The Site includes the Dniester River delta, streams, floodplain lakes and part of the Dniester “liman” (estuary). Vegetation consists of floating vegetation, reed thickets and floodplain forest supporting various nationally threatened plant species. It is an important area for breeding, wintering and migrating birds; it supports more than one percent of the regional population of the whiskered tern (Chlidonias hybrida), and the great white pelican (Pelecanus onocrotalus) can be found. The Site supports 60 fish species and provides a migration route for the critically endangered sturgeons Huso huso and Acipenser stellatus. It supplies water for domestic use and agricultural irrigation and is an important waterway. Human activities include environmental education, recreation and fishing. Threats are invasive species and disruption of the water dynamics through construction of dykes and canals; the decreased river stream flow results in reduced water exchange and silting. The Site’s boundary was delineated more accurately in 2021, increasing the recorded area by almost 6,000 hectares.
