Geomorphology and plant landscape: the example of the great landslide Pescacci (Serra San Quirico - Central Apennines).
Herewith is presented a phytosociological detailed study of the vegetation of a pre-Apennines area in the Marche’s region, named Pescacci, in the town of Serra San Quirico (AN) affected by a large landslide known since the middle of the eighteenth century. The detailed historical geomorphological analysis allows to evaluate the changes that have occurred over time that have created a high diversity of habitats and microhabitats. The integrated analysis conducted confirm the close relationship between vegetation and geomorphology and the high value ofplant associations as ecological indicators.
We describes two new associations of plain and riparian vegetation, respectively known as: Salici apenninae-Fraxinetum oxycarpae and Rubo caesii-Populetum canescentis, vicarious in the pre-Apennines and infra-Apennines territories of the sub-Mediterranean associations already described.The phytosociological analysis of detail also made it possible to describe the new association Scabioso maritimae-Hedysaretum coronarii for the pioneer vegetation which occupies the landslide slopes, in addition to other new syntaxa. The identification of the dynamic relationships between the different plant communities found, made it possible to reconstruct the main vegetation series from which integration result the landscape vegetation units of the investigated area.
