摘要: Obtaining estimates of animal population density is a key step in providing sound conservation and management strategies for wildlife. For many large carnivores however, estimating difficult because these species are elusive wide-ranging. Here, we focus on the first Eurasian lynx (Lynx lynx) French Jura Vosges mountains. We sampled total 413 camera trapping sites (with two cameras per site) between January 2011 April 2016 seven study areas across counties obtained 592 detections over 19,035 trap days mountains 0 detection 6,804 Based coat patterns, identified number 92 unique individuals from photographs, including 16 females, 13 males, 63 unknown sex. Using spatial capture-recapture (SCR) models, estimated abundance 5 (SE = 0.1) 29 (0.2) 0.24 (SE = 0.02) 0.91 (SE = 0.03) 100 km2. also provide comparison with nonspatial discuss observed discrepancies. Our yet another example advantage combining SCR methods noninvasive sampling techniques to estimate wide-ranging species, like carnivores. While densities comparable other populations Europe, fact that detected no alarming. Connectivity should be encouraged mountains, Palatinate Forest Germany where reintroduction program currently ongoing. will help setting baseline status France.
