ABSTRACT he bioecology of the wild boar Sus scrofa was studied in the Turkish province of Kırıkkale using field Tobservations and examination of 21 specimens collected from 2001 to 2003. Habitat, some breeding features, and morphometric data were recorded. The wild boar in Kırıkkale occurs mainly in forests, marshy areas and dense scrub. It selects scrub areas near hill tops as daytime resting sites. It feeds on some agricultural products in summer and is often hunted to prevent such damage. It produces its young in April and May. Morphometric data from specimens examined were consistent with the Turkish wild boar belonging to the nominate subspecies Sus scrofa scrofa but its taxonomy does merit further investigation. Key Words Wild boar, Suidae, ecology, taxonomy, Turkey ÖZET aban domuzu, Sus scrofa’nın biyoekolojisi Türkiye’nin Kırıkkale ilinde yapılan arazi gözlemleri ve 2001 ila Y2003 yıllarında toplanan 21 örneğin incelenmesi ile araştırıldı. Habitat, bazı üreme özellikleri ve morfometrik veri kaydedildi. Kırıkkale’deki yaban domuzu ormanlarda, bataklık alanlarda ve yoğun çalılıklarda bulunur. Yaban domuzu gündüz dinlenme yeri olarak tepelerin zirvesine yakın çalılık bölgeleri seçer. Kırıkkale’deki yaban domuzu yazın bazı tarım ürünleriyle beslenir ve bu gibi zararları önlemek için sık sık avlanır. Yaban domuzu nisan ve mayıs ayında yavru verir. İncelenen örneklerden elde edilen morfometrik veriler Türkiye yaban domuzunun ait olduğu nominatif alttür, Sus scrofa scrofa’ya uygunluk göstermekte, fakat yaban domuzunun taksonomisi için daha fazla araştırmaya gerek vardır.

The coldest month is January (average -3°C) and hottest month is July (average 27.6°C). The wild boar is the only member of the Suidae present in Turkey and was first reported Field observations by Gray (1868). There are limited records available Field studies were concentrated in the wildlife concerning the distribution, ecology, biology and areas of Sulakyurt, Balişeyh and Delice district, taxonomy of the species in Turkey (Tunçok, 1935; which contain almost 70 percent of the total Ellerman and Morrison-Scott, 1951; Mohr, 1960; forest area in Kırıkkale. Ecological data were Huş, 1967; Groves, 1981; Turan, 1984; Mayer and obtained from direct observations of animals Brisbin, 1991; Genov, 1999). However, wild boar in the field, animals shot, winter tracking and are an important game species in Turkey (Eroğlu, rooting damage to grassland or damage to crops. 1995) and have the potential to cause damage to Boar damage was identified from feeding and agricultural crops (Andrzejewski and Jezierski, 1978; snout marks, faeces, live sightings and farmer Genov, 1981; Schley and Roper, 2003; Wilson, 2004). complaints. Observations were made periodically, They are therefore of interest both economically at night between 23:00 and 08:00 h for direct and ecologically. observation of the animals to record habitat use, group size and composition, and in daylight, The present study aims to reveal for the first between 08:00 and 15:00 h, primarily to inspect time some biological and ecological characteristics for damage, field signs and record home range of Sus scrofa in Turkey and to help clarify its characteristics and habitat use. Field observations taxonomic status. were made from March 2001 to october 2003. Nighttime and daytime observations were made MATERIALS AND METHODS at two hours intervals. The time and frequency of direct observations were recorded according to the habitat type and season in which the animals Study area were seen. Kırıkkale province is located in the central Anatolian region (33°31’-E, 39°50’-N) and occupies an area of 4615 km2. It is surrounded by Taxonomic data Koçudağı mountain (1778 m) lying NW-SE, Dinek Specimens of wild boar were obtained from mountain chain (1742 m) S-SE and Küre mountain animals shot dead by hunters or caught alive (1450 m) NE-SW. Mean altitude of the province is during the field studies from 2001 to 2003. The 700 m. The total estimated forest area is 49530 ha animals were divided into three age-groups; (approx 11% total area), composed of a mixture of infant, juvenile and adult, depending on their oak (Quercus sp.) and pine (Pinus sp.) forest. The cranial and dental structure, coat colour body remainder of the area is dominated by farmland size and field notes. Where possible, live-weight, S. İnci, İ.Albayrak and C. J.
