Strategic Objective: To demonstrate to the Parties that national action, while robust, is insufficient for species that cross borders. Ecuador will present its domestic measures (reserves and prohibitions) as the "foundation" that needs to be expanded globally through inclusion in Appendix I.

 

Event Description : Despite robust marine sanctuaries and retention bans implemented by Range States, hammerhead shark populations (Sphyrna lewini and S. mokarran) continue to decline critically (>80%). The highly migratory nature of these species creates a lethal "protection gap": sharks safe in national waters are caught as soon as they cross into international corridors.

 

This event, led by governments in the region, will present irrefutable scientific evidence on migratory connectivity that transcends political borders. Through a dynamic format of rapid-fire presentations, panelists will demonstrate why "sustainable use" mechanisms (Appendix II) have proven insufficient for species with such biological vulnerability. The discussion will focus on how inclusion in CMS Appendix I a conservation measure is not only but also the indispensable legal tool to harmonize national efforts, extend the protection of coastal sanctuaries to the high seas, and ensure the survival of these iconic species.

 

The event will also provide a brief overview of additional shark and ray proposals under consideration at COP15, including other wide-ranging pelagic shark species, highlighting shared threats and the need for coordinated conservation across regions. Drawing on existing CMS experiences with species-specific conservation approaches in other regions, the discussion will illustrate how CMS listings can support practical, cooperative action for migratory sharks and rays, underscoring the Convention’s role in advancing international conservation outcomes.
