About A.P.E.S.

The subject

All ape species are classifed as endangered or critically endangered on the IUCN Red List. In a world with rapidly growing human populations and an ever increasing demand for resources, apes and their habitats are being put under enormous pressure and their numbers are declining at an alarmingly high rate. Ape conservation is a complex issue and fnding long lasting solutions to the numerous pressures they face is an enormous challenge. While deforestation, the bush meat trade, developing industry and human population growth are issues that threaten the majority of great ape populations, there are often site specifc threats that may be unique to certain populations, and there is no “one size fits all” solution to deal with these pressures. Therefore detailed information about the threats faced by each population in addition to accurate measures of population status are crucial for both successfully identifying promising conservation opportunities and for evaluating the success of implemented conservation activities. Information sharing between scientists and conservationists has been limited in the past by a lack of resources, and the difficulty in accessing both published and non-published data from great ape studies.

About this page

One of the main goals of the A.P.E.S project is to overcome these limitations and create a comprehensive database of all that is known about great ape distribution throughout their range, in order to better conserve them. A large team of ape conservationists, donors, scientists and experts in this field have compiled the information you find on this website. Interactive maps with information on ape distribution and their environment will help you to learn more about remaining ape populations and to discover locations that may be of particular interest to you. Various analytical tools will allow you to explore the relationships between ape population status, their natural habitat and human activities or to flter for ape populations of certain characteristics that match your interest. All of this is complemented by extensive text resources, and is hoped that the A.P.E.S database will be a useful and easily accessible tool for a wide range of people in a variety of fields. As the situation of apes is changing rapidly, we are also trying our hardest to keep this website up to date. Please contact us if you have further information to display, or alternatively you can directly use the _A.P.E.S wiki_ to enter new information.


The A.P.E.S project was initiated in 2005 as a joint effort between the Great Apes Section (SGA) of the Primate Specialist Group and the Max Planck Institute for Evolutionary Anthropology. In the first two years of the project the focus was on the compilation of ape population data and the development of an access and release policy. In 2007 the A.P.E.S. project was combined with an initiative by the United Nations Environment Programme World Conservation Monitoring Centre (UNEP WCMC, Cambridge, UK), the Arcus Foundation and the Jane Goodall Institute, which has evolved into the current platform. The website and database is hosted by the Max Planck Institute for Evolutionary Anthropology, the dashboard is hosted by UNEP WCMC.


This project is a true collaborative effort to which many organizations, governments and individuals (see partners) have contributed in terms of data, funding, scientifc and technical expertise, consulting and invested time and effort. We would like to thank everyone for making this project possible!
