Meadows of the sea in 'shocking' decline http://apocadocs.com/s.pl?1246633208
Seagrass meadows are disappearing at an accelerating pace, according to a new report, which is the first to look at the problem on a global scale.
Seagrass meadows, along with coral reefs, mangrove forests, and salt-marshes, provide valuable ecosystem services like nutrient cycling. They also protect edible crustaceans, like shrimps and crabs, and juvenile fish such as salmon. In addition, seagrass meadows provide habitats for endangered species like dugongs, manatees, and sea turtles.
While marine ecologists have been measuring localized seagrass loss for decades, they had never before pooled their information to get a global perspective. So a team led by Michelle Waycott of James Cook University in Townsville, Queensland, Australia pooled data from 215 regional studies, from 1879 to 2006.
They found that the total area of known seagrass meadow had decreased by 29 per cent over the 127 years. They also found that the rate of loss had accelerated, from less than 1 per cent per year in the 1940s to 7 per cent per year since the 1990s.... Overall, the rate of loss is comparable to that for tropical rainforests and coral reefs.

Those meadows are probably having problems because we're not mowing them often enough.
