Abstract:

Globally\, green sea turtles have been a key so urce of food\, medicine\, and materials\, and hold intangible cultural imp ortance. In Baja California\, Mexico\, green turtles sustained human commu nities for millennia\, until intensive\, unregulated commercial harvest fr om 1960–1980 drove rapid population collapse. Following a nationwide cap ture ban in 1990\, decades of conservation measures have led to population increases across the Eastern Pacific\, with abundance approaching or exce eding historical baseline levels.

This decline and recovery trajec tory was reconstructed using local ecological knowledge (LEK) and historic al records\, integrated with ecological monitoring data to estimate long-t erm catch-per-unit-effort (CPUE) and establish a pre-exploitation baseline abundance. I discuss the technical challenges of this approach — includ ing reconciling LEK-derived and scientific CPUE estimates — and how thes e methods can be applied to other long-lived\, data-poor species.

As some green turtle populations recover globally\, this trajectory is gen erating a complex set of management questions. Climate change is introduci ng new pressures on recovering populations\, including nesting beach loss and foraging habitat degradation\, while recovering populations are themse lves generating novel ecological challenges\, such as seagrass overgrazing and range expansion into novel habitats. This is coupled with increasing calls for renewed harvest in multiple jurisdictions (e.g.\, Hawai'i\, Nort hwest Mexico\, French Polynesia)\; whether renewed harvest is viable\, and under what conditions\, depends on highly variable socioeconomic\, cultur al\, and governance contexts. Likewise\, some countries have implemented l ocally-grounded approaches to sustainable harvest that may provide models for future management (e.g.\, Japan\, Australia). Drawing on a 2026 worksh op on sustainable use of sea turtles held at the International Sea Turtle Symposium in Kona\, Hawai'i\, I discuss how moving from blanket protection toward context-specific management will require transdisciplinary researc h — spanning ecology\, social science\, and governance — conducted in collaboration with local and Indigenous communities.
