Roundwood output for the U.S. South is taken from the U.S. Department of Agriculture Forest Service Timber Product Output system maintained by the Forest Inventory and Analysis Research Work Unit. Reports of roundwood output for the region have been developed for the RPA National Inventory Database for the years 1952, 1962, 1977, 1981, 1996, and 2001 (see, e.g., Smith and others 2001, 2004). Comparable annual pulpwood production data have been compiled for the region (see, e.g., Johnson and Steppleton 2005). We constructed an annual series of softwood saw-log production by interpolating between the RPA reporting years based on the production of softwood lumber within the region.
We constructed price indices by product class for the U.S. South based on prices reported for substate regions by Timber Mart-South. The index is an average weighted by inventory volumes of the respective regions. Prices are adjusted for inflation by the consumer price index for all urban consumers.
