The story
A 1947 film shows an estimated 40,000 Kemp's ridleys nesting at Rancho Nuevo in one day; by 1985 fewer than 250 females nested all year. Fifty years of binational beach protection and turtle-excluder devices in trawls rebuilt nesting to thousands — recovery that stalled after the Deepwater Horizon spill.
What's killing them
- Shrimp-trawl bycatch
- Oil spills in core habitat
- Cold-stunning events
- Single main nesting beach
