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).
