4939 Meghamalai landscape: A biodiversity hotspot Bhupathy & Babu

Mountains was largely used by British Explorers. The landscape has been identified as an important wildlife area by Rodgers & Panwar (1988). Meghamalai is largely under the control of the Forest Division (), which was a part of erstwhile Travancore Presidency prior to the Indian Independence. In 2009, 269.11km2 of the area was declared as Meghamalai Wildlife Sanctuary ( Government Gazette 2009). Considering its conservation importance, (the landscape forms a buffer to the existing protected areas such as Grizzled Squirrel Wildlife Sanctuary and Periyar Reserve); the area, along with the Grizzled Squirrel Wildlife Sanctuary, has recently been proposed as a © S. Babu Tiger Reserve (Fig. 1). In the present paper, we provide Image 1.

(Bhupathy et al. 2012). Rock formation of the area is The eastern fringe of the area (Varusanad) is covered largely composed of charnockites, granite gneiss and pink with tropical thorn forests. As per the working plan of the granites which have been deformed by folds and faults Tamil Nadu Forest Department (2005), the following forest (Palanivelu et al. 1988). types were identified (i) southern tropical west coast Fifty years of global climate data show variations in semi-evergreen forests, (ii) southern tropical moist mixed annual mean temperature across elevations, i.e., 24.10C deciduous forests, (iii) southern tropical secondary moist (in 500m) and 180C (in 1700m). Monthly mean minimum mixed deciduous forest, (iv) southern tropical dry mixed and maximum temperatures recorded in 500m were deciduous forests (v) southern tropical carnatic umbrella 21.80C and 30.60C respectively, whereas it was 16.10C thorn forests (vi) southern dry deciduous scrub forests. and 24.00C for 1700m (Bhupathy et al. 2009).

The Botanical this landscape by the British explorers which resulted Survey of India surveyed the area under District Flora in descriptions of snake species such as Silybura liura Scheme 1984–1991. Seven new species have been Günther, 1875, now Uropeltis liura (fide, Smith 1943), reported by Ravikumar (1999). Syzygium zeylanicum var. Silybura madurensis Beddome, 1878, now Uropeltis megamalayanum is endemic to the landscape. Sasidharan arcticeps madurensis (fide, Whitaker & Captain 2008) and et al.

Based on Fauna: Eighteen species of fishes belonging to 11 the collection of Harold S. Ferguson of the State Museum genera and four families have been reported from the at Trivandrum (1880–1904), Boulenger (1891b) described area (Table 1). Among them, 10 (55.5%) are endemic to Lygosoma subcaeruleum (Blue-bellied Tree Skink, now Western Ghats. Puntius ophicephalus, a rare barb has Dasia subcaeruleum). A second specimen was collected restricted distribution in the rivers originating/ flowing by Angus F. Hutton from High Wavy Mountains and the through this landscape (Silas 1951; Arunachalam et al. same was reported by Smith (1949a). This species was 2004). reportedly endemic to the area till recently (Harikrishnan Boulenger (1891a) described Ixalus (=Philautus) et al. 2012). Angus F. Hutton collected snakes from the travancoricus based on a specimen deposited at the British area during 1946–48. Most of these specimens are Museum (now Natural History Museum, London) by Mr. H.S. housed in the Museum of the Bombay Natural History Ferguson from Bodanaikanur (now Bodinayakanur). This Society and Natural History Museum, London (Hutton species (currently known as Raorchestes travancoricus), 1949a; Hutton & David 2009).

Encroachment and developmental activities— spurious, and currently this species is reportedly endemic About 5911ha of area has been encroached in 2896 to Sri Lanka (Erritzoe & Fuller 1997; Hoffmann 1996; encroachments. This includes 2060ha in Varusanad and Bhupathy et al. 2012). A most recent compilation showed 1721ha in Meghamalai Forest Ranges (Srinivas et al. that the area harbors 254 species belonging to 18 orders 2013). Apart from these, leased forest land for tea and and 55 families of birds, and this includes 11% (18 of 159 coffee estates in the upper elevations also take a major species) of threatened bird species of India and 88% (14 of share of natural forests. The estate workers depend on 16 species) of endemic birds of the Western Ghats (Babu natural forests for their fire wood requirement and for & Bhupathy 2013). There were a few intensive studies cattle grazing. New proposals on roads in this landscape on Grey Jungle Fowl Gallus sonneratii that addressed should be carefully studied and mortality of fauna due habitat use, nesting seasonality and threats on the species to vehicular traffic needs to be assessed (Bhupathy et al.
