What are the advantages of working with IUCN SOS?
When IUCN Save Our Species awards a grant to an organisation, it is the beginning of a special relationship. We provide support to our grantees throughout the entirety of our shared journey, while adding value along the way by sharing the projects’ impacts and the lessons learned.

Who do we collaborate with?
IUCN Save Our Species works with Civil Society Organisations and government agencies, and offers three types of grants:
- Threatened Species Grants are awarded under each of our initiatives through periodic Calls for Proposals. These are awarded to projects that have a programmatic approach to addressing existing conservation threats.
- Rapid Action Grants are awarded through an open-ended Call for Proposals available to projects responding to emergency situations. They are awarded to shorter project (maximum 12 months) and are designed to enable immediate responses to new and emerging threats.
- Research Support Grants are awarded to young and early scientists in their research to improve the knowledge on threatened species and their ecosystems. Note: Research Support Grants are currently only available under the Fondation Segré Conservation Action Fund.
