The site comprises two freshwater lakes and a gorge. Lake Koronia is shallow, eutrophic and polluted. Lake Volvi is deeper and overflows through the Rentina gorge. The gorge is dominated by maquis and riverine scrub.
This site is important for passage and wintering waterbirds. Species of global conservation concern that do not meet IBA criteria: Aythya nyroca (minimum 43 wintering individuals), Oxyura leucocephala (wintering), Haliaeetus albicilla (wintering), Falco naumanni (passage). The site holds 20,000 or more waterbirds, on a regular basis (including Podiceps cristatus 6,729; Aythya ferina 8,029; Aythya fuligula 1,361; Fulica atra 12,736).
Pressure/threats to key biodiversity
Declining water-levels and water pollution, from agricultural and industrial sources, are a severe threat. A pollution incident in 1995 left thousands of waterbirds dead. In the gorge, fire is a serious problem and has previously caused severe damage. Part of the area is a candidate SAC.
