The diamondback terrapin is a species of turtle that lives in the marshes surrounding Jekyll Island. This unique species has long been a part of the natural and cultural history of the region, but is now threatened by human activities in the marsh. Each summer, dozens of female terrapins are hit by vehicles on the Jekyll Island Causeway as they cross the road in search of good nesting habitat. Most of these injured turtles do not survive, and if this high road mortality continues the local terrapin population may decline to a dangerously low size.

The GSTC and its conservation partners utilize many strategies to help protect Jekyll terrapins.




Each summer, many nesting terrapin females end up in the GSTC’s hospital after getting hit by vehicles out on the Jekyll Island Causeway. Check out our Diamondback Terrapin Rehabilitation page to learn more about how these injured turtles are brought back to health.



Educating Jekyll visitors about diamondback terrapins is a crucial part of protecting the species. Take a look at our Diamondback Terrapin Education page to see the many ways in which the GSTC is trying to spread the word about Jekyll terrapins.
