989) suggested that porcupine has the ability to save nitrogen through faeces. Due to longer stay of the food matter in the digestive system, it can digest high fiber food better than some other hindgut fermenters of ruminants. Gulterman (1982) reported in Negev (Israel) that the porcupines consumed storage part of 12 species of geophytes and hemicryptophytes. Alkon and Saltz, (1985), reported the consumption of potatoes, pepper, fallen fruit and other agricultural crops. Harrison (1972), Freyc (1974); Gorbunov (1985) proved by the study that porcupine is adapted to consume

13 below ground plant biomass. Chaudhry and Ahmad (1975 b) recorded that porcupine feeds on the roots and barks of succulent plants in Pakistan especially bulbs of Eremurus auranhiacus, melons in Balochistan. They prefer bark of Persian Lilac (M. azedarach) followed by mulberry (M. alba) and mango (M. indica) in Punjab (Roberts, 1997), onion and carrot in India (Agrawal and Chakrabovty, 1992). According to Sarwar (1990) the diet of porcupine in center Punjab (Pakistan) consists of crops (corn seeds and cobs, sugarcane, wheat, rice), vegetable (musk-melon, bitter-gourd, potatoes, peas, sweet potatoes, chilies and pumpkin), grasses and fruit, tree leaves, bark and roots of different trees. Roberts (1997) suggested that porcupines are herbivorous, but they mostly prefer the bark of certain tree species as well as roots, bulbs and succulent tubers while maturing. They also attack ripe fruits. In southwest Punjab their preference order is: bakain (M. azedarach), M. alba and mango (M. indica). In Punjab they also attack the agricultural crops occasionally sugarcane crop. In Balochistan, they excavate the bulbs of Eremurs aurantiacus. According to Ahmed et al. (2003) in lower Sindh (Pakistan) porcupine consumed the parts of xerophytic plants species. Girish et al. (2005) found porcupine feeding on 37 species of cultivated and wild plants, apart from cultivated palms. The species also debark wild and cultivated palms such as coconut, areacanut and species of phoenix palms. Arshad et al. 1990; Bibi, 2004; Pervez A., 2005, conducted direct study on porcupine food through stomach contents and fecal analysis. The analysis of gut contents showed the presence of leaves, fruit, bark, roots of different crops, vegetable, grasses and trees. Inayatullah (2006) conducted study in Tarbela watershed areas and reported that porcupine depends upon minimum of 29 cultivated and wild plant species, and the preferable species included M. azedarach, P. roxburghii, Zea mays, S. helepense and Triticum aestivum. Mian et al. (2007) reported that porcupines are totally herbivorous and found seasonal and geographical variation of plant species. They analyzed 26 vegetation species of stomach contents and fecal pellets. The more frequently consumed species include Prosopis juliflora (20.79%), Z. mays (12.80%), Arachus hypogea (10.9%), T. aestivum (5.12%), Z. mouritiana (4.72%), Hordeum vulgare (4.26%), and S. vulgaris (4.03%). Less consumption was observed in the species like Solanum melongena (2.96%), Dicanhicem annulutum (2.90%),

14 Capsicum annuum (2.51%), Fumaria indica (1.75%), Brassica compestris (1.68%), Tribulus terrestris (1.51%), Allium cepa (0.70%), M. alba (0.70%), Convolvulus arvensis (0.52%), Cynodon dactylon (0.41%), Asphodeulus tenuifolis (0.41%), Salvia moorcrofliana (0.34%), Boerhaavia procumbens (0.20%), Cucumis melo (0.16%), Linaria vulgaris (0.16%), Solanum tuberosum (0.15%), Brassica obracea (0.05%), Dodonaca viscose (0.04%), Cyprus rotundus (0.03%) and M. indica (0.01%). Cotton thread, human hair and porcupine quills were also isolated from stomach contents as fragments. Both male and female species have same selection of food. Mian et al. (2007) analyzed 24 fecal pellets, collected from different tracks. Most commonly consumed food items include S. vulgare (15.16%), P. juliflora (12.46%), H. vulgare (11.04%) and T. aestivum (7.68%). Amjad et al. (2009) observed in Sindh that porcupine extensively consumed agricultural crops including Pisdium guajava (Gava), Ccucrbite maxime (Pumpkin), and Solamum melongera (Bringal). The food of Indian crested porcupine was comprised of 66.7% vegetable matter, 3.9% tuber/roots, 46.3% leaves/stem and 16.5% fruits. Behaviour: Grzimek (1990) and Felicioli et al. (1997) suggested that social life of porcupine is based on monogamy and long intensive care of young ones. According to their studies small family group shares the same burrow system including adult pair with infants and juveniles. Nowak, (1991) reported that females which bear young ones establish a separate den. H. indica are terrestrial rarely climbing trees, but are able to swim. They have strictly nocturnal behaviour even avoiding moonlight for foraging (Nowak, 1991; Bruno and Riccardi, 1995). Sever and Mendelssohn (1991) described the good memory and learning behaviour of porcupines. Animals have been trapped once in a trap (in open place/drainage pipe) can never be recaptured again at the same place even when attractive bait was placed. The second trapping is possible after five nights, while the third consecutive after 16 nights. Sever and Mendelssohn (1991) also suggested that porcupines do not exploit their entire home range every night but they choose a target area according to the availability of food, returning to the same den. Saltz (1985) explained that home range exploited during different nights is variable, average length of nocturnal course in deserts was 5.534 ± 1.781 m. Both sexes display the same behavior. Roberts, 1997, reported that food is recognized by sense of smell

15 and long vibrissae while feeding in agricultural tracts in several neighboring areas. The sense of hearing is also very sharp. Ellerman, (1961) and Nowak, (1991), reported by their study that when H. indica is alarmed/irritated it raised its quills and rattles the hollow spines on the tails. If the stimulus is persistent, it may attack by clashing its rear part against offender and driving its spine deep into enemy even causing severe injury or death of enemy including lion, leopard and hyena. Roberts (1997) reported that the species have graceful movement while walking slowly using an alternating gait and probably a trot when running and can swim fairly well. Communication and Perception: Roze (1989, 2002) studied the communication among porcupines such as acoustic, chemical, visual and tactile. When threatened, porcupines warn the predator by chattering their teeth and produce a chemical odour. Male warns through fierce vocalization and also displays the white and black markings on its back and tail to show the presence of its weapon. Females communicate their readiness to males by vaginal secretions, urine marking and high pitched vocalizations. Tactile communication has been noted between aggressive males, between mates, and between mothers and their young ones. Reproduction: Direct studies on reproduction biology of H. indica are very limited. However a major part of knowledge on breeding behaviour in H. cristata comes from captive individuals. Nowak (1991) reported that breeding occurs from March to December in Indian zoos, July to December in Central Africa and throughout the year in London zoo. The captive females in South Africa produce litters throughout the year but appear from August to March with a peak in January. According to Nowak (1991) and Grzimek (1990) 1-2 offsprings are born in a grass lined chamber in a burrow system, after 35 days of estrous cycle and 112 days of gestation period. Shortly afterward or at birth the young ones, eyes are opened and incisors are completely broken through (Grzimek, 1990). Its body is covered with small hairs and back spines are soft, sensing bristles projecting far beyond spines (Grzimek, 1990). Its birth weight is only 3% of the mother’s body weight and its spines begin to harden within one week making it able to leave den first time, it begins to feed on solid food within 2-3 weeks.

16 Van Aarde, 1987, reported that females of H. africaeaustralis conceive once a year as normal ovarian cycle starts (from 2-42 days after the end of lactation period, but 3-7 days elapse before conception, each cycle is about one month long 32.3 ± 4.6 days, n= 18). During these sterile cycle less studies are available about the hormonal changes, although the progesterone concentration during sterile mating is 0.9 ± 0.5 mg/ml n = 6, while during mating followed by conception its mean level is 3.2 ± 1.0 mg/ml n = 3. This is significantly higher (P<0.01) than that of sterile period. The two conceptions interval is one year and the interval between litters is approximately one year (gestational length = 93 days, lactational anoestrus = 101 ± 37.8 days) 25 intervals have been recorded between litters for parous females which varied 110 – 500 days. Young ones born after an interval of <200 days (n = 3) do not survive, on an average their life is 345 ± 66 days (n = 22). This is not due to physiological limitation of mother but due to interference of proceeding litters who prevent them from sucking. The females must yearly conceive to produce a litter with high chance of survival. Van Aarcle and Skinner (1986) studied the male reproductive tract and found that males attain sexual maturity (complete spermatogenesis) at the age of 8-18 months and remain sexually active throughout year. In pubertal males testosterone concentration is significantly higher than those recorded in sexually mature males. These Hystricomorph rodents don’t have true scrotum and penis is directed posteriorly and s-shaped when not erected. In most species surface of glans penis is covered with spines and spicules and characteristic suborder is produced by sacculus urethralis. Neither the hystricomorph males have been reported to be seasonal breeder, nor do their gonads regress periodically. In South Africa free ranging females produce litters in summer (Van Aarde, 1985). In male accessory glands including vesicular glands, prostrate gland and Cowper’s gland are well developed in adults. Prostrate gland consists of left and right lobes. Copulatory plug is formed by mixture of fluid of diverticulated seminal vesicles and prostrate secretion; captive females are polyestrous and non-lactating adults cycled throughout the year. They attain maturity at an age of 9-16 months and conceive first time when 10-25 months old. Parental Care: Currently available information on parental care is derived from studies on the tree porcupine, E. dorsatom (Roze, 1989; Sweitzer and Berger, 1997). Parental care and food is provided by mother for a few weeks of life. During day time, the baby remains hidden under

17 ground and mother rests in the trees. The baby porcupine and mother meet only at night. For six weeks baby follows mother for feeding. In the next couple of months foraging distances increase separation between them. But mother follows landmarks of porcupine every night by mid October; baby spends its first winter alone. The father does not play any role in rearing and caring of offspring’s and maintains little or no contact with offspring’s. Kurta, (1995) and Roze, (1989) determined the life span of porcupine as 18 years in the wild. Porcupine longevity is probably limited by life of their grinding teeth. Control: Various control methods both chemical and non-chemical, are being practiced or have been evaluated for the control of Indian crested porcupine. The most commonly used non chemical methods such as dog hunting, shooting and trapping are short term solutions and are mostly labour intensive and costly. Use of chemical compound for the control of H. indica have been tested and evaluated in Pakistan and elsewhere. Faulkner and Dodge, (1967) developed a control technique involving the use of sodium aresnite, granulated sugar and apple as fresh bait and obtained 71-93% kill of Canadian porcupine (E. dorsatum). Anthony et al., (1986) used strychnine-salt blocks for controlling porcupines in pine forests in Oregon and California. Only 4 out of 32 marked porcupines were killed. Boddicker (1983) reported the repellent materials that can be sprayed over plants to save from porcupine damage which included thiram or arasan formulation. Wagner and Nolte (2000) used Hot Sauce registered as a repellent for forest mammals. Porcupines (E. dorsatum) were not repelled by any concentration of Hot Sauce. Nawaz and Ahmad, (1974) obtained 83% success while conducting large scale operational research in Changa Manga plantations. They used aluminium phosphide and hydrogen cyanide. By applying these chemical compounds the porcupine damage of 14.67% in whole of plantations reduced to 0.026%. Some other studies involved the use of some toxic compound where complete control of porcupines was not achieved (Chaudhry and Ahmad, 1975 ; Arshad et al.,1988). In the field trials conducted by Khan et al. (1992) three fumigants and two acute poisons were used against the porcupines in forest plantations and crop lands. The use of a two-ingredient gas cartridge, followed by sodium cyanide and aluminium phosphide caused the highest mortality. Strychnine baits did not proved so effective as the fresh baits which

18 were made from sodium fluoroacetate (1080). Field trials were conducted by Ahmed et al. (2003) in order to determine the efficacy of aluminum phosphide (3g), sodium monofluroacetate (0.03%) and brodifacoum wax blocks (0.005%) against the Indian crested porcupine. He got the highest mortality (100%) after applying 4 tablets of aluminium phosphide (3g) followed by sodium cyanide. Khan et al. (2007) tried two poison baits i.e. (0.0375% coumatetralyl and 2% zinc phosphide) and two fumigants (carbon monoxide and calcium cyanide powder) against the Indian crested porcupine. With carbon monoxide, calcium cyanide and coumatetralyl 95.85, 96.52, 100% mortality was recorded while zinc phosphide proved a less effective bait. It was poorly consumed by porcupine and gave only 27.78% mortality. While checking the efficacy of coumatetralyl bait (0.0375%) against H. indica on a floriculture farm, Khan et al. (2008) recorded that the bait consumption increased up to 7th day which steadily decreased by 14th and completely decreased on 15th day. Hence, baiting resulted in 100% elimination of porcupine population. The research (Field trial) conducted by Mushtaq et al. (2008) determined the efficacy of aluminium phosphid (3g tablets). He achieved 100% reduction in burrow activity by applying eight tablets of aluminium phosphide/burrow, 85% with six tablets/ burrow and 75% reduction with four tablets/ burrow. In order to get 100% reduction in burrow activity in categorized burrows he used four tablets of aluminium phosphid in small (circumference 100.2+2.93 cm), six tablets in medium (127+0.93cm) and eight tablets in large sized (157+2.44cm) burrows. According to Khan et al. (2010) arsenic trioxide as a baiting method resulted in 89% reduction of porcupines occupying in treated dens. Four to ten tablets of aluminium phosphide were used for fumigation, with the results ; four tablets are ineffective five and six tablets partial control and complete control of porcupine was achieve by seven tablets. Khan et al., (2011) used two-ingredient cartridge for the release of carbon monoxide for controlling porcupine in the dens. The test results indicated 100 percent reduction in active porcupine dens with the usage of 250, 350, 375g cartridges in porous sandy, clay loam and silt loam soils having varied moisture contents.

