A study on the Hazel Grouse, Bonasa bonasia, was carried out in the Carnic Alps in the period 2008-2010. The aims were to determine some parameters related to breeding activity and territoriality and to identify conservation actions in favour of the species. The results show a reduction of the area where the species is established compared to the past and a distribution concentrated in favourable zones. Bonasa bonasia is losing territory especially in low mountain areas, in the outermost Alpine river valleys and in the Prealps. Abandonment of traditional agricultural, silvicultural and pastoral activities, habitat fragmentation and anthropization are among the main causes of this situation. Finally, some measures aimed at reversing the tendency to rarefaction and the related problems are reported.
