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.
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 favours the existence of a variety of animal species.
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.
