In a sweeping act of international cooperation, representatives from 132 countries and the European Union concluded the CMS COP15 summit in Campo Grande, Brazil, by approving protections for 40 new migratory species — including some of the planet's most iconic animals.
The snowy owl, made famous by the Harry Potter films, now joins the cheetah, the great hammerhead shark, the striped hyena, and the giant otter on the list of species granted formal international safeguards under the Convention on the Conservation of Migratory Species of Wild Animals (CMS).
What the Agreement Means
Countries that are party to the CMS are legally obligated to protect listed species, conserve and restore their habitats, remove obstacles to migration, and cooperate with neighboring nations whose borders the animals cross.
The new protections extend to land mammals, marine creatures, and migratory birds alike. The Hudsonian godwit — a long-beaked shorebird teetering on the edge of extinction — also made the list, alongside dozens of other at-risk travelers of the world's flyways, oceans, and savannahs.
"From cheetahs and striped hyenas to snowy owls, giant otters and great hammerhead sharks, CMS parties have backed stronger international action as new evidence shows many migratory species are moving closer to extinction," the convention said in a statement.
Why It Matters Now
A report released ahead of the summit painted a sobering picture: 49% of all species catalogued by the CMS are showing declining populations, up from 44% just two years earlier. Nearly one in four is threatened with extinction on a global scale.
"We came to Campo Grande knowing that the populations of half the species protected under this treaty are in decline," said CMS Executive Secretary Amy Fraenkel. "We leave with stronger protections and more ambitious plans, but the species themselves are not waiting for our next meeting."
Blue Corridors and Flyways
Beyond the headline species listings, nations also agreed on practical conservation measures. New "blue corridors" for sea turtles and designated "flyways" for migratory birds will create protected pathways across borders, helping animals safely complete their epic seasonal journeys.
BirdLife International described the flyway agreements as "a major breakthrough for migratory birds," while the World Wildlife Fund called the overall outcome "a vital step for both people and nature."
"Agreements on blue corridors for turtles and flyways for birds will aid species recovery while conserving the ecosystems essential to sustaining local communities," said the WWF's Colmán Ó Críodáin.
The Hard Part Begins
Conservationists are cautiously optimistic but realistic. Signing agreements is one thing; enforcing them across 132 nations with wildly different enforcement capacities is another. Habitat destruction, overfishing, and pollution continue to accelerate declines for many of the species now on paper-protected lists.
Still, the Campo Grande summit represents one of the largest single expansions of migratory species protections in the convention's history — and a clear signal that the international community recognizes the urgency of acting before these animals run out of room to roam.
