La vegetazione della Riserva Naturale Alpe della Luna (Arezzo, Toscana) ed i suoi aspetti di interesse botanico-conservazionistico.

The vegetation of the Alpe della Luna Natural Reserve (Tuscany) and its botanical conservation aspects -A vegetation survey of grasslands, shrublands and woods of the Alpe della Luna Natural Reserve was carried out by means of 79 phytosociolocical releves and of literature data analyses. The survey led to the recognition of several vegetation types: pioneer erbaceous communities; montane semimesophilous and mesophilous grasslands; different types of shrublands; eutrophic, mesoigrophilous and subacidophilous beech communities; chestnut woods; coenoses dominated by Carpinus betulus; Tilio-Acerion communities; woods with Quercus cerris, Acer obtusatum and Ostrya carpini/olia of different types. A vegetation map is reported. Finally we point out to the high naturalistic value of this area by listing floristic species and vegetation habitats of conservation relevance.
