Scree vegetation of the south-eastern zones of Abruzzo, Lazio and Molise National Park. This paper is a contribute to the coenological and sintaxonomical knowledge of Abruzzo National Park scree vegetation. The study area coincides with the limestone mountainous chains of Serra Rocca Chiarano and Serra Le Gravare which are located in the eastern zone of the National Park. The vegetation has been investigated through the Braun-Blanquet phytosociological approach. The vegetational data have arranged in a binary matrix and further treated with multivariate analysis procedures. Different micro-geomorphological sectors and consequently different ecological conditions can be distinguished into the “scree” system. Each microgeomorphological sector is characterized by a particular interaction of physical parameters such as altitude, aspect, slope, clasts stability and dimension.
