This Project Grant award from the U.S. Department of the Interior Fish and Wildlife Service under the Marine Turtle Conservation Fund (CFDA 15.645) provides $285,011.71 to implement a multifaceted project to reduce threats to marine turtle populations in Malaysia and Vietnam. The key objectives are to: 1) increase enforcement capacity and international cooperation to interdict wildlife trafficking of marine turtles through training, legal framework analysis, and data-driven trade route mapping; 2) pilot social and behavior change campaigns targeting consumer demand and fishing communities to shift behaviors driving illegal turtle trade and bycatch. The primary beneficiaries are government wildlife and law enforcement agencies in both countries, which will gain enhanced collaboration and institutional capacity to manage trade in protected turtle species. Fishing communities will also benefit by learning proper bycatch reporting and handling protocols. The project builds on previous U.S. Fish and Wildlife Service-funded efforts in the region and takes a comprehensive approach to addressing marine turtle conservation challenges.
