COMPREHENSIVE INTERPRETIVE PLAN Dry Tortugas National Park 2003 LONG-RANGE INTERPRETIVE PLAN Dry Tortugas National Park 2003 Prepared by: Department of Interpretive Planning Harpers Ferry Design Center and the Interpretive Staff of Dry Tortugas National Park and Everglades National Park INTRODUCTION About 70 miles west of Key West, Florida, lies a string of seven islands called the Dry Tortugas. These sand and coral reef islands, or keys, along with 100 square miles of shallow waters and shoals that surround them, make up Dry Tortugas National Park. Here, clear views of water and sky extend to the horizon, broken only by an occasional island. Below and above the horizon line are natural and historical treasures that continue to beckon and amaze those visitors who venture here. Warm, clear, shallow, and well-lit waters around these tropical islands provide ideal conditions for coral reefs. Tiny, primitive animals called polyps live in colonies under these waters and form skeletons from cal- cium carbonate which, over centuries, create coral reefs. These reef ecosystems support a wealth of marine life such as sea anemones, sea fans, lobsters, and many other animal and plant species. Throughout these fragile habitats, colorful fishes swim, feed, court, and thrive. Sea turtles−−once so numerous they inspired Spanish explorer Ponce de León to name these islands “Las Tortugas” in 1513−−still live in these waters. Loggerhead and Green sea turtles crawl onto sand beaches here to lay hundreds of eggs.
