The U.N. grants international protection to 40 new migratory species
At the CMS COP15 summit in Campo Grande, Brazil, 132 nations expanded UN migratory species protections on March 29, 2026, adding 40 animals — including the snowy owl, giant otter, striped hyena, and great hammerhead shark — to the treaty’s legally binding protection lists. The Convention on the Conservation of Migratory Species now covers more than 1,200 unique species. A new UN interim report released at the summit found that 49% of already-protected species populations are declining and 24% face extinction. The decisions set binding conservation obligations for member nations and signal that coordinated international action remains the strongest tool available to slow wildlife loss.
