Black grouse

Here is a picture of Black grouse

Alpine wildlife is impacted by land-use changes (abandonment and encroachement of pastures) and the growing tourism industry (especially snow sports activities). We used the Black grouse as a research model because its timberline habitat largely overlaps with recreational activities in the Alps. We had two research modules. In the first, we tried to understand the effects of recreation on species eco-physiology (stress, activity budget), behaviour (habituation to humans) and demography (population abundance, breeding success, survival rate); we then developed spatially-explicit models for delineating major areas of human-wildlife conflicts where quiet winter refuges should be implemented. In the second module, we investigated the breeding habitat requirements of Black grouse in order to provide recommendations for habitat management measures by foresters. Collaboration with local authorities and stakeholders, through the Valais field station of the Swiss Ornithological Institute, warrants that the proposed measures are effectively implemented....
