The USGS National Wetlands Research Center has documented that Seagrasses in the northern Gulf of Mexico constitute an ecosystem in trouble. From studies in St. Andrews Bay, Period Bay, the Chandeleur Islands, and the Gulf Islands National Seashore, scientists have discovered that declining seagrass acreage ranges from 12% to 66% in bays and estuaries of the Gulf of Mexico. Not only are seagrasses disappearing, but they are also changing in species composition, densities, and patchiness.
