East Africa > Uganda > Bugoma Forest Reserve
Summary
- Eastern chimpanzees (Pan troglodytes schweinfurthii) are present in Bugoma Forest Reserve.
- The chimpanzee population size is unknown; the density in 2006 was 1.99 individuals per km².
- The chimpanzee population trend is unknown.
- The site has a total size of 400 km².
- Key threats to chimpanzees are hunting and clearing land for agriculture.
- Conservation activities have focused on providing clean water access and raising conservation awareness.

Table 2. Ape population estimates in Bugoma Forest Reserve
| Species | Year | Abundance estimate (95% CI) | Density estimate [ind./ km²] (95% CI) | Encounter rate (nests/km) | Area | Method | Source | Comments | A.P.E.S. database ID |
|---|---|---|---|---|---|---|---|---|---|
| Pan troglodytes schweinfurthii | 2006 | 1.99 | Bugoma Forest | Line transects (Distance) | Plumptre & Cox 2006 | Survey effort: 511.2 km |
Threats
Table 3. Threats to apes in Bugoma Forest Reserve
| Category | Specific threats | Threat level | Quantified severity | Description | Year of threat |
|---|---|---|---|---|---|
| 1. Residential & commercial development | Absent | ||||
| 2. Agriculture & aquaculture | 2.1 Annual & perennial non-timber crops | Present, but threat severity is unknown | Encroachment of forest habitat for farming affecting the boundaries (Hobaiter & Gruber pers. comm. 2020). Sugarcane companies are clearing land within the reserve (Lewton 2020). | Ongoing (2020) | |
| 3. Energy production & mining | Absent | ||||
| 4. Transportation & service corridors | 4.1 Roads & railroads | Present, but threat severity is unknown | Busy dirt road cuts through the main forest block and divides chimpanzees' (and other species') territory - danger from speeding vehicles (Hobaiter & Gruber pers. comm. 2020). | Ongoing (2020) | |
| 5. Biological resource use | 5.1 Hunting & collecting terrestrial animals | Present, but threat severity unknown | The whole forest is affected. | Snares placed for duiker and bush pigs also trap chimpanzees. Chimpanzees are also directly targeted by hunters (Hobaiter & Gruber pers. comm. 2020). | Ongoing (2020) |
| 5. Biological resource use | 5.3 Logging & wood harvesting | Present, but threat severity is unknown | The whole forest is affected. | Illegal logging is present throughout forest, in particular outside of the immediate research areas; includes chimpanzee feeding species. Trees illegally felled for charcoal burning and firewood, particularly around the boundaries (Hobaiter & Gruber pers. comm. 2020). | Ongoing (2020) |
| 6. Human intrusion & disturbance | Absent | ||||
| 7. Natural system modifications | Absent | ||||
| 8. Invasive & other problematic species, genes, diseases | 8.4 Problematic species/diseases of unknown origin | Present, but threat severity is unknown | The whole forest is affected. | Respiratory outbreaks. Other sites in Uganda have confirmed similar respiratory pathogens of human origin (Hobaiter & Gruber pers. comm. 2020). | Ongoing (2020) |
| 9. Pollution | Absent | ||||
| 10. Geological Events | Absent | ||||
| 11. Climate change & severe weather | 11.1 Habitat shifting & alteration | Present, but threat severity is unknown | The whole forest is affected. | Some evidence that there is decreasing fruiting in forest trees, perhaps impacted by increase in overnight temperature lows (Hobaiter & Gruber pers. comm. 2020). | Ongoing (2020) |
| 12. Other options | Absent |
Conservation activities
The Bugoma Primate Conservation Project was established in 2015, and works in collaboration with local communities surrounding the reserve on a number of conservation activities, including school classes, plastic waste recycling, and clean water programs.

Research activities
Following initial surveys in 2015, systematic habituation of chimpanzee communities started in 2016 and is ongoing. Several groups of Ugandan mangabey are already habituated. Systematic data collection on chimpanzee behaviour, forest tree phenology, illegal activities, rainfall, and temperature are collected by the Bugoma Primate Conservation Project.
