Lights Out For Sea Turtles

poster from wfit.org

It’s near the end of sea turtle season for Florida’s panhandle. Turtle hatchlings are guided to the sea by moonlight, but tragically, artificial light from buildings and houses divert the hatchlings away from the water to certain death. Thanks to the Pensacola Beach Turtle Ordinance, hatchlings are given a darker and safer passage to the sea.

Nesting and hatching season runs from May 1-October 31. According to seefloridaonline.com, scientists estimate only 1 in 1000-10,000 babies survive to adulthood and it can take 15-50 years before a sea turtle is capable of reproducing. Talk about a long adolescence. Sea turtles often return to the beach where they hatched. There are five species of sea turtles found in the Gulf of Mexico, four species nest in the Pensacola Bay area.

The Turtles Being Protected.

The Green Turtle (Chelonia mydas) named after the color of its body fat, is unique among sea turtles as it is primarily vegetarian.  

The Hawksbill Turtle (Eretmochelys imbricata) is a smaller turtle with a beautiful shell, hunted nearly to extinction. These turtles rarely nest in Pensacola, but they have been spotted in the Florida Keys.

The Leatherback Turtle (Dermochelys coriacea) is the largest of the endangered sea turtles, reaching up to 8 ft. Their favorite food is jellyfish.

The Loggerhead Turtle (Caretta caretta) is the most common sea turtle in Florida. 80% of all the Loggerhead turtles in the U.S. nest in Florida.

Kemp’s Ridley (Lepidochelys kempii) is the rarest and smallest sea turtle. Their favorite food is the blue crab.

                                                  

          

The Pensacola Beach Turtle Ordinance.

The Pensacola Beach Turtle Ordinance, which for the moment is a voluntary ordinance, asks residents to turn off lights on the beach at night, close the blinds, or install sea turtle friendly lights. The ordinance will require compliance of all existing properties by 2018, though many are complying with the ordinance already.

Here is a link to the ordinance:

Why Are Sea Turtles In Danger?

When hatchlings first emerge from their nests in the sand, instinct tells them to follow the brightest light towards the water. That light is supposed to be the moon and stars, but lights from houses, hotels, streetlights and shopping centers outshine the moon and distract the hatchlings. Hatchlings are run over by cars, or quickly eaten by gulls and other prey.

On Pensacola Beach, the Santa Rosa Towers proactively shifted to sea turtle friendly lighting in the beginning of the summer. I hope the beach community continues to follow in suit, making the area safer for sea turtle hatchlings as they make their way to the sea.

How You Can Help.

-It’s always a good idea to turn off any light that isn’t necessary.

-Use red, amber or LED bulbs, which are less disruptive to hatchlings.

-Close blinds or use curtains to dim indoor light.

The Sea Turtle Conservancy (www.conserveturtles.org) suggests we follow these three tips:

1. Keep It Low- Low mounting height and low wattage lights are best. Turn off flood, spot and pole lighting.

2. Keep It Shielded- Direct lighting to the ground and shield fixtures so you cannot see the bulb or lamp.

3. Keep It Long- Sea turtles are less disturbed by long wavelengths of light (570 nanometers or longer)


If you happen to see a sea turtle, please don’t disturb it as they are endangered and federally protected. I’m happy to see that there are also local residents like myself who believe it's important to conserve the beach's ecosystem and protect its inhabitants.

What are your thoughts on light pollution and sea turtle conservation? I would love to hear from you.  "Sea" you later. (I just couldn't help myself.)

Coastlines Get A Fall Cleaning

September 20, 2014 the Ocean Conservancy hosted it’s 28th International Coastal Cleanup day. According to the Ocean Conservancy website, more than 12 million pounds of trash was collected by volunteers all over the globe from their local coastlines and waterways.

That’s Amazing! Seriously, 12 million pounds is a great deal of trash. That is trash that won’t be in the ocean threatening the ecosystem, thanks to the efforts of locals taking time to clean up their environment. What a fantastic way to usher in the fall season. The project was shared on Facebook and Twitter and it looks as though this year’s International Coastal Cleanup was a phenomenal success. PR professionals are vital in projects like these to spread the word and reach out to volunteers.

Ocean Conservancy is a small organization that began in 1972 with the purpose of fighting for a healthy ocean. Since 1986 the International Coastal Cleanup has been one of their hallmark projects, according to the Ocean Conservancy website. The organization works to protect the Atlantic and Pacific Coasts, the Arctic, and my home the Gulf of Mexico.

Marine trash is a significant problem. Only a small percentage of marine trash is from marine sources. According to the California Coastal Commission website, 80% of marine trash is from land-based sources. It poses hazards for ocean life and it impacts coastlines when washed ashore. It threatens wildlife that becomes entangled, and ingestion is deadly. Sea turtles often mistake plastic bags as jellyfish, their favorite food. Marine trash is also a disruption in habitats, littering the ocean floor, reefs and oyster beds.

It is paramount that trash is removed from beaches and waterways to reduce threats to wildlife and the ecosystem. International Coastal Cleanup day is an example of normal people making an impact in the environment. We can’t wait for big corporations to fix everything, sometimes we need to roll up our sleeves and get to work in our own back yard. I look forward to participating in next year's International Coastal Cleanup day. Until then I’ll be taking a trash bag along whenever I go to the beach for a little housekeeping.

Did you participate for International Coastal Cleanup day? I look forward to hearing your thoughts about International Coastal Cleanup and would love to know what things you do to help restore our coastlines.
