Denver (AP) A few campgrounds on national forest land in Colorado will open later than usual so trees can be sprayed to ward off bark beetles.
Other campgrounds will stay closed until snow can be removed.
The U.S. Forest Service announced earlier that 21 campgrounds and two recreational sites in Northern Colorado and Southeastern Wyoming will stay closed for the summer because of hazards from trees killed by bark beetles. The trees can fall as the roots start
Trees in some of the campgrounds in the Arapaho and Roosevelt national forests will be sprayed to keep away the beetles.
Bark beetles have killed huge swaths of pine trees in Colorado, Wyoming and South Dakota. The bugs that burrow under the bark have killed about 1.5 million acres of trees in Colorado.
