Brief_description
Large dam; some fringing marshy vegetation; some habitat for shorebirds at low water levels. Globally significant numbers of Darter, and nationally significant numbers of African Spoonbill and Egyptian Goose, recorded. Spurwinged Goose, Redknobbed Coot and Blacksmith Plover normally more numerous in summer, Redbilled Teal and Southern Pochard in winter; Yellowbilled Duck common all year. Good numbers of Purple Heron and African Black Duck. Dead trees in dam are falling down, resulting in fewer nesting sites for cormorants, herons, egrets, African Spoonbill and Sacred Ibis: all these species commoner in summer, but counts of some are declining. Total count and biomass declining in summer, when counts of species such as Egyptian Goose and Blacksmith Plover are falling. Recreational activities are an important threat; pollution by domestic sewage and solid waste is a mild threat.
