The site is a complex of calcareous marshesGotówka, Brzeno, B³ota Serebryjskie, Rozkosz and Stefanówsituated north-west and west of Che³m town. Fens overlie the chalk, and are dominated by great fen sedge Cladium. Wetter areas are covered by beds of reed Phragmites and sedge Carex. Within the marshes are chalk islands covered with dry grassland and scrub. Surrounding meadows are used by farmers. Most of the marshes are cut by old but still functioning drainage channels which join the Udal river system (the Bug tributary), the wier¿owski canal system and the Gdolanka river system (the Uherka tributary).
Breeding species of global conservation concern that do not meet IBA criteria: Crex crex (six pairs), Gallinago media (16 displaying males).
Pressure/threats to key biodiversity
In the immediate proximity of Che³m, the cement-works and busy transportation network pose a considerable threat to the marshes. Another threat is infrastructural development associated with a motorway-construction program linking Che³m with the border-crossing at Dorohusk. Only one marsh lies fully within a protected area (Bagno Serebryskie Nature Reserve). There are plans to enlarge the other reserves that partially cover other marshes (Brzeno and Roskosz). OTOP and IUCN-WCU are carrying out a project to protect and rehabilitate the marshes.
