Site characteristics
Virunga National Park is located in eastern Democratic Republic of Congo and comprises the most biologically diverse protected area on the continent (Virunga National Park n.d.). The national park was first established in 1925 as Albert National Park. In 1960, following the country's independence from Belgium, it was renamed Virunga National Park. In 1979 the site was designated as a UNESCO World Heritage Site (UNESCO 2021).The park is unique with its active chain of volcanoes and rich diversity of habitats. Its range contains an amalgamation of steppes, savannas and plains, marshlands, low altitude and afro-montane forest belts to unique afro-alpine vegetation and permanent glaciers and snow on Monts Rwenzori whose peaks reach in 5,000 m height (UNESCO). The park is home to 218 mammal species, 706 bird species, 109 reptile species and 78 amphibian species (Virunga National Park n.d.). It also serves as refuge to 22 primate species, including mountain gorillas (Gorilla beringei beringei), the eastern lowland or Grauer's gorilla (Gorilla beringei graueri) and the eastern chimpanzee (Pan troglodytes schweinfurthii). A third of the world's mountain gorilla population is found in the park. The density of biomass of wildlife is one of the highest on the earth Planet (27.6 ton/sq.km). Among the wide diversity of ungulates found at the site, certain rare species are found, such as the okapi (Okapi johnstoni), endemic to the Democratic Republic of the Congo, and the red forest duiker (Cephalophus rubidus), endemic to Monts Rwenzori (Virunga National Park n.d.). The site is a Key Biodiversity Area owing to its global importance to the planet’s overall health and wealth in biodiversity (Key Biodiversity Areas Partnership 2020).

Ape status
The last mountain gorilla census in DRC, Rwanda and Uganda in the Virunga massif was in 2016. The results showed a total of 266 gorillas found on the Congo side. From then until December 2021, the number of gorillas has increased to over 350 individuals (Shengeri, A.R., pers. comm. 2021). The chimpanzee population in the park is unknown. Eastern lowland, or Grauer’s gorillas, are extremely rare in the park; only six individuals are being monitored (Shengeri, A.R., pers. comm. 2021).

