A Conservation Success Story: Green Turtles

Too often in the environmental space, the stories are of doom and gloom. While our planet and its natural ecosystems including our rivers, lakes, and oceans are under pressure, there are reasons to celebrate. Many of these stories occur because humans cared and decided to take action.

In late 2025, the green turtle, one of the species of sea turtles that nests on Florida’s coast, has been downlisted from “Endangered” to “Least Concern” globally on the International Union for the Conservation of Nature (IUCN) Red List. The IUCN is a global organization working towards conservation of imperiled plants and animals. The movement of the green turtle to “Least Concern” globally is a win for sea turtles and is a story of hope about how human involvement and protection can work for species recovery.

For over a century, green turtles were exploited for their meat, eggs, and shells, while also heavily impacted as bycatch in fishing industries. By the 1970’s, green turtles in the Atlantic were near extinction. In Florida alone in the 1980’s, there were roughly 4,000 green turtle nests annually, which then climbed to 50,000 nests, or more, each year in the state by the 2010’s. This year, Loggerhead Marinelife Center’s research team alone counted 8,363 green turtle nests on the 10 miles of beach that they monitor.

Global Conservation Efforts

Numerous efforts occurred to help protect sea turtles in the United States and around the world. First, federal protections were put into place such as the Endangered Species Act, which was enacted in 1973. These protections banned harvest of sea turtles for their meat and eggs. In many areas, the nesting beaches themselves were protected from development and poaching activities by establishing standardized nesting beach monitoring to protect the nesting turtles and their eggs. This was coupled with increased educational outreach about why each turtle and each nest matter.

Loggerhead Marinelife Center has been at the forefront of these monitoring and educational efforts since 1983. Another critical aspect related to the increased nest numbers that we see across all three nesting species in Florida came through the development and adoption of the Turtle Excluder Device (TED) for commercial fishing. This unique piece of fishing gear used in trawl fisheries allows the shrimp and other small fish to be captured while pushing any accidentally captured turtles to a hatch, which allows the turtle to swim out.

Continuing This Effort

We should certainly celebrate this conservation win but also highlight that not every regional population of green turtles has increased like we have seen in Florida. We need to ensure continued protection for all sea turtles including the loggerhead, leatherback, hawksbill, and Kemp’s ridley, which are still listed as threatened, endangered, or critically endangered. We have seen how quickly humankind can bring species to the brink of extinction, but when we choose to act as we have done with alligators, bald eagles, buffalo, and now green turtles, we can also help protect and restore these amazing animals and help the ecosystems that they live in.

Our Role in Protecting Turtles, From the Nest to the Water

Loggerhead Marinelife Center has a front row seat to one of the busiest nesting beaches in the world for sea turtles. The 9.5 miles of beach that we monitor and study sees nesting activity by three species: leatherbacks, loggerheads, and green turtles. From year to year, nesting counts can widely fluctuate in a natural cycle, but we are fortunate that all three species are stable or increasing in our region. However, this not always the case globally.

For hundreds of years, sea turtles have been hunted for their meat and eggs as food, and their shells have been harvested to create various products, ranging from decorative combs to eyeglass frames. Historically, they have been caught as bycatch, or unintended catch, in fishing industries that use trawling nets and longlines. In 1973, the Endangered Species Act was enacted to prevent extinction and promote recovery of imperiled species. A recent article published in PLOS ONE, titled Marine mammals and sea turtles listed under the U.S. Endangered Species Act are recovering, provided an in-depth evaluation of the success of conservation efforts in the United States.

All sea turtle species that we see in Florida’s waters are protected at the state and federal level, which often have separate conservation status designations that are separate from those in the Pacific Ocean. These protections prevent harvest of sea turtles and their nests and offer protection to nesting beaches. The science community and commercial fishing industry worked together over 60 years ago to invent the turtle excluder device (TED), which dramatically reduced sea turtle bycatch and net damage without reducing the targeted catch of the fishermen.

