Summary Despite the importance and the resouces that can be obtained form Nabajjuzzi, the wetland faces a lot of pressures. The pressures are in form of hunting of sitatunga and collection of Grey Crowned Crane eggs. Others are brick making, paddocking, bush burning, tree planting and cultivation which are mostly in Buwunga Sub County. Settlement, waste disposal, car washing and effluents from tannery factory are common threats. The conservation of the wetland and the education of the communities is highly encouraged.

Site description Nabajjuzi wetland lies south West of central Uganda in Masaka District (Lwabenge, Kyamulibwa, Kalungu, Mukungwe, Nyendo, Kimanya, Katwe, Kingo, Kibinge, Butenga and Bigasa sub-counties), Sembabule District (Mijwala sub-county) and Mpigi District (Kabulasoke sub-county). The system is a long narrow stretch of swamp that stretches up to the Kagera River basin area to the North and past the periphery of Masaka Town Municipal Council along Masaka – Mbarara highway to the South. Nabajjuzi is dominated by Cyperus papyrus with patches of Miscanthus violaceus in most parts. In the swamp interior are also communities of Kostchya sp., a common shrub in C. papyrus swamps. There are also small open water pools supporting Nymphaea nouchali var. caerulea. The swamp is also a source of fish, clay, papyrus and other crafts materials and game meat. The local community with the help of NatureUganda has initiated eco-tourism activities in the wetland

Notes: Nabajjuzi Wetland is important regionally and globally for conservation of vulnerable and threatened species of birds and other animals.

Other biodiversity Nabajjuzi Wetland supports globally threatened bird species and the endangered Sitatunga. It is also important as a spawning ground for mudfish (Clarias mossambicus) and lungfish (Protopterus aethiopicus). The Sitatunga (Tragelaphus spekei) (CITES App. III), an antelope that inhabits wetlands, currently though not threatened is coming under increasing pressure due to threats on its habitat.

Protection status Nabajjuzzi wetland was designated as a wetland of international importance in 2006. The Ramsar site covers an area of 2144 ha. This wetland is important because it hosts threatened species of birds, fish and mammals. It is also a major source of drinking water to Masaka town

Access/Land-Owner requests The Wetlands Management Department controls the extraction of resources. The access of resources are limited to domestic and non commercial purposes.
