Abstract
Spatial distribution of the individuals belonging to different species of the Seslerio-Caricetum sempervirentis in the Dolomites was investigated by means of 16 transects each of 2 metar lenght. Along each transect all individuals of vasculars plants growing along the axis were registered. The elaboration was carried out on the 13 species occurring most frequently, on the basis of binary association. The frequences observed differ in general significantly from a random distribution. In some cases there is the tendency for a species to occur more frequently in contact with individuals of certain species and avoids other species. In particular the two dominating species {Sesleria albicans and Carex sempervirens) seem to avoid each other and to be in contact with some preferential species. Consequently, in the community there is the tendency towards a differentiation of microniches. These relationships are explained as a consequence of growth form and characteristics of soil.
