Marmots has been introduced in the reserve of Mont-Vallier (Ariege, Pyrenees) from 1961 to 1972 using alpine strains obtained in Vanoise (Savoie) and Queyras (Hautes-Alpes). A total of 18 individuals has been released. The studied area, which includes the reserve of Mont-Vallier and its close surroundings (a total of 12,800 ha), has been divided in meshes 200x200m on the coordinates from Lambert zone III in maps IGN (Institut Géographique National). With this meshing we noted the meshes where marmots were found in 1997. For each mesh the mean altitude, exposure and slope were noted. We also noted for each mesh the kind of overall biotope: forest, moor and meadows, rocks, ponds. We compared, for the ecological factors, the available meshes and the meshes used by marmots in order to determine the biotopes which are chosen by marmots in its present stade of space colonization of the reserve. In 1996 and 1997 we visited all the marmot families in the reserve to evaluate the density and the struture of the population.
