May is the beginning of sea turtle nesting season on many of Florida’s sandy beaches. Beachfront property owners and beach visitors can help nesting turtles and hatchlings by turning off or shielding lights that are visible from the beach at night.
“People’s efforts to keep our beaches as dark as possible at night, without affecting human safety, can make a tremendous difference for nesting sea turtles,” said Robbin Trindell, head of the Florida Fish and Wildlife Conservation Commission (FWC) sea turtle management program. “Female sea turtles and their hatchlings can be disturbed or confused by artificial light, whether it comes from a house, a flashlight or a cellphone camera.”
Sea turtle nesting is starting now on beaches from the Gulf coast, including northwest Florida, to the state’s northeast Atlantic coast and from Miami-Dade County south to the Keys. Nesting began earlier in March along Florida’s southeast Atlantic coast from Brevard County south to Broward County.
Florida is a critically important destination for nesting sea turtles. More loggerhead turtles nest here than anywhere else in the continental United States, with nearly 97,000 loggerhead nests counted statewide during the 2017 nesting season. Leatherback and green sea turtles also nest in significant numbers in Florida.
What are the basics of being sea turtle-friendly?
- It’s a sea turtle night, turn off the light – After sundown, turn off any lights not necessary for human safety. Use long wavelength amber LED lamps for lights that must stay lit and shield lights so they are not visible from the beach. Remember to close shades or curtains.
- Sea turtles get lost in the light – On the beach at night, don’t take flash photos or use bright cellphones or flashlights.
- Sea turtles are protected and must be respected – Stay back and give sea turtles space if you see one on the beach at night. Don’t touch a nesting turtle because it may leave the beach without nesting if disturbed. Remember, it is illegal to harm or disturb nesting sea turtles, their nests, eggs or hatchlings.
- Clear the way at the end of the day – Beach furniture, canopies, boats and toys left behind on the sand may become obstacles that block nesting and hatchling turtles. Fill in any holes dug in the sand.
- Help hatchings home by leaving them alone – Do not handle hatchlings crawling toward the water. Any interference or disturbance by people, such as getting too close or taking flash photos, increases the chances the hatchlings will get confused, go in the wrong direction and not reach the ocean quickly. That makes them vulnerable to dehydration, exhaustion and predators. As with all wildlife, watching from a distance is best.
Buildings and other structures along the beach that need lights for human safety can be lit with long wavelength amber LED bulbs in a downward-directed, well-shielded fixture that is not visible from the beach. The FWC tests lights submitted by manufacturers to see if they meet our “Keep it long (wavelength), Keep it low (lumens and mounting height) and Keep it shielded” requirement. Approved fixtures are less likely to impact nesting or hatchling sea turtles. The agency maintains a list of these certified wildlife-friendly fixtures so property owners along Florida’s coastlines can easily find options that work for human and sea turtle safety.
