Archie Carr National Wildlife Refuge, a 248-acre refuge spanning 20.5 miles long, was designated to protect habitat for what is the most significant area for loggerhead sea turtle nesting in the Western Hemisphere, and the most significant area for green turtle nesting in North America. The long stretches of quiet, undisturbed sandy beaches, with little or no artificial light, are essential to the reproductive success and survival of the 15,000 to 20,000 sea turtles nesting annually.
