Environmental groups and a tribal government are challenging the removal of federal protections from the Yellowstone grizzly bear.
More than a half-dozen environmental groups and one tribal government signed onto three separate letters Friday announcing their intent to sue the U.S. Fish and Wildlife Service over its decision to lift Endangered Species Act protections from the Yellowstone grizzly bear. The Northern Cheyenne Tribe also signed onto one of the letters.
The announcement that a lawsuit is coming was expected. The letters were sent the same day the final delisting rule was published to the federal register.
