World atlas of great apes and their conservation

United Nations Environment Programme ; World Conservation Monitoring Centre (2005)

This atlas provides a comprehensive overview of what is currently known about all six species of great apes - chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western gorilla. It gives a thorough background on ape behaviour and ecology for each species, including detailed habitat requirements, the apes' ecological role, and the possible consequences of their decline. Despite the dedicated efforts of many individuals and organizations, the great apes all fall into the endangered or critically endangered category of the IUCN Red List. This atlas offers a full description of the threats, current conservation efforts, and additional protection needed for each species across its entire range.
