Fig. 8.7.1 REM (Marche Environmental Network). Vegetation Landscape Units (ULV). ULVs
were defined using a complex from the vegetation map (defined by different relationships between
geology and bio-climate units), complemented by relationships with settlement-covered surfaces.
Blue represents ULVs based on fluvial and alluvial deposits; violet represents those based on
sandy substrates; yellow for those based on clay substrates; green represents those based on
calcareous substrates; gray represents those based on travertine
