Brief_description |
Erratically flooded pans, with some reeds (mainly Phragmites). A good variety of waterbirds occurs. Large variations in counts of ducks, shorebirds and other species, in summer and winter, reflect variations in water levels due to area's uncertain and erratic rainfall; pans need heavy rain to flood, and most inflow is sheetwash from higher up valley. Formerly, water inflow after dry periods was followed by proliferation of small aquatic crustacea (Daphnia); numbers of ducks and shorebirds (especially Blackwinged Stilt) arrived to breed, the young apparently being dependent on the crustacean food supply (A.J. Tree). In 1995 a large population of fish-eating birds occurred after bream entered the system during the 1994-95 flood and bred prolifically. Great recent increases in Ruff numbers possibly associated with increase in Diptera following increased sewage inflow (A.J. Tree). A recent and severe threat is influx of sewage from nearby Ostrich farm paddocks, through which sheetwash flows; high concentrations of Daphnia no longer occur and breeding birds are much less numerous. |
