Brief_description
In Pongolapoort Nature Reserve IBA. Large dam on Pongola River; deep water; steep shoreline. When water level was low, had a muddy/rocky shore, so more shorebird habitat; dam now full and shoreline flooded grass and trees, making visibility poor for counts - this may be responsible for recent decline in count totals (D. Johnson). Wide winter and/or summer fluctuations in numbers of some species; no consistent pattern. Whitebreasted Cormorant and Yellowbilled Stork have bred. Numbers of cormorant, ibis and most waterfowl peak in winter; most egrets, Fulvous Duck and Egyptian Goose commoner in summer. Good numbers of Blackheaded Heron and Blackwinged Stilt in winter. High biomass in winter 1995 due to Spurwinged Goose numbers. Threats are eutrophication from fertilizer runoff, and periodic dense growths of blue-green algae.
