Malebo
Summary
- Bonobos (Pan paniscus) are present in Malebo.
- It has been estimated that 39 (CI: 30-53) individuals occur in the site.
- The bonobo population trend is unknown.
- The site has a total size of 1044 km².
- Key threats to bonobos are hunting and habitat encroachment.
- Conservation activities have focused on habituation of bonobos for ecotourism, enforcing local taboos about bushmeat, and employing local villagers as bonobo trackers.
Site characteristics
The site is located in the Lake Tumba landscape in western Democratic Republic of Congo (DRC). The region is characterized as a forest-savanna ecosystem, with altitudes ranging from 300 to 700 m (Serckx et al. 2014). The types of forests found at the site include re-colonizing Uapaca sp., old secondary, mixed mature, old growth mono-dominant, riverine gallery and Marantaceae forests (Serckx et al. 2014).The region is also characterized by flood episodes during which water covers ca. 65% of the forest (Inogwabini et al. 2013).

| Designation | Unclassified |
| Habitat types | Subtropical/tropical moist lowland forest, subtropical/tropical swamp forest, savanna, subtropical/tropical heavily degraded former forest |
Ape status
In 2005, the presence of a bonobo population in the region was documented by the local NGO Mbou-Mon-Tour and by an extensive survey conducted by the WWF (Serckx et al. 2014). In 2007, a habituation program started. The bonobo population seems to be made up of two communities, inhabiting the Nkala and Mpelu forests (Serckx et al. 2014).

Threats
Bonobos are largely respected in the area, and local communities refrain from hunting or eating them, as they believe them to be their ancestors (Inogwabini et al. 2007). However, as other groups and logging companies have moved into the area, this taboo has become degraded; thus, hunting and agricultural expansion now threatens bonobos and other wildlife (SynchronicityEarth).

Conservation activities
WWF began working on bonobo conservation in the western part of the country in 2005. To protect the bonobos in this natural reserve, WWF has developed an ecotourism initiative called Picbou (Projet Intégré de Conservation des bonobos de l’ouest) since 2006. The project is implemented in collaboration with the local NGO Mbou-Mon-Tour (MMT). Three groups of bonobos have been habituated in the region to learn more about their socio-ecology and develop more effective conservation strategies. Simultaneously, the ecotourism project aims to bring income to the villagers in order to encourage them preserve their natural heritage (WWF 2017).
