On the coast of Florida, Justin Perrault monitors some of the most densely nested stretches of sea turtle beach in the world, extending 9.5 miles along the Atlantic coast from Juno Beach to Tequesta Beach. Surveying Florida’s nesting beaches, he found fewer false crawls during a month of their spring closure: 60 percent of arriving loggerheads successfully nested compared to 48 percent after the beaches reopened in mid-May. “I hear from my staff that when they’re out on the beach, they can see the drag marks where a turtle has been dragged into the woods,” says David Godfrey, executive director of the Sea Turtle Conservancy, which runs a research-and-conservation program focused on green sea turtles in Tortuguero, Costa Rica.
