Lower Dniester National Nature Park covers a large portion of the Dniester River Estuary where it enters the Black Sea in southwestern Ukraine. The floodplains and waterways are important to nesting and wintering waterfowl. They are also important for spawning fish: over 70 species of fish in 20 groups are recorded in the park. The boundaries include two Ramsar wetland sites of international importance. The park is about 30 km west of the city of Odessa, in the administrative districts of Bilhorod-Dnistrovskyi, Bilyayivka, and Ovidiopol in Odessa Oblast.
