Boca Grande Sea Turtle Association patrol members have had to battle some stormy mornings over the past week during their daily patrol duties, but they were happy to report three nests hatched. There were no new nests reported this week.
Note: It is illegal to remove a sea turtle, so if you see one, call the FWC Wildlife Alert hotline at (888) 404-FWCC (3922).
“Turtle nesting is starting to drop off, and hatching continues to be in full swing,” said Boca Grande Sea Turtle Association Board member Mel Csank. “It’s very busy for the patrol members right now as we recently surpassed the middle of the season.”
There have been 18 documented green sea turtle nests on island so far this nesting season.
“This is exciting news,” Csank said. “Last season we had only two green turtle nests, so we are trending ahead significantly this year. In 2017 we had a total of 18 green nests, but in 2018 we only had two.”
The north beach renourishment project is complete, and the sand in that area was tilled to soften it, making it easier for turtles to nest. There have been 20 nest relocations due to the renourishment project, and all were very successful.
As of Friday, August 2, there were 576 nests documented by patrol volunteers (18 were green nests and the rest loggerhead), and 634 false crawls have been reported. A false crawl occurs when a turtle makes its way onto the beach but doesn’t produce a nest. Patrol members said they expected a high number of false crawls in June due to the beach renourishment project.
The green sea turtle (Chelonia mydas) faces many threats both on land and in the water and is protected under the Endangered Species Act, according to the National Oceanic and Atmospheric Administration. Their distinctive crawl and nest that looks like a bomb crater are far more rare on the island than the loggerhead (Caretta caretta). Typically we have fewer than 10 green turtle nests each season.
Loggerhead turtles were listed under the Endangered Species Act as threatened in 1978.
Association volunteers would like to remind everyone to be cognizant of your surroundings when visiting the beach. Sea turtle nesting season officially began on May 1, and it’s more important than ever to remember to cover up holes and knock down sand castles when visiting the beach. Always dispose of any trash, and remember – no lights at night.
The hatchlings are about the size of a ping-pong ball, and if they survive land predators like bobcats and coyotes, they feed on small organisms living in seagrasses (called sargassum), where they spend their early developmental years.
