| Brief_description |
| A semi-permanent freshwater pan with dense submergents, emergent grasses and sedges, and beds of Typha and Phragmites. Greyheaded Gulls breed on an island; during the survey period very few were recorded in summer, and winter numbers were very low in 1993 and 1996. The only other species recorded in large numbers is Sacred Ibis, from winter 1994 through to winter 1995. Spurwinged Goose is almost exclusively of winter occurrence, numbers having apparently declined greatly since 1995. Recorded numbers of Purple Gallinule are consistently higher in winter; Moorhen and Redknobbed Coot counts are decreasing. Important threats include continuing industrial development encroaching on the shoreline, landfill on the pan perimeter, severe pollution from industrial effluent and solid waste, and unrestricted access. The count is conducted from three vantage points. Point A, from the balcony of Messrs Thembelihle Equipment. Point B, from the parking spot in the northeast. Point C, from the balcony of Messrs Zultrans. |
