Brief_description
An open estuary with mud, sandbanks, and some patches of reeds, sedges and grass. A good site for concentrations of shorebirds and terns; the relatively high counts in summer reflect the abundance of these migratory species. Nationally significant numbers of Greyheaded Gull are recorded in summer; Kelp Gull is most numerous in winter. Relatively few waterfowl occur. Numbers of cormorants, ibises and Darter peak in winter; White Pelican is recorded only on summer counts, and Blacksmith Plover and Swift Tern are common in summer and winter. Woollynecked Stork, Whitefronted Plover, African Black Oystercatcher and Caspian Tern are recorded. Boating and water skiing are critical threats, while a severe threat is posed by industrial and domestic pollution; domestic dogs are also a problem.
