摘要: Aim of the paper is to describe conservation state dune plant communities Lazio (central Italy), using both original and already published phytosociological releves. This case study in particular analyses effects human disturbance on species composition vegetation zonation coastal sandy landscape, classified three land facets. 13 associations were recognised 9 them identified as potential natural types for ecosystems Lazio. Incidence ruderal alien taxa calculated each community facet. The results have produced evidence that, even if coastline largely occupied by settlements or infrastructures, several sites still preserve an high diversity few inside habitats occur. On contrary where impact intense, disappear they are present, incomplete, ruderals abundant locally common. A data-base was realised a monitoring purpose.
