Each volunteer is assigned a section of the beach, called a zone, that they patrol by walking every morning. When they see the distinct flipper tracks of a turtle, it is their esteemed task to determine whether the sea turtle has made a successful nesting attempt or a false crawl. A false crawl happens when the turtles come up onto the beach without digging a nest. Once a determination has been made, volunteers then mark the nest and protect it with wood stakes and colored tape.
