Aim European wildcat Felis silvestris silvestris (Schreber, 1775) populations are suffering considerable threats, making conservation action a priority. In Scotland, the establishment of Special Areas of Wildcat Conservation (SAWC) have been recommended; however, few studies have addressed wildcat ecological requirements in this region. Our goal was to identify the environmental determinants limiting wildcat occurrence at a broad scale in Scotland. Location Scotland, Europe. Methods We examined data from the recent Scottish wildcat survey (20062008) and the National Biodiversity Network (NBN) Gateway. Presence and pseudo-absence data from 71 sampling units (10 km x 10 km) were used to generate models explaining probable wildcat occurrence. Models were built based on three pre-established hypotheses using generalized linear models (GLM-Logit). Results European rabbit presence, high rodent diversity and the prevalence of large grassland areas were positively associated with probable wildcat occurrence. Heather moorland, sampling units with few grassland patches or secondary watercourses and higher elevation ranges were associated with probable wildcat absence. We found no evidence that forested areas or human disturbance were influential. Main conclusions Our results suggest that wildcats may benefit from heterogeneity within the landscape matrix, reinforcing the idea that the wildcat is not primarily a forest species (as has traditionally been inferred from studies of the species elsewhere). We conclude that less mountainous areas, with a diverse landscape including woodland and grassland supporting rabbits and a diversity of small rodents are a priority for wildcat conservation efforts.
