Open meadows of varying sizes spread out around the lagoons and marshes that are seasonally flooded. The meadows are dry during the warmer months and become a nesting habitat for rare species of birds like the collared pratincole (Glareola pratincola) and the little tern (Sterna albifrons).
Most of the meadows are totally or partially flooded during winter however and are accordingly considered to be an integral part of the wetlands. Vegetation varies in accordance with the unique soil characteristics, such as salinity content, the grazing regime and previous cultivations. Halophile species like the Salicornia sp. prevail wherever there are high salt concentrations and form an impressive crimson coloured vegetation mat during the autumn months.
