The Kalinzu Forest (137 km2) is one of the Central Forest Reserves managed by the National Forestry Authority of the Republic of Uganda. Together with the adjacent Maramagambo Forest (443 km2) and Kashoha-Kitomi Forest (399km2), it constitutes the largest remaining forest block in Uganda. The central African forest belt extends eastward to the edge of the Rift Valley, and Kalinzu Forest lies along this boundary. Kalinzu Forest receives approximately 1,500 mm of rainfall annually. Despite this relatively low precipitation, it supports a medium-altitude evergreen forest and represents the easternmost extent of Africa's forest belt.
Kalinzu Forest is now an isolated block, surrounded by extensive farmland to the east and tea plantations to the south. Due to its proximity to local communities, the forest is used in various ways—both legally and illegally. The National Forestry Authority permits limited use, such as firewood collection on specific days and in designated zones, as well as the gathering of medicinal plants and materials for handicrafts. However, the forest also suffers from illegal selective logging, charcoal burning, alluvial gold extraction, and hunting using traps and dogs
