U.N. Convention Expands Protections for Endangered Migratory Species

New Species Listed for Protection
At the 15th Conference of the Parties (COP15) to the Convention on the Conservation of Migratory Species of Wild Animals (CMS), held in Campo Grande, Brazil, representatives from 132 countries and the European Union approved the listing of 40 new species for international protection. Among these are the snowy owl (Bubo scandiacus), the striped hyena (Hyaena hyaena), the giant otter (Pteronura brasiliensis), and the great hammerhead shark (Sphyrna mokarran). The decision reflects growing concerns over the declining populations of migratory species, with nearly half of all species cataloged by the CMS showing signs of decline.
Background and Context
The CMS aims to ensure the conservation of migratory species and their habitats. The recent summit highlighted alarming trends, with reports indicating that 49% of migratory populations are in decline and 24% face extinction. Factors contributing to these declines include habitat loss, climate change, overfishing, and pollution. The snowy owl, for instance, has been declared regionally extinct in Sweden due to a lack of food sources, while the striped hyena faces threats from human-wildlife conflict and habitat fragmentation.
Key Species and Their Challenges
Snowy Owl
The snowy owl, a top predator in Arctic regions, is experiencing population declines, particularly at the edges of its range. Experts emphasize the need for awareness regarding threats such as climate change affecting its prey, lemmings. Norway proposed its listing under CMS Appendix II, which encourages international cooperation for species not yet critically endangered.
Striped Hyena
The striped hyena, with an estimated population of 5,000 to 9,999, is facing severe threats from habitat loss and human conflict. Conservationists advocate for its dual listing under CMS Appendices I and II to enforce stricter protections and promote international collaboration. The species plays a crucial ecological role as a scavenger, yet it remains largely overlooked in conservation efforts.
Giant Otter
The giant otter, an apex predator in South American rivers, is also under threat from habitat degradation and pollution. Its listing under CMS Appendices I and II aims to enhance legal protections and ensure the conservation of interconnected river ecosystems.
Official Statements & Responses
Amy Fraenkel, CMS Executive Secretary, stated, “We leave with stronger protections and more ambitious plans, but the species themselves are not waiting for our next meeting.” Susan Lieberman, Vice President for International Policy at the Wildlife Conservation Society, emphasized the importance of international cooperation, noting, “These listings send a clear signal that the global community recognizes the urgent need to act for species that depend on connected landscapes.”
Criticism & Opposition
While the new protections are welcomed, some conservationists argue that existing measures may not be sufficient without immediate and coordinated action. Concerns remain about the effectiveness of enforcement and the need for comprehensive habitat restoration efforts.
What's Next
The decisions made at COP15 are expected to shape future conservation priorities, with an emphasis on collaborative efforts among countries to protect migratory species. The CMS will facilitate improved data collection and legal protections, aiming to address the pressing threats faced by these species.
