I boschi dei Colli Berici

Abstract

THE WOOD COENOSES OF COLLI SERICI (VICENZA, NE lTALY). The syntaxonomical, chorological and ecological features of the wood coenoses occurring in the hilly area of Colli Berici (Vicenza, North-Eastern Italy) are described. Three associations are recognized: the suboceanic Omithogalo pyrenaici-Carpinetum Marincek et al. 1983, Buglossoido-Ostryetum Gerdol et al. 1982 em. Poldini 1988, which prefers more marked thermic excursions, and the synanthropical Lamio orvalae-Sambucetum nigrae Poldini 1980. The first association includes two coenoses: the gorge woods, characterized by species of Tilio-Acerion Klika 1955 and Lamio Acerenion Marincek I 990, and the subass. caricetosum pilosae Marincek et al. 1983. The Buglossoido Ostryetum is subdivided into two subassociations: typicum and pistacietosum terebinthi Poldini 1988. The latter is characterized by the presence of taxa of Quercetea ilicis Sr.-Sl. 1947 and by a higher incidence of species belonging to the the Mediterranean s.l. chorological type; its differential species are proposed. The marginal presence of two further associations (Melampyro vulgati-Quercetum petraeae s.lat. Puncer et Zupancic 1979 em. Zupancic 1994 and Carici umbrosae-Quercetum petraeae Poldini 1982) is hypothesized.