MATERIALS AND METHODS

Study Area: The Punjab (27.5-34.1° NL and 69.5-75.2° E) is the north-eastern province of Pakistan. Leaving aside the northern parts, the main part of the province is plain, which mainly constitutes the central Punjab. The north-eastern parts of the province are extensively cultivated and thickly populated, while towards the south and the west the agriculture and human settlements become sparse. Under the recent development and constrains on the biotic resources, the agriculture has extended to the previously unexploited tracts through the development of irrigation network. The porcupine tract in the Punjab is constituted mainly by the tracts where the agriculture has recently extended and is relatively sparsely inhabited by the human population. For the purpose of present study, the prospective porcupine belt of the central Punjab has been divided into four ecological zones, i.e., rainfed Pothwar belt, irrigated forest plantation, embankments of link canals and desert. Most of the plain area of Punjab is irrigated through barrage and irrigational canals. Apart from the agricultural exploitation, vast areas in these tracts have been set aside for the development of irrigated forests by the Forest Department. Kundian (Mianwali), Shorkot, Changa Manga, Daphar and Lal Sohanra are some of the important irrigated forest plantations. Dapher and Shorkot plantations were selected for the study. Each plantation is divided into different subdivisions, blocks and compartments for administrative convenience. Each plantation has its own plant composition but Shesham (D. sissoo), Eucalyptus (E. camaldulensis), Frash (Tamarix aphylla) and Mulberry (M. alba) were the dominating tree species (Sheikh, 1995). Thal represent sandy desert ecosystem of Punjab. Annual precipitation in these areas is less than 75 mm and natural vegetation is scarce. Water table is generally very low. Rakh Goharwala and Rakh Chobara were selected for the desert ecosystem. Faisalabad and Qaidabad were selected for the agriculture lands. The canal irrigation extends in some areas, where irrigated agriculture is exercised; there are sufficiently large tracts under wild undulating sand dunes, even in the extensively irrigated/ arable tracts, which provide denning habitat for the porcupine. The embankments along the canals also provide favorite denning sites for the porcupine. Qadirabad-Ballokey canal was selected for the link canal ecosystem.

20 Study Period: The experiment was conducted between January 2008 to Jun 2010, the whole study period was divided into four seasons: Spring (February – April); Summer (May –August); Fall (September-October) and Winter (November-January). Trapping Method: The porcupines were trapped according to method of Hafeez et al., (2007). Penal trap used in this study is given in plate 1. Late in the evening, the traps were set at the mouth of active porcupine burrows with suitable bait materials placed inside it. Each trap was fixed with steel pegs in this position so that a trapped may not tilt it. The traps were checked early in the morning to collect the animal. Damage Assessment: A general idea on the type of the damage caused to different types of the vegetation was developed through general observations in the area and sharing the experiences of the local farmers. This helped in further designing the sampling techniques and its mode of operation for future studies. However, in forest plantations stratified sampling technique was used. i. Irrigated Plantation: The tree damage was assessed in two major forest plantations of the Punjab, Daphar (Gujrat) and Shorkot plantation. In each forest age-related types of plantations i.e. very young (< 1 years), young (> 2 years) and mature (5 or more years) were marked on the map, randomly selected compartments, representing each type of plantation were visited for a detailed survey. Every 5th row was selected and the number of damaged (with characteristic marks of gnawing) and undamaged trees were counted. In the case of mature trees, the plants having debarkation of >20% of the stem girth at b.h.d were regarded as damaged, as it is expected to seriously effecting the radial growth of the plant, affecting the quality of wood. For younger and or very young plants, the number of uprooted (associated with characteristic porcupine digging, Plate 6) and chopped off plants were considered as damaged. ii. Forest Nursery: In the study area two types of nurseries were observed for damage in forest plantations of Punjab, i.e., D. sissoo (Sheesham) and B. ceiba, (Simal). The quadrate (2x2 m²) technique was adopted for the damage assessment, where the normal verses uprooted plants were counted and damage estimated.

21 iii. Crops: The survey was done by driving roads traversing the selected crop growing area, using a road transect, stopping at every 5km if crops fields were available. At each stop, 4 fields were surveyed. Four quadrate samples were taken from each field, generally near the corners. The number of plants, both damaged and undamaged within the quadrate, were counted. The damage in the crop was assessed by randomly selecting four quadrate (two in the periphery and two some 50 m deep) of 1 x I m² for the wheat field. Onion (Bhakkar), melons (Bhakkar), and groundnuts (Quaidaabad) crops were sampled using 2X2m² quadrate. The normal and damaged plants (cut and chewed) were directly counted. The percentage damage was calculated using following formula: No. Damage plants % damage = ------× 100 Total no. of plants

Preparation of Reference Slides: In different seasons, plant species from different study area were collected. Reference slides were prepared following William (1962) and Ward (1970). The required vegetative parts of the plants were obtained and dried. These fresh specimens/dried tissues are soaked in plant soaking solutions (distilled water, ethyl alcohol, and glycerin (1:1:1)) for a night then washed with tape water for about 10-20min. each specimen of plant tissue was ground in virtis homogenizer with distilled water. These contents were poured in micro sieve. This micro sieve in composed of 6cm long hollow cylinder having 0.05mm mesh of stainless steel wire that is fitted with a rubber stopper at one end of cylinder in such a way that it could be left filled with 1% sodium hypochlorite for clearing the specimen and was kept soaked in a sodium hypochlorite solution of 5% Chlorax and 4 parts of distilled water (1:4) for 20-30 min. To neutralize the basic effect of sodium hypochlorite equal amount of dilute acetic acid was added to the tissues, were placed in mordant solution for 15-30min, and then this distilled water was dripped into the sieve to remove any basic residues. The contents were placed in hematoxylin stain for 10-15minutes then washed with tape water. On a clean slide a drop of Apathy of mounting medium (100cc distilled water and 100g gum Arabic) was placed. The stained plant material was mixed with this mounting medium with a wet camel brush and the material was uniformly spread over 22x40mm of

22 slide. Two drops of mounting medium were added to the plant material and were covered with glass cover of 22x40mm and press tightly with a peril eraser for uniform contact of glass cover and slide. Labeling of slider was done for identification and was left at room temperature overnight for fastening of material on these studies. The main features and cellular characteristic of each slide were studied and drawn on a note book as freehand drawing. Stomach Contents and Fecal Pellets Analysis: Stomach of each of the trapped animals was immediately removed, after immobilizing and mid ventral cut, which were legated on the both sides, and fixed in 10% commercial grade formalin and properly labeled with a field number. The field data on each individual like geographic location and date were recorded with reference to the field number. Samples were brought to the laboratory, where the contents of each stomach were removed and preserved in 10% formalin, in glass vials, for further analysis. The randomly selected parts of the stomach contents were cleared with running water over a sieve and placed in the Petri dish for macro-analysis. A white paper having equal-sized squares grid was placed below the Petri dish where the fragments recovered from stomach were spread as a single layer, each item was identified directly through macroscopic examination by comparing with the reference plants. The number of fragments of different species of plant in seven different randomly selected boxes was recorded. The relative frequencies contributed by different species were worked out by suitable pooling of the individual data The fresh fecal pellets (Plate 2) of the porcupine were also collected from different areas according to availability; packed in polyethylene bags, labeled appropriately and brought back to the laboratory, where these were stored at 40°C till their analysis. Representative samples of the dominating plant species were collected from each locality, brought back to the laboratory, identified and used as reference material for identification of the species recovered from the stomach contents and fecal pellets. Different parts of the reference plant specimens, i.e., stem, root and leaf, were soaked in the 70% alcohol for 2 hours and subsequently grinded using a pestle and mortar to the size of fragments frequently found in fecal pellets of the porcupine and stained with light green. The reference drawings of each sample of different species were developed and maintained for the analysis of the fragments recovered from fecal pellets, using prominent cell and other histological structures

23 through light microscopic examination and used for identification of the species recovered from the fecal pellets. . The fecal pellets were soaked in distilled water and washed with water over a mesh screen. The fragments left on the mesh were put in 70% alcohol for about 10 minutes and stained with light green dye to achieve differentiation. Permanent mounts were then prepared after passing through alcohol gradients. Seven focuses from each of seven slides, prepared from each fecal pellet, were examined under light microscope (60 X) and each piece in the focus was identified up to the lowest possible taxonomic category. The number of each species of plant parts in each box was calculated and the total number of the fragment was recorded according to method of Hansen et al., (1971). The overall percent relative frequency was calculated as:

Total number of fragments of a species Relative frequency (%) = ------ 100 Total number of fragments analysed

The relative frequency of different food items recorded from the stomach content was compared in different areas and seasons to work out the feeding preference of the species. The similar procedure was adopted for fecal pellet analysis. Statistical analysis: Level of significance of results was analyzed with the help of analysis of variance (ANOVA) using SPSS software at 95% confidence limit X ± 2 S.D. (SPSS, 1996). Diversity Index: To determine the degree of dominance of food items in the stomach samples, Berger- parker index (1970) was applied. To calculate index number (d), total number of fragments of each food item was calculated from the equation. d = N (max)/N Where N = total number of fragments of all food items and N(max) = number of fragments of the most abundant food items. In order to ensure that the index X (1/d) increases with the increasing diversity, the reciprocal of the index value (d) was used.

RESULTS AND DISCUSSION The porcupines are very cautious, human shy and basically nocturnal, making direct studies on feeding behavior is difficult (Roberts, 1997). H. indica is a large rodent having scattered populations and hence a limited degree of trapping is possible for obtaining the stomach contents. The fecal pellets however, can be collected from the field and be subjected to study. In Pakistan, only few short term studies feeding habits of H. indica have been conducted. An analysis of 131 stomachs contents and 480 fecal pellets revealed that 44 species of plants were consumed by the porcupine as food items. The Indian crested porcupine is covered under Schedule IV of Pakistan Wildlife Acts and there are no restriction on its hunting or Killing by any means. A season-wise distribution of these stomach samples and geographic variation are as following A. Seasonal feeding behaviour and geographic variation: a. Faisalabad: i. Spring: The analysis of spring samples of stomach contents (n=4) revealed that 15 plant species were consumed by porcupines (Table 1). Among these, Triticum aestivum with mean relative frequency of 21.62±1.45 was the most intensively consumed in this season. B. ceiba (12.58±1.31), Brassica campestris (9.19±0.60), Sorghum helpense (9.01±1.48) were in sufficient amount, while Solanum melongena (7.52±0.62), M. alba (7.31±1.04), C. dactylon (6.71±0.69), M. indica (6.01±0.62), E. camaldulensis (5.54±0.36), M. azedarach (4.74±1.46), Lathyrus aphaca (4.67±0.67), B. oleracea (4.26±0.00), Z. jujuba (4.04±0.00), Saccharum officinarum (3.69±1.36), D. sissoo (3.03±0.00) were utilized relatively less frequently. Unidentified fragments (2.47±0.41) and other fragment (2.58±0.27) of spring diet comprised of hair, spine and thread particles contributing significantly of the total contents. The percentage of food items (Figure 1) of spring diet of porcupine included T. aestivum (17.92%) was predominantly consumed species, as it constituted a larger percentage of total stomach contents. B. ceiba (10.43%), B. composures (8.27%), S. halfpence (9.13%), S. melongena (7.47%), M. alba (6.06% ), C. dactylon (5.56%), M. indica (4.38%), E.

