My research uses publicly available data to assess how well marine protected areas cover shark and ray species ranges. I focus on identifying gaps in protection & prioritizing areas to protect species most at risk of extinction.
Let’s connect on sharks, spatial conservation, and the future of MPAs!✨

We urge the adoption of the Shark & Ray Red List Index to track progress on ocean conservation goals, like the Global Biodiversity Framework Target 5 & SDG 14.4. Accountability is key for preserving marine life!

The current extinction risk trajectory is driving disproportionate (22%) loss of ecological functional diversity of sharks and rays.
