Brief_description
IBA and Ramsar site, important for bird breeding and migration stopover. A delta-type river mouth with a braided channel during low flow months. Has sandbars, tidal basin, narrow floodplain, marshes (Phragmites, Scirpus, Sporobolus, Sarcocornia), pans, and a saltmarsh on one bank of the river mouth. Two counts (summer and winter 1997) are available, recording a large variety of waterbirds, including globally significant counts of Kelp and Hartlaub's Gulls, and nationally significant numbers of South African Shelduck and Cape Shoveller. Large numbers of Cape Teal, Avocet, Whitefronted, Chestnutbanded, Kittlitz's and Blacksmith Plovers, and Cape Wagtail, recorded; also good numbers of White Pelican and both flamingos. A severe threat is degradation of the salt marsh through mining; important threats are hunting/poaching, boating, fishing, livestock grazing/trampling, and siltation. Count is done from the Mouth up to the Sir Ernst Oppenheimer Bridge.
