Turtle populations continue to face unpredictable challenges from climate change, according to a joint study between researchers from Deakin University and the National Oceanic and Atmospheric Administration NOAA , published today in Nature Reviews Biodiversity. Once severely impacted by overhunting and habitat loss , sea turtles have made a significant comeback due to conservation efforts and legal protections.
The comprehensive study reviews the global status of the seven sea turtle species, detailing findings of a worldwide increase in sea turtle populations, including the discovery that more turtles are nesting on beaches that have implemented stronger protective measures. Efforts such as reducing artificial lighting , which previously disoriented hatchlings, and the adoption of turtle-safe fishing practices, have contributed to these positive trends.
In some areas, hunting sea turtles has decreased as awareness and conservation ethics have evolved. Pacific leatherback turtles, for example, continue to decline due to their arduous migrations across the Pacific Ocean. Climate change poses an ongoing threat, but scientists believe that conservation measures have strengthened sea turtles' resilience. They are vulnerable to environmental changes but thrive when given the opportunity.
Younger generations view turtles less as a resource for consumption and more as valuable components of a healthy marine ecosystem. In some regions, former poachers now serve as eco-tour guides, helping tourists witness nesting turtles. Historically, sea turtles were so abundant in the Caribbean that they frequently bumped into ships at night.
Global declines occurred due to market-driven hunting, fishing net entanglement, and the loss of nesting habitats. However, increased legal protections and conservation initiatives have helped monitor and safeguard nesting sites. Scientists analyzed nesting records and other data to assess global sea turtle populations.
