Aquatic-coastal complex of Cape Opuk. 29/07/04; Crimean AR; 775 ha; 45°01'N 036°12'E. Nature Reserve. Combination of steep limestone rocks on the seaside (marine boundary lines along 6 meter isobath), sandy-coquina spits, and a salt lake. Thousands of birds winter in the wetland complex or stop during their migrations, especially the White-fronted Goose, Mallard, Garganey, and Coot. Threatened species such as the Eagle Aquila heliaca or the Bat Rhinolophus ferrumequinum occur within the area. Thickets of macrophytic algae provide a suitable habitat for protected species such as the Great Sturgeon and the Black Sea Salmon and constitute an important spawning ground for many other fish species. Dolphins and porpoises (Phocoena phocoena, Tursiops truncatus) are observed periodically. Environmental education activities and scientific researches are carried out annually. Ramsar site no. 1395.
