Preliminary Stats Reveal Record Nests, But Environmental Challenges Loom
Amidst the timeless ritual of sea turtles laboring ashore to lay their eggs, Florida has witnessed a historic year with record-breaking nesting numbers. Preliminary state statistics indicate over 133,840 loggerhead turtle nests, surpassing the previous 2016 record, and more than 76,500 green turtle nests, exceeding the 2017 mark. Similar high nest numbers were reported in South Carolina, Alabama, North Carolina, and Georgia. So, Florida Sea Turtles set new records.
Justin Perrault, VP of Research at Loggerhead Marinelife Center, described this year’s nesting as remarkable, with local records shattered. However, this success story hides an ominous future, as climate change threatens these ancient creatures. Rising sea levels, more powerful storms, and altered migration routes due to climate change pose challenges, compounded by the impact of human activities.
Hurricane Idalia’s surge in August wiped out a significant number of nests along Florida’s Gulf Coast, underscoring the vulnerability of sea turtles to natural disasters. Female turtles, which generally lay eggs in a three-year cycle, face disruptions to nests and the challenge of returning to the sea after nesting. Climate change intensifies these threats, with rising temperatures affecting nest sex ratios and hatchling size.

A recent study led by FSU professor Mariana Fuentes highlights the need for sea turtles to adapt their nesting times to cope with changing environmental conditions. However, Fuentes expresses concern that the rapid pace of today’s climate changes may outpace the turtles’ ability to evolve.
The warmer nests resulting from climate change produce more female turtles, affecting the delicate balance of their populations. Electric lights, coastal development, and predation by animals further complicate the survival journey of hatchlings. While nest numbers soar, experts caution that the actual hatchling production may not be as robust.
Despite the current record-breaking numbers of Florida Sea Turtles set new records conservationists like Perrault warn of a potential decline in the future. “Our hatchling production may not be that great,” he said, emphasizing the importance of sustained conservation efforts to ensure the long-term survival of these ancient mariners in the face of climate change.
