Brief_description
The lower Bitou River, progressing from marsh and floodplain to tidal conditions in the lowest reaches. Includes excellent marsh habitat for rails and other secretive birds; Redchested Flufftail and Baillon's Crake may breed. Moorhen counts peak in winter although recorded numbers are decreasing; winter Dabchick counts are also decreasing. Important for foraging and roosting shorebirds, waterfowl and egrets. Good numbers of South African Shelduck and Yellowbilled Duck recorded in winter 1995; Avocet numbers are high in summer. Species numbers and total counts have decreased over the three years of the survey period. Critical threats include pollution from effluent, pesticides and fertilizers, and damage by livestock; also threatened by siltation, reed encroachment, and residential development.