26 camaldulensis (4.53%), M. azedarach (3.93%), L. aphaca (3.87%), B. oleracea (3.53%), Z. mouritiana (3.35%), S. officinarum (3.06%), D. sissoo (2.51%), unidentified fragments (2.05%) and other fragments (2.14%), were less consumed by H. indica. Figure 3 shows the percentage consumption of different food parts like stem, leaf, seed, spike, tuber, flower and pod recovered from the stomach of porcupine collected during spring season. Leaf (26.3%), spike (22.3%), stem (19.3%), seed (17.7%) and root (11.2%) were consumed with a high frequency while flower (2.00%) and tuber (1.1%) were eaten less frequently consumed. Fecal sample (n =15) were collected from different localities of Faisalabad during the spring season. The analysis of the fecal pellets (Table-2) revealed that T. aestivum was consumed at the highest mean relative frequency 29.37±1.33, while Hordeum vulgare (19.00±5.45), S. halepense (14.15±1.21), L. aphaca (11.67±0.00), M. azedarach (11.58±0.83), M. alba (11.08±2.23), B. ceiba (10.90±2.74), B. campestris (10.68±1.08) constituted sufficient portion of the diet. B. oleracea (9.88±1.93), D. sissoo (9.80±1.41), E. camaldulensis (9.74±1.83), M. indica (9.22±2.40), Pisum sativum (8.58±3.92), Melilotus indica (8.44±1.67), Z. jujuba (5.21±1.02), A. cepa (5.19±0.58) were recorded with different frequency. Other matter (1.52±0.00), unidentified plant parts constituted (7.51±0.53) and unknown plant parts (10.00±0.65). This confirms the reports of Arshad et al., (1990) who provided some information about the diet of H. indica in the 30 km radius around Faisalabad. Regarding analysis of the fecal pellets, the percentage of the food items (Fig-2) revealed that T. aestivum was consumed at the highest percentage (14.43%), while H. vulgare (9.34%), S. halepense (6.95%), L. aphaca (5.73%), M. azedarach (5.69%), M. alba (5.44%), B. ceiba (5.36%), B. campestris (5.25%), B. oleracea (4.85%), D. sissoo (4.82%), E. camaldulensis (4.79%), M. indica (4.53%), P. sativum (4.22%), M. indica (4.15%), Z. mouritiana (2.56%), A. cepa (2.55%) other matter (0.75%), unidentified (3.69%) and unknown plant parts (4.31%) were the spring diet of the porcupine. Figure 4 shows the percentage consumption of the percentage different parts of the plant species. Spike (32.9%), stem (22.3%), seed (17.2%) and leaf (13.7%) appeared with higher frequency.

27 ii. Summer: During the summer season stomach contents of (n= 5) animals were examined (Table 1). Analysis of stomach contents of these specimens revealed that 19 types of food items of plant origin were consumed by the porcupine. Among these Z. mays (17.38±1.25) and S. vulgaris (17.35±0.86) were predominant, as it constituted larger amount of total stomach contents followed by P. juliflora (13.40±0.00), M. alba (8.91±0.00), M. azedarach (7.92±0.80), L. esulentum (7.81±0.74) but were utilized relatively less intensively. Among other items eaten C. maxima (6.70±3.61), C. dactylon (6.36±1.10), B. ceiba (6.19±0.00), Cucumis melo (5.36±0.28), L. aphaca (4.95±0.00), C. rotundus (4.08±0.42), E. camaldulensis (3.78±0.34), S. halepense (3.09±0.00), M. indica (3.06±0.03), M. indica (3.05±0.04), D. sissoo (2.72±0.37), P. guajava (2.54±0.56), A. cepa (2.06±0.00) were occasionally consumed. In the summer diet of the porcupine other matter like hair and spine constituted (2.56±0.31) whereas unidentified plant food (3.68±1.62) and unknown matter was (5.87±0.49). During this season maize is widely cultivated and severely damaged by porcupines (Ahmed et al., 1987). The percentage of analysis of stomach content of plant origin included Zea mays (12.52%) and S. vulgaris (12.50%) were predominant, as these constituted larger percentage of total stomach content. P. juliflora (9.65%), M. alba (6.42%), M. azedarach (5.71%), L. esulentum (5.63%), C. maxima (4.83%), C. dactylon (4.58%), B. ceiba (4.46%), C. melo (3.86%), L. aphaca (3.57%), C. rotundus (2.34%), E. camaldulensis (2.12%), S. halepense (2.23%), M. indica (2.20%), M. indica (2.20%), D. sissoo (1.96%), P. guajava (1.83%), Allium cepa (1.48% ), other matter like hair and spine constituted (1.83%) whereas unidentified plant food (4.23%) and unknown matter was (2.65%).

Stem (27.9%), seed (16.0%), spike (14.7%), leaf (12.5%) and root (10.2%) were recovered with high frequency. Flower (9.8%), tuber (6.5%) and pod (2.1%) were less frequent. (Fig .3) All the (n =15) samples collected in the winter season were taken in the months of November, December and January. Seventeen type of food items of plant origin were recovered from fecal sample collected in winter (Table 2). T. aestivum (23.23±2.23) was present in sufficient amount, while H. vulgare (20.75±4.83), B. ceiba (15.71±0.96), C. dactylon (15.01±1.15), S. halepense (10.57±1.17) were also recorded sufficiently. E. camaldulensis (8.48±0.73), M. azedarach (8.48±0.65), B. oleracea (7.63±1.28), M. alba (7.37±1.25), P. guajava (7.15±1.25), M. indica (6.61±0.35), S. vulgaris (6.12±0.64), A. cepa (4.70±1.09), S. officinarum (4.21±1.02), C. rotundus (2.51±1.12), Z. jujuba (1.60±0.21) were less frequently obtained. Other matter (4.17±0.00), unknown plant parts were identified in significant percentage (8.60±0.65) and unidentified fragments found (7.24±0.55). The percentage of the food items in fecal samples collected during winter season, T. aestivum (13.11%), while H. vulgare (11.71%), B. ceiba (8.86%), C. dactylon (8.47%), S. halepense (5.96%), E. camaldulensis (4.79%), M. azedarach (4.79%), B. Oleracea (4.31%), M. alba (4.16%), P. guajava (4.03%), M. indica (3.73%), S. vulgaris (3.45%), A. cepa (2.65%), S.

31 officinarum(2.36%), C. rotundus (1.42%), Z. jujuba (0.90%), other matter (2.35%), unknown plant parts were (4.85%) and unidentified material found (4.09%). The analysis of fecal pellets (Fig.4) suggested that stem (29.7%) were represented in sufficient amount. Spike (17.9%), seed (16.0%) and root (10.3%) contributed a significant part of total fecal contents. Tuber (6.6%) and pod (5.5%) appeared with low frequency in fecal pellets. It confirms the finding of Roberts (1997), Arshad et al. (1990) and Brooks et al. (1988).

Unidentified food items (4.54±0.44), unknown plant parts were (7.44±0.78) and other food items (1.92±0.36) of winter diet comprised of hair, spine and thread particles. Mac Mahon (1985) observed the winter feeding habits of porcupine and he suggested that it consumed bark of different trees, including pines, fir and hemlock. The percentage of the food items of the stomach contents during winter seasons, recorded; T. aestivum (8.10%) and P. juliflora (7.71%) were most intensively consumed species. A. cepa (6.72%), B. ceiba (6.33%), H. vulgare (6.23%), M. indica (6.17%), S. halepense (5.78%), B. campestris (5.37%), M. alba(4.97%), P. guajava (4.58%), E. camaldulensis (3.96%), C. dactylon (3.29%), Z. jujuba (3.28%), S. officinarum (2.93%), D. sissoo (2.85%), B. oleracea (2.88%), S. tuberosum (2.46%), M. azedarach (2.41%), C. rotundus (1.83%), S. munja (1.54%), unidentified food items (3.41%), unknown plants parts were (5.68%) and other food items (1.47%) of winter diet.

M. alba (7.20%), M. azedarach (6.98%), L. esculentum (5.81%), E. camaldulensis (5.60%), L. aphaca (5.04%), C. dactylon (4.85%), C. melo (4.47%), S. vulgaris (4.69%), B. ceiba (4.19%), P. juliflora (4.08%), C. rotundus (3.23%), D. sissoo (2.75%), M. indica (2.55%), M. indica (2.40%), C. maxima (2.09%), A. cepa (1.80%), S. munja (1.50%) and other contents were (2.17%), unidentified material (3.11%) and unknown plant parts (5.61%). Figure 7 presents the summary of the food parts recovered from stomach of porcupine. Seed (24.7%), stem (20.4%), leaf (18.5%) and root (16.0%) recovered with higher percentage while spike (8.5%), tuber (8.0%) and pod (3.61%) were of less percentage. Analysis of fecal pellets showed that 18 types of food items of plant origin were consumed at different frequency by porcupine (Table14). Z. mays (19.14±1.18) and S. vulgaris (18.44±1.38) were the most intensively consumed species in this season. P. juliflora (11.78±1.23), C. dactylon (9.02±0.72), B. ceiba (8.84±2.52), M. alba (8.50±1.50), S. nigrum (7.58±5.76), M. azedarach (7.15±1.39), S. halepense (7.01±0.46), D. sissoo (6.07±0.98), E. camaldulensis (5.59±1.03), M. indica (4.93±1.18), C. rotundus (4.56±0.87), P. sativum (3.92±0.00), Z. jujuba (3.78±0.33 ), L. aphaca (3.31±0.18 ), S. munja (2.99±0.00 ), C. melo (2.94±0.89) constituted a significant proportion. Unknown plant (10.44±0.37) and unidentified particles (8.21±0.64) were found significantly. Other fragments (1.96±0.00) were found less frequently.

41 The percentage of food item in fecal samples during summer season showed (Fig-5) that Z. mays (12.26%) and S. vulgaris (11.81%) was the most intensively consumed species in this season followed by P. juliflora (7.54%), C. dactylon (5.78%), B. ceiba (5.66%), M. alba (5.44%), S. nigrum (4.85%), M. azedarach (4.58%), S. halepense (4.49%), D. sissoo (3.89%), E. camaldulensis (3.58%), M. indica (3.16%), C. rotundus (2.92%), P. sativum (2.51%), Z. jujuba (2.42%), L. aphaca (2.12%), S. munja (1.31%), C. melo (1.88%), unknown plant parts (6.69%) and unidentified particles (5.26%), other matters (1.26%). In fecal pellets, seed (24.3%) and stem (23.8%) were in high proportion (Fig-8). Spike (18.7%), leaf (16.9%) and root (10.8%) were found in sufficient amount. Tuber (5.4%) was appearing in less proportion. The presence of seed of different plant species confirmed the results of Arshad et al. (1990). iv. Fall: The fall sample of stomach contents (Table 3) showed the appearance of 14 plant species. Z. mays (20.48±2.56) was the most intensively consumed specie. S. vulgaris (12.68±4.65), P. juliflora (12.45±0.99), S. halepense (11.23±4.98) were recovered with high frequency. M. azedarach (8.93±0.00), B. ceiba (8.50±0.46), E. camaldulensis (7.60±1.33), D. sissoo (7.53±0.98), C. dactylon (6.33±0.23), C. melo (5.08±2.38), C. rotundus (4.54±0.77), S. officinarum (4.03±0.19), Z. jujuba (2.84±0.14), S. munja (2.44±0.81) were recovered in relatively less frequently. Other matters (2.54±0.26) were found to be less frequent while unidentified (5.07±0.52) and unknown plant parts were found relatively in significant amount (6.79±1.22). The fall sample of stomach contents (Fig-5) showed the percentage of the food items: Z. mays (15.87%) was the most intensively consumed species. S. vulgaris (9.82%), P. juliflora (9.65%), S. halepense (8.70%), M. azedarach (6.92%), B. ceiba (6.59%), E. camaldulensis (5.89%), D. sissoo (5.83%), C. dactylon (4.90%), C. melo (3.94%), C. rotundus (3.52%), S. officinarum (3.12%), Z. jujuba (2.20%), S. munja (1.89%) were recovered. Other matters (1.97%) were found in less percentage while unidentified (3.93%) and unknown plant parts (5.26%) were found. This confirmed the observation of Geddes and Iles (1991) that porcupine causes extensive damage to maize crops in the northern area of Azad Kashmir, Pothowar plateau. Z. mays consumption also support the observation of

42 Ahmed et al. (1987) who reported that damage conducted in maize fields in Faisalabad district was widespread. Leaf (23.6%) and stem (18.2%) were consumed with high percentage followed by seed (16.3%), spike (15.3%), root (13.7%), tuber (10.5%) and pods (2.2%). The analysis of fecal samples of porcupine collected during fall season showed that 18 types of food items of plant origin were consumed at different frequency (Tabl-4). Z. mays (16.75±0.91) and S. vulgaris (16.23±0.85) was the most intensively consumed species in this season. P. juliflora (12.91±1.34) appeared in high frequency. M. azedarach (9.17±1.08), C. dactylon (9.131.12), M. alba (8.69±1.52), M. indica (8.45±0.00), P. guajava (7.92±0.65), S. nigrum (7.15±0.75), S. halepense (7.13±0.69), B. ceiba (6.39±0.90), D. sissoo (5.74±0.56), E. camaldulensis (5.37±0.68), B. oleracea (5.13±0.00), Z. jujuba (4.43±0.30), S. officinarum (4.30±0.78), C. melo (4.00±0.11), S. munja (3.13±0.23) were recovered less frequently. Unknown plant parts (9.44±0.49) and unidentified material (5.60±0.39) appeared significantly. Other matters (3.81±0.48) were found to be less frequent. The analysis of fecal pellets showed the different percentage of food items consumed by porcupine (Fig-6). Z. mays (10.41%) and S. vulgaris (10.09%) were the most intensively consumed species in this season. P. juliflora (8.03%), M. azedarach (5.70%), C. dactylon (5.68%), M. alba (5.40%), M. indica (5.25%), P. guajava (4.92%), S. nigrum (4.44%), S. halepense (4.43%), B. ceiba (3.97%), D. sissoo (3.57%), E. camaldulensis (3.34%), B. oleracea (3.19%), Z. jujuba (2.75%), S. officinarum (2.67%), C. melo (2.43%), S. munja (1.95%) were recovered with different percentage. Unknown plant parts (5.87%), unidentified material (3.48%) and other matter (2.37%) were found in less percentage. In fecal pellets, stems (23.5%) were recovered in significantly high proportions followed by seed (29.2%), spike (17.3%), root (16.0%) and leaf (15.4%), while pod (4.4%) and tuber (4.0%) of different plant species appeared in low proportions.

