Temporary hunting and gathering camps, and small hamlets with cassava fields were present within the ICBR. Approximately 10 people lived in a hamlet. According to the villagers, people lived in the forest permanently, and some of their children had never been to the villages along the established roads where there were schools and dispensaries. This situation was, in part, the result of the DRC civil war in the 1990s (Nackoney et al. 2014). Although villagers hunted primarily for their own consumption prior to the civil war, during the warfare the trucking and shipping transportation network collapsed, and the villagers were left with no means of selling cash crops such as coffee beans. As a result, the sale of bush meat became the primary way of earning cash. | Temporary hunting and gathering camps, and small hamlets with cassava fields were present within the ICBR.

Summary
- Bonobos (Pan paniscus) are present in Iyondji Community Bonobo Reserve.
- The population size is unknown.
- The bonobo population trend is unknown.
- The site has a total size of 1,100 km².
- Bonobos at the site are mainly threatened by poaching.
- Conservation interventions have focused on anti-poaching activities, including patrols, removal of snares, and inspecting markets.
Site characteristics
Iyondji Community Bonobo Reserve (ICBR), established in 2012, is located in one of the four bonobo strongholds, i.e. the northern block, Maringa-Lopori-Wamba Landscape (Bonobo Conservation Action Plan, 2012-2022, IUCN) and encompasses approximately 1,100 km² of tropical moist forest that harbors bonobos (Pan paniscus). With the Luo Scientific Reserve and Kokolopori Bonobo Reserve, ICBR contributes to a contiguous 5,627 m² bonobo conservation stronghold.

Ape status
We set up a study site of bonobos in 2010 and habituated two bonobo communities by 2016 in the northern part of ICBR. We confirmed at least four groups at the study site. Although there are bonobos in the middle part, they are unknown. The survival of individuals may be at stake in the southern parts (Sakamaki & Kasalevo pers. comm. 2020)

Threats
Temporary hunting and gathering camps, and small hamlets with cassava fields were present within the ICBR. Approximately 10 people lived in a hamlet. According to the villagers, people lived in the forest permanently, and some of their children had never been to the villages along the established roads where there were schools and dispensaries. This situation was, in part, the result of the DRC civil war in the 1990s (Nackoney et al. 2014). Although villagers hunted primarily for their own consumption prior to the civil war, during the warfare the trucking and shipping transportation network collapsed, and the villagers were left with no means of selling cash crops such as coffee beans. As a result, the sale of bush meat became the primary way of earning cash.
