Endangered Green Sea Turtle Lays Latest Nest

September 8, 2021

SCCF sea turtle monitors last observed a new sea turtle nest on Aug. 22, which turned out to be a rare green sea turtle (Chelonia mydas) nest. Green turtle nesting season in Florida runs from June through September. While this nest comes later than usual, green nests were documented at later dates in August in three previous years.

Overall, while Hurricane Ida impacted 106 sea turtle nests, 171 are still incubating on our beaches.

Hurricane Ida washed over 105 nests but only one was completely washed away. Storm season coincides with Florida’s loggerhead (Caretta caretta) nesting season, which runs from mid-April through October. Sea turtles have adapted to storm events by laying multiple nests across a season and distributing the location of those nests along the beach profile, positioning some in the dunes and some closer to the water. This strategy helps increase the probability that some of a female’s nests will survive the storms (as well as predators, extreme heat, and other threats) and incubate successfully. 

As evidence of this strategy’s success: Despite this year’s storm activity, 40,408 hatchlings have emerged on beaches to date. Of those hatchlings, 1,029 have been green hatchlings, as pictured here, from 26 green nests.

The record number of hatchlings was in 2019 at 48,337.
