Human activities such as dredging and careless boating are threatening South Floridaâs mangroves and seagrass. Despite the valuable role that mangroves and seagrass play in the Florida Keys ecosystem, these plants are facing one particularly large threat: Us. In the Florida Keys, human development is the greatest threat to mangrove communities. Since the 1950s, more than 60 percent of mangroves in Monroe County have been destroyed for development. Activities such as dredging, using herbicides, and increasing waste water runoff have destroyed thousands of acres of mangrove habitat.
Three species of mangroves are found in Florida: the red mangrove, black mangrove, and white mangrove. Typically, red mangroves grow along the water's edge, black mangroves grow on slightly higher elevations than the red mangrove, and white mangroves grow upland from the red and black.hite mangroves are normally found upland of the red and black mangroves. The white mangroves are a bit harder to identify than red or black mangroves, since they don't have any obvious features like prop roots or pneumatophores.
