A tiny worm is causing big problems for spruce trees in northern Michigan.
The state Department of Natural Resources says an infestation of spruce budworms is attacking balsam fir trees, as well as white and black spruce. The inch-long worms consume the trees’ needles from the top down.
DNR forester Ron Murray says it’s been decades since Michigan has seen such a large outbreak.
“The spruce budworm is a cyclical pest that comes around about every 30 to 50 years," says Murray. "We’re looking at this as potentially being the beginning of the next one.”
