Site details


Site description: The site is located in the south-east of the country, south-east of Kigali, and includes swamps and marshes in part of the flood-plain of the Nyabarongo river, the longest river in Rwanda. The vegetation is composed of Cladium and Typha spp., Cyperus latifolius, C. papyrus and Echninochloa pyramidalis. Average annual rainfall is estimated to be 950–1,100 mm.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas).
Additional biodiversity: See Box and Table 3 for key species. Around 50 species have been recorded from the wetlands, including Ardeola idae and Circus macrourus. In addition, three species of the Afrotropical Highlands biome (A07) have been reported (Table 3). Non-bird biodiversity: None known to BirdLife International.
