New Research Highlights Decline of Greater Sage-Grouse in the American West, Provides Roadmap to Aid Conservation

RESTON, Va. – Greater sage-grouse populations have declined significantly over the last six decades, with an 80% rangewide decline since 1965 and a nearly 40% decline since 2002, according to a new report by the U.S. Geological Survey. Although the overall trend clearly shows continued population declines over the entire range of the species, rates of change vary regionally.
