Failure so far by the U.S. Fish and Wildlife Service to rule on whether nearly 300 species of plants and animals, including wolverines at Glacier National Park and White-tailed ptarmigan at Mount Rainier National Park, need Endangered Species Act protection has prompted the Center for Biological Diversity to sue over that lack of action.
In what the organization describes as "one of the largest lawsuits ever launched under the Endangered Species Act," it has filed formal notice of its intent to sue the Trump administration for failing to decide whether 274 imperiled animals and plants across the country should be federally protected. Decisions for these species are years overdue, the group contends.
