The Reserve consists of the shallow and moderately eutrophic Lake Łuknajno and its surrounding habitats. The Lake’s shoreline is densely covered with abundant vegetation. The other habitats in the Site are mainly reed and sedge beds, willow communities and alder carr. The Reserve supports numerous species of breeding and wintering birds, with the Lake providing food to great crested grebe Podiceps cristatus, mute swan Cygnus olor and several ducks, among other species. The field station of the Warsaw University Zoological Institute, which is in the Site, promotes research and organizes educational activities. The main threats are eutrophication caused by nutrient runoff from nearby fields, and predation by invasive American mink (Neovison vison). As of 2019, a management plan was being prepared.
