Itombwe Nature Reserve
Central Africa > Democratic Republic of the Congo > Itombwe Nature Reserve
Summary
- Eastern chimpanzees (Pan troglodytes schweinfurthii) and Grauer's gorillas (Gorilla beringei graueri) are present in Itombwe Nature Reserve.
- In 2009 the estimated chimpanzee population was approximately 6,302 individuals; the gorilla population size is unknown.
- The great ape population trend is unknown.
- The site has a total size of 6,000 km².
- Key threats to great apes are illegal hunting and logging in connection to illegal mining operations by armed groups.
- Conservation activities have focused on anti-poaching patrols, monitoring with SMART, and sensitization campaigns.
Site characteristics
Itombwe Nature Reserve is situated in the southern part of the Maiko-Taina-Kahuzi-Biega landscape in the Democratic Republic of the Congo. The site consists of a large forest block in the Albertine Rift, an important area for great apes. Several peaks of the Itombwe Massif, where the reserve is located, rise above 3,000 m, the highest being Mt. Mohi at 3,475 m (BirdLife International 2020). Itombwe Nature Reserve is also an Endemic Bird Area, an Important Bird Area (563 species have been recorded), an Alliance for Zero Extinction site and a Key Biodiversity Area under the Eastern Afromontane Hotspot (Kujirakwinja et al. 2019). Notably, the Critically Endangered Grauer's gorilla is present at the site. Other mammals of conservation concern present at the site include eastern chimpanzees and forest elephants. At least 21 amphibian taxa have been recorded at the reserve above 1,500 m, most of which have a limited distribution and six are endemic (BirdLife International 2020).

Threats
Destruction and degradation of the forest followed by large-scale mining has been a key threat at Itombwe. The region has been impacted by armed conflict among refugees who fled the Rwandan genocide in 1994 (Kujirakwinja et al. 2019). Large numbers of people settled and converted the forest for agriculture and pasture land. The discovery of valuable minerals such as coltan and cassiterite exacerbated the situation, as armed groups in the region took control of various parts of the massif and fight for these resources (WWF).

Challenges
The Minister for the Environment in Kishasa declared that a reserve would be established in Itombwe Massif, and the gazettement of the reserve was written in October 2006. However, no boundaries were delimited in the gazettement document, and this created anger and confusion amongst the communities of the Itombwe Massif, as they had not been consulted about the reserve (Kujirakwinja et al. 2019). Approximately 675,800 people live in or around the Itombwe Reserve (Kujirakwinja et al. 2019). A long process of participatory mapping of the boundaries began in 2010 with Africapacity, Institut Congolais pour la Conservation de la Nature, WCS and WWF staff participating in consultations with each of 550 villages within and around the proposed boundary of the reserve (Kujirakwinja et al. 2019). This process was completed in 2014, and in 2016 the governor of South Kivu signed the official designation of the boundaries of Itombwe Natural Reserve (Kujirakwinja et al. 2019).
