Campo Grande, Brazil – Nations gathered at the fifteenth Conference of the Parties to the Convention on the Conservation of Migratory Species of Wild Animals concluded a pivotal meeting on March 29, 2026, by approving enhanced protections for 40 migratory species and populations.[1][2] Delegates from 132 countries and the European Union addressed the urgent decline of wildlife that crosses borders, emphasizing international cooperation amid rising extinction risks. The decisions marked a significant step forward for global conservation efforts.
Nearly Half of Protected Migrants in Freefall
A recent assessment revealed that 49 percent of species listed under the CMS now show declining populations, up from 44 percent at the previous conference.[1] This trend underscores the crisis facing migratory animals, with 24 percent threatened by extinction. Habitat fragmentation, overexploitation, and climate change have accelerated losses across land, sea, and freshwater realms.
Experts highlighted how these wanderers serve as vital indicators of planetary health. Their journeys link ecosystems worldwide, yet barriers like dams and pollution disrupt essential routes. The Campo Grande summit responded with concrete actions, adding or upgrading listings in CMS Appendices I and II to mandate stricter safeguards and coordinated strategies.[3]
Spotlight on Newly Shielded Icons
Parties approved protections for a diverse array of species spanning continents and oceans. Terrestrial mammals like the cheetah population in Zimbabwe and the striped hyena joined Appendix I, demanding the highest levels of prohibition on capture and trade. The giant otter, a keystone species in South American rivers, also gained dual listings to foster cross-border habitat security.[1][2]
Birds dominated the avian additions, including the elusive snowy owl and gadfly petrels encompassing 15 species and two subspecies. Shorebirds such as the Hudsonian godwit, Hudsonian whimbrel, and lesser yellowlegs received Appendix I status to curb hunting and wetland loss along flyways. Marine life saw breakthroughs with great and scalloped hammerhead sharks, three thresher shark species, and all devil and manta rays elevated for bycatch mitigation and fishery reforms.
- Snowy owl (Bubo scandiacus): Arctic symbol facing habitat shifts.
- Great hammerhead shark (Sphyrna mokarran): Overfished apex predator.
- Giant otter (Pteronura brasiliensis): Amazon ambassador threatened by gold mining.
- Striped hyena (Hyaena hyaena): Scavenger spanning Asia and Africa.
- Hudsonian godwit (Limosa haemastica): Epic migrant logging 11,000-mile flights.
- European eel: Freshwater migrant plagued by dams and pollution.
These listings bring the CMS total beyond 1,200 species, with 16 occurring in Brazil alone.[2]
Confronting Shared Global Pressures
Delegates tackled multifaceted threats head-on. Fisheries bycatch, illegal killing, and deep-sea mining emerged as top concerns for oceanic migrants. Freshwater species like Amazonian catfish and barred sorubim prompted regional action plans to preserve river connectivity vital for food security in basin communities.
CMS Executive Secretary Amy Fraenkel stressed urgency: “We leave with stronger protections and more ambitious plans but the species themselves are not waiting for our next meeting. Implementation has to begin tomorrow.” Brazil’s COP15 President João Paulo Capobianco echoed this, noting, “We protect species that may never remain within our borders. We invest in a natural heritage we do not own, but are all responsible for.”[1]
The conference adopted 39 resolutions, 15 new Concerted Actions, and 10 species action plans. Initiatives targeted vulture conservation in Africa-Eurasia and jaguar connectivity across the Americas. A new global push against illegal wildlife taking promised enforcement boosts worldwide.
Pathways to Lasting Impact
Brazil assumed CMS presidency for the next triennium, hosting tools like the Atlas of the Americas Flyways to map 622 bird species’ routes. Partnerships with CITES and IPBES will amplify efforts, integrating Indigenous knowledge for holistic strategies. Nine conservation champions received recognition for sustained commitments.
Outcomes extended beyond species lists. Resolutions promoted ecological corridors as biodiversity lifelines and resource strategies for developing nations. Wildlife Conservation Society’s Susan Lieberman noted, “When countries come together with a shared purpose and in the spirit of collaboration, they can deliver meaningful conservation at scale.”[3]
These steps signal multilateral resolve, yet experts warn that on-the-ground action remains critical. CMS COP16 in Germany in 2029 will gauge progress toward the treaty’s 50th anniversary.
The Campo Grande accords offer hope in a darkening outlook for migratory life. They remind us that unified global efforts can bridge borders and restore balance.
Key Takeaways
- 40 species added to CMS Appendices, spanning sharks, birds, mammals, and fish.
- 49% of listed migrants declining; urgent implementation needed.
- New actions target bycatch, connectivity, and illegal trade worldwide.
