Flora of the Isle su Cardulinu (Southern Sardinia)

Abstract

The results of two years of collection in a small isle in the southern Sardinia are reported, consisting in a floristic list of 116 entities distributed in 96 genera and 41 families. The biological spectrum of this flora puts in evidence a typical Mediterranean environment, characterized by a marked summer dryness. The ratio: number of entities/surface of the studied site has been compared with that of other small southern Sardinian islands, resulting the highest value. This floristic aspect, as well as differences in the biological spectrum, is interpreted as the result of the presence in the area under study of a desultory link with the mainland, in form of a sandy isthmus. This seems important in breaking the biological balance of the small island.
