La vegetazione del Parco Regionale Marturanum (Lazio settentrionale, Italia entrale): lineamenti fitosociologici e genesi del paesaggio vegetale

Abstract

The Marturanum Regional Park is a small protected area (1,240 hectares), however it is placed along the interface between two of the main lithological units of Lazio, hence featuring a high diversity of flora, vegetation and landscape. Further, it includes a small part of theMonti dellaTolfa, a 30,000 hectares hilly rangewhich features an exceptionally low population density. The Tolfa hills are a biodiversity hotspot of C-Italy and show a very distinctive landscape pattern. The present paper outlines a phytosociological classification and syntaxonomical discussion of the numerous plant communities found in theMarturanumPark.The presentwork describes also the different role of the natural constraints and of the historical and cultural processes that have led to the peculiar landscape patterns nowadays found in the area, and in particular to the differentiation between the two landscape systems of the pyroclastic flow and the Tolfa flysch.
