The salvagers of Key West blessed it - wrecking made their city the richest in Florida. The Florida Reef, stretching 360 miles from Fowey Rocks east of Miami to the Marquesas Keys west of Key West, is the only living coral barrier reef in the continental United States. It is also among the most imperiled. More than 6,000 individual reefs form a great arc concentric with the Florida Keys, sheltering nearly 1,400 species of marine plants and animals, over 500 species of fish, more than 45 species of stony corals, and 35 species of octocorals. The reef system is between 5,000 and 7,000 years old, built grain by grain since sea levels rose after the last ice age. Scientists with NOAA estimate that only about two percent of the original coral cover remains. What took millennia to construct, a few decades of warming water, pollution, and disease have nearly undone.
