abstract

The plant landscape of Monte S. Pancrazio ridge (Umbria - Central Italy). Results of a geosynphytosociological study regarding Monte S. Pancrazio calcareous ridge (Umbria - Central Italy) are here presented. The study area is located in the southern part of Umbria Region, Terni Province, under the influence of temperate and mediterranean climate, with three bioclimatic belts (upper mesomediterranean, lower and upper mesotemperate). The vegetation study has been performed throught 121 phytosociological relevés. All data were submitted to multivariate statistical analysis. The phytosociological analysis allowed to describe woods, shrub vegetation and grasslands in terms of phytosociological units (syntaxa). On the whole 15 syntaxa - 6 of which forest syntaxa, 6 of shrub vegetation and 3 of grasslands - were recognized. The study of the dynamic relationships among the plant communities allowed to define the vegetation series. The correlation among vegetation series and geological, geomorphological and bioclimatic characteristics of the territory allowed to describe the plant landscape units (geosigmeta) of the study area.
