COLORADO — The U.S. Forest Service is proposing logging southwest of Glenwood Springs, involving about 2,600 acres in what’s known as the Fourmile area along the borders of Pitkin, Mesa and Garfield counties. The White River National Forest’s proposal includes acreage in all three counties. It involves selective thinning and vegetation clearing in two treatment areas and along several roads to improve forest health, reduce wildfire risk and provide timber, the Forest Service said in a news release. “The timber treatments would improve the forest’s ability to withstand and recover from drought and insect outbreaks by creating more diversity in the size and ages of trees. Additionally, work along roads will strengthen predetermined areas where firefighters could more effectively engage wildfires,” the Forest Service said in its release. …“Active forest management is an important tool for maintaining healthy forests,” Acting Aspen-Sopris District Ranger Jennifer Schuller said in the release.