48 c. Rakh Chobara Desert Lands: i. Spring: The analysis of the stomach contents of porcupine trapped during spring showed that 11 plants species were recovered. T. aestivum (26.59±2.75) was the most intensively consumed species. Tribulus terrestris (17.39±0.00), H. vulgare (14.00±1.10), P. juliflora (13.44±3.40), S. halepense (12.04±1.30) and C. rotundus (10.87±0.00) were recovered with high frequency. C. ciliaris (7.56±0.65), A. tenuifolius (5.96±1.38), Z. jujuba (5.84±1.43), V. mungo (4.55±0.00) and S. munja (4.31±0.53) were consumed in significant proportions. Unidentified (4.95±0.38) and unknown plant parts (9.39±0.72) were found less frequently. The percentage of food items of the analysis of the stomach contents of porcupine trapped during spring showed that Triticum aestivum (19.42%) was the most intensively consumed specie. T. terrestris (12.70%), H. vulgare (10.23%), P. juliflora (9.82%), S. halepense (8.80%), C. rotundus (7.94%), C. ciliaris (5.52%), A. tenuifolius (4.35%), Z. jujuba (4.27%), V. mungo (3.32%) and S. munja (3.15%) were also consumed. Unidentified (3.62%) and unknown plant fragments (6.86%) were found. Spike (31.0%) was consumed with higher percentage (Fig-11) followed by leaves (24.1%), stem (17.3%) seed (11.8%) and root (10.6%). Pods (5.0%) were also consumed in a significant proportion. It confirmed the result of Arshad et al., (1990). The fecal samples (n=15) were collected from the Rakh Chobara during the spring season. The analysis of the fecal pellets (Table-5) revealed that T. aestivum was consumed at highest mean relative frequency 28.07±1.86. C. ciliaris (14.52±1.97), D. sissoo (12.96±0.00), A. tenuifolius (12.83±1.26), C. dactylon (12.12±1.84), V. mungo (11.60±2.49), Cymbopogan jawarancusa (10.53±0.00) constituted the diet. S. halepense (9.09±0.00), P. juliflora (7.45±1.15), Z. jujuba (6.73±1.21), C. polygonoides (6.35±2.46). C. rotundus (5.98±0.91) and S. munja (3.60±0.82) were recorded in different frequency. Other matter (4.13±0.83) constituted the small part of the contents while the unknown plant (13.36±0.89) and unidentified (8.91±1.05) were found relatively in significant proportion. The analysis of the fecal pellets (Fig-10) revealed that T. aestivum was consumed at highest percentage (16.69%). C. ciliaris (8.63%), D. sissoo (7.70%), A. tenuifolius

49 (7.63%), C. dactylon (7.20%), V. mungo (6.90%), C. jawarancusa (6.26%), S. halepense (5.40%), P. juliflora (4.43%), Z. jujuba (4.00%), C. polygonoides (3.77%), C. rotundus (3.55%) and S. munja (2.14%) were recorded with different percentage. Other matter (2.45%) constituted the small part of contents while the unknown plant parts (7.94%) and unidentified (5.30%) were found relatively in higher percentage. Table 12 shows the consumption of the percentage of different parts of the plant species. Spike (27.2%), stem (18.9%), leaf (11.0%), pod (16.0%), tuber (8.2%) and seed (5.4%) appeared with different percentage. The presence of different plant species confirmed the result of Arshad et al. (1990). ii. Summer: All the samples collected in the summer season were taken in the month of May, June, July, August and September in 2009. During the summer season stomach contents of (n=5) animals were examined (Table-6). Analysis of the stomach contents of these specimens revealed that 9 types of food items of plant origin were consumed by the porcupine. Among these, S. vulgaris (30.79±1.87) was predominant, as it constituted larger percentage of total stomach contents. P. juliflora (25.09±2.28) and C. ciliaris (10.20±0.79) were the next most consumed items but were utilized relatively less intensively. Among other items eaten with decreasing frequency were C. polygonoides (8.74±1.36), C. melo (6.52±0.00), Z. jujuba (6.48±2.85), A. tenuifolius (5.89±0.63), T. terrestris (2.27±0.00) and C. dactylon (2.27±0.00). In the summer diet of the porcupine, unidentified plant food (5.34±1.20) and unknown plant parts (11.82±0.49) were less frequently constituent. The analysis of the stomach contents of porcupine trapped during summer showed percentage of food items. S. vulgaris (26.68%) was the most intensively consumed specie. P. juliflora (21.74%), C. ciliaris (8.84%), C. polygonoides (7.57%), C. melo (5.65%), Z. jujuba (5.61%), A. tenuifolius (5.10%), C. dactylon (1.97%) and T. terrestris (1.97%), unidentified (4.63%) and unknown plant parts (10.24%) were found with different percentage of the food items. Figure11 presents the summary of the food parts recovered from stomachs of porcupine. Seed (22.7%), stem (21.7%), spike (19.2%), leaf (17.0%) and root (16.7%) were recovered with higher percentage while pods (2.3%) with the less percentage.

50 The analysis of the fecal pellets showed that 13 types of food items of plant origin were consumed at different frequency by porcupines (Table-5) P. juliflora (21.05±1.54) was the most intensively consumed specie in this season. C. ciliaris (15.08±3.80), S. halepense (15.00±0.00), A. tenuifolius (12.89±1.15), C. dactylon (12.64±1.00), T. terrestris (11.36±3.76) appeared in high frequency.

Other matter (3.87±0.34) was found to be less frequent while unidentified (20.45±1.50) and unknown plants (16.21±0.68) were found to be highly significant. The analysis of fecal pellets showed the different percentage of food items by porcupine (Fig-10) P. juliflora (11.19%) was the most intensively consumed species in this season. , C. ciliaris (8.01%), S. halepense (7.97%), A. tenuifolius (6.85%), C. dactylon (6.72%), T. terrestris (6.04%), C. polygonoides (4.56%), S. munja (4.53%), A. procera (4.45%), D. sissoo (4.34%), C. jawarancusa (4.10%), Z. jujuba (4.09%), C. rotundus (3.40%), V. mungo (2.22%), other matter (2.06%), unidentified (10.87%) and unknown plants (8.61%) were found with different percentages. Figure 12 shows the consumption of the percentage of different parts of the plant species. Stem (20.2%), pod (18.2), root (17.0%), leaf (16.0%) and seed (11.3%) were found with high percentage while spike (8.8%) and tuber (8.1%) appeared with low percentage. iii. Fall: In the fall season the stomach content analysis showed that 9 types of food items of plant origin were consumed by the porcupines (Table-6). T. terrestris (30.17±5.98) was the most intensively consumed species in this season. P. juliflora (20.38±1.88) appeared in high frequency. S. halepense (13.66±2.82), C. polygonoides (13.27±2.86), A. tenuifolius (7.58±0.760), C. ciliaris (7.48±2.94), Z. jujuba (6.89±2.46), C. rotundus (5.31±1.14) and S. munja (4.55±0.00) contributed a significant proportion. Other matters (2.22±0.05) were found to be less frequent while unidentified (5.73±1.25) and unknown plants (9.21±1.34) were found significant proportions comparatively. In the fall season the stomach content analysis showed the percentage of the food items of plant origin were consumed by the porcupines (Fig-9). T. terrestris (23.86%) was

51 the most intensively consumed species in this season. P. juliflora (21.74%) appeared to be consumed in high percentage. S. halepense (10.80%), C. polygonoides (10.43%), A. tenuifolius (5.99%), C. ciliaris (5.92%), Z. jujuba (5.45%), C. rotundus (4.20%) and S. munja (3.60%) contributed different percentage. Other matters (1.76%) were found to be in less percentage while unidentified (4.53%) and unknown plant parts (7.28%) were found significantly. Figure11 present the summary of the food parts recovered from stomachs of porcupine. Leaf (27.0%), stem (25.1%), seed (22.0%) and root (15.1%) recovered with higher percentage while tuber (8.5%) and pod (2.1%) were in less percentage. The fecal samples of porcupines which were collected during fall season, showed predominance of T. terrestris (26.26±1.610) which remained the most intensively eaten food. P. juliflora (20.84±1.81), C. dactylon (12.48±1.33), C. ciliaris (10.96±1.81) were significantly consumed by the porcupine during the fall season. C. polygonoides (8.68±1.68), S. munja (8.29±1.58), S. halepense (6.67±0.00), A. tenuifolius (6.14±0.90), Z. jujuba (4.85±0.97), C. rotundus (4.17±1.89) were eaten much less intensively. Other matter (3.84±0.48) eaten less intensively and unidentified (10.16±1.32) and unknown plant (13.76±1.09) constituted the significant part of the total contents. The fecal samples showed the percentage of food items (Fig-10) with predominance of T. terrestris (19.15%). P. juliflora (15.20%), C. dactylon (9.10%), C. ciliaris (7.99%), C. polygonoides (6.33%), S. munja (6.05%), S. halepense (4.87%), A. tenuifolius (4.48%), Z. jujuba (3.54%), C. rotundus (3.04), other matter (2.80%), unidentified (7.41%) and unknown plant (10.04%) were in different percentage of the total fecal contents. Figure12 suggested that stem (25.6%) parts were representing in sufficient amount. Root (23.5%) and seed (20.7%) contributed significantly of the total fecal contents. Tuber (7.5%) and pod (2.4%) appeared with low frequency in fecal pellets. It confirms the finding of Roberts (1997) and Arshad et al., (1990). iv. Winter: Table 6 presents a summary of the relative frequency of food items recovered from stomachs of porcupines collected during winter. During this season 11 different plant species were recorded. Among these, T. aestivum (39.89±5.21) was predominant as it constituted most intensively eaten food. P. juliflora (18.28±1.55), H. vulgare (10.94±0.00)

52 and A. tenuifolius (10.91±0.00) appeared less commonly. Among less intensively consumed plants were S. halepense (8.59±2.34), C. ciliaris (8.40±1.13), C. rotundus (7.81±0.00), C. dactylon (7.14±0.00), C. polygonoides (6.74±1.71), Z. jujuba (4.76±0.00) and T. terrestris (4.76±0.00). Unidentified (5.09±0.93) and unknown plants (9.92±1.16) were consumed in low frequency. Mac Mahon (1985) observed the winter feeding habits of porcupine and he suggested that it consumed bark of different trees, including pines, fir and hemlock. Figure 9 presents a summary of the percentage of food items recovered from stomach of porcupines collected during winter. Among these, T. aestivum (27.85%) was predominant as it constituted most intensively eaten food. P. juliflora (12.76%), H. vulgare (7.64%), A. tenuifolius (7.62%), S. halepense (6.00%), C. ciliaris (5.86%), C. rotundus (5.45%), C. dactylon (4.38%), C. polygonoides (4.71%), Z. jujuba (3.32%), T. terrestris (3.32%), unidentified (3.55%) and unknown plant (6.93%) were consumed at different percentage. Stem (30.3%), spike (24.5%), leaf (18.5%) and seed (10.8%) were recovered with high frequency. Root (8.3%), tuber (4.1%) and pod (3.2%) were less frequently consumed. The study on the fecal pallets collected in winter season (Table-5) suggested that 12 types of food items of plant origin were recovered. T. aestivum (22.89±0.85), V. mungo (22.22±0.00) and T. terrestris (20.83±0.93) were eaten in sufficient amount, while A. procera (12.58±1.71), P. juliflora (12.21±1.10) were also recorded sufficiently. C. ciliaris (9.65±1.18), C. dactylon (8.68±0.70), Z. jujuba (6.20±0.62), C. polygonoides (5.88±0.58), S. munja (4.25±0.92), A. tenuifolius (4.17±0.54), C. jawarancusa (3.51±0.00) and C. rotundus (3.34±1.07) were less frequently recorded. Other matters (2.54±0.21), unidentified (6.94±0.91) and unknown plants (9.43±0.60) parts were less frequently recorded. The percentage of fecal pallet analysis of winter sample (Fig-10) showed different food items. T. aestivum (14.74%), V. mungo (14.31%) and T. terrestris (13.41%), A. procera (8.10%), P. juliflora (7.86%), C. ciliaris (6.21%), C. dactylon (5.59%), Z. jujuba (3.99%), C. polygonoides (3.79%), S. munja (2.74%), A. tenuifolius (2.68%), C. jawarancusa (2.26%), C. rotundus (2.15%), other matter (1.64%), unidentified (4.47%) and unknown plants (6.07%) were present in different percentages.

