As Hurricane Erin pelted North Carolina’s barrier islands with strong winds and waves this week, it destroyed many nests of threatened sea turtles, burying the eggs deep in sand or washing them out to sea.
On Topsail Island more than half the 43 loggerhead turtle nests were lost in the storm, according to Terry Meyer, conservation director for the Karen Beasley Sea Turtle Rescue and Rehabilitation Center.
“I didn’t anticipate the water table being so high and the eggs being just literally sitting in water when we got to them,” she said. “I don’t think I’ve seen that on such a wide scale.”
Erin never made landfall and caused no widespread damage to infrastructure despite being twice the size of an average hurricane. But the turtles were not so lucky.
Loggerheads, which are known for their large head and strong jaw muscles, are threatened in the U.S. due to fishing bycatch, according to the National Oceanic and Atmospheric Administration. They are the state’s primary sea turtle and nest every two to three years between May and August, with each nest containing about 100 eggs.
Meyer said that in the big picture, the destruction of dozens of nests will not have a significant impact on the species. But for the many volunteers who spend every summer helping to monitor each nest on the 26-mile (42-kilometer) beach, it’s heartbreaking.
“When you’re digging up a nest that’s got 100 dead, fully developed, ready-to-go hatchlings — I’m old and jaded, but that can be pretty tough to handle,” she said.
About 33 miles (53 kilometers) to the northeast, the storm likely wiped out eight of the 10 remaining loggerhead turtle nests on Emerald Isle, said Dale Baquer, program coordinator and president of the Emerald Isle Sea Turtle Patrol.
One survived when the turtles managed to hatch Wednesday night, while another one likely made it safely through the storm because of its higher location on the dunes, according to Baquer. But there is little chance for the others, though it will not be known for sure until about 75 days into the incubation cycle.
“They really suffered a lot of damage. A lot of high tides and a lot of sitting water. But we’re just going to remain optimistic,” she said.
Both organizations tried to get ahead of the storm by picking up signs or extra stakes or fencing that could be washed out or cause other problems for the turtles.
But there is little they can do given North Carolina’s strict laws about keeping the sea turtle hatching process natural.
Baquer said the only time the group can obtain state permission to help a nest is if it knows it has already hatched or possibly if the tide hits the nest and the eggs are washing out.
“It’s stressful and of course it’s not something you ever get used to, but I think we all have a science mindset that this is nature and this is what’s going to happen,” she said.
