Modelling forage potential for red deer: A case study in post-disturbance young stands of rowan

摘要: Recently, the red deer ( Cervus elaphus ) population has increased considerably and caused serious damage in forest stands Slovakia as well other Central-European countries. Rowan Sorbus aucuparia L.) is tree species that most intensively browsed stripped by deer, especially during young stages of development. Our research focuses on estimating rowan mass consumption which developed after large-scale wind disturbance occurred Tatra National Park 2004. New models were for components are potentially edible using tree-base diameter an independent variable. The results showed contribution particular to accessible forage depended size (tree-base diameter). At stand level, total potential with increase size. However, whereas quantity bark available stripping size, browsing (leader shoot branches foliage) decreased. For instance, stem a mean 20 mm 50 was 15% 50%, respectively. Theoretically, if all consumed (considering coverage 50%) growing within area 100 m2 might provide sufficient one adult ca. 10 days. It suggested should not be removed from territories high order decrease other, commercially important, species.
