British Virgin Islands: Anegada Professional Review and Guide
"Anegada is the second largest of the British Virgin Islands and lies directly north of Virgin Gorda. It contains 15 square miles and may be reached by air from Tortola. Unlike most Caribbean islands, which are of volcanic origin, Anegada is a coral atoll, and its highest point is less than 30 feet above sea level. Being at such a low elevation it receives little rainfall, so only dry land vegetation, such as loblolly and tamarind, grows well here. There are no mongooses on this flat island; the rock iguana is found only here and on Guana Island, but nowhere else in the world.
The ground is so level and the vegetation so open that you could walk just about anywhere. Since the population is less than 200, you should be able to wander around without worrying about elbow room. Western Anegada has the Flamingo Pond Bird Sanctuary, a salt pond and mangrove area that is home to waterfowl, a variety of herons, terns, osprey, and snowy plovers. Also in this area, the National Parks Trust has imported a flock of flamingos from Bermuda in hopes of re-establishing this bird, once found in great numbers throughout the BVI."
