- Abstract:
- As the black grouse (Tetrao tetrix) is considered an umbrella species for the sensitive area along the timber line, a cross-border habitat suitability model was developed using the software MaxEnt. The goal of this thesis was to determine the habitat potential for the black grouse in the Karwendel Mountains, which are located in the Eastern Alps between Bavaria in Germany and Tyrol in Austria. The developed habitat suitability model showed a higher probability of occurrence for black grouse at north and east exposed altitudes between 1.400 and 1.700 meters above sea level. Important for the suitability was the tight interconnection between human influenced areas as for example mountain pastures supporting a mosaic of different biotopes and structures of landscapes. Subalpine and alpine grass- and heathland landscapes also had a positive influence, whereas rocky landscapes without vegetation had a negative impact on the probability of occurrence. The developed model was checked for plausibility by involving experts on site, whereby a very good conformity of the model output with the real situation could be determined. The model developed in this thesis was compared with other models for Bavaria and Tyrol, that had already been carried out to estimate the habitat suitability for the black grouse. In some cases, a lower predicted habitat suitability could be noticed along the national border than in the developed model. This may occur if environmental data is unavailable across the border and thus variables along the border are not calculated correctly. Therefore, cross-border exchange between colleagues, using the example of high-resolution spatial data, is absolutely necessary. Ultimately, the present habitat modeling for the black grouse contributes to the decision-making process for efficient, cross-border and coherent area management in Tyrol and Bavaria.
