Site description (2001 baseline)
Kusa swamp, at the mouth of River Nyando, is a wetland at the easternmost end of Lake Victoria’s Winam Gulf. Dense stands of papyrus Cyperus papyrus are fringed on the lakeward side by the water grass Vossia cuspidata and along the shore by reeds Phragmites spp.
Key biodiversity
See Box and Table 3 for key species. Kusa includes a substantial stand of papyrus, and the Near Threatened Laniarius mufumbiri is fairly abundant here. Other Lake Victoria Basin biome species include the papyrus endemics Bradypterus carpalis and Cisticola carruthersi, and it is suspected that Serinus koliensis and the globally threatened Chloropeta gracilirostris are likely to occur.
Non-bird biodiversity: Little information is available. The ungulate Tragelaphus spekii (LR/nt) occurs but is uncommon, and the snake Python sebae has been recorded. Like other wetlands around the shores of Lake Victoria, Kusa is probably an important refuge for a number of the lake’s endemic haplochromine fish species.
