The spruce beetle infestation on the San Juan National Forest (SJNF) has grown to a total of more than 120,000 acres, as detected by the 2015 Aerial Detection Survey Summary for the U.S. Forest Service Rocky Mountain Region.
In the Rocky Mountains, spruce beetles primarily target Engelmann spruce, which grow in high-elevation forests. To address this and other forest-health issues, the SJNF is working several proposals that will include public involvement and environmental analyses this year.