53 Analysis of fecal pellets (Fig-12) suggested that stem (34.7%) were representing in sufficient amount. Root (17.0%), seed (14.0%), leaf (11.1%) and spike (13.1%) contributed a significant part of total fecal contents. Tuber (7.4%) and pod (2.4%) appeared with low frequency in fecal pellets. It confirms the findings of Roberts (1997), Arshad et al. (1990) and Brooks et al. (1988).

Among these D. sissoo (17.51±2.66) was predominant as it was the major constituent. C. dactylon (15.31±2.96), C. ciliaris (14.73±1.54), T. terrestris (13.18±2.07), P. juliflora (12.88±3.89) and E. camaldulensis (10.76±1.01) appeared less commonly. The less intensively consumed plants were C. polygonoides (9.95±2.81), Z. jujuba (9.79±1.72), A. procera (8.36±2.97), S. munja (5.66±1.15), C. rotundus (5.40±0.31) and S. halepense (2.86±0.00). Other matters

62 (3.55±0.42), unidentified (7.65±0.63) and unknown plant parts (8.08±1.35) found in low frequency. Figure13 shows the percentage of food items of plant species as recovered in fall season. Among these D. sissoo (12.02%) was predominant with highest percentage. C. dactylon (10.51%), C. ciliaris (10.11%), T. terrestris (9.05%), P. juliflora (8.84%), E. camaldulensis (7.39%), C. polygonoides (6.83%), Z. jujuba (6.72%), A. procera (5.74%), S. munja (3.89%), C. rotundus (3.71%) and S. halepense (1.96%) were found in different percentages. Other matters (2.44%) were in low percentage while unidentified (5.25%) and unknown plant parts (5.55%) were also found. During fall, roots, stems, leaves, seeds, tuber and spike were consumed in different frequency. Seed (24.5%) was consumed with high frequency followed by stem (23.7%), leaf (20.9%), root (17.4%) and tuber (11.1%) and pod (2.1%). The study on the fecal pallet analysis of the fall season (Table-7) suggested that 12 types of food items of plant origin were eaten by porcupines. P. juliflora (17.59±1.39) and D. sissoo (17.22±1.95) were found in sufficient amount, while, T. terrestris (12.55±1.81), C. dactylon (11.68±1.29) and C. ciliaris (10.44±1.78) were also recorded sufficiently. A. procera (9.99±2.03), C. jawarancusa (8.57±0.00), C. polygonoides (8.42±1.37), S. munja (6.26±0.91), A. tenuifolius (4.88±0.00), Z. jujuba (4.73±0.77) and C. rotundus (4.44±0.00) were less frequent. Other matters (3.80±0.28) were present in much less frequency while unknown plant parts (15.46±1.28) were found in significant amount. The fecal pallet analysis of the fall season (Fig-14) suggested that P. juliflora (11.97%), D. sissoo (11.72%), T. terrestris (8.54%), C. dactylon (7.95%), C. ciliaris (7.11%), A. procera (6.80%), C. jawarancusa (5.83%), C. polygonoides (5.73%), S. munja (4.26%), A. tenuifolius (3.32%), Z. jujuba (3.22%) and C. rotundus (3.02%) were found in varied percentages. Other matters (2.59%) were present in less percentage while unknown plant parts (10.52%) were found at high percentage. In fecal pellets, seed (22.6%) were recovered in significantly high proportion followed by stem (28.4%), leaf (23.1%), root (21.2%) and seed (18.4%) while pods (6.3%) and tubers (2.4%) of the different plant species appeared at low frequency.

63 iv. Winter: Table-8 presents a summary of the relative frequency of food items recovered from stomachs of porcupines collected during the winter. During this season 14 different plant species were recorded. Among these, T. aestivum (13.88±1.00), S. munja (13.75±0.00) and D. sissoo (13.33±1.84) were predominant. T. terrestris (12.93±1.65) and C. dactylon (10.76±0.91) appeared less commonly. Among the less intensively consumed plants were P. juliflora (9.89±0.49), H. vulgare (9.40±0.00), A. tenuifolius (7.06±0.76), A. procera (6.28±0.54), S. halepense (5.66±0.00), E. camaldulensis (5.21±1.21), C. polygonoides (3.41±1.43), Z. jujuba (2.95±0.72) and C. jawarancusa (2.56±0.00). Unidentified food items (9.92±1.13) and unknown plant parts (6.33±0.94) contributed significantly of the total contents. Fig-13 presents a summary of the percentage of food items recovered from stomachs of porcupines collected during the winter. Among these, T. aestivum (10.41%), S. munja (10.31%) and D. sissoo (10.00%), T. terrestris (9.70%), C. dactylon (8.07%), P. juliflora (7.42%), H. vulgare (7.05%), A. tenuifolius (5.30%), A. procera (4.71%), S. halepense (4.25%), E. camaldulensis (3.91%), C. polygonoides (2.56%), Z. jujuba (2.21%) and C. jawarancusa (1.92%) were identified. Unidentified food items (7.44%) and unknown plant parts (4.75%) contributed to the total contents. Fig-15 shows the consumption percentage of different food parts like stem, leaf, seed, spike and pod recovered from the stomach of porcupines collected during winter seasons. Stem (34.1%), leaf (30.0%) and root (13.5%) were consumed with a high frequency while spike (9.3%) and pod (4.3%) with less frequently. The study on the fecal pallet analysis of the winter samples (Table-7) suggested that 14 types of plant origin were eaten by porcupines. A. procera (16.58±3.18) and D. sissoo (16.66±0.91) were in sufficient amount while T. aestivum (11.65±1.47) and P. juliflora (10.04±1.19) were also recorded sufficiently. C. ciliaris (9.45±0.89), T. terrestris (8.95±1.39), Z. jujuba (8.38±1.05), C. dactylon (8.19±1.01), S. halepense (8.04±1.16), C. polygonoides (7.91±0.69), S. munja (3.61±0.39), V. mungo (3.23±0.00), C. rotundus (3.12±0.30) and A. tenuifolius (2.63±0.50) were less frequently recorded. Other matters (3.73±0.38) were also less frequently recorded. Unidentified (8.85±0.72) and unknown plant parts (15.72±1.30) contributed significantly of the total contents.

64 The fecal pallet analysis of the winter sample (Fig-13) suggested that A. procera (11.30%), D. sissoo (11.35%), T. aestivum (7.94%), P. juliflora (6.84%), C. ciliaris (6.44%), T. terrestris (6.10%), Z. jujuba (5.71%), C. dactylon (5.58%), S. halepense (5.48%), C. polygonoides (5.39%), S. munja (2.46%), V. mungo (2.20%), C. rotundus (2.13%) and A. tenuifolius (1.79%) were found in different percentages. Other matters (2.54%), unidentified (6.03%) and unknown plant parts (10.71%) contributed significantly to the percentage of the total contents. Analysis of fecal pellets (Table16) suggested that stem (32.7%) were represented in sufficient amount. Spike (22.8%), root (17.5%) and seed (10.9%) contributed significant part of total fecal contents. leaf (8.12%) and pod (2.0%) appeared with low frequency in fecal pellets. It confirms the finding of Roberts (1997), Arshad et al. (1990) and Brooks et al. (1988).

81 f. Shorkot Plantation: i. Spring: The analysis of the stomach contents of porcupines trapped during the spring showed that 12 plant species were consumed. E. camaldulensis (18.63±4.63) was the most intensively consumed species. S. halepense (16.29±0.97), P. juliflora (13.21±0.00), T. aestivum (13.19±0.00) and M. alba (10.72±1.45) were recovered with high frequency. B. ceiba (9.88±2.59), M. azedarach (8.74±1.38), D. sissoo (7.81±2.32), L. aphaca (7.20±2.45), Z. jujuba (6.96±1.34), S. munja (3.80±0.00) and C. rotundus (2.96±0.35) were also consumed in significant proportions. Unidentified (4.04±0.53) and unknown plant parts (9.86±1.48) were also found in significant proportion. The analysis of the stomach contents showed the percentage of the food items (Fig- 21) the E. camaldulensis (13.98%) was the most intensively consumed species. S. halepense (12.22%), P. juliflora (9.91%), T. aestivum (9.90%), M. alba (8.04%), B. ceiba (7.41%), M. azedarach (6.56%), D. sissoo (5.86%), L. aphaca (5.40%), Z. jujuba (5.22%), S. munja (2.85%) and C. rotundus (2.22%) were consumed in different percentages. Unidentified (3.03%) and unknown plant parts (7.40) were also found. Consumption of eucalyptus species confirms the observation of Khan et al., (2000), Idris and Rana, (2001). Leaves (28.5%) were consumed with higher percentage (Fig-23) while spike (21.5%), stem (18.6%) and seed (17.4%). Root (8.0%), pod (3.0%) and tuber (2.8%) were also consumed in a significant proportion. The analysis of fecal pellets collected during the spring season (Table11) suggested that M. azedarach (31.22±4.07) was consumed in highest frequency. B. ceiba (14.61±4.49), T. aestivum (14.36±0.97), C. dactylon (13.22±0.82), M. alba (11.59±4.43), E. camaldulensis (10.81±1.00) and P. juliflora (10.74±1.63) contributed significant proportions.

Other contents (1.63±0.17) were present in the lower order, while unidentified (5.27±0.33) and unknown plants (9.72±0.71) were also found. The analysis of the fecal pallets collected during this season (Fig.26) suggested that D. sissoo (11.93%) was consumed with the highest percentage. T. aestivum (8.72%), S. vulgaris (7.91%), C. dactylon (7.26%), M. alba (6.76%), B. ceiba (6.58%), P. juliflora (6.75%), E. camaldulensis (5.98%), M. azedarach (5.59%), Z. jujuba (4.59%), L. aphaca (3.37%), C. annulatum (3.34%), B. campestris (3.33%), C. melo (2.16%), C. rotundus (2.06%) and A. cepa (2.06%) were found in different percentage. Other contents (1.16%) were present in much less percentage while unidentified (3.74%) and unknown plant (6.89%) were found in less percentage. Analysis of fecal pellets (Fig.28) suggested that stem parts (37.9%) were represented in sufficient amount. Spike (15.3%), leaf (14.5%) and root (12.4%) contributed significant part of total fecal contents. Seed (9.6%), tuber (7.6%) and pod (2.4%) appeared in low frequency in fecal pellets. It confirms the finding of Roberts (1997), Arshad et al. (1990) and Brooks et al. (1988).

