||The development of ski touring and snow shoeing has led to an increasing human presence in mountains in wintertime. Wintertime is a difficult time for wildlife, due to rough weather conditions that cause animalsdifficulty to move and higher energy expenditure at a time where food is scarce.Yet, territory managers have very few data concerning the perception of wildlife by visitors. In addition, their impact (extensive travelling, displacement of feeding and resting areas)on wildlife is difficult to quantify. A research program has been led on the Bauges mountain range in order to deal with these issues. As local managers became interested in the impact of winter recreational activities, the Regional Natural Park got involved in the campaign « Respect to Protect » to promote a more respectful visitor behaviour.Thus, a partnership was set up with EDYTEM lab in order to get a better understanding about these visitors, their types of practice and their perceptions. .
