The site contains the estuary of the Sperchios river, an area of extensive saltmarshes and reedbeds (Phragmites). Along the river is a mosaic of riverine forest, wet grassland and freshwater marsh.
This is an important area for species characteristic of riverine forest, reedbed and open water. Species of global conservation concern that do not meet IBA criteria: Phalacrocorax pygmeus (passage, wintering), Aquila clanga (wintering), Falco naumanni (breeding). The site regularly holds 20,000 or more waterbirds in winter (including Anas crecca 4,250; Recurvirostra avosetta 1,310).
