The Nkuba Conservation Area is situated in eastern Democratic Republic of the Congo (DRC), roughly halfway between Maiko National Park and Kahuzi-Biega National Park. The site is community-owned and managed by a collaboration between the Dian Fossey Gorilla Fund (DFGF) and local community stakeholders (DFGF 2020). The area is a biodiversity hotspot, providing habitat for at least eight threatened species of mammals, including eastern chimpanzees and Grauer's gorilla (DFGF 2020). The site also holds a wide diversity of birds, insects, plants and fungi. In April 2021, the DRC government officially recognized the community ownership of the three forest concessions that make up Nkuba Conservation Area (Starling 2021). | The Nkuba Conservation Area is situated in eastern Democratic Republic of the Congo (DRC), roughly halfway between Maiko National Park and Kahuzi-Biega National Park.

Poaching is a major threat at the site and in the region (Starling 2021, Maldonado et al. 2012 ). Hunting activities are linked to the civil unrest in the region and armed rebel groups who control artisanal mines and often poach gorillas (Starling 2021). Violence has left the local population in acute poverty, forcing them to hunt for bushmeat or work for mining operations that harvest minerals used to make electronics sold in the Global North (Starling 2021). | Poaching is a major threat at the site and in the region ([[#R01409|Starling 2021]], [[#R01408|Maldonado et al. 2012]] ).

Summary
- Eastern chimpanzees (Pan troglodytes schweinfurthii) & Grauer's gorillas (Gorilla beringei graueri) are present in Nkuba Conservation Area.
- It has been estimated that approximately 200 gorillas occur in the site.
- The great ape population trend is unknown.
- The site has a total size of 2,400 km².
- Poaching is a major threat at the site, fueled by civil conflict and illegal mining activities.
- Conservation activities, implemented by the Dian Fossey Gorilla Fund, have focused on sensitization and raising awareness, employing people from local communities, including ex-poachers, and improving local livelihoods.
Site characteristics
The Nkuba Conservation Area is situated in eastern Democratic Republic of the Congo (DRC), roughly halfway between Maiko National Park and Kahuzi-Biega National Park. The site is community-owned and managed by a collaboration between the Dian Fossey Gorilla Fund (DFGF) and local community stakeholders (DFGF 2020). The area is a biodiversity hotspot, providing habitat for at least eight threatened species of mammals, including eastern chimpanzees and Grauer's gorilla (DFGF 2020). The site also holds a wide diversity of birds, insects, plants and fungi. In April 2021, the DRC government officially recognized the community ownership of the three forest concessions that make up Nkuba Conservation Area (Starling 2021).

Ape status
Researchers at the DFGF estimate that about 200 Grauer's gorillas live within Nkuba. Nkuba makes up about 10% of the gorilla’s total habitat in DRC (Starling 2021).

Sampling methods Analytical frameworks
Threats
Poaching is a major threat at the site and in the region (Starling 2021, Maldonado et al. 2012 ). Hunting activities are linked to the civil unrest in the region and armed rebel groups who control artisanal mines and often poach gorillas (Starling 2021). Violence has left the local population in acute poverty, forcing them to hunt for bushmeat or work for mining operations that harvest minerals used to make electronics sold in the Global North (Starling 2021).

Research activities
A study by van der Valk et al. (2018) showed that Grauer’s gorilla populations have suffered decreased genetic diversity from habitat fragmentation, making Nkuba’s role as a wildlife corridor between Kahuzi-Biega and Maiko crucial. Furthermore, another study found that Nkuba’s gorillas were more genetically diverse than populations living at the edges of its habitat range, highlighting the importance of Nkuba for forest connectivity (Baas et al. 2018).
