Site description
A wetland complex with lagoons, saltpans (`Other' land-use, below), extensive saltmarshes, freshwater marshes, sandbanks, and a remnant area of alluvial forest.

Key biodiversity
This is an important site for breeding, passage and wintering waterbirds and raptors. Species of global conservation concern that do not meet IBA criteria: Phalacrocorax pygmeus (wintering), Pelecanus crispus (10 wintering individuals), Aythya nyroca (passage), Haliaeetus albicilla (wintering), Aegypius monachus (wintering), Aquila clanga (wintering), Aquila heliaca (2 resident individuals), Gallinago media (passage). The site holds 20,000 or more waterbirds in winter, on a regular basis (including Anas penelope 10,000; Anas crecca 3,000; Anas clypeata 3,000; Fulica atra 15,500).

Pressure/threats to key biodiversity
The main threat to the site is from intensive agriculture and associated drainage and water management schemes. The completed diversion of the Evinas river and the current project to divert the Acheloos river are also major threats. Part of the area is a candidate SAC.
