Abstract
Relationships between the spatial and temporal distribution of long-lasting snow-cover and the spatial distribution of plant communities above timberline were studied on Mount Prado (2054 m), a representative sample area of the summit vegetation of the Northern Apennines (Italy). The spatial analysis was carried out by creating a geographic information system. Vegetation map and two snow-cover maps were both georeferenced to a scale 1 : 2000. The vegetation map is formed by 28 plant communities (including 7 combinations of communities, or vegetation mosaics) distributed into 277 map polygons. The maps were compared by an overlay procedure. The results show that the six plant communities (including three mosaics) which have a June snow-cover higher than 60% are diversified by a snow-melting gradient from early June to mid-July. The slowest snow melt corresponds to a snow-bed community (Salicetum herbaceae) and to a mesophytic grassland (Trifolium thalii-Festuca puccinellii community, Luzula alpino-pilosa variant).
