The Loggerhead Marine Life Middle in Juno Seashore, FL introduced a report 25,025 sea turtle nests for the yr 2023. The middle counted 216 leatherback turtle (Dermochelys coriacea) nests, 15,672 loggerhead turtle (Caretta caretta) nests, and 9,137 inexperienced turtle (Chelonia mydas) nests for the nesting season, which ended October 31.
The middle displays and counts sea turtle nests from March 1 to October 31 yearly. That features a practically 10 mile stretch of seashore comprising, Juno, Jupiter-Carline Park and Tequesta. It seems that 2023 was yr for sea turtle nestings as report numbers have been reported up and down the South Florida coast. It’s a nice signal that there are millions of turtles nesting, nonetheless, the big numbers of nests gained’t essentially translate to massive numbers of hatchlings.

“What we’re discovering is that nests that have been laid in June, July and August, when Florida will get highly regarded, the turtle are hatching at diminished charges, so regardless of having a extremely report breaking nesting season right here in Florida, our hatchling manufacturing charges are going to be fairly low,” Dr. Justin Perrault, vice chairman of analysis on the Loggerhead Marinelife Middle advised WPBF 25 Information.
The recent temperatures can have unfavourable results on the hatch charges, and in some instances, can skew the gender ratios of those turtles. For instance, the 2018 examine, “Environmental Warming and Feminization of One of many Largest Sea Turtle Populations within the World” revealed in 2018 documented the intercourse ratios of inexperienced sea turtle hatchlings on Australia’s Raine Island and located that the hatchlings there for the final 20 years (since 2018) have been nearly solely feminine. The island is dwelling to one of many largest sea turtle nesting seashores on this planet, and through the nesting season, greater than 200,000 turtles come to deposit their eggs. Females outnumbered male turtles by 116 to 1.
But the numbers out of South Florida’s Juno, Jupiter-Carline Park and Tequesta seashores are nonetheless encouraging. “This yr’s record-breaking numbers are a victory for sea turtle conservation,” Dr. Justin Perrault, vice chairman of analysis at LMC, mentioned.
