Endangered sea turtles recovering, but leatherback still staring at extinction
Reduction of threats, ranging from hunting to climate change, has led to the recovery of the endangered sea turtle in the majority of areas of the world.A new study published in the journal Endangered Species Research was done by considering the populations of 48 sea turtles around the world, out of which, more than half of the areas studied depicted declining threats as a boon for their of the turtle populations have come back, though some haven't,' said Stuart Pimm, one of the researchers told the Associated Press.

Endangered sea turtles show global recovery in new survey
LOS ANGELES - Endangered sea turtles are making a comeback in many parts of the world, according to a newly published global survey. The study, featured in Endangered Species Research, found that threats to the marine animals—such as hunting, pollution, and coastal development—are declining in more than half of the areas examined. Although the findings offer hope, researchers caution that not all turtle populations are rebounding equally. Leatherback turtles, in particular, remain under severe threat. Where are sea turtles recovering—and where are they not? Dig deeper The survey analyzed 48 distinct sea turtle populations worldwide and found that those in the Atlantic Ocean are generally faring better than their counterparts in the Pacific. Species like the green turtle, while still endangered globally, are showing notable signs of recovery—especially in regions like Mexico and the U.S., where protections have been in place for decades. According to Stanford researcher Michelle María Early Capistrán, who co-authored the study, population rebounds are now visible due to longstanding efforts like beach conservation and fishing regulation. "By ending commercial harvests and allowing them time to rebound, their populations are now doing really well" in coastal waters off many regions of Mexico and the U.S., said co-author Michelle María Early Capistrán, a Stanford University researcher who has conducted fieldwork in both countries. The other side Unlike green turtles, leatherback turtles remain critically endangered in many areas. The survey notes that all seven regions where leatherbacks are found face high environmental risks. Bryan Wallace, a wildlife ecologist and co-author of the study, told the AP that leatherbacks' long migratory routes—spanning more than 3,700 miles in some cases—expose them to a broader array of threats, including fishing gear entanglements and changing ocean conditions. He emphasized that while new fishing technologies can help reduce bycatch, they need to be widely adopted by global fishing communities to make a difference. Timeline The recovery of sea turtles has been shaped by decades of conservation policy, with legal protections and international efforts gradually showing results. 1973: Sea turtles are listed under the U.S. Endangered Species Act 1990: Mexico bans all captures of sea turtles 2025: First major global update on sea turtle populations in over a decade published Researchers say it has taken decades for these protections to yield noticeable population improvements, underscoring the long-term nature of conservation work. What they're saying Duke University ecologist Stuart Pimm, who was not involved in the study, told the AP that the findings represent one of the clearest conservation wins to date. "Many of the turtle populations have come back, though some haven't," he said. "Overall, the sea turtle story is one of the real conservation success stories."

Endangered sea turtle populations show signs of recovery in more than half the world, survey finds
Endangered sea turtles show signs of recovery in a majority of places where they're found worldwide, according to a new global survey released Thursday. 'Many of the turtle populations have come back, though some haven't,' said Duke ecologist Stuart Pimm, who was not involved with the research. 'Overall, the sea turtle story is one of the real conservation success stories." The study looked at 48 populations of sea turtles around the world. Scientists measured the impacts of threats such as hunting, pollution, coastal development and climate change to the marine animals. In more than half of the areas studied, threats are declining overall, the study found. But there are some exceptions. Sea turtle populations in the Atlantic Ocean are more likely to be recovering than those in Pacific waters. And leatherback turtles are not faring as well as other species. Globally, leatherbacks are considered vulnerable to extinction, but many groups are critically endangered, according to the International Union for Conservation of Nature. All seven of the regions where leatherbacks are found face high environmental risks, said study co-author Bryan Wallace, a wildlife ecologist at Ecolibrium in Colorado. Leatherback turtles are famous for making the longest known marine migrations of any animal – with some individuals swimming as many as 3,700 miles (5,955 kilometers) each way. That feat moves them through a wide swath of regions and may expose them to unique risks, he said. Meanwhile, green turtles are still considered endangered globally, but their populations show signs of recovery in many regions of the world, researchers found. 'By ending commercial harvests and allowing them time to rebound, their populations are now doing really well' in coastal waters off many regions of Mexico and the U.S., said co-author Michelle María Early Capistrán, a Stanford University researcher who has conducted fieldwork in both countries. Sea turtles were protected under the U.S. Endangered Species Act of 1973, and Mexico banned all captures of sea turtles in 1990. But it took a few decades for the results of these actions – alongside efforts to protect nesting beaches and reduce accidental bycatch in fishing – to show up in population trends, she said. Around the world, the problem of sea turtles dying after accidentally becoming entangled in fishing gear remains a major threat, said Wallace. New technologies are being developed to spare turtles, but they must be accepted and used regularly by diverse fishing communities to be effective, he added. The survey was published in the journal Endangered Species Research and is the first update in more than a decade. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Science and Educational Media Group and the Robert Wood Johnson Foundation.
