Résumé
The ecological characteristics of 22 colonies of Alpine Marmot (Marmota marmota), in the Orsiera-Rocciavre Natural Park, has been analysed, during 1990 and 199l. The burrows' density (per 100 m2) has been calculated and correlated with the number of animals seen and other territorial variables (altitude and site conformation). In all burrow systems the dimension of each burrow (height, width and area) has been evaluated. The marmot density has been calculated in 3 sample areas.
