On the morning of May 14th the first sea turtle nest of the 2020 season was discovered on West Beach in Gulf Shores by the West Beach Sea Turtle Volunteers of Share the Beach - Alabama's Sea Turtle Conservation Program.
It takes between 55 and 70 days for a sea turtle nest to hatch once it's been laid. The earliest this nest would hatch would be July 8th and the latest it would hatch would be July 23rd.
It's estimated that about 7,500 sea turtles make it to the gulf each year from the Alabama Gulf Coast.
According to NOAA, " Sea turtles are ancient species, having been around since the time of the dinosaurs — about 110 million years."
"All six sea turtle species found in U.S. waters are protected by the Endangered Species Act. They are the green, hawksbill, Kemp's ridley, leatherback, loggerhead, and olive ridley."

By far, the most common sea turtle found on Alabama Beach are loggerheads. We normally see a couple of Kemp's Ridley and rarely see Green Sea Turtles.
Also according to NOAA, "It takes 20-30 years for a sea turtle to reach sexual maturity. When a female is ready to lay eggs, she returns to the nesting beach where she was born, even if she has not been there for 30 years! Some females nest every year until the age of 80."
"Loggerheads nest from April to September and generally build 3-5 nests per season, totaling 35 pounds of eggs."
From the Alabama Sea Turtles website:
"During the 2019 nesting season, 114 nests were documented on Alabama beaches. One of the 114 total nests was laid by a green turtle on June 22 on Orange Beach, with the remaining 113 nests those of loggerhead sea turtles.

The 2019 nesting season represents a 36.6% increase in recorded annual nests from 2018, and 51.5% fewer nests than the maximum number of nests recorded in Alabama (n=235 in 2016).
An estimated 7,037 eggs were laid on our beaches in 2019, with an average clutch size of 103.6 eggs per nest. Approximately 3,597 hatchlings successfully made it to the water with an overall hatching success of 51% for nests on Alabama beaches. This hatching success rate includes the impacts of both TS Barry and high levels of predation on the westernmost end of Dauphin Island. Average incubation period was 56 days for this season.
Tropical Storm Barry impacted Alabama beaches on 11-14 July. Collectively, 66 nests (57.9%) were negatively impacted by the storm surge and/or the rise in groundwater associated with this storm system.
We are continuing to work towards mitigating/reducing the negative impacts of artificial lighting on sea turtles. However, in 2019, 17 adult female sea turtles and hatchlings from 7 nests were disoriented due to artificial lighting."
