Plaintiff Western Watersheds Project brings this Complaint to challenge the “precluded” part of the Service’s March 1010 Finding that ESA listing of greater sage-grouse and the distinct population segments is “warranted, but precluded,” as being arbitrary, capricious, and contrary to law. WWP asks the Court to quickly review and reverse that “precluded” determination, and remand with instructions for the Service to promptly publish a proposed listing rule within a set deadline, so that greater sage-grouse can finally receive the ESA protections that science, and the Service’s own “warranted” determination, show are necessary to prevent this icon of the sagebrush sea from declining further toward extinction.
