| Brief_description |
| A nature reserve. Seasonal saline vlei, usually dry March-June; open water and open shoreline, with little palustrine wetland habitat; largest numbers of foraging waterbirds occur when water level falling. Important breeding and moulting site for Cape Shoveller (globally significant numbers); important for breeding Great Crested Grebe (globally significant winter count in 1994) and Dabchick; Sacred Ibis, many waterfowl, Kittlitz's and Blacksmith Plovers, Moorhen, Redknobbed Coot and Hartlaub's Gull breed commonly. In summer, good numbers of Whitebreasted Cormorant, Greater Flamingo (in 1993), many waterfowl, and Palearctic shorebirds; high winter count of Swift Tern and Whitewinged Tern in 1995. Severe threats are pollution by fertilizers and encroachment by emergent plants; other threats include siltation, alien plant infestation in the catchment, and grazing. |
