The Site is a system of small, interconnected floodplain lakes set in the lower Danube basin. Vegetation consists of emergent and submergent plant communities with numerous rare and protected species. The Site is important for migrating, breeding, and moulting birds; it supports internationally important numbers of white-fronted goose (Anser albifrons) and mute swan (Cygnus olor). There are important breeding and nursery habitats for fish and amphibians, and the European otter (Lutra lutra) and the endangered European mink (Mustela lutreola) can also be found. Human activities include conservation education, recreation, livestock grazing, haymaking and commercial fisheries. Lake Kartal is used as a reservoir, and fluctuations of the water level often lead to changes in the ecological capacity and quality of habitats. Since the last update in 1998, 100 hectares of meadow habitat and the connection between Kartal Lake and the neighbouring Kugurlui Lake (Ramsar Site no.760) have been restored. The Site’s boundary was extended and delineated more accurately in 2021, increasing the area by over 1,600 hectares.
