Central Africa > Democratic Republic of the Congo > Maiko National Park

Summary

Eastern chimpanzees (Pan troglodytes schweinfurthii) & Grauer's gorillas (Gorilla beringei graueri) are present in Maiko National Park.
The chimpanzee and gorilla population trends are decreasing.
The site has a total size of 10,830 km².
Civil conflict in the area and the rise of armed groups controlling mines have led to widespread poaching.
The Dian Fossey Gorilla Fund (DFGF) and Flora and Fauna International (FFI) have implemented community conservation projects near Maiko National Park.

Site characteristics

Located in eastern DRC, Maiko National Park is the only protected area that harbours Grauer’s gorilla alongside important populations of okapi, Congo peafowl and forest elephant (Maldonado et al. 2012).

Ape status

Based on the encounter rates of nests of the 2005 and 2014 surveys, both chimpanzee and gorilla populations at Maiko National Park declined by 95.24% and 99.52% respectively (Plumptre et al. 2015). However, due to security issues, the surveys conducted have been infrequent, and they only covered sections of the park. For a more accurate assessment on the status of great apes, a survey covering the entire area is needed (Plumptre et al. 2015).

Threats

In eastern DRC, the civil war gave rise to the formation of armed groups that controlled artisanal mines in the area. Armed groups and miners relied on hunting bushmeat. Gorillas are highly prized as bushmeat because of their large size and they are killed relatively easily since they move in groups on the ground. Insecurity and lack of law enforcement continue to be a concern; the presence of militia groups have made it very difficult to assess great ape populations at the site and protect them (Plumptre et al. 2016).

Category	Specific threats	Threat level	Quantified severity	Description	Year of threat
1. Residential & commercial development	1.1 Housing & urban areas	Present, but threat severity is unknown	Less than 0.2 inhabitants/km² (BirdLife International 2020)	Rebels, miners and poachers live in temporary or more permanent settlements in the park (BirdLife International 2020).	Unknown
2. Agriculture & aquaculture		Unknown
3. Energy production & mining	3.2 Mining & quarrying	Present, but threat severity unknown		Artisanal miners rely on bushmeat once they are deep in the forest; in addition, apes are also at risk from disease transmission from miners (Plumptre et al. 2015).	Ongoing (2015)
4. Transportation & service corridors		Unknown
5. Biological resource use	5.1 Hunting & collecting terrestrial animals	High		Hunting of gorillas in the southern part of the park has been recorded; outside of the park, a nearby population has been exterminated (Plumptre et al. 2015).	Ongoing (2015)
6. Human intrusion & disturbance		Unknown
7. Natural system modifications		Unknown
8. Invasive & other problematic species, genes, diseases		Unknown
9. Pollution		Unknown
10. Geological Events		Absent
11. Climate change & severe weather		Unknown
12. Other options		Unknown

Conservation activities

The Dian Fossey Gorilla Fund (DFGF) and Flora and Fauna International (FFI) established three community conservation projects near Maiko. DFGF works at Nkubu Conservation Area, which covers about 1,000 square kilometers between Maiko National Park and Kahuzi-Biega National Park, a second stronghold for Gauer's gorillas. On the western edge of Maiko, FFI works in two unofficially designated reserves; REGOLU, founded in 2004, and REGUMUKI, founded in 2007. Both sites are in the process of becoming officially recognized community forests, and they cover 500 and 1,000 square kilometers respectively (Fritts 2019).
