Sail-World.com : Key to saving turtles from climate change is nesting site protection
Key to saving turtles from climate change is nesting site protection

International marine scientists have warned that it will be vital to protect key marine turtle nesting grounds and areas that may be suitable for turtle nesting in the future to ensure that the marine reptiles have a better chance of withstanding climate change.

A new study reveals that some turtle populations in the West Indian Ocean, Northeast Indian Ocean, North Pacific Ocean, East Atlantic Ocean and the East Pacific Ocean are among the least likely to recover from the impacts of climate change.

'To give marine turtles a better chance of coping with climate change, we have to protect their nesting sites and to address threats such as bycatch and coastal development,' says Dr Mariana Fuentes from the ARC Centres of Excellence for Coral Reef Studies (CoECRS) and James Cook University.

'We have seen sea turtle populations decline dramatically in recent decades, and it is likely to get worse due to climate change, as they’re particularly vulnerable to it.

'Climate change can affect their nesting beaches through sea level rise, stronger cyclones and storms; high temperatures can cause their eggs to die before they hatch, or produce an unnatural sex ratio and adversely affect their food sources.'

'At present there are three ways we can tackle climate-related threats,' Dr Fuentes says. 'We can reduce global greenhouse emissions, actively manage for direct impacts from climate change by manipulating the nesting thermal environment with shade, for example, and build the turtles’ resilience, that is, their ability to recover from the negative impacts.

'Reducing emissions is perhaps the biggest challenge, but even if we were able to cut greenhouse emissions immediately, it will not stop the already apparent and unavoidable impacts of climate change on turtles.'

'Also, we don’t know the risks of implementing actions, such as relocating, manipulating or managing turtle populations, or how effective these strategies are,' she says. 'So until we understand more about the risks and effects of active strategies, we should focus on increasing the turtles’ resilience.

'This means that we must better understand what factors influence their ability to recover from the negative effects of climate change.'

Together with sea turtle specialists from around the world, the CoECRS researchers identified that nesting ground vulnerability and non-climate threats, including coastal development and fishery bycatch, as the greatest influences on resilience of marine turtles to climate change.

The researchers also pinpointed the world’s 13 turtle regional management units – large scale conservation areas – that are the least resilient to climate change. These are distributed across three major ocean basins and are important breeding grounds for six of the world’s seven species of sea turtle – flatbacks, loggerheads, green turtles, leatherbacks, hawksbills, olive ridleys and Kemp’s ridleys.

'Eleven of the least resilient conservation areas that we identified are the ones most likely to lose their turtle rookeries,' Dr Fuentes says. 'This highlights the particular importance of protecting key regional nesting beaches and to legally protect areas that may be suitable for turtle nesting in the future.

'Turtles have existed for millions of years and were here long before humans. It would be a complete tragedy if they were to become extinct as a result of our actions and our lack of care.'

The study 'Resilience of marine turtle regional management units to climate change' by Fuentes MMPB, Pike DA, Dimattero A and Wallace BP is published in Global Change Biology. See: http://onlinelibrary.wiley.com/doi/10.1111/gcb.12138/abstract
