Del Birmingham on 03 Aug 17Research published in the American Journal of Primatology earlier this month finds that the overall Western Chimpanzee population declined by six percent annually between 1990 and 2014, a total decline of 80.2 percent. The main threats to the Western Chimpanzee are almost all man-made. Habitat loss and fragmentation driven by slash-and-burn agriculture, industrial agriculture (including deforestation for oil palm plantations as well as eucalyptus, rubber, and sugar cane developments), and extractive industries like logging, mining, and oil top the list. In response to the finding that the Western Chimpanzee population has dropped so precipitously in less than three decades, the International Union for the Conservation of Nature (IUCN) elevated the subspecies' status to Critically Endangered on its Red List of Threatened Species.
