abstract

The Festuca paniculata (L.) Sch. et Th. grasslands (Polygalo chamaebuxi-Festucetum paniculatae ass. nova) in the Pennine Alps (Piedmont, Italy). Results of a phytosociological study on Festuca paniculata (L.) Sch. et Th. grasslands in the Pennine Alps (Italy) are herein presented. The studied area is located in the northern district of Piedmont, under the influence of subatlantic climate. The vegetation study has been performed throught 13 phytosociological relevés. All data were submitted to multivariate statistical analysis. A new association, Polygalo chamaebuxi-Festucetum paniculatae ass. nova, was defined for the Pennine and Lepontine Alps, including the community previously described by Vittoz et al. (2005) in Canton Ticino (Swissland). Chorological, synecological and syndynamical datas were described in the paper, compared to the other Festuca paniculata alpine associations.
