The Center for Biological Diversity recently notified the U.S. Fish and Wildlife Service it intends to sue the agency for failing to make a timely decision on whether the Western ridged mussel should be protected under the Endangered Species Act. These important, imperiled mussels are disappearing from streams and rivers across the three West Coast states and Idaho and Nevada.
In California, one of the 17 locations of live mussel observations since 1990 is Last Chance Creek in the East Branch North Fork Feather River watershed, according to a report from the Xerces Society for Invertebrate Conservation.
