| Brief_description |
| Comprises an IBA with Redhouse and Chatty saltpans. Open estuary; little waterfowl habitat but good foraging and roosting site for shorebirds; large tern roost. Good winter counts of Cape Cormorant and Little Egret in 1994; other cormorants, and Sacred Ibis, African Spoonbill and Cape Teal, also normally peak in winter. Globally significant numbers of Kelp Gull, and nationally significant numbers of African Black Oystercatcher, highest in winter. In summer, high numbers of Palearctic shorebirds, especially Grey Plover, Turnstone, Terek and Curlew Sandpipers, Greenshank, Bartailed Godwit, Curlew and Whimbrel; also good winter counts of several of these species, and of Blackwinged Stilt and Whitefronted Plover. Roseate Tern recorded irregularly. Threats include sedimentation, reclamation, pollution (domestic sewage and solid waste), and overhead powerlines. She site is counted from the mouth to the navigational limit, excluding the top of some creeks. |
