GRAND JUNCTION, Colo. (AP) -- The shimmery, autumn gold of aspen leaves in the fall in the Intermountain West is fading because of a continuing die-off among mature trees.
The aspen die-off has generally moved from south to north, with reports first coming from Arizona years ago.
Areas in Colorado's northwest corner and into southern Wyoming, and areas in Canada, have reported a similar decline in aspen populations.
Aspen ecologist Dale Bartos of the Rocky Mountain Research Station in Fort Collins says he's seeing about 50 percent of aspens die off in areas in southern Utah.
