We investigated the preferences shown by Tberian lynx (Lynx pardinus) for structures and sites for denning in Donana National Park. Lynx proved to be highly selective regarding the features of the natural structures selected, but their preferences concerning the characteristics of the habitat for the denning sites were not so evident. All located litters were born inside hollow trunks with very large cavities (mean area=0.40 m2). Later, they were moved into bushes characterised by their large size (mean area=201.7 m2) and protective capabilities. We used logistic regressions to explore the relative strength of association between the selection of dens, the characteristics of their structure and those of the habitat around dens. The regressions indicated that the physical nature of dens was more important for breeding lynxes than habitat features (like prey densities or structure of vegetation). Preserving old growth habitats is important for the conservation of the endangered Tberian lynx because they provide suitable breeding structures.
