abstract

A phytosociological study regarding the silver fir woodlands of the Basilicata and Campania regions is here presented. In the administrative territory of Basilicata, Abies alba occurs both in the Quercus cerris woodlands of the sub-montane belt (Physospermo-Quercetum cerridis abietetosum albae subass. nova) and in the Fagus sylvatica woodlands (Anemono-Fagetum, Aceri lobelii-Fagetum, Ranunculo brutii-Fagetum) along the whole altitudinal range of the montane belt. In phytosociological terms the presence of Abies alba within these community types is expressed as a “relictual/residual variant”. In the Campania region, in particular in the Alburni mountains, Abies alba occurs, in impoverished populations, almost exclusively in the montane belt of Fagus sylvatica woodlands (Anemono-Fagetum). In the Mount Motola massif, however, where the silver fir finds its best expression in the regional territory, the species is abundant especially in the upper part of the submontane horizon, where it forms a peculiar woodland type together with Fagus sylvatica, Ostrya carpinifolia and Acer obtusatum. For this community type a new sub-association named Anemono-Fagetum ostryetosum is here proposed.
