DescriptionThe 1993 timber assessment market model (TAMM) is a spatial model of the solidwood and timber inventory elements of the U.S. forest products sector. The TAMM model provides annual projections of volumes and prices in the solidwood products and sawtimber stumpage markets and estimates of total timber harvest and inventory by geographic region for periods of up to 50 years. TAMM and its companion models that project pulpwood and fuelwood use were developed to support the quinquennial Resource Planning Act (RPA) timber assessments and assessment updates conducted by the USDA Forest Service. This report summarizes the methods used to develop the various components of TAMM and the estimates of key behavioral parameters used in the TAMM structure, and also illustrates the use of TAMM with a base and several scenario projections.
