- Abstract:
- Human activities in the cultural landscape often overlap and can lead to conflicts between the user groups. Also in the Alps different land use interests meet each other. The protective function of the forest for infrastructure in the valleys plays an important role. Therefore, respective forest stands are necessary. But wildlife also uses the habitats in the mountains and hunting tenants manage many of these populations. This causes a field of tensions between tourism, forestry and hunters, in which the wildlife remains. Numerous studies prove a decline in chamois populations in the Alps. In this work, the situation of the chamois (Rupicapra rupicapra) in a project area in Vorarlberg was investigated. On the one hand, an overview of the population structure should be gained. Therefore existing data of countings and hunting bags were analysed. This analysis showed that during the surveyed time period the harvest has strongly shifted on the expense of the bucks. Most of these bucks were hunted in the youth class. The bucks harvested on sensible forest stands (designated as „Freihaltungen“ and „Schonzeitaufhebungsflächen“) apart from the hunting plan are reported as „Schadwild“ (wildlife causing damages). This quota has clearly increased in the last years and represented almost half of the hunted bucks in the most recent years. The high percentage of youth-class bucks harvested as „Schadwild“ indicates a pull effect of these focus hunting areas. Furthermore, on the basis of presence data of the chamois and some selected environmental parameters, the habitats suitable for the chamois were identified. For this purpose, two models for the probability of occurrence were calculated, one for summer and the other for winter habitats. The results showed clear preferences and in places an overlap of the suitable habitats with the declared areas of high hunting pressure due to damage disposition of the forest stands.
