Brief_description
IBA and Ramsar site. Coastal lakes, most with little fringing vegetation, in grassland and marsh. Summer and winter counts of individual species show considerable fluctuations, but there seems to be a trend of decreasing numbers and species variety in both seasons. Influx of Cape Cormorant recorded in winter 1994; high counts of Reed Cormorant in winter 1992 and of Whitefaced Duck in winters of 1992 and 1993. Good numbers of Knot for this coast. 20-50 pairs of Pygmy Goose breed, as do 3+ pairs of Pel's Fishing Owl. Whitebacked Night Heron, Rufousbellied Heron, Lesser Gallinule, African Finfoot and Grass Owl occur. Threats include sedimentation, eutrophication and afforestation. Human pressure is increasing; the lakes are traditional fishing areas and are used for tourism and recreation.
