Brief_description
The open estuary of the Keurbooms River. Two summer and three winter counts indicate good numbers of cormorants (especially in winter), an apparently resident population of Purple Heron, reasonable numbers of Little Egret throughout the year, a good variety of shorebirds (including large concentrations of Grey Plover, Greenshank and Whimbrel) and significant roosts of Kelp Gull (particularly in summer) and Swift Tern. Dabchick have been counted only in the winter and counts are decreasing. Residential development is a critical threat, while boating, fishing, general human disturbance, domestic animals, and bank erosion are also listed as severe threats.
