Central Africa > Democratic Republic of the Congo > Luo Scientific Reserve
Summary
- Bonobos (Pan paniscus) are present in Luo Scientific Reserve.
- It has been estimated that 173 to 231 individuals occur in the site.
- The bonobo population trend is decreasing.
- The site has a total size of 481 km².
- Key threats to bonobos are habitat encroachment as a result of agricultural expansion, and hunting, particularly during past periods of civil conflict .
- Conservation activities have focused on the maintenance of infrastructure, medical services, and education.
- Long-term studies on wild bonobos began at Wamba, Luo Scientific Reserve, in 1973.

Ape status
The study of bonobos at Wamba (in the northern sector of the current Luo Scientific Reserve) started in 1973. The number of bonobos were steadily increasing until some cases of illegal hunting occurred in the 1980's. In order to protect bonobos in this area, a Congolese research center and Japanese researchers established a station for scientific research in 1992, which included both northern and southern sectors on both banks of the Luo River. During two periods of civil war, from 1996 to 2003, bonobos in the northern sector decreased to 40% and those in the southern sector disappeared from half of the area. Bonobos in the northern sector steadily increased from 2003 when research activities resumed, and almost recovered to the previous population size, but the current trend in the southern sector is unknown (Furuichi pers. comm. 2020).

| Pan paniscus | 1996 | 231 | 0.48 | Luo Scientific Reserve (481 km²) | Full count | Hashimoto & Furuichi, 2001 | Density was estimated by number of individuals/ranging area for two study groups. |
Threats
Bonobos in the northern sector decreased to 40% between 1991 and 2002 probably due to hunting by soldiers and local people, but they steadily recovered after 2003 when research resumed. During the war, people who fled from the village made a number of small homesteads in the forest. Currently, local people are expanding their agricultural fields into the protected area (Furuichi pers. comm. 2020).

Conservation activities
In order to strengthen public awareness, an NGO called “Support for Conservation of Bonobos” was established to help in the maintenance of infrastructure, medical services, and education that had been seriously damaged by the war. A joint patrolling program involving people from all homesteads in Wamba village is also implemented (Furuichi pers. comm. 2020).

| Lack of trust and support from local communities | Furuichi pers. comm. 2020 |
Research activities
In the northern sector, behavioral and ecological studies of bonobos have been conducted since 1973, except for a break between 1992 and 2002 due to political instability and civil war. In the southern sector, an ecological survey was being conducted until 1992; currently no research activities are being carried out in this sector (Furuichi pers. comm. 2020).
