Economic perturbations are not new to the U.S. forest sector. The reduction in public timber harvest in the 1980s shifted timber supply and industrial capacity and increased imports. In the 1990s, the U.S. pulp and paper sector went through major restructuring, partly in response to increased recycling, and economic globalization resulted in U.S. furniture production moving largely off-shore. The housing market collapse in the recent recession has severely affected U.S. lumber and panel markets.
