Hurricane Irma struck Florida in September 2017, bringing storm surge and lots of rainfall. While sea turtles have overcome hurricanes for millions of years, a storm of Irma's magnitude had the potential to destroy a high percentage of viable nests. Fortunately, the storm occurred late in the nesting season with only about 700 nests remaining on Broward's beaches. About half of these nests were deemed "lost" due to Irma's impacts, and the remaining nests were either reestablished by County surveyors or untouched by the storm waves. Like Hurricane Irma, the King Tide events that impacted the County's beaches late in the nesting season resulted in just a small number of nests lost.
The increase in local nesting is a sign of optimism for the health of the adult turtle populations, but the hatchling (baby) turtles face challenges of their own. Artificial lighting poses one of the biggest threats to hatchlings in Broward; it can cause the hatchlings to disorient and crawl toward land instead of the sea. Reducing artificial lighting can be easily accomplished by following these guidelines:
-Turn off unnecessary lights
-Use red or amber LED bulbs
-Close curtains or move interior light sources away from windows
-Shield lights that are visible from the beach
-Only light what is needed; reduce decorative lighting
Each of the County's coastal municipalities has its own beachfront lighting ordinance, but most generally require property owners to extinguish lights from sundown to sunup during sea turtle nesting season. More information about your local lighting ordinance and a list of certified lighting fixtures can be found by visiting the Florida Fish and Wildlife Conservation Commission's website. Alternatively, you can contact the BSCTCP for assistance with retrofitting or additional information.
