State of the World’s Migratory Species: Interim Report (2026)
The first State of the World’s Migratory Species was launched at the 14th meeting of the Conference of the Parties of the Convention on the Conservation of Migratory Species of Wild Animals (CMS COP14), in February 2024. The report revealed that the extinction risk of CMS-listed species is rising, and that the same trend is evident for migratory species as a whole (including those not listed in the CMS Appendices). This concerning trajectory is the result of intensifying pressure from human activities, with many migratory species exposed to a combination of interacting threats occurring in different locations on their migratory routes.
This interim report, produced for CMS COP15 in response to Decision 14.24 d), provides an update on major developments in the conservation status of CMS-listed species since COP14. It includes an analysis of updates to the IUCN Red List of Threatened Species TM and summarizes insights on population trends and distribution changes from recently published scientific literature. It also provides an update on the extent to which important habitats for CMS-listed species have been identified and protected. Finally, it shines a spotlight on several initiatives that are mapping the routes and pathways used by migratory species.
