A fragmented forest, historically divided into the B³udowska, Knyszyñ, Malawicka, Odelska and Supral forests, with numerous seepages, springs (c.450), clean streams and small rivers. The terrain is varied. River valleys, mainly drained, are occupied by fens and transitional mires covered by reedbeds Phragmites and sedge-beds Carex. In stagnant hollows there are transitional mires and, more rarely, raised bogs. Although many stands still have a natural character, most are rather young (40-70 years old). About 80% of the forest is coniferous, dominated by pine Pinus and spruce Picea. Broadleaved forest is dominated by lime Tilia and hornbeam Carpinus, with ash Fraxinus and alder Alnus in riverine habitats and birch Betula in marshy areas. Open areas are occupied by fields, meadows, pastures and human settlements.
A total of 154 species have been recorded, including 139 breeding. Breeding species of global conservation concern that do not meet IBA criteria: Haliaeetus albicilla (two pairs), Crex crex, Gallinago media.
