Photo by Tammy Dorcas Later that day, I remember slowly driving a small jon boat up what I later learned was Fiddler Creek, when I turned a corner in the creek and stopped. There they were—at least 40 turtles in the water, heads popping up periodically to breathe and have a look around. I had never imagined there could be so many turtles in such a small saltmarsh creek. When I first got out of the boat, I quickly sunk into mud up to my waist! More experienced folks explained what to do (I follow instructions well), and we began dragging long seines through the creeks to capture the terrapins. When we finally pulled the first haul up onto a mud bank, it was pandemonium! We had over 45 terrapins in one seine haul! It was very exciting and hectic trying to make sure turtles did not escape back into the water—while simultaneously trying to release carefully the stingray we had accidentally captured—but we eventually got them all into plastic bins and properly labeled so that we could take them back to the house and process them. Processing involves giving each terrapin an individual code, recording any injuries, and taking measurements of the animals before they can be released at their exact spot of capture within a day or so. This study, the most well-known study of this species anywhere in the world, started in 1983 when Whit and his children used a small seine to capture 23 terrapins in the creek across the Kiawah River from the Inlet Cove dock. Biologists do not usually plan long-term, decades-long studies. We begin with a single short-term study, maybe one week or a month, and then just decide to do it again and then don’t stop “doing it again” each year. Whit kept it going, year after year, and I was fortunate enough to start working on the project 12 years after its start in 1995. Over the next few years, I became more involved in the project, and in 2002, as a professor at Davidson College, management of the project was transitioned to me. The Kiawah Island terrapin study continues as the longest study of terrapins in the world and sampling conducted in May 2016 constitutes the 34th year of the study. The benefits of such studies are extraordinarily important when studying long-lived animals like turtles, and we know more about terrapin ecology and conservation as a result the Kiawah study than any other terrapin study in the world. Terrapins are unique animals. They are the only turtle found exclusively in coastal marshes (in southern Florida they live in mangrove forests). Terrapins range from Cape Cod, MA to Corpus Christi, TX and the females get considerably larger than the males. The females typically lay 5–10 eggs in exposed, sandy areas. For the first four years of their life, terrapin babies are almost never seen. They remain in hiding in the marsh, never taking a risk on open water where any number of predators can eat them. Once they reach four or five years old, they start venturing into the many tidal creeks associated with the Kiawah River where they eventually reach sexual maturity and can begin to reproduce themselves.
