Huge lake of international importance located on the Russian--Estonian border, in a highly developed area.
Wetland of International Importance. Not less than 200000-300000 individuals of waterfowl stopover during spring migration. Important place for moulting waterfowl, notably Anas platyrhynchos, Aythya ferina, Aythya fuligula and Bucephala clangula. The narrow land-corridor between Chudskoe and Pskovskoe lakes acts as a major bottleneck for migrating birds: as many as 4 million (mainly passerines but also some raptors) have been estimated to pass in a single 5-hour period in early September.
Conservation responses/actions for key biodiversity
It is questioned whether this area should be treated as one IBA or whether several IBAs along the Estonian and Russian shores should be identified. More field research is needed and is already planned.
