Sage grouse populations have plummeted in recent decades—in part because of habitat fragmentation and loss. In 2010, the U.S. Fish and Wildlife Service determined that the birds warranted protection under the Endangered Species Act. In 2015, however, before the protection went into effect, the Department of the Interior and the Department of Agriculture released the Greater Sage Grouse Conservation Plan, which included input from federal agencies, state governments, ranchers, business leaders, and conservation groups. The management plan determined, among other things, that the greater sage grouse should remain off the endangered-species list, a decision that was widely applauded by sportsmen, and it also established a path to further the bird's recovery. The FWS called the plan the "largest land conservation effort in U.S. history."
