Résumé :	A study was carried out over three winter seasons (1995-1998) to evaluate the most important habitat parameters for Hazel Grouse Bonasa bonasia on the forest stand scale. The study area was situated in the Southern Limestone Alps in Austria. It was divided into two parts, reflecting two different forest management strategies: (1) SIMPLE, an age class system with clear-cutting, and (2) MULTI, multi-layered stands with selection felling. An analysis of the roosting sites and habitat use was conducted, as well as a dropping investigation and diet analysis. Monotonous even-aged forest stands, as well as multi-layered old forests, can provide Hazel Grouse habitats but, compared to the latter, monotonous forests are risky habitats because the suitability can depend on only one factor. The habitats in the age class forest are limited in time, whereas multi-layered forests offer habitats for a full rotation period.
