Knowing prey distribution and density in areas where carnivores are present is an important condition to have a better understanding of carnivore movements (Karanth et al. 2004 ; Herfindal et al. 2005). Southeastern of Norway has recently been recolonized by the European Lynx (Lynx lynx) and the wolf (Canis lupus) and in order to be able to predict these carnivore movements, it is important to produce detailed models of their prey abundance and habitat use. Roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and mountain hare (Lepus timidus) are commonly hunted by lynx and wolf in Norway (Odden et al. 2006, Wikenros 2001, Müller 2006) but even if these species are well present in the southeastern, no distribution maps are available yet. Using hurdle models, we create the prey maps and test the extent of predictive modeling. Finally, we discuss the limits existing when trying to develop and use predictive maps at large scale.

In the last forty years, tolerance of anthropic environment has allowed large carnivores to recolonize and expand their distribution in Western Europe. To assess the full potential and consequences of this return, habitat use and landscape modeling are particularly useful tools that allow conservationists to come up with reliable prediction, and policy makers to anticipate management planning. The considerable power of dispersal and important space requirements of these species necessitate large-scale modeling, but it is essential to work in parallel at very fine scale, as carnivores’ impact on human societies is mostly felt at local level. Management of large carnivores must therefore be multi-scalar, with different decisions taken at multiple levels. With the return of the Eurasian Lynx (Lynx lynx) to lowland Western Europe, in regions of relatively high human densities, conservation- planning decisions must be knowledge based. Different approaches will be followed to analyze data at finer and larger scales. These include differential distribution and tolerance of lynx to fragmentation and anthropization, influence of landscape on lynx predation and the development of a conceptual model aiming at responding efficiently to conflicts with human populations. Results will permit the development of a lowland Western Europe habitat model, and to propose conservation measures adapted to the return of this emblematic carnivore.

Tolerance of anthropic environment has allowed large carnivores to recolonize and to be reintroduced within Europe in the last forty years. This indicates that, even in areas where the return of large carnivores seems unlikely, their presence and establishment is possible, even in highly modified environments. In the current context of the return of large carnivores in Europe, there is a need for scientific conservation tools to assess the full potential and consequences of the return of large carnivores in Europe, and in particular to evaluate potential impact on game and livestock. Today, the return of the Eurasian Lynx (Lynx lynx) in areas where it has been absent for long periods is becoming increasingly probable, and this requires further investigations. Three main lines of research will be particularly important: the use of habitat by Eurasian Lynx, the effect of habitat on predation behavior, and potential sources of conflict with human populations. The research project will address fine scale habitat use, the effect of prey‘s spatial variation on Lynx predation behavior, the use of different statistical methods to estimate Lynx‘s viability in various habitats and landscape, and a review of current conflicts throughout Europe. Results should allow better understanding of the Lynx redeployment potentials in lowland Western Europe [less ▲]