Threats
Ongoing security issues continue to present challenges for the management of the park, although the number of militia operating in the area has declined over the past few years (UNESCO 2021). Issues of encroachment and deforestation for charcoal production continue to have a severe impact on the integrity of the park; as of 2021, approximately 18.5% of the site is affected by encroachment (UNESCO 2021). The eruption of Mount Nyiragongo in May 2021 has further complicated the situation and compounded the COVID-19 crisis. Around 234,000 were displaced from the surrounding area, and houses, schools, and health centers were destroyed (UNICEF).
Table 3. Threats to apes in Virunga National Park
| Category | Specific threats | Threat level | Quantified severity | Description | Year of threat |
|---|---|---|---|---|---|
| 1. Residential & commercial development | 1.1 Housing & urban areas | High | New villages built in the park: Kasindi/Lubiriha and Kilorirwe (Shengeri, A.R., pers. comm. 2021). | Ongoing (2021) | |
| 2. Agriculture & aquaculture | 2.1 Annual & perennial non-timber crops | Low | Land conversion for agriculture | Ongoing (2021) | |
| 2.3 Livestock farming & ranching | Low | Livestock farming / grazing of domesticated animals (UNESCO 2021). | Ongoing (2021) | ||
| 3. Energy production & mining | 3.1 Oil & gas drilling | Low | Concerns over potential oil exploitation and exploration (UNESCO 2021). | Ongoing (2021) | |
| 4. Transportation & service corridors | 4.1 Roads & railroads | Present, but threat severity unknown | Different roads across the park are present in Virunga National park, e.g., between Mutwanga- Beni-Karuruma-Kambo-Ishasha-Nyakakoma-Rutshuru-Kanyabayonga (Shengeri, A.R., pers. comm. 2021). | Ongoing (2021) | |
| 5. Biological resource use | 5.1 Hunting & collecting terrestrial animals | High | Poaching by armed groups (UNESCO 2021). Many poachers are arrested by rangers during patrols in the park. Most of them are sent to the court and are jailed. In addition, many traps and illegal hunting camps are destroyed by rangers during patrols (Shengeri, A.R., pers. comm. 2021). | Ongoing (2021) | |
| 5.3 Logging & wood harvesting | High | Deforestation for charcoal production | Ongoing (2021) | ||
| 5.4 Fishing & harvesting aquatic resources | High | Fisherman villages around Lake Edward have increased and occupy many hectares of the park (Shengeri, A.R., pers. comm. 2021). | Ongoing (2021) | ||
| 6. Human intrusion & disturbance | 6.2 War, civil unrest & military exercises | High | Civil unrest stemming from two civil wars and the illegal extraction of natural resources in the park, from which armed groups (e.g., ADF/NALU, FDLR, Mai Mai) continue to make revenue. Over 200 park rangers have been killed in the line of duty (Virunga National Park). | Ongoing (2021) | |
| 7. Natural system modifications | Unknown | ||||
| 8. Invasive & other problematic species, genes, diseases | 8.5 Viral/prion-induced diseases | Low | Risk of acquiring human pathogens, particularly respiratory diseases. Respiratory illness is the second most common cause of morbidity and mortality in habituated mountain gorillas, with outbreaks that occur annually and often cause group-wide morbidity (Gilardi et al. 2021). | Ongoing (2021) | |
| 9. Pollution | 9.4 Garbage & solid waste | Low | Trash observed near fishing villages around Lake Edward. In addition, poachers sometimes mix poison with water (Shengeri, A.R., pers. comm. 2021). | Ongoing (2021) | |
| 10. Geological Events | 10.1 Volcanoes | Medium | The Nyiragongo and Nyamuragira volcanoes are active volcanoes in the park. Chimpanzees residing on the slopes of Nyamuragira were threatened by the eruptions of January 2010. In addition to the impacts of mortality and further habitat loss, the eruptions reduce the chimpanzees’ ability to survive in a region where human development around the volcanoes prevents migration to other areas (Maldonado et al. 2012). | Ongoing (2021) | |
| 11. Climate change & severe weather | Unknown | ||||
| 12. Other options | Absent |
Conservation activities
In 2011, the Congolese National Parks Authority, (Institut Congolais pour la Conservation de la Nature, ICCN), and the Virunga Foundation (then known as the Africa Conservation Foundation), entered into a partnership to manage the national park. The Virunga Alliance was then created with the support from the EU. The Virunga Alliance is a development program that aims to end illegal and destructive resource extraction in the region by addressing the direct causes of poverty and conflict. The program was established to create more than 100,000 jobs to draw people out of armed militia groups and into work that fosters peacebuilding. The program is focused on tourism, sustainable energy, and agriculture (Virunga Alliance). The park is part of the Greater Virunga Landscape (GVL), a transboundary collaboration between DRC, Rwanda, and Uganda to conserve the landscape. Four sites have been chosen for monitoring and for tourism: the Mikeno sector, with 226 habituated mountain gorillas; Tshabirimu, with 6 eastern lowland gorillas; Tongo, with 28 chimpanzees, where habituation started in 1991; and Rumangabo, the headquarters of the park, where 18 chimpanzees have been habituated since 2015 and tourists can observe while visiting the station (Shengeri, A.R., pers. comm. 2021). Four main conservation pillars were established in 2010 with the Virunga Foundation in cooperation with the DRC government to protect the Virunga National Park: 1.Conservation: fight against poachers and destruction of the ecosystem of the park. The protection of highly important ecological corridors connecting different sectors of the park through regular ranger patrols is one of the main activities. 2.Tourism: development of tourism infrastructures. 3. Protection of Lake Edward against poachers and eviction of all squatters who take young fish. 4. Hydroelectric power plant construction around Virunga National Park which allows the local communities to develop their economy.

Challenges
The main challenges to ape conservation at the park include lack of security due to different rebel groups in the region. In 1986 when Uganda rebels ADF/NALU crossed into DRC and remained in the park around the Rwenzori massif (North sector), where many chimpanzees were present. In 1994 millions of refugees and defeated militaries crossed the border and settled around the Mikeno Sector, home to mountain gorillas. Since then, rebels continue to kill animals, rangers, cut trees for commercial charcoal, kidnap local people, and are involved in other criminal activities (Shengeri, A.R., pers. comm. 2021).
