Kyambura Game Reserve, Primate reserve in Queen Elizabeth National Park, Uganda

Kyambura Game Reserve is a 156 sq km protected area on the north-eastern side of Queen Elizabeth National Park, about 30 km from park headquarters. Its rolling savanna grassland is cut by the 16 km Kyambura Gorge, which holds thick riverine forest and the Kyambura River and links to the Kazinga Channel. The reserve also adjoins Maramagambo Forest and Kigezi Game Reserve within the Queen Elizabeth Protected Area.

The reserve started as a controlled hunting area in 1962 before being officially protected as a game reserve in 1965. Settlers were removed from the land during the 1990s to restore it as a dedicated wildlife sanctuary.

The reserve is a buffer zone for Queen Elizabeth National Park, and its chimpanzees became isolated when forests linking the gorge to Kalinzu and Maramagambo were cleared. Visitors tracking them see the gorge's "underground forest", along with red-tailed monkeys, black-and-white colobus, baboons and vervet monkeys.

Kyambura Gorge runs about 11 km and links to the Kazinga Channel, which forms the reserve's northern boundary; the gorge itself is described as 16 km long. The reserve lies on the north-eastern side of Queen Elizabeth National Park, roughly 30 km from its headquarters, with villages and plantations to the south. Chimpanzee tracking means descending into the gorge's riverine forest, the only place in the Queen Elizabeth Protected Area where habituated chimpanzees are seen.

The chimpanzees in Kyambura Gorge became isolated after forests linking it to Kalinzu and Maramagambo were cleared, and conservationists worry this could lead to inbreeding and mutations. Tracking them also gives visitors views of the gorge's "underground forest" and its birds and smaller primates.
