Katonga Wildlife Reserve with an area of 207 square kilometers was gazetted in 1964 as a game reserve, to serve as a corridor for migrating wildlife from Western Uganda to Tanzania and Sudan. It became a Wildlife Reserve in 1996 when the former Game Department and Uganda National Parks merged to form Uganda Wildlife Authority (Uganda World Authority). Currently, the reserve is managed by Uganda World Authority under the Kibale Conservation Area administration with a Warden In-Charge based at the Reserve Head Office at Kikorogoto.

Location and access
The 207km2 Katonga Wildlife Reserve is a savannah grassland ecosystem located within Kyenjojo and Kamwenge Districts. The journey into the Reserve is a three-hour drive from Kampala to Kyegegwa Town Council. At Kyegegwa, detour southwards for 42 km following well visible signposts.

Flora
The Reserve’s terrain is predominantly undulating in nature with distinct vegetation types. Vegetation includes grasslands, wooded grasslands, woodlands, riverine woodlands, swamp, riverine grasslands, papyrus. Most of the area is mixed savannah with acacia or woodland. However, large portions of the reserve are either permanent or seasonal wetlands. The reserve also contains various pockets of riverine and tropical forests. Its unique geographical location between forests, swamps, and savannah vegetation gives the reserve a diverse ecosystem that favors the existence of a variety of animal species. The most dominant plant species include Sporobolus Festivus and Chloris gayana. These species exist with associate species like Setaria species, Hyparrhenia species, and occasional Panicum maximum. The Katonga wetland system is interlinked with the Nile system forming an important wetland system for human survival. The variety of different vegetation types, particularly the wetlands, provides a range of habitats, which enhances the faunal diversity of the reserve.

Fauna
Katonga Wildlife Reserve has a viable Sitatunga population inhabiting the Katonga Wetland System. The reserve also harbors a high population of waterbucks. The population of Hippos and birds is also growing in addition to primates.

In the 1960s, the reserve was home to a variety of animals including the zebra, topi, and eland, which are no longer seen in the reserve. Elephant, buffalo, waterbuck, bushbuck, reedbuck, and sitatunga still occur in the reserve. Between 1971 and 1985, most of the wildlife was killed through commercial and subsistence poaching. The reserve was also heavily encroached by cultivators and cattle grazing. In 2014 however, all the encroachers in the park were evicted.

In 2015 60 Impalas and 5 Zebras were successfully translocated to the reserve in order to restock and boost animal populations for tourism. The population of impalas now stands at 300 individuals The current bird checklist is over 150 including species-specific to wetlands, savannah, and forests. Other mammals include Black and White Colobus Monkey, the River Otter, and Olive Baboon, Uganda Kob, Waterbuck, Leopard, Buffalo, reedbuck, bushbuck and duiker, and chevrotain. The reserve is also home to various reptiles, amphibians, and butterflies. The table below shows the 2004 animal population census results for the reserve.
