LANSING, MI (AP)-- The Michigan Department of Natural Resources has released an update on the health of the state's forests, including threats posed by insects and diseases.
Michigan's 20 million acres of forest land supports recreation, forest products and other industries while providing crucial wildlife habitat.
The report outlines efforts to control spruce budworm, a pest that periodically defoliates spruce and fir forests. It says infestations probably will increase over the next 10 years. Experts are looking for high-risk areas in state forests.
