• We studied the influence of political turmoil on the population of bonobos (Pan paniscus) in Wamba Forest, Democratic Republic of the Congo. Although six groups of bonobos inhabited Wamba Forest in 1995, we confirmed only three groups in 2005. The home ranges of each group shifted markedly after the civil wars. The poaching of bonobos using guns and snares may have been a cause of the decrease in the number of bonobos and of the change in their home ranges, though we could not confirm whether villagers poached bonobos. We compared vegetation before and after the civil wars with Landsat images. Villagers have been logging the primary forest to create fields, and the secondary forest has expanded. Habitat changes also contributed to the decline in the bonobo population around the village. Historically, eating bonobo has been taboo for the people of Wamba, but it is possible that the frequent movement of people between the village and towns will introduce the custom of eating bonobo to Wamba Village. The political turmoil has had a remarkable effect on not only the lives of the people, but also the status of the bonobo population in Democratic Republic of the Congo.
