Site description The site comprises nine large fish-ponds in the Fize° valley, created in areas of old marsh. Some ponds support reedbeds (Phragmites). The surrounding hills have grassland, arable fields and small woodlands. Human activities include angling and traditional grazing.

Key Biodiversity This is an important site for breeding and passage waterbirds. Wildfowl use the ponds for roosting. There are few wintering birds as the lakes usually freeze over. Species of global conservation concern that do not meet IBA criteria: Branta ruficollis (4 wintering birds), Aythya nyroca (10-36 passage birds).
