abstract

The vegetation of the "Bosco di Oricola", a Quercus robur-Carpinus betulus woodland in Central Apennines (Abruzzo - Italy). In this paper a phytosociological analysis of the vegetation of the "Bosco di Oricola" (Western Abruzzo) is presented. The biotope covers 400 hectares, between 570 and 640 m a.s.l., on clayey-sandy lacustrine deposits. The forest is well preserved and is made mainly of Quercus robur, Carpinus betulus and Tilia cordata.
The new association Arisaro proboscidei-Quercetum roboris is described, along with the subassociations typicum, quercetosum petraeae and viburnetosum opuli. Salix cinerea communities, belonging to the alliance Salicion cinereae, are also found on marshy soils.
In Central Italy, most woodlands dominated by Carpinus betulus usually lack characteristic species of the Carpinion betuli, and therefore usually belong to the Quercetalia pubescenti-petraeae or - in cooler habitats - to the Geranio striati-Fagion. The association here described, instead, clearly belongs to the Carpinion betuli, and is therefore the best preserved relic of this alliance in Central Italy. It probably represents also the southernmost stand of the alliance in Italy.
