Loggerhead sea turtles return to the beaches of the South
Atlantic coast each year in late spring to begin nesting. The annual Lights Out
campaign runs from May 1 – October 31 in order to encompass all of nesting
season which can extend into August, and the roughly 60 days it takes for eggs
to hatch. Each barrier island has a team of volunteers ready to walk the beach
each morning in search of turtle tracks and to document when and where a sea
turtle makes her nest. The first loggerhead nest in South Carolina this year
came on May 8, right in the Lowcountry on Dafuskie Island near Hilton Head.
It’s worth
noting that the first S.C. loggerhead nest of 2018 is confirmed in the South
Lowcountry, because most years the first nest is in the northern range along
Cape Romaine National Wildlife Refuge. The second loggerhead sea turtle nest
came the next day on May 9 on Kiawah Island. Cooler than normal water
temperatures due to the prolonged spring may have delayed nesting season for a
few days, but now that the weather has become more tropical it is time for
increased nesting behavior.
Witnessing a large 300-pound
loggerhead sea turtle at night on the beach is an experience that triggers an
emotional response for some. Their ancient cycle of life continues to succeed
using only a ribbon of beach for nesting, and then spending the remainder of
their life in the open ocean. As technology evolves, scientists are using DNA
extracted from eggshells to track generations of female loggerheads that return
to specific beaches over time. When the sea turtle hatchlings emerge from the
nest, they are ingrained on that particular beach, giving them a place they can
call home if and when they return to nest as a mature sea turtle in the future.
