• Bonobos (Pan paniscus) are present in the Northern block (Maringa-Lopori-Wamba).
• It has been estimated that a minimum of 5,000 individuals occur in the site.
• The population trend is unknown.
• The site has a total size of 74,000 km².
• Key threats to bonobos are poaching, habitat destruction and degradation, risk of disease transmission.
• Conservation activities have focused on land-use planning.

Site characteristics

The site consists of a block of forest corresponding approximately to the Maringa-Lopori-Wamba landscape delineated by the Congo Basin Forest Partnership and the Commission des Forêts d’Afrique Centrale (IUCN & ICCN 2012). The landscape is situated in the Maringa and Lopori river basins in the Equateur Province, Democratic Republic of the Congo. Approximately 67% of the site is covered by forest, with swamps covering an additional 26%. The remaining area is a young secondary forest and rural complex (IUCN & ICCN 2012). The block contains four areas offering various levels of protection: Lomako-Yokokala Faunal Reserve, Luo Scientific Reserve, Kokolopori Bonobo Reserve, and Iyondji Community Bonobo Reserve (IUCN & ICCN 2012).

Ape status

Through analysis of all available data from surveys conducted between 2003–2010, it has been estimated that there is a minimum population of 5,000 individuals in the Maringa-Lopori-Wamba block, making it an important stronghold for bonobos (IUCN & ICCN 2012).

Threats

The main threats to bonobos in the forest block are poaching, habitat loss, and the risk of disease transmission. The area is far from urban centres and experiences high levels of poverty and reliance on natural resources obtained through slash-and-burn agriculture, fishing, and hunting (IUCN & ICCN 2012).

IUCN Threats list

Conservation activities

Since 2006, a major participative land-use planning exercise has been conducted, covering about 70% of the landscape (IUCN & ICCN 2012). This work has designated a mosaic of protected areas, community-based natural resource management areas, sylvo-agro-pastoral zones and logging concessions, with the objective of maintaining forest cover and forest connectivity (IUCN & ICCN 2012).
