The large clumps of dead, bleached-out sea grass lining beaches from Siesta Key to Naples are perplexing scientists across the country.

Within seagrass communities, a single acre of seagrass can produce over 10 tons of leaves per year. This vast biomass provides food, habitat, and nursery areas for a myriad of adult and juvenile vertebrates and invertebrates. Further, a single acre of seagrass may support as many as 40,00 fish, and 50 million small invertebrates. Because seagrasses support such high biodiversity, and because of their sensitivity to changes in water quality, they have become recognized as important indicator species that reflect the overall health of coastal ecosystems.
Seagrasses perform a variety of functions within ecosystems, and have both economic and ecological value. The high level of productivity, structural complexity, and biodiversity in seagrass beds has led some researchers to describe seagrass communities as the marine equivalent of tropical rainforests.

"It's not the sun bleaching it. It's more the sun killing the tissue,"Fred Short, a sea grass research professor at University of New Hampshire and founder of SeagrassNet, a worldwide sea grass monitoring project.

"Other environmental stressors, such as hot water from a nuclear power plant, a toxic spill or a deluge of fresh water could have had a similar effect"Manatee grass is a part of the diet for sea turtles and manatees.

"If it's something that continues, then we might have something to worry about," said Penny Hall, research administrator for the Florida Wildlife Research Institute's sea grass group.
