Brief_description
Ramsar site and IBA. The De Mond State Forest/Heuningnes River Estuary is one of the few breeding sites for the globally near-threatened Damara Tern (total population c. 14450 birds): 5-7 breeding pairs of this African endemic species are recorded. Heuningnes is the most southerly estuary in Africa. Its dune areas and pebble slacks are important nesting sites for birds; it also has breeding African Black Oystercatchers, Caspian Terns and Kelp Gulls. Biomass and total count graphs reflect large numbers of small shorebirds in summer and smaller numbers of large birds in winter. Critical threats include oil pollution and dam building; it is also threatened by human encroachment and chemical pollution.
