JACKSON, Wyo. (AP) - New research indicates aspen trees are making a comeback on parts of the National Elk Refuge.
The number of aspen trees on the preserve in northwest Wyoming has been in decline for decades.
The refuge is undertaking a study with Montana State University to quantify how many young aspens are positioned to survive and where they're located.
Refuge biologist Eric Cole says there's some evidence of some aspen regeneration, at least on the extreme north end of the refuge.
Cole tells the Jackson Hole News & Guide (http://bit.ly/1q4etuL) that researchers are most interested in the capacity of the stand to regenerate and their rate of height growth.
The refuge is working on a conservation plan that includes maintaining sufficient numbers of aspen trees.
