La populazione di marmotta (Marmota marmota) nel parco naturale Orseira rocciavrè. The population of alpine marmot (Marmota marmota) in the Natural Park Orsiera-Rocciavre [La population de marmotte alpine (Marmota marmota) du parc naturel d'Orsiera-Rocciavre].

Résumé

The author, warden of the Park, has carried out a research on the population of Marmot in the Park. The protected area includes the massif of Mont Orsiera and Mont Rocciavrè located between Chisone, Susa and Sangone valleys. The aim of the research has been to draw a map of the zones haunted by the Marmot. The position (orientation, altitude, slope) and their distribution on the territory have been studied. In some areas botanical aspects were considered. The preliminary results show a correlation between the presence of the marmots and rich floristical pasture tipology. The species probably have a role as environmental indicator.
