A predominantly intact, riverine poor fen. The vegetation is dominated by various species of sedge Carex, with some wet woodland. Part of the area is used for haymaking.
Key biodiversity
The density of Acrocephalus paludicola at this site is the highest known in Europe. Breeding species of global conservation concern that do not meet IBA criteria: Crex crex (frequent).
Pressure/threats to key biodiversity
The main threat is nutrient pollution by agricultural and industrial waste-water inflows which result from drainage and land `reclamation'. This is potentially reversible, at least in part. It is planned to create a protected area by joining this site to Sporovsky Zakaznik (see Sporovo, 014). Studies of species diversity and census-work have been carried out with financial support from the Michael Otto Foundation for Environmental Protection.
