Brief_description |
An IBA. The lower reaches and mouth of the Berg River, incorporating the open estuary, mudflats and lagoon, various saltpans, permanent marshes and riparian reedbeds, floodplains at Kruispad, Langrietvlei and Kersfontein, the Kliphoek River, and Doornfontein pan. A very important wetland system, with large concentrations of many waterbird species in summer and winter, with globally significant numbers of seven species, nationally significant numbers of six more, and large counts of White Pelican, cormorants, ibises, waterfowl, Blacksmith Plover, Avocet and terns. Saltpans are being enlarged at the expense of mud flats and reedbeds (Kliphoek). Other important threats include boating, water- skiing, dam construction (Kliphoek River), and gill net fishing; there is some pollution and hunting. |
