Biebrzanaki National Park is one of the largest and most well-preserved areas of natural swamps and peatlands in the Continental biogeographical region. It comprises several types of swamp, grass tussock communities, alder forest and some cultivated land. The Biebrza river that runs through the Site features a number of meanders and oxbows in various stages of succession, which provide a great variety of habitats. The area hosts a large number of rare, endemic and endangered species, including such rare taxa as the moth Catocala pacta, European fire-bellied toad, otter, musk rat, wolf and elk, for whom this variety of habitats is essential. Moreover, numerous migrating waterbirds use the wetland for feeding, resting, moulting and breeding. Flower meadows provide nourishment for breeding wild animals, and they support insects which also serve as pollinators of nearby crops. The area is also valuable for human populations, as in and around the Park there are over 600 kilometres of canoeing, cycling, running and walking trails and educational paths equipped with viewing towers, platforms and boardwalks. The local population also earns some additional income by gathering herbs and fruits. The area faces some increasing threats, which include dredging, canalization, water management and invasive alien species. A management plan is currently being prepared.
