Successional Pathway of Mediterranean Ultramafic Vegetation in Central Italy
Alessandro Chiarucci
; Italija
Sažetak
The mam plant communities of ultramafic (serpentine) outcrops of a Mediterranean area in central Italy are described and their successional pathway discussed. Four vegetation stages are distinguished: a) an endemic garigue stage, with high percentage of exposed rocky soil belonging to Armerio-Alyssetum bertolonii; b) a garigue stage similar to the previous one but with several Mediterranean evergreen shrubs; c) a closed evergreen maquis of Mediterranean type belonging to Viburno-Quercetum illicis subass. ericetosum; d) an evolved evergreen forest stage with some deciduous species belonging to the Viburno-Quercetum ilicis subass ornetosum. While the pioneer stages are characterised by several endemic serpentinophytes, adapted to the peculiar environmental conditions of ultramafic shallow soils, the more evolved vegetation stages, on the contrary, are typical of Mediterranean environments and do not show any serpentine characterisation.