The analysis of stomach contents of these specimens revealed 9 types of food items of plant origin were consumed by porcupines. A. modesta (24.21±1.39) and S. vulgaris (23.38±0.00) were the most consumed species. C. dactylon (15.68±5.27), P. juliflora (14.26±8.89) and Z. jujuba (10.05±1.27) were recovered at high frequency. D. viscose (9.63±0.54) and D. annulatum (7.48±0.99) were consumed in significant proportions. Other matters (2.44±0.00) were in low frequency. Unidentified (5.62±0.59) and unknown plants (10.17±2.33) formed significant proportion of the stomach contents. During the summer season stomach contents showed the percentage of food items (Fig.29) as A. modesta (19.70%), S. vulgaris (19.02%) were the most consumed species. C. dactylon (12.16%), P. juliflora (11.60%), Z. jujuba (8.18%), D. viscose (7.83%) and D. annulatum (6.09%) were consumed in different percentage. Other matters (1.19%) were in low percentage. Unidentified (4.57%) and unknown plants (8.27%) found with significant percentage of the stomach contents. The analysis of plant parts during the summer season showed (Fig.31) that stem (31.6%) appeared with higher frequency, followed by leaf (19.5%), seed (17.1%) and root (15.7%) of different plants while spike (7.3%), pod (4.2%), flower (2.3) and tuber (2.1%) were less frequently found. The analysis (n=15) of the fecal pellets collected from Kalar Kahar showed the plant tissues belonging to 10 species in this season (Table15). Among these, A. modesta (27.57±2.16) was extensively consumed plant species. Z. mays (21.63±2.28), S. vulgaris (21.35±4.31), C. dactylon (16.73±1.68) and P. juliflora (10.67±2.93) were recovered at high frequency. C. annum (9.68±0.00), Z. jujuba (8.78±1.35), D. annulatum (7.32±1.15) and D. viscose (6.22±1.03) were in low frequency. Other matters (2.03±0.41) found were very small part of total stomach contents while unidentified (5.99±0.66) and unknown plants (11.27±1.84) were found in significant proportion. The percentage of the food items recovered from fecal pellets (Fig.30) were: A. modesta (18.47%) was extensively consumed plant species while Z. mays (14.49%), S. vulgaris (14.31%), C. dactylon (11.21%), P. juliflora (7.15%), C. annum (6.49%), Z.

104 jujuba (5.88%), D. annulatum (4.90%) and D. viscose (4.17%) were found in different percentages. Other matters (1.36%) were present in small amount while unidentified (4.01%) and unknown plants (7.55%) were also found. The analysis of plant parts during the summer season showed (Fig.32) that stem (25.8%) appeared with higher frequency followed by seed (18.2%), leaf (16.9%), spike (14.2%), root (12.5%) and pod (10.1%) while tuber (2.1%) was less frequent. This confirm the report of Bibi (2004). ii. Spring: In the spring season the stomach contents analysis showed that 7 types of food items of plant origin were consumed by porcupines (Tab.16). Among these T. aestivum (37.17±1.70) was the most intensively consumed species. A. modesta (19.91±2.21) was recovered with high frequency. C. dactylon (8.33±1.63), H. vulgare (6.12±1.09), Z. jujuba (5.34±1.80), P. juliflora (4.68±0.73) and D. viscose (3.24±0.88) were consumed in significant proportions. Other matter (1.64±0.16) formed very small part of the total contents while unidentified (9.53±1.45) and unknown plants (10.41±2.31) were consumed in significant proportion. In the spring season the stomach contents analysis showed the percentage of the food items, (Fig.29) among these T. aestivum (34.94%) was the most intensively consumed specie. A. modesta (18.72%), C. dactylon (7.83%), H. vulgare (5.75%), Z. jujuba (5.02%), P. juliflora (4.40%) and D. viscose (3.05%) were consumed with different percentages. Other matter (1.54%) constituted very small part of the total contents while unidentified (8.96%) and unknown plants (9.79%) were consumed in significant percentages. Stems (26.6%) were consumed with higher percentage (Fig.31) while leaf (23.2%), spike (22.7%) and root (10.4%). Seed (5.5%), flower (4.5%), pod (3.6%) and tuber (3.2%) were also consumed in a significant proportion. The fecal samples (n=15) of porcupine which were collected during the spring season, showed (Fig.15) predominance of T. aestivum (38.61±3.02) which was consumed at the highest frequency. A. modesta (21.16±3.11) and C. dactylon (11.36±2.42) constituted sufficient proportions. H. vulgare (7.43±1.87), D. viscose (5.86±1.07), Z. jujuba (5.48±1.24) and P. juliflora (5.05±1.14) recorded with different frequency. Other

105 matters (2.37±0.32) constituted the small part of the contents while unidentified (10.79±1.12) and unknown plants (11.56±1.07) were found in high frequency. The fecal percentage of the food items (Fig.30) showed predominance of T. aestivum (32.26%) which was consumed at the highest percentage. A. modesta (11.68%), C. dactylon (9.49%), H. vulgare (6.21%), D. viscose (4.90%), Z. jujuba (4.58%) and P. juliflora (4.22%) recorded with different percentages. Other matters (1.98%) constituted the small proportion of the total contents while unidentified (9.02%) and unknown plant (9.66%) were found in high percentage. Figure 32 shows the consumption of the percentage of different parts of the plant species. Stem (33.6%), spike (19.4%), root (16.3%) and leaf (12.2%) appeared with higher frequency while seed (9.3%), pod (5.4%) and tuber (3.5%) were found less frequently. iii. Fall: The specimens (n=4) were captured in the months of September, October and November. Plant tissues belonging to 8 species were recovered from porcupine stomachs in this season (Tab.16). A. modesta (31.78±2.56) was the most intensively consumed species. P. juliflora (19.85±3.08) and C. dactylon (13.29±0.87) were recovered at higher frequency. D. viscose (6.39±2.49), H. vulgare (4.65±1.87), S. vulgaris (4.35±0.00), C. rotundus (4.17±0.17) and Z. jujuba (3.91±0.98) were consumed in significant proportions. Unidentified (6.79±1.66) and unknown plant (13.48±1.65) formed significant part of stomach contents. A. modesta has been reported to be consumed by the porcupines (Taber et al., 1967; Chaudhary and Ahmad, 1975; Khan et al., 2000). The specimens showed the percentage of the food items (Fig.29) among these A. modesta (29.25%) was the most intensively consumed species. P. juliflora (18.27%), C. dactylon (12.23%), D. viscose (5.88%), H. vulgare (4.28%), S. vulgaris (4.00%), C. rotundus (3.84%) and Z. jujuba (3.60%) were consumed in different percentages. Unidentified (6.25%) and unknown plants (12.41%) were present in significant percentages. Figure 31 shows the consumption of the percentage of different parts of the plant species. Stem (28.1%), root (19.1%), seed (16.1%), leaf (14.9%) and spike (10.8%) appeared with higher frequency while pod (6.5%) and tuber (4.3%) were found less frequently.

106 The fecal samples (n=15) of porcupines, showed predominance of A. modesta (23.90±1.03) which remained the most intensively eaten food. Z. mays (18.64±0.00), S. vulgaris (17.80±2.15), C. dactylon (16.59±0.85) and P. juliflora (11.34±1.34) appeared in high frequency. Z. jujuba (8.27±1.92), H. vulgare (7.21±0.48) and D. viscose (4.52±0.96) were found to be less frequent. Other matters (4.35±0.09) were found to be less frequent while unidentified (8.52±1.05) and unknown plants (12.85±0.86) were found to be highly significant. The consumption of Z. mays crop confirm the observations of Geddes and Iles (1991) that porcupines cause extensive damage to maize crop in the northern areas of Azad Kashmir, Potohwar plateau, Z. mays crops consumption also support the observation of Ahmed et al. (1987) who reported that porcupine damage in maize fields in Faisalabad district was widespread. The percentage of food items of the fecal parts showed (Fig.30) that A. modesta (17.84%) remained the most intensively eaten food. Z. mays (13.91%), S. vulgaris (13.28%), C. dactylon (12.38%), P. juliflora (8.46%), Z. jujuba (6.17%), H. vulgare (5.38%) and D. viscose (3.37%) were found in different percentages. Other matters (3.25%) were found in less percentage while unidentified (6.36%) and unknown plants (9.59%) were found relatively with high percentage. Analysis of plant parts during the fall season showed (Fig.32) that stem (30.2%) appeared with higher frequency, seed (19.1%), spike (18.3%), root (12.0%) and leaf (11.0%) of different plants were also present in sufficient amount while pod (6.6%) and tuber (2.6%) were less frequent. iv. Winter: The analysis of the winter sample of the stomach contents (n=5) revealed that 8 plant species were consumed by the porcupines. Among these, A. modesta (29.68±1.14) was predominantly consumed plant specie, as it constituted a large percentage of the total stomach contents. C. dactylon (24.12±2.88) and T. aestivum (11.84±0.00) were found to be highly frequent. Z. jujuba (9.50±2.96), P. juliflora (6.58±0.00), D. viscose (5.56±1.02), D. annulatum (3.95±1.32) and H. vulgare (3.51±0.00) were utilized less frequently. Other matter (1.97±0.66) was less frequent. Unidentified (8.04±0.64) and unknown plant (10.53±0.76) were found frequently. A. modesta has been reported to be damaged by the porcupine (Taber et al., 1967; Chaudhary and Ahmad, 1975; Khan et al., 2000).

107 Analysis of the winter sample of the stomach contents showed the percentage of the food items (Fig-29) among these, A. modesta (25.75%) was predominantly consumed plant species, as it constituted a large percentage of the total stomach contents. C. dactylon (20.92%), T. aestivum (10.27%), Z. jujuba (8.24%), P. juliflora (5.71%), D. viscose (4.82%), D. annulatum (3.43%) and H. vulgare (3.04%) were utilized in different percentages. Other matter (1.71%) was used in less percentage. Unidentified (6.97%) and unknown plants (9.13%) were found in significant proportion. Stem (35.8%), leaf (20.9%), root (19.4%) and spike (10.4%) were recovered with high frequency. Seed (6.7%), pod (5.9%) and flower (1.1%) were less frequent. The fecal samples (n=15) were collected from the study area during the winter season. The analysis of the fecal pellets (Table15) revealed that A. modesta (30.14±2.22) was consumed at highest frequency. C. dactylon (19.40±1.43) and T. aestivum (17.23±2.52) constituted sufficient proportion of the diet. Z. jujuba (7.86±0.84), D. viscose 5.69±0.64), S. vulgaris (5.26±0.00), P. juliflora (5.14±0.57), D. annulatum (4.87±1.43) and H. vulgare (3.51±0.00) were recorded with different frequency. Other matters (2.42±0.61) constituted a small portion of the contents while unidentified (7.92±1.01) and unknown plant (10.81±1.72) were found to be less frequent. A. modesta has been reported to be consumed by the porcupine (Taber et al., 1967; Chaudhary and Ahmad, 1975; Khan et al., 2000). The fecal samples (n=15) were collected from the study area during the winter season. The percentage of food items of the fecal pellets (Fig-30) revealed that A. modesta (25.06%) was consumed at the highest percentage. C. dactylon (16.13%), T. aestivum (14.33%), Z. jujuba (6.54%), D. viscose (4.73%), S. vulgaris (4.37%), P. juliflora (4.27%), D. annulatum (4.05%) and H. vulgare (2.92%) were recorded with different percentages. Other matter (2.01%) constituted a small portion of the total contents while unidentified (6.59%) and unknown plant parts (8.99%) were also found. The analysis of plant parts during the winter season showed (Fig.32) that stem (42.1%) appeared with higher frequency, followed by root (17.0%), leaf (14.6%) and spike (10.4%) of different plants while pod (6.3%) and tuber (2.2%) were less frequent.

Fecal Stomach Group

Figure 35: The Comparison of the Relative Frequency of Stomach contents and Fecal Pallets.