The impacts of this level of protection for species on the verge of extinction have been incredibly successful. In 1979, Florida had just 62 green turtle tests, and by 2015 that number increased to over 37,000. Last summer Loggerhead Marinelife Center researchers counted 1,729 green turtle nests on just 9.5 miles of monitored beach. Sea turtles are a critical part of the marine ecosystem both as predators and prey while also helping to provide food to beach- and shore-based predators and nutrients to dune plants. Each species of sea turtle has a unique diet. Leatherbacks feed on jellyfish, keeping their populations in check, and hawksbills feed on sponges on the reef, preventing competition with corals. Sea turtle hatchlings are also a food source for many animals including gulls and popular game fish such as dolphinfish and wahoo.

Sea turtles are still vulnerable to entanglement in derelict fishing gear, ingestion of plastic, and boat strikes; therefore, their continued protection is essential. At the Center, we are grateful for the collaboration with Loggerhead Marinas to help support our vital work to ensure days on the water are filled with wildlife, whether you are fishing, diving, or just cruising.

A message from our friends at Loggerhead Marinelife Center

The words “coral reef” have several connotations. To many it invokes memories of snorkeling or diving in the clear blue waters of the Florida Keys, Caribbean or other tropical parts of the world. Others think of days out on the boat fishing and enjoying time with friends and family. Some may think of a Jimmy Buffet ballad backed up by his band the Coral Reefers.

Few, however, think of the valuable roles coral reefs play in our natural world and in our coastal economies. Worldwide, coral reefs are hotbeds for biodiversity that support 25% of all marine species and over $36 billion in tourism. If you enjoy recreational fishing it is important to know that coral reefs provide shelter and food as well as reproductive and nursery areas for many marine species including those that are commercially and recreationally valuable as food fish.  According to the PEW Charitable Trusts nearly 6 million fishers in the world rely on coral reefs for their products which have an estimated annual value of $375 billion globally. The annual value of coral reef-based fisheries in the US is well over $200 million.

Healthy reefs are not just important for protecting our fisheries and tourism, they are critical for protecting our coastal communities. Coral reefs are the first line of defense against powerful storms by reducing wave height an average of 84%. In many tropical coastal communities, mangroves and coral reefs work in tandem to protect shorelines from severe storms and flooding. A recent study found that Florida’s Coral Reef annually provides over $675 million dollars in flood protection benefits to people, property and jobs – increasing to over $1.6 billion during severe storm events.

Unfortunately, coral reefs are facing many local, regional, and global stressors including declining water quality and unusually high ocean temperatures that led to 2023-24 being declared as the 4th global coral bleaching event. In addition, an outbreak of the virulent “stony coral tissue loss disease” continues to affect corals throughout Florida, the Bahamas, and the Caribbean.

Since coral reefs are so valuable, it’s critical to keep them healthy and resilient. Luckily there is still time to save these amazing ecosystems! Loggerhead Marinelife Center and its partner organizations are focused on all areas of reef conservation ranging from education to habitat restoration and disease control. We need your help – the boating community is key to helping us build innovative private and corporate partnerships that will support protection and restoration of these ecologically, culturally, and economically important ecosystems.  

There are several things you can do to help in this fight to protect this resource for generations to come. Some of the most impactful things you can do are:

  • Use reef safe sunscreen. Visit https://oceanservice.noaa.gov/news/sunscreen-corals.html for more information.
  • Choose sustainable seafood by using a program like Seafood Watch.
  • Practice safe boating by anchoring in sandy areas away from reefs and sea grasses – far enough to ensure the anchor chain does not drag over these sensitive habitats.
  • Be chemical aware. Many cleaning chemicals for boats can harm the reefs as can fertilizers used in your yard at home.
  • Recycle monofilament lines to prevent derelict marine debris.
  • Refuse or reduce single-use plastics. Plastics eventually break down into nano plastics and trickle into the food and water we consume.

I learned to snorkel in the Florida Keys at the age of 5. I have had a lifetime of adventure and excitement on or under the water on coral reefs. I have been very fortunate to have dove with large sharks, snorkeled with sea turtles and watched goliath groupers. At Loggerhead Marinelife Center we want to help build awareness for these special places to ultimately protect them. We know we have kindred spirits in the boating community that love the coral reefs just like we do, and we thank you for being partners in their protection.
