Brief_description
One large and four small maturation ponds with short-grassed banks, some reedbeds, thick fringing vegetation, and trees which held a roost of Little Bittern, Greenbacked Heron, large herons, egrets, ibises, cormorants, etc. Formerly provided varied habitat for a wide range of waterbirds but habitat allowed to degenerate recently: ponds have not been cleaned and have become covered with invasive Salvinia molesta; most fish have probably died; thick fringing reeds and bush have been cleared, and roost trees were removed. A very sharp drop in the total count occurred after summer 1993; since then total counts and species numbers have continued to decline. Counts show a summer peak of cormorants, most waterfowl, and Moorhen and Red- knobbed Coot; African Jacana is resident and White Pelicans have occurred in summer. Small numbers of waders frequent the pond edges, shallow water and grassy banks. Lesser Jacana has been recorded. Two ponds have been cleared of Salvinia so conditions may improve.
