Assessing conflicts between winter recreational activities and grouse species

Mountain environments provide habitats for many wild animal species and are of great importance to recreational activities. In the European Alps, winter recreation activities such as ski mountaineering are becoming increasingly popular, which may lead more often to disturbance of Alpine wildlife. Assessment of ski mountaineering activities and related potential conflict zones is needed to implement protection measures and to guide skiers towards nature-friendly behaviour in sensitive locations. Yet basic data regarding frequencies of ski mountaineers is still missing at regional scale. For the Region of the Tyrol (Austria), this study therefore aimed to advance methods of assessing ski mountaineering activities for use in the spatial analysis of conflict zones with grouse species. We overlaid high-resolution information on the spatial and temporal distribution of ski mountaineers from crowd-sourced data (Strava) with distribution maps of capercaillie (Tetrao urogallus L.) and black grouse (Tetrao tetrix L.). Our results indicate that ski mountaineering activities affected 10.3% of the distribution area of black grouse and 8.6% of the distribution area of capercaillie. The raw crowd-sourced data was pre-processed with local information on skiing resorts, cross-country trails and infrastructure and use of the tested method was validated, with good spatial resolution (0.076 km² per minimum mapping unit) for large study areas. We identified four intensity classes of ski mountaineering activity, which were randomly distributed in the study area. The spatial distribution of ski mountaineering activities showed an accumulation of activities in the south of the Inn valley. Our results could provide a valuable basis for developing mitigation measures and strategies in order to reduce the disturbance of Alpine wildlife by ski mountaineering.
