Marine Protected Areas and Sea Turtle Conservation

As nations strive to meet the 30×30 target of the Kunming-Montreal Global Biodiversity Framework, recent findings show challenges in marine protected areas (MPAs) and their effectiveness in conserving sea turtles. A study published in June 2025 reveals that only 23 per cent of sea turtle hotspots are within MPAs. Additionally, climate change is pushing these turtles into busier shipping zones, increasing their risk of vessel strikes.

About the 30×30 Target

The 30×30 target aims to protect 30 per cent of the world’s oceans by 2030. Currently, only 8 per cent of the ocean is designated as MPAs, with just 3 per cent effectively managed. This target is crucial for biodiversity conservation, particularly for vulnerable species like sea turtles.

Climate Change Impact on Sea Turtles

Climate change is altering the habitats of sea turtles. As ocean temperatures rise, turtles are moving towards cooler waters. This shift takes them outside traditional protected areas and into high-risk zones like the North Sea and Mediterranean. These areas are characterised by heavy shipping traffic, increasing the likelihood of fatal vessel strikes.

Study

Researchers analysed over 27,000 sea turtle sightings and more than 1 billion ship locations. They identified the need for adaptive conservation strategies that can respond to changing ocean conditions. The study assessed three climate scenarios to predict future habitat loss for sea turtles. Under the worst-case scenario, up to 67 per cent of habitats could vanish by mid-century.

Adaptive Conservation Strategies

To address the challenges posed by climate change, researchers recommend several strategies. These include expanding MPA coverage to future turtle hotspots within national Exclusive Economic Zones (EEZs). They also advocate for dynamic, climate-informed MPAs that can adapt based on species distribution changes.

Integrating Shipping Regulations

Coupling MPAs with targeted shipping regulations is essential. Implementing speed reductions in high-risk areas can reduce vessel strike risks. Existing models, such as WhaleWatch, demonstrate the effectiveness of real-time data in guiding vessel operations.

Future Directions

The study puts stress on the necessity for innovative conservation approaches. As species migrate in response to climate stress, conservation strategies must evolve. Integrating high-resolution species models with shipping data can lead to more effective marine conservation efforts.

Conclusion on Marine Conservation

The findings advocate for a shift towards climate-smart, adaptive protections. This approach ensures that conservation efforts follow the species rather than being limited to static locations. The urgency of implementing these strategies is critical for protecting marine biodiversity and achieving global conservation targets.
