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

The vegetation of the Montalto Natural Reserve (Tuscany) and its botanical conservation aspects. A vegetation survey of woods and shrublands of the Montalto Natural Reserve was carried out by means of phytosociolocical relevés and of literature data analyses. The survey led to the recognition of several vegetation types: termophilous and mesoigrophilous beech communities; Tilio-Acerion coenoses; mixed woods with Carpinus betulus; Quercus cerris, Acer obtusatum and Ostrya carpinifolia; semimesophilous shrublands. 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.
