Membership directory

Search all Member organisations using the IUCN membership directory.

Through their affiliation with IUCN, Member organisations convene and influence diverse stakeholders at the highest level, all in support of nature conservation. They are also part of a democratic process, voting Resolutions, which drive the global conservation agenda. Furthermore, as an official United Nations Observer, IUCN ensures that nature conservation has an influential voice at the highest level of international governance.

IUCN’s expertise and extensive network also provide a solid foundation for a large and diverse portfolio of conservation projects around the world. Combining the latest science with the traditional knowledge of local communities, these projects work to reverse habitat loss, restore ecosystems and improve people’s well-being. They also produce a wealth of data and information which further feeds into IUCN’s analytical capacity.

The value of working together as a Union cannot be understated, or reproduced. IUCN’s history is built on the results of Members putting knowledge, influence and execution to work for a more sustainable future. 



IUCN’s Crossroads blog is an “open letter to IUCN Members”, providing a platform for Members and selected partners to influence the Membership on key conservation and sustainable development topics.
