Freshwater mussels surviving in eastern Maine are the focus of a lawsuit against the Trump administration. The Center for Biological Diversity argues that the government has to give Brook Floater mussels protection under the Endangered Species Act."Freshwater mollusks are the most endangered group of organisms in North America, because they have to have high water quality," said Tierra Curry, a senior scientist with the Center for Biological Diversity. Some of the last healthy populations of Brook Floaters are in the Penobscot River basin and river systems in Downeast Maine according to the state department of inland fisheries and wildlife. The mussels range from Atlantic Canada to Georgia, but have been hurt by water pollution, dams and development, according to the center. Brook Floater populations have shrunk to just a few scattered streams.
