Greater sage-grouse populations have declined significantly over the last six decades, according to a new report by the U.S. Geological Survey. The report documents an 80% rangewide decline since 1965 and a nearly 40% decline since 2002.

The report, “Range-Wide Greater Sage-Grouse Hierarchical Monitoring Framework,” offers an approach to evaluate the effectiveness of greater sage-grouse (Centrocercus urophasianus) conservation efforts and analyze factors that contribute to habitat loss and population change. Researchers found that declines were steepest in the western portion of its range.