116 Between the fecal pellets and stomach contents, the fecal (4.3) relative frequency was more than stomach (2.37) as shown in figure 35. This was due to limited degree of trapping for obtaining the stomach contents because porcupines are very cautious, human shy and basically nocturnal, making its direct studies on feeding behavior difficult. This difference confirm the findings of Roberts (1997), Bibi (2004) and Bibi et al. (2006). Relative Frequency among Food Items:

Relative frequency among the food items were A. modesta (8.78), A. hypogea (1.90), C. polygonoides (4.54), D. annulatum (0.28), D. viscose (1.69) and L. aphaca (0.57) were found only in one location. A. tenuifolius (3.416), M. sativa (0.42), S. tuberosum (0.10), C. ciliaris (5.419), B. campestris (1.570), P. sativum (0.21), C. jawarancusa (0.46) and T. terrestris (5.02) were found in two locations. A. procera (3.00), C. annum (0.21), S. melongena (0.63), V. mungo (1.04), P. guajava (0.71), L.esculentum (0.38) and C. maxima (0.16) were found in three locations. B. oleracea (0.96), A. cepa (0.823), M. indica (1.35), M. indica (0.34) and S. munja (1.15) were found in four locations. S. officinarum (0.69), B. ceiba (4.11), S. nigrum (0.98), M. azedarach (4.16) and M. alba (3.98) were found in five locations. H. vulgare (1.69), Z. mays (6.37) and E. camaldulensis (6.12) were found in six locations. D. sissoo (6.39), S. halepense (3.83), D. bipinnata (0.54) and C. melo (0.68) were found in seven locations. S. vulgaris (6.54), T. aestivum (8.56), C. dactylon (7.84), C. rotundus (1.58), Z. jujuba (2.70), P. juliflora (9.85), unidentified (7.944), unknown plant parts (11.12) and other (1.38) were found in eight locations. Relative Frequency of Fecal pellets With Respect to Seasons:

122 highest in winter (3.72) and lowest in summer (2.57)., other matter, unidentified and unknown plants were also present in the four seasons. Analysis of the All Variables: The table 17 shows the different locations had significant effect on distribution of food items. The four seasons did not differ statically so for as distribution of food items were concerned. Similar groups (Fecal and Stomach) as well as food items contributed significantly (P<0.05) H. indica is basically herbivorous, and about 99% of its total diet consists of material derived from plant source. Only some stomach contents exhibited the presence of quill, thread and hair. The overall picture of analysis of stomach contents of H. indica suggested that species largely depends upon different parts of prevalent vegetation. A marked shift in the intake of different materials during different seasons and areas can largely be attributed to the availability of food species or parts of the plant. This study confirms the observation of Amjad et al. (2009); Mian et al. (2007) Inayatullah (2006); Pervez. (2005); Bibi, (2004); Khan et al. (2000); Roberts (1997); Ahmad et al. (1987) and Chaudhary (1970). Table 17: Analysis of Variance of Different Parameters

Fig-41 Classification Tree of Comparison Fecal and Stomach Contents. Figure 41 shows classification tree of fecal and stomach contents. Node shows the fecal pellet particles 10988 i.e 66.5% of the total particles analyzed. Node 2 shows the stomach content particles 5544 i.e. 33.5% of the total particles analyzed. The comparison of the results of the stomach content analysis and those derived from the fecal pellet study suggested that the two modes of study are significantly different from one another. No previous study is available on comparison of two routes of study in porcupine. The fecal pellets are more easily available and may be used reliably, as it provides a larger sample. In porcupine the stomach contents provide large pieces of the food consumed, which can be identified microscopically by comparison with reference materials. Thus the stomach contents studies on food and feeding are more reliable, while the fecal pellet studies are though, indirect can be conducted on a larger sample, easier to collect. The analysis of the stomach contents and fecal pellet samples collected during different seasons and geographical locations suggested some degree of variation in composition and prevalence of food species. This is expected under the seasonal and geographical variation in the prevalence of different plant species in different localities and during different seasons, keeping to the available physic-biotic conditions.

126 Diversity in Diet of Hystrix indica in Irrigated Forest Habitat:

Berger-Parker index was calculated for stomach samples of porcupine which showed the diversity of diet in four seasons. In order to ensure the variation in diet, diversity index was calculated from Berger-Parker equation. Berger-Parker index of fall and winter were almost similar i.e. 5.68 and 5.94 while summer had lowest values i.e. 4.85 which showed the less diversity (Tab-18). It showed that porcupine tended to have more diversity during spring seasons (6.38). Therefore porcupine consumed 17 different plant species during spring season, indicating more diversity than other seasons. Table 19 shows the analysis of fecal pellets of porcupine collected during the four seasons. The Berger-Parker index (d) of each season was calculated by the dominance of species according to the habitat. Berger-Parker index of winter and fall were almost similar i.e. 5.60 and 5.66 while spring was also 5.25. It showed that the diet of porcupine during summer was more diverse. Therefore, porcupines consumed 18 different plant species during summer season, which had more diversity as compared to other seasons. It confirms the findings of Inayatullah (2006).

127 Diversity in Diet of Hystrix indica in Irrigated Sandy Habitat:

Thal represents sandy desert ecosystem of Punjab. Annual precipitation in these areas is less than 75 mm and natural vegetation is scarce. Water table is generally very low. Rakh Gouharwala and Rakh Chobara were selected for the desert ecosystem. Berger-Parker index was calculated for the stomach samples of porcupines which showed the diversity of diet in the four seasons. In order to ensure the variation in diet, diversity index was calculated from Berger-Parker equation. Berger-Parker index of spring and fall were almost similar i.e. 5.95 and 5.83 while winter had lowest values i.e. 3.68 which showed less diversity in diet (Tab-20). It showed that porcupines tend to have more diverse diet during fall and spring seasons. Therefore, porcupine consumed 16 different plant species during spring season, which were more diverse than other seasons. In table 21 the analysis of fecal pellets of porcupines collected during the four seasons is presented. The Berger-Parker index (d) of each season was calculated by the species dominance according to habitat of porcupines. Berger-Parker index of fall and spring were almost similar i.e. 3.93 and 3.74 while summer was 4.05. It showed that porcupine tended to have more diversity during the winter 5.30. Therefore, porcupines consumed 17 different plant species during winter season, which were more diverse than other seasons.

128 Diversity in Diet Hystrix indica in Agriculture Lands Habitat:

Faisalabad and Qaidabad were selected for the agriculture lands. Berger-Parker index was calculated for stomach samples of porcupines which showed the diversity of diet in the four seasons. In order to ensure the variation in diet, diversity index was calculated from Berger-Parker equation. Berger-Parker index of spring was lowest in diversity 3.94 while summer had second lowest 4.64 (Tab-22). Berger-Parker index showed that porcupines tend to have more diverse diet during winter season (6.38). Therefore, porcupines consumed 18 different plant species during winter season, which were more diverse than other seasons. The table 23 shows the analysis of fecal pellets collected during the four seasons. The Berger-Parker index (d) of each season was calculated by the species dominance according to their habitats. Berger-Parker index of winter and summer were almost similar i.e. 4.24 and 4.48. The spring season had lowest values i.e. 3.46 while it was highest value of fall season 5.37. It showed that porcupines tend to have more diverse diet during fall. Therefore, porcupines consumed 15 different plant species during summer season, which were more diversed than other seasons. It confirms the findings of Inayatullah (2006).

129 Diversity in Diet of Hystrix indica in Link Canal Habitat:

The canal irrigation extends in some areas, where irrigated agriculture is exercised, there are sufficiently large tracts under wild undulating sand dunes, even in the extensively irrigated/ arable tracts, which provide denning habitat for the porcupines. The embankments along the canals also provide favourite denning sites for the porcupines. The seepage water from the adjacent canals causes the problem of water logging and creation of small water bodies in certain tracts. Qadirabad Ballokey canal was selected for the link canal eco-system. In order to ensure the variation in diet, diversity index was calculated from Berger- Parker equation. Berger-Parker index of spring and fall (Tab. 24) were almost similar i.e. 4.67 and 4.28. Summer diversity was 6.04 while winter (8.71) showed maximum diversity. Therefore, porcupines consumed 20 different plant species during winter season, which were more diverse than other seasons. In table 25 the fecal pellets of porcupines collected during four seasons were subjected to analysis. The Berger-Parker index (d) of each season was calculated by the species dominance according to occurrence of species. Berger-Parker index of spring, winter and summer were almost similar i.e. 4.57, 4.47 and 4.27, respectively. In fall season highest value was 5.12. It showed that porcupines tend to have more diversity during the fall diet. Therefore, porcupine consumed 14 different plant species during fall season, which were more diversed than other seasons.

130 Diversity in Diet of Hystrix Indica in Rainfed Pothohar Belt Habitat:

Berger-Parker index was calculated for stomach samples of porcupine which showed the diversity of diet in four seasons. In order to ensure the variation in diet, diversity index was calculated from Berger-Parker equation. Berger-Parker index of winter and summer were almost similar i.e. 2.69 and 2.37 while spring had lowest value i.e. 1.59 which showed the low diversity (Tab-26). It showed that porcupines tend to have more diverse diet during fall season (3.69). Therefore, porcupines consumed 6 different plant species during fall season, which were more diverse than other seasons. In table 27 the results of analysis of fecal pellets of porcupine collected during the four seasons are presented. The Berger-Parker index (d) of each season was calculated by the species dominance according to occurrence of species. Berger-Parker index of summer and fall were almost similar i.e. 3.30 and 3.23 while winter was also i.e. 2.62. Spring had lowest value i.e. 1.62 which showed the low diversity. Therefore, porcupine consumed 7 different plant species during summer and fall seasons, which were more diversed than other seasons.

131 Nature and Extent of the Porcupine Damage to Different Trees and Cultivated Crops:

A. Crops: i. Wheat: The collected data revealed that porcupine damage was observed in 41 fields of wheat crop out of 105 fields in growing areas of Punjab. The damage was 4.58±1.14 % in Faisalabad, 6.82±2.03 % in Quaidaabad and 5.88±1.53 % in Sheikhupura. The previous estimates on wheat damage in Pothowar belt was 8.50±0.96% (Mia et al., 2007). This appeared a heavy damage, but it was quite as expected from such a large rodent. Porcupine is herbivorous in diet. The natural vegetation in the area is limited during the winter while at the same time the wheat is available in the fields to be damaged by porcupine. The damage was usually confined to the boundaries of the fields rather deep into the wheat fields. However, the degree of damage to crops in Punjab is non-significant (F-value=3.97, P<0.05). ii. Groundnut: Groundnut (A. hypogea) is one of the major oilseed crops grown in Pakistan. The nuts are not used generally for oil extraction but are consumed locally in fresh or roasted form. These are also added to sweets and biscuits to make them more delicious and nutritious. The damaged data collected from Quaidaabad showed relatively higher damage (4.82±2.07%). However, it varied from 3.19% to 11.92%. Relatively higher damage was expected from the porcupine; because the species has an extensive digging habit moreover groundnut is relished by the rodents and provides a rich source of energy for the animal. A high damage to groundnut, 30-40 plants per night was also reported by Brooks et al. (1988) whereas Mia et al. (2007) estimated groundnut damage (20.2±7.2%) caused by porcupine in Chakwal. Damaging and killing of groundnut plants was made by porcupines through digging out the nuts from roots in the ground (Plate 8). The damage was observed into the soil up to 2.5 to 7.25 cm. The clawed area generally resembles loose soil under the plant. Intact partially consumed and empty groundnut shells were found scattered in the clawed area. The attack was found confined to plants present in the corner of a field. Footprints of the animal or burrow opening confirmed its presence in the surrounding area.

132 iii. Onion: The porcupine damaged onions in Bhakhar (Table 28) which was relatively low damage 2.72±1.15%. The major part of the damage was inflicted when the onion crop was still very young, whereas the ripe and marketable onions faced considerably less damage (1.82±1.15%). Mian et al. (2007) studied the onion damage in Bhakhar, during 2004. The estimated range of damage was reported as 0.9%to 5.4%. Low damage inflicted to onions is hard to be explained, except for a lower preference of the species due to its taste/smell. It has been observed that porcupines did not attack the green foliage of the onion crop, which remain above the ground. This part remained unconsumed even when the plants were uprooted by the rodent (Plate 7). iv. Maize: Maize is the third most important cereal crop grown in Pakistan. A part of the maize production is used as animal fodder and the remainder is for human consumption. In the Punjab the crop is mainly planted during the mid-monsoon rains and harvested in October and late November. It is one of the few crops that can be grown in the irrigated areas during this period and still leave ample time for wheat crop cultivation. During the survey, a total number of 60 maize fields were visited. Porcupine infestations were noted in 37 fields. In Faisalabad the damage range of maize was 6.37 ±2.77%, 16 fields out 30 were damaged. In Sheikhupura the damage was 5.51±2.68%, 21 fields out of 30 were infested by porcupine. Khan et al. (1997) estimated 10.7% porcupine damage in Azad Jammu and Kashmir. Earlier to this Ahmad et al. (1987) recored 0.83% damage in central Punjab. In this study only few fields were sampled in Faisalabad district. During this survey porcupine damage pattern was also noted. Porcupine (Hystrix indica) could not reach the cobs because of their small size. So first, they cut the stem from the base and when the plant was in the reach of animals, they will eat the cobs. v. Melon: The porcupine inflicted a comparatively heavier damage to melon fruits, whereas the vegetative part of the plants was not damaged. Data revealed that 4.44±3.39% of the ripe melons were partially damaged by the porcupines in Bhakhar. Earlier to this no damage data was collected.

