In order to understand the processes engendered by different faunal elements in naturalsystems, and to plan how such systems should be managed and conserved, it is essentialto start by determining the presence of those faunal elements, even large mammals. The entire range of North Anatolian Mountains provides suitable sheltering and feeding habitatsfor large mammals. The region stretching between Köroğlu Mountains (west) and IlgazMountains (east) is one of the most important Anatolia’s wildlife corridors. We located andidentified the species of large mammals in the Ilgaz Mountains, as well as specific habitatsused by them. Field studies carried out in this region during April-August 2017 resulted in180 records of nine different species of large mammals: Lepus europaeus, Ursus arctos, Canislupus, Vulpes vulpes, Lynx lynx, Meles meles, Sus scrofa, Cervus elaphus and Capreolus capreolus. To obtain those records took 621 days of studying with camera traps. Among thosespecies, European hare was the most frequently recorded herbivore (101), and brown bearwas the most frequently recorded carnivore (19). Both hare and roe deer displayed clustereddistribution patterns in the region. The analysis of our records showed that lynx, boar, andfox were strictly nocturnal; whereas hare and wolf were predominantly nocturnal. We alsoobtained records of the cubs of many large mammal species (bear, lynx, boar, red deer, roedeer) although we did not encounter any large mammal nests during the study.
