Turning the Tide: Sea Turtle Populations Show Signs of Recovery Worldwide
A new global study published in Endangered Species Research brings encouraging news for sea turtle conservation: more than half of the world’s sea turtle populations are showing signs of recovery. This comprehensive study, the first major update in over a decade, assessed 48 sea turtle populations worldwide, on the basis of threats such as predation, pollution, coastal development and climate change.
Results submitted by 145 experts from 50 different countries suggest that the conservation status of sea turtles appears to be improving, although significant challenges remain. While many populations, such as the green turtles (Chelonia mydas) in the Atlantic, are recovering, others, such as the critically endangered leatherback turtle (Dermochelys coriacea), continue to face significant challenges. Their extensive migratory patterns expose them to higher environmental risks, making conservation efforts more complex.

A key contributor to this study is ARCHELON’s Research Coordinator, Aliki Panagopoulou PhD. She contributed to the study mobilising the extensive fieldwork and data collection effort on nesting of loggerhead turtles made by ARCHELON in Greece and has provided valuable insights into the status of Mediterranean sea turtle populations. Her work highlights the importance of long-term monitoring and the contribution of local conservation efforts to global assessments.
The study highlights the effectiveness of protective legislation, however, accidental entanglement in fishing gear remains a significant threat. New technologies are being developed to mitigate this issue, but widespread adoption by the global fishing community is essential.

ARCHELON has been monitoring the reproductive activity of the loggerhead sea turtle in Greece for 40+ consecutive years. This research serves as evidence of the positive impact of ongoing conservation efforts and the critical role of our dedicated scientists and researchers/ volunteers in safeguarding marine biodiversity.
