The snow-bed vegetation in the Northern Apennines was studied by the Braun-Blanquet method. The phytosociological relevés were classified by numerical methods. Four main vegetation types were identified: Salicetum herbaceae, community of Carex foetida, Poo-Cerastietum cerastioidis and Oligotricho-Gnaphalietum supini. The latter was described as a new association. The vegetation types were ecologically characterized by an indirect gradient analysis based on principal component analysis. The results were interpreted by means of: i) geomorphological observations, ii) soil profiles, iii) measurements of the length of the snow-free period.
