<!-- INSTRUCTIONS FOR UPLOADING SITE INFORMATION
 +
- Wiki pages contain information in paragraphs, tables, lists, and images.
 +
- Text and images are not restricted, and their formats can be chosen as desired.
 +
- Tables and lists are extracted as data, so the following restrictions apply to them:
 +
  1) Table structure cannot be changed.
 +
  2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
 +
  3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.

= Exposure to climate change impacts =
 
−
 
−
As part of a study on the exposure of African great ape sites to climate change impacts, Kiribou et al. (2024) extracted climate data and data on projected extreme climate impact events for the site. Climatological characteristics were derived from observation-based climate data provided by the Inter-Sectoral Impact Model Intercomparison Project ([www.isimip.org ISIMIP]). Parameters were calculated as the average across each 30-year period.
 
−
For future projections, two Representative Concentration Pathways (RCP) were used. RCP 2.6 is a scenario with strong mitigation measures in which global temperatures would likely rise below 2°C. RCP 6.0 is a scenario with medium emissions in which global temperatures would likely rise up to 3°C by 2100. For the number of days with heavy precipitation events, the 98th percentile of all precipitation days (>1mm/d) was calculated for the 1979-2013 reference period as a threshold for a heavy precipitation event. Then, for each year, the number of days above that threshold was derived. The figures on temperature and precipitation anomaly show the deviation from the mean temperature and mean precipitation for the 1979-2013 reference period. The estimated exposure to future extreme climate impact events (crop failure, drought, river flood, wildfire, tropical cyclone, and heatwave) is based on a published dataset by Lange et al. 2020 derived from ISIMIP2b data. The same global climate models and RCPs as described above were used. Within each 30-year period, the number of years with an extreme event and the average proportion of the site affected were calculated (Kiribou et al. 2024).

East Africa > Uganda > Bwindi Impenetrable National Park

Summary

Loading map...
  • Eastern chimpanzees (Pan troglodytes schweinfurthii) & mountain gorillas (Gorilla beringei beringei) are present in Bwindi Impenetrable National Park.
  • It has been estimated that 459 gorillas occur in the site; the chimpanzee population size is unknown.
  • The gorilla population trend is increasing.
  • The site has a total size of 321 km².
  • Key threats to great apes are linked to high human presence, which poses some risk of disturbance and disease transmission.
  • Conservation activities have focused on ecotourism programs and regularly monitoring the health of habituated gorillas.
  • The park is a UNESCO Natural World Heritage Site.

Site characteristics

Bwindi Impenetrable National Park is located in southwestern Uganda, on the edge of the Albertine Rift Valley. The area is one of Uganda's oldest and most biologically diverse rainforests, which dates back over 25,000 years (Uganda Wildlife Authority). Encompassing a series of steep ridges and valleys, Bwindi is the source of five major rivers, which flow into Lake Edward. The park is famous for being home to almost half of the world's mountain gorilla population (Uganda Wildlife Authority). The site is a designated Important Bird Area, with 347 bird species documented in the forest, including 23 endemic species to the Albertine Rift (BirdLife International 2020). Bwindi was gazetted as a National Park in 1991 and declared a (UNESCO Natural World Heritage Site) in 1994.

Area 321 km²
Coordinates -1.017254, 29.671192
Designation National Park
Habitat types Subtropical/tropical montane forest, subtropical/tropical moist lowland forest

IUCN habitat categories Site designations

Ape status

The park is home to one of the two subpopulations of mountain gorillas in the world, the Bwindi-Sarambwe subpopulation (Hickey et al. 2018). Increases in both the Virunga Massif and the Bwindi-Sarambwe subpopulations led to a change in the IUCN Red List classification from Critically Endangered to Endangered in 2018 (Hickey et al. 2018). In spite of this increase, the overall population size is still small.

Threats

Table 3. Threats to apes in Bwindi Impenetrable National Park

Category Specific threats Threat level Quantified severity Description Year of threat
1. Residential & commercial development Absent
2. Agriculture & aquaculture Absent
3. Energy production & mining Absent
4. Transportation & service corridors Absent
5. Biological resource use 5.1 Hunting & collecting terrestrial animals Low Poaching as a non-target species; e.g., as a result of infant gorilla trafficking, snares are set up for other animals. Retaliatory killings are rare. Habituated gorillas are more vulnerable to poachers (Hickey et al. 2018). Ongoing (2018)
6. Human intrusion & disturbance Present, but threat severity is unknown Human presence due to tourism, conservation and scientific work, camps for security forces, etc., all of which pose some risk of disturbance and disease transmission (Hickey et al. 2018). Ongoing (2018)
7. Natural system modifications Absent
8. Invasive & other problematic species, genes, diseases High Vulnerability to human pathogens, and outbreaks of respiratory virus diseases and gastrointestinal parasite infections (Hickey et al. 2018). Ongoing (2018)
9. Pollution Absent
10. Geological Events Absent
11. Climate change & severe weather 11.1 Habitat shifting & alteration Present, but threat severity is unknown Increased temperatures and modified rainfall patterns likely to cause changes in food availability and habitat quality (Hickey et al. 2018). Ongoing (2018)
12. Other options 12.1 Other threat Present, but threat severity is unknown Bwindi gorillas appear to crop-raid because of the availability of palatable foods at the edge of the park, not due to a lack of dietary items in the park (Hickey et al. 2018). Ongoing (2018)

IUCN Threats list

Conservation activities

The site is managed by the Uganda Wildlife Authority. The management of the site has developed ecotourism programs that support the livelihoods of local communities (UNESCO). Nine groups have been habituated for tourism; the first one was the Mubare gorilla group, since 1993. Conservation Through Public Health work on reducing human-gorilla conflicts in and around the park, and avoiding the transmission of diseases.
