…An ice storm impacted about 3 million acres of forest in 30 counties in northern Michigan early this spring. Hardwoods like maple and oak were shredded while softwoods like pine snapped in half. Foresters, loggers and sawmills in the region worked around the clock to salvage as much of that downed timber as possible. Now there’s a new concern: Much of northern Michigan’s “wood basket” — worth about $2.2 billion — has been emptied. The glut of timber after the storm had to be harvested quickly, flooding the market and leading to a good year for Up North foresters. But now there’s little left to harvest that the storm didn’t destroy, and foresters worry what the next several years will look like until newly planted trees can replace what the storm took away. The sudden shortage could ripple throughout the supply chain, crippling an important sector of northern Michigan’s economy, foresters say.
