Record Numbers of Endangered Green Sea Turtles Return to Florida to Nest

All seven species of sea turtles are at risk of extinction. But there is hope for one sub-population in Florida.

In 2015, researchers counted 14,152 turtle nests in the Archie Carr National Wildlife Refuge, the principal green sea turtle nesting habitat in North America. This number broke the previous record of just under 13,000 in 2013 and completely shattered past yearly totals, ranging from slightly below 200 in 2001 to slightly over 6,000 in 2011.

Executive director of the Sea Turtle Conservancy David Godfrey says:

“From any spot on the beach during the peak of nesting, we might just within eyesight see see maybe 10 turtles. And imagine, all these turtles are approaching 300 pounds each…That’s a phenomenon we have not seen before in Florida.”

Green sea turtles lay between 75 and 200 eggs per nest, so this past season may have produced as many as 3 million babies. However, because of all the threats they face, such as hungry gulls and fishing nets, only a fraction of these nestlings will likely survive to maturity.

Fortunately, this should still be enough for future viable nesting seasons. In fact, the 2015 turnout was so significant that the United States Fish and Wildlife Service (USFWS) is preparing to downgrade the turtle’s conservation status on the federal list from “endangered” to “threatened.”

The Archie Carr refuge was established in 1990 and since then, the green sea turtle nesting numbers have steadily risen. Lending to this increase are the efforts of conservationists, government officials and residents to reduce pollution and other human effects.

Godfrey says:

“We’re really seeing the fruits of all that work now with the exponential growth in green turtle nesting. That is what it takes with sea turtles in particular, because they grow so slowly. Those hatchlings from 30 years ago are reaching adulthood and coming back.”
