As a stop-gap measure, trees already infested by the beetle are being harvested to salvage their lumber before rot and decay set in. So at the same time that the collapse of the U.S. housing market has sent lumber demand submarining, supply is booming.
Good time to build a deck, Leonard concludes. Act now why supplies last, this offer may not be repeated--because the lodgepole pine forest may not be there anymore.
