abstract

Ruderal vegetation of Palatine’s archaeological area (Rome, Italy). The most significant types of the ruderal vegetation of Palatine’s archaeological site are described. The investigations have concerned the meadow communities, varying in relation to micro-environmental and anthropic factors as stamping, mechanical and chemical weed killing and irrigation. Different communities, either with therophytic character, ascribed to the Helianthemetea guttati, Thero-Brachypodietea, Stellarietea mediae and Polygono-Poetea annuae classes, or with hemicriptophytic character, belonging to the Artemisietea vulgaris and Parietarietea judaicae classes, are described through the phytosociological analysis. Some associations, such as Trifolio scabri-Hypochoeridetum achryrophori, Valerianello eriocarpae-Cerastietum glomeratiDauco-Picridetum hieracioidis, were not indicated for the urban area. The considerable floristic and coenological richness of site is emphasized, revaluing the important role of archaeological areas as a reserve of biodiversity.
