Il paesaggio vegetale del territorio collinare anconetano

Plant landscape of the hill territory around Ancona. - The phytosociological study of the vegetation of the arenaceous, peliticous-arenaceous, arenaceous-peliticous and alluvial lands of the hilly Ancona sector, in the east- central part of the Italian peninsula on the Adriatic side, permitted the reconstruction of different vegetation series which are distributed in close relationship with the area’s lithological formations. The edaphous-xerophilous series of the arenaceous substrata corresponds to the Roso sempervirentis-Querœto pubescentis sigmetum; the climatophilous series of the peliticous-arenaceous substrata is represented by the Asparago acutifolii-Ostryeto carpinifoliae sig-metum, while the climatophilous series of the Lonicero xy los tei -Querceto cerridis sigmetum is found on the arenaceous-peliticous substrata. The flood plain series of the oldest alluvial terraces corresponds to the Rubio peregrinae-Carpineto beluli, while in more recent ones the edaphous-hygrophilous series of the Symphyto bulbosi-Ulmeto minori s sigmetum is represented By integrating these si g me ta, the geosigmetum of the hilly territory of Ancona is obtained.
