An information service for great ape conservation and research.

The A.P.E.S. Database and A.P.E.S. Wiki

The IUCN SSC A.P.E.S. Database stands as a comprehensive repository for great ape population survey data, prioritizing a pivotal role in global conservation efforts. Specifically, its objectives include centralizing ape population data, assessing habitat and conservation impacts, aiding decision-making, fostering collaboration, and promoting education on great ape conservation.

The A.P.E.S. Wiki is a collaborative initiative by the IUCN SSC Primate Specialist Group (PSG) Section on Great Apes (SGA) and Section on Small Apes (SSA) to provide centralized and standardized information on ape population status, threats, and conservation and research activities. The Wiki aims to make it easier for researchers, conservationists, and the general public to access and understand information about ape populations worldwide.



Introducing a New Project: Strengthening the Conservation Evidence Base for Great Apes

We are pleased to announce the commencement of a significant project, generously funded by the US Fish & Wildlife Service. Over the next five years, our focus is on improving the survival outlook of great apes. Leveraging data from the IUCN SSC A.P.E.S. Database and Wiki, the project aims to develop insightful products derived from large-scale and global analyses. These products will serve to effectively communicate evidence-based conservation approaches to government decision-makers, conservation practitioners, donors, and private sector stakeholders.
