Eurasian lynx natal den site and maternal home‐range selection in multi‐use landscapes of Norway

Abstract

AbstractIn carnivores, securing suitable den sites with associated early maternal home ranges is important for successful reproduction, and understanding natal den site selection is essential to ensure that these habitats are protected from human disturbance. This study investigated Eurasian lynx Lynx lynx natal den site selection across multiple use landscapes in Norway and explores whether the selection of early maternal home ranges across southern Norway involved a trade‐off of security for access to their preferred prey species, roe deer Capreolus capreolus. The characteristics of natal dens and home ranges from 33 reproductive events were quantified across south‐eastern and northern Norway. Natal dens were located in terrain further from the most accessible and disturbed areas (public roads) and in terrain more rugged than generally available. Early maternal home ranges were characterized by low human and low road density in rugged terrain and a selection for areas associated with higher or lower roe deer densities was not important in our analysis. Humans are the dominant cause of lynx mortality throughout Norway and our findings suggest that female lynx primarily chose areas that limited their interaction with people during the denning period.
