Nabajjuzi Wetland System. 15/09/06; Masaka, Sembabule, Mpigi; 1,753 ha; 00°46'S 031°41'E. Important Bird Area. A long narrow stretch of swamp from the periphery of Masaka to the major Katonga River system. It provides a spawning ground for mudfish and lungfish, and supports globally threatened bird species and the endangered Sitatunga. The site lies in traditional Buddu county of Buganda Kingdom, and some of the flora and fauna are closely associated with cultural norms and traditions, especially the totems. There is thus considerable cultural attachment of the surrounding areas to the wetland, which also plays an important role in stabilizing the banks of River Nabajjuzi, groundwater recharge, flood control and as a natural filter for silt and sediments in the runoff. The wetland is the source of water supply for nearby townships and provides fish, clay, papyrus, medicine and game meat (Sitatunga). Over the past 20 years there has been increased commercialisation of the resource products and some of the surrounding areas have been built up into trading centres and small towns, causing increased demand for resources. Water pollution from a tannery adjacent to the wetland is a big threat. The Wetlands Inspection Division and NGOs such as NatureUganda are implementing conservation and ecotourism activities. Ramsar site no. 1639. Most recent RIS information: 2006.
