Chimpanzees are Close to Extinction in Southwest Nigeria

Abstract

A survey to assess the distribution and status of chimpanzees in the southwest region of Nigeria was conducted in order to identify areas where effective conservation action could be taken. Seventeen sites in five states were surveyed. Information was gathered through directed searches, using hunters as guides, and through interviews with local hunters, community members and government personnel. Findings suggest that chimpanzees survive at only about half the survey sites, and that the viability of these remaining populations is in doubt. According to interviewees, chimpanzees were present at all the survey sites 10 to 15 years ago. These findings suggest that in southwest Nigeria as a whole, their population size and distribution has sharply declined over the last decade. Recommendations include the formal and effective protection of some of these sites.
