Non-Profit Spotlight: Sea Turtle Conservancy

We shine Leaf Litter’s nonprofit spotlight on the oldest sea turtle conservation organization, the Sea Turtle Conservancy [Read more]

Six years ago, when the worst oil spill in U.S. history assaulted the Gulf of Mexico, we watched in horror, as images of crude-coated crabs, dead dolphins, and smothered shorebirds filled news reports. Many of us probably did not realize that a second wave of wildlife victims—unborn sea turtles—lay in eggs beneath the sands of Gulf Coast beaches, completely unaware of the devastation they’d face upon hatching and trying to enter oil-filled waters.

That is just one example of the many ways the STC actively furthers its mission to “ensure the survival of sea turtles within the Caribbean, Atlantic and Pacific oceans.” STC is perhaps most famous for its longstanding research program in Tortuguero, Costa Rica, the nesting site of more endangered green turtles than anywhere in the Western Hemisphere. This research was initiated in the 1950s by the organization’s founder, noted conservation biologist Archie Carr.

“Archie Carr is the acorn from which this great tree of interconnected efforts to study and protect marine turtles around the world has grown,” said David Godfrey, executive director of STC. According to Godfrey, much of what we now know about the basic biology, physiology, and life history of sea turtles came from research conducted at Tortuguero.

Before this research began, no one knew, for example, that green sea turtles migrate such long distances yet return to the beach where they were born to nest, that within each nesting season females may nest five or six times, that the temperature at which nests incubate ultimately determines the sex of the hatchling, or that emerging hatchlings orient to the water with a number of cues, particularly light. There is much about sea turtles that remains a mystery, but STC’s Tortuguero research has unlocked many pieces of this puzzle which have been consequential to conservation, and they continue to do so today.

Tortuguero has also become a breeding ground, so to speak, for subsequent generations of sea turtle researchers. According to Godfrey, “Hundreds of the world’s leading sea turtle scientists got their start as research assistants at Tortuguero.”

In more recent decades, STC’s research, which now focuses on all sea turtle species, has expanded beyond Costa Rica to Panama, Bermuda, Nevis, Cuba, the U.S., and the Pacific coast of El Salvador. They also have collaborated with conservation research partners in the Guianas and Mexico. As the body of STC research grows, so, too, does our understanding of sea turtles and the impacts—both negative and positive—we humans can have on them.

Godfrey cites an example a bit closer to the organization’s home in Florida. “STC has worked to develop a strong relationship with the Florida Shore and Beach Preservation Association, a group made up of Florida’s coastal counties, coastal planners and engineers, and people who are engaged in the business of beach re-nourishment,” he said.

They have worked together on joint legislation such as a coastal hazard notification law, which requires that buyers of waterfront property be informed of things like erosion rates, rules about building sea walls, and the protection of sea turtle nests. “The Sea Turtle Conservancy has helped change the way that organization discusses and incorporates sea turtles into their agenda.”

“In 2015, exactly 25 years later,” said Godfrey, “there were more than 15,000 green turtle nests in the Archie Carr Refuge.

“That exponential growth is not all because of the STC, but we certainly played a role in it,” said Godfrey.

Today, the organization is run by 11 full-time U.S. employees and another dozen permanent staff members in the other countries where it works, and is supported by more than 100 passionate volunteers who operate the STC’s Barrier Island Education Center and help monitor beaches such as Tortuguero.

As a conservation nonprofit in its sixth decade of successful operation, STC can offer valuable insight into the keys to longevity. Godfrey credits three primary things:

Second: STC’s human resources. “The next generation of people that Archie Carr inspired are in charge now,” said Godfrey, “and we’re continuing what he started very passionately”

Third: the sea turtles themselves. Sea turtles spend less than 1% of their life on land, and are not often visible by people other than boaters and divers. But when they are seen, according to Godfrey, they make a powerful impression that changes and motivates people.


“Here is this giant animal, this living dinosaur, crawling out on this beach that kids were building sandcastles on a few hours earlier. It starts digging an egg chamber, and then it drops 100 plus glistening eggs inside. It’s the middle of the night, and you are inches away from the turtle, so you can hear it breathing. You are watching something that has been taking place for millions of years. You are, essentially, back in the Pleistocene. That experience has such a powerful effect on people, and in my three decades of working in sea turtle conservation, this effect is something that never fails to amaze me.”

Six years ago, in the middle of the night, on a dark beach at Kennedy Space Center, the first wave of tiny sea turtle hatchlings emerged from eggs had been relocated and incubated after the Deepwater Horizon spill.

With the Sea Turtle Conservancy pressing strongly toward its seventh decade, it is likely that many more sea turtles will not only have second chances but less need for them.
