Human engagement and great ape conservation in Africa.

Abstract

Despite large investments of funding into great ape conservation in Africa, wild populations of gorillas (Gorillassp), chimpanzees (Pan troglodytesssp) and bonobos (Pan paniscus) continue to decline. Causes for this decline fall into three broad categories: habitat loss, illegal hunting, and disease. Contributing factors to all of these causes are linked to pressure from the expanding human population competing for forest resources. We have moved beyond the time of debating the pros and cons of including human engagement activities in conservation. If humans are part of the problem, they must also be part of the solution. To move our understanding of which human engagement activities are effective, what methodologies are being used and best practices for setting up a successful framework, we interviewed practitioners representing 53 projects working in great ape habitat in Africa. The interviewees represented almost 900 years of experience with African great ape conservation. We found that all practitioners agreed that for conservation to succeed, projects must engage with humans utilizing resources from great ape habitats. However, evaluation of such work was elusive. Projects that employed at least one person designated as an educator were more likely to have structured programs, regular engagement activities, and to evaluate their work. To date, little information on the success or failure of the activities has been published, thus perpetuating the problem of relying on personal experience rather than evidence when developing new engagement programs. Additionally, linking human engagement activities to biological impact remains a challenge. The results presented in this paper demonstrate the importance placed on human engagement activities to effectively conserve great apes in Africa while at the same time identifies gaps in our understanding on the link between such activities and project success.
