A new IUCN report and public online atlas identifies 816 Important Shark and Ray Areas (ISRAs) where protections could help recover declining shark and ray populations.
The Ocean Travellers report, published in December and announced in January, covers nine of 13 ocean regions to date and maps sites that support reproduction, feeding, aggregation or migration for 327 species, including 42 species already protected under the Convention on the Conservation of Migratory Species (CMS). The ISRAs occupy less than 3% of ocean surface in the regions assessed, suggesting targeted area-based measures could be achievable.
Examples include three ISRAs for the critically endangered green sawfish in the Red Sea off Sudan, 27 small ISRAs across the Maldives and a large ISRA south of Hawaiāi the size of Colombia designated for bigeye thresher sharks.
The project began in 2021, with the remaining four regionsā data due later in 2026.
Authors say the atlas is intended to inform national and multilateral policy ahead of the CMS meeting in Brazil in March and to dovetail with other important-area mapping such as CBD ecologically significant areas.