133 vi. Sugarcane: Very little information on damage by porcupine to sugarcane was published. A total of 60 fields were visited and 12 fields were found damaged. In Faisalabad the damage (4.65± 2.28%) was observed in five fields. In Sheikhupura the damage (5.51±2.68%) was found in 7 fields. The damage pattern in sugarcane showed that porcupine first attacked on the roots of the crops and then they damaged the stem of the crop. The damage extended into the soil about 2.5 to 7.5 cm. The clawed area generally resembled loose soil under the plant. The attack usually was restricted to the center of a field. Positive proof of porcupine presence was the presence of the footprints of the animal or burrow opening in the area. vii. Cotton: No damage was observed in the cotton crop. viii. Vegetables/Fruits: On the basis of information collected through the farmers, the porcupine inflicted significant damage to cauliflower, cabbage, potato seed, orange and mango fruit (picked from lower branches), roots of pepper, sorghum, turnip, radish, carrot and okara (lady finger). The porcupine has also been reported to cause damage to millet, barley, clover, mustard, gram, lucerine, mongi, pea flower, potato, radish, rice, sweet potato, sunflower and tara mera. Khan et al. (2000) reported 17.56% porcupine damage to potatoes near Attack, Punjab while Pervez (2006) reported 2.20% damage to potatoes and 4-36% damage to sweet potatoes in Balochistan. Damage to cabbage, pea and carrot was estimated at 1-4% in different areas of Balochistan. According to Mia et al. (2007) damage decreased with increase in distance of the cultivated field from the nearby burrow opening of the rodent, and little damage was caused in the field located beyond 5 km of the hills or burrowing habitat (Roberts, 1997). The same observation was reported in the studies of Saltz (1985) and Sever and Mendelsohn (1991). They concluded that the nocturnal course of porcupine in desert averaged to 5.5 km. B. Forest Plantations i. Nursery/stocking damage The damage to the nursery plantation of Shisham (D. sissoo) (Table 29) was around 11.00±2.93% in Rakh Gouharwala and 8.63±2.45% in Daphar plantations .Data collected on the Simal (B. ceiba) nursery in Daphar plantations revealed a very heavy damage

134 (58.4±4.00%) to the nursery plantation (Plate. 5). In Rakh Gouharwala the damage to A. porcera was 8.36±2.19% and 5.22±2.28% in Rakh Chobara. It appeared that both A. porcera and D. sissoo were equally susceptible to the porcupine damage. Heavy damage in Bombax ceiba stock and the reported variation in the damage can be mainly attributed to the age of nursery plantation. According to Mia et al. (2007), porcupine attack starts with the development of the woody stem in the plantation. The younger plantations do not attract the porcupine, while the older trees, with fleshy roots and woody stem, are more vulnerable to the damage. Earlier to this, Ahmad and Chaudhry (1977) reported that in a 4 ha, six months old D. sissoo nursery at Kundian, only 25% plants escaped porcupine damage while the rest were found clipped and thrown on the ground. They also observed that porcupine damage has become a limiting factor in raising D. sissoo and B. ceiba nurseries in Jhang where only 11% living plants could be recorded in a mixed nursery of the two affected species. Greaves and Khan (1978) observed the same type of damage to M. azedarach in a nursery at Chichawatni with more than 90% of the seedlings destroyed, while the seedlings of D. sissoo were virtually untouched, showing a preference to M. azedarach. During the survey the Forest Officer of Chichawanti informed that damage to M. azedarach nurseries was 100% and 75% in 1972 and 1973, respectively. Reports from India indicate that 30% seedlings of Neem (A. indica) and 12% of Eucalyptus spp. were damaged by cutting the plants at 5-7 cm above the ground level in Aravelli hills near Jodhpur. Up-rooting and pulling out of transplants/stockings is a characteristic behaviour of Indian crested porcupine. Ahmad and Chaudhry (1977) reported that in scrub forests Agave spp. was completely wiped out several times soon after transplanting but A. modesta was quite safe from this kind of damage. Also, newly planted D. sissoo stumps were usually pulled. Nawaz and Ahmad (1974) reported up-rooting of 4700 B. ceiba plants from two compartments (31 ha) at Changa Manga plantation. Damage to suckers of date palm (P. dactylifera) by up-rooting is also very serious in Punjab and Balochistan. One of the farmers (Dr. Jasra per. comm.) reported the loss of 500 suckers (100% damage) within a month on a farm near Bhakhar. ii. Damage to trees The data on debarking of mature irrigated plantation (Table 30) showed that M. alba, D. sissoo, E. camaldulensis and M. azedarach are the most susceptible trees species to

135 porcupine damage, while P. deltodes and T. aphylla are not attacked by this rodent. Higher debarking (15.35±2.10%), significantly infested by the porcupine, was observed in Eucalyptus camaldulensis. This is quite contrary to previous reports which pointed out a complete absence of damage to Eucalyptus in Pakistan (Mia et al., 2007; Khan et al., 2000). This indicates a natural phenomenon moreover exotic Eucalyptus spp. has started adopting the ecosystem of the area, and local pests/parasites have started attacking the species too. This trend is expected to increase with the passage of time. There has been virtually no debarking of T. aphylla in Rakh Gouharwala. There is no explanation for a complete immunity of the Tamarix to porcupine attack. Summary of the results on damage estimates on major forest plantations suggested that different forest trees are differently prone to porcupine damage. E. camaldulensis faced the highest damage (15.35±2.10%) in Daphar plantation followed by D. sissoo (15.18±1.79) and M. alba (12.38±1.86%). Shorkot plantation faced the damage of E. camaldulensis (14.97±1.98%) and Rakh Chaubara plantation showed the damage of A. procera (3.44±0.04%). P. deltoides are facing almost no damage due to porcupine attack. The damage in most of the cases was in the form of debarking of the lower parts of the trees, up to the height of 25 cm. Sometimes it results in complete girdling. The complete girdling may sometimes causes death of the trees, yet in most cases the girdling and partial debarking may effect the radial growth of the plant (Storm and Halvorson, 1967) and hence renders it to secondary termite attack which also affects the quality of wood. The damage to tree plantation of the same species appears to vary in different areas. This can be expected under the difference in the density of porcupine population and different degree of the food available in wild area around the plantation. It happens when porcupine prefers wild vegetation rather than opting for the forested plantation/agricultural crops, having a higher human activity, risking the life of the organism. The general observation suggests that dead bark of tree is not favoured by porcupines. It just peals off the bark in order to access the inner part, i.e., cortex, xylem and phloem. The characteristic sign on the inner bark appear as scratching /engravings, are prominent through the collective efforts of both upper and lower incisors. However, in case of tree stocking (

136 above ground at an angle of 45º which is a characteristic sign of porcupine damage. Eglitis and Hennon (1987) observed that Sitka spruce (33% damage) appeared to be preferred over western hemlock (15% damage) by E. dorsatum, as a host tree in conifer stands in southeast Alaska. Similarly, Woods and Zeglen (2003) reported E. dorsatum damage to Sitka spruce (80% damage) forests of north-costal British Columbia, Canada, where the coniferous host Sitka spruce was most preferred. In Kundian, D. sissoo was preferred over E. camaldulensis and opposite of it appeared in Bhakhar plantation. In AJ&K, Ahmad (1990) observed that P. roxburghii and M. azedarach were the most preferred trees while Ailanthus altissima and R. pseudoacacia were least preferred ones to porcupine damage. In India, porcupine preference to coconut palms (46% damage) was significant over Agave americana (15-30%) and Caryota urens (15-20%) in Dakshina in Kannada region of Karnataka (Girish et al., 2005). The debarking activity varied within young palms (<5 years) and old palms (>30 years), young receiving more damage than the old ones. It has been concluded from the all above discussion: Conclusion: Indian crested porcupine, Hystrix indica, is a pest which causes severe damage to forest plantation as well as to farm crops in various agro-eco-zones. The analysis of the stomach contents and fecal pellet samples collected during different seasons and geographical locations suggest some degree of variation in composition and prevalence of the food species. This is expected that the available physico-biotic conditions cause seasonal and geographic variations in the prevalence of different plant species in different localities and during different seasons. According to the results of this study it damages the crops like Zea mays, Triticum aestivum, Saccharum officinarum, Arachus hypogea, Brassica oleracea, Hordeum vulgare and Sorghum vulgaris. As for as damage to natural and irrigated forest plantations are concerned, this pest particularly damage bark, roots and shoots of Morus alba, Dalbergia sissoo, Melia azedarach, E. camaldulensis, Bombax ceiba and Alibizzia procera, which ultimately affect supply line of timber to sports, furniture and wood based industries, all of which are of great economic concern in this country. In forest nurseries, it severely damages the young nursery plants which seriously hamper the productivity of the forest and reforestation efforts. Regarding the diversity of food of porcupine, it was observed that

137 porcupine has more diverse diet in irrigated embankments of link canals and less diverse diet in rainfed Pothowar belt.

138 Recommendations: In Pakistan, Hystrix indica is abundant and distributed all over the country. It has been identified as a serious pest of traditional as well as non-traditional crops. So to avoid the damage caused by porcupine, the measures should be adopted for its control as mentioned below:  The control of porcupine should be achieved by carbon monoxide and aluminium phosphide (7 tablets of 3 g) fumigation effective only in loamy and silty soils.  In the stony and hilly areas like rainfed Pothowar belt where porcupine burrows have many smaller openings, causing the fumes leakage leading to failure of control campaign. So poison baiting should be done instead of aluminium phophide fumigation in such areas.  Anticoagulants like coumaletralyl bait can also be used for control of porcupine population although its results are delayed yet 100% mortality occurs.  The agro-forestry practices should be adopted in irrigation plantations and reforestation areas to have minimum seedling loss.  The control of porcupine must start from October, to avoid winter damage to forest plantations.  A sustained pest vigilance coupled with constant monitoring is suggested to check for any recurrence of the pests after implementing control measures.

145 Chapter - V SUMMARY The Indian crested porcupine (H. indica) is a serious vertebrate pest in Pakistan. Little has been studied about the food habits of this species because of its shy nature and nocturnal habit. In present endeavour the study of food habits, feeding seasonality and assessment of damage was made. One hundred thirty one porcupines were trapped and 480 fecal pellets were collected from different agro-ecological zones of the Punjab (Pakistan). The overall picture based upon analysis of stomach contents and fecal pellets revealed that the porcupines were mainly dependent upon plant material mostly pertaining to species like Z. mays, T. aestivum, S. officinarum, M. alba, M. azedarach, H. vulgare, E. camaldulensis, D. sissoo , B. compestris and A. modesta . The whole study period was divided into four seasons: spring (February – April); summer (May–August); fall (September-October) and winter (November-January). During these periods the relation of food and feeding behavior showed maximum relative frequency in summer (3.78) followed by fall season (3.61), spring (3.67) and winter (3.67); spring and winter relative frequency was equal in nature. Relative frequencies among the food items noted in different locations are as under: A. modesta (8.78), A. hypogea (1.90), C. polygonoides (4.54), D. annulatum (0.28), D. viscose (1.69) and L. aphaca (0.57) were found only in one location. A. tenuifolius (3.416), M. sativa (0.42), S. tuberosum (0.10), C. ciliaris (5.419), B. campestris (1.570), P. sativum (0.21), C. jawarancusa (0.46) and T. terrestris (5.02) were found in two locations. A. procera (3.00), C. annum (0.21), S. melongena (0.63), V. mungo (1.04), P. guajava (0.71), L. esculentum (0.38) and C. maxima (0.16) were found in three locations. B. oleracea (0.96), A. cepa (0.823), Mangifera indica (1.35), M. indica (0.34) and S. munja (1.15) were found in four locations. S. officinarum (0.69), B. ceiba (4.11), S. nigrum (0.98), M. azedarach (4.16) and M. alba (3.98) were found in five locations. H. vulgare (1.69), Z. mays (6.37) and E. camaldulensis (6.12) were found in six locations. D. sissoo (6.39), S. halepense (3.83), D. bipinnata (0.54) and C. melo (0.68) were found in seven locations. S. vulgaris (6.54), T. aestivum (8.56), C. dactylon (7.84), C. rotundus (1.58), Z. jujube (2.70), P. juliflora (9.85), unidentified (7.944), unknown plant parts (11.12) and other (1.38) were found in eight locations.

146 Regarding the diversity of food of porcupine, it was observed that porcupine had more diverse diet in irrigated embankments of link canals and less diverse diet in rainfed Pothowar belt. The most important porcupine damage, however, occurred in forestry. Damage estimate of M. alba 12.38±1.86, A. procera 3.44±0.04, D. sissoo15.18±1.79 and E. camldulensis 15.35±2.10% in different irrigated forest plantations of Punjab. Crops of economic importance such as maize, wheat and groundnut were found severely damaged in irrigated plains and rainfed Pothowar belt. Among the vegetable, pumpkin, okara, bitter gourd and onions were badly damaged. In rangelands, different species of grasses such as S. helepense, C. ciliaris and C. jawarancusa were severely affected. Dirt raised embankments of link and irrigated canals became weakened because of most favourable denning sites for porcupine. A marked shift in diet of H. indica occurred with seasonal and geographical variations which could largely be attributed to availability of food species or their parts. Hope fully our findings will help in overcoming the menace of porcupine attack on commercial species of crops and trees by introducing species of lesser economic importance within our crop/tree regimes. The results of this study will, help to devise strategies for its management and preventing damages to crops of economic importance. .
