"Montana’s 18,981,723 acres of non-reserved commercial timberland is divided between public and private ownerships. The public owns 12,945,591 acres, and another 6,036,132 are privately owned.
Montana’s 22.5 million-acre forestland base includes 22.4 million acres of timberland. 85% of Montana’s timberland base is held in unreserved classifications, meaning it is available for harvest. About 60% of unreserved timber-some 11.4 million acres-is held in national forests.
"Timberland, non-reserved" is defined as land available for harvest, and capable of growing at least 20 cubic feet of wood per acre per year. Montana west of the Continental Divide contains some of the most productive forestland in the nation. More than 40% has the potential to produce more than 85 cubic feet per acre per year, and more than 60% is capable of growing between 50 and 119 cubic feet per acre per year." http://www.montanaforests.com/forests/
I believe there is a lot of mismanagement but there is still a lot of logging.
