ABSTRACT

Red deer (Cervus elaphus L.) is in many parts of the world ecologically important and highly popular game species. Its population densities and environmental impacts largely depend on habitat suitability, which in turn is under strong influence of humans. Wildlife management intentionally improves habitat suitability, while forestry’s impacts on red deer are mostly unintentional. In both disciplines the full extent of these impacts is poorly understood. To better understand habitat use and improve management of red deer, we studied the impacts of multiple environmental and historical factors, mostly anthropogenic, on red deer spatial distribution in Slovenia. We found that the probability of red deer presence and population density are higher close to locations of historic (> 100 years ago) red deer reintroduction sites and in large continuous forest complexes. The finding is important for forecasting future red deer distribution and population dynamics. Population density is also positively dependent on proximity to supplemental feeding sites, the proportion of spruce stands in pole-stage and the share of forest young growth, which is important for preventing unwanted impacts of red deer on forest. The approach used by this study and its results are also useful for improving habitat ranking of hunting grounds, which some countries use in wildlife management planning.
