A History in Pictures from USDA


 
After the beetle outbreak, the same area looked like this. Few of the spruce trees are alive. Originally, most of the damage was done in the Grand Mesa and White River National Forests. But later the beetles spread to the Gunnison, Routt, Uncompahgre, and Arapaho. Plans for controlling the outbreak consisted of working on the borders of the badly infested area so that the beetles could not spread to adjoining uninfested forestlands. Currently this same pest is threatening forests in Montana and Idaho.
