13 Upper Biebrza catchment PL

Located in the Podlaskie Voivodeship in north-eastern Poland, the Upper Biebrza region within the Biebrza National Park is characterised by its valuable and relatively untouched wetland ecosystems. These include alkaline fens, transitional peatlands, and bog woodlands. The peat soils prevalent in this area, combined with a largely unaltered hydrological system, contribute to its significant water retention and carbon storage capacity.
