The marshy valley of the Grzybnica and Wo³czenica rivers, containing numerous channels. There are considerable areas of fen with large stretches covered with reedbeds Phragmites and wet, flooded meadows; bushes of alder Alnus are abundant. Land-uses include cattle-farming.
A total of 151 species have been recorded, 107 as breeders.
Pressure/threats to key biodiversity
Effluent from cattle-farming is a threat. In 1993 part of the marshes were altered by reedbed planting, damaging the habitat for breeding Acrocephalus paludicola (immediately before the damage there were 40-60 singing males). New roads are making access to the marshes easier for anglers and poachers.
