Young Forest Habitat Health Studied in Northeast and Midwest

Year: 2015

Young growth is becoming the new old growth! Early succession forests in the U.S. Northeast and Midwest now account for only 8 percent of total forests, becoming rare like old growth is in the West. Forest Service Forest Inventory and Analysis scientists have begun studying many aspects of early-succession forests.
