The Site in the south-east of Corsica consists of four temporary pools and their catchments and two temporary streams, which are dominated by several types of scrub, rock rose, and spring grasses. The existence of the pools in an almost semi-arid granite landscape, rich in species adapted to extreme conditions, is a rare geomorphological phenomenon in the region. These environments are renowned for the presence of globally vulnerable plants such as antinoria (Antinoria insularis) and the endemic Corsican scilla (Prospero corsicum). The presence of plants of the classes Isoeto-littoreletea and Isoeto-nanojuncetea, which are now quite rare in Europe, contributes to a plant community of great interest. The pools support a great diversity of species of which most are rare and closely associated with this type of environment, including four amphibians that are nationally protected. The principal land use is the grazing of cattle and goats, though these seem to have declined since 2000. Fires remain a potential threat to the ecosystem.
