Brief_description
Includes 11 small dams and pans of the Johannesburg Northern Sewage Works. Diepsloot is a sewage farm with cattle pastures, maize and large reedbeds. Waterbirds are numerous and varied, with peak numbers of cormorants, Darter, egrets, Sacred and Glossy Ibises, and most shorebirds, occurring in summer, and of Dabchick, Hadeda, Southern Pochard, Spurwinged Goose, Red- knobbed Coot and Wattled Plover in winter; Egyptian Goose is common all year. There were exceptionally high winter counts of Whitefaced Duck in 1994 and of Yellowbilled Duck in 1996 and 1997. Little Bittern, Redchested Flufftail, Black Crake and Purple Gallinule occur. There appears to be an overall decline in species numbers and winter count totals. Threats include cattle grazing / trampling, informal housing, and poaching.
