In its 1980 RPA Timber Supply Analysis, the USDA Forest Service applied a combination of the Timber Assessment Market Model and the Timber Resource Analysis System (TRAS) to ascertain how intensification of management on private lands would affect future timber prices. This approach suffered from two shortcomings. First, TRAS combined treated and untreated acres into one weighted average, eliminating the capability of assessing response to individual treatments. Second, alternative types of management intensification could not be examined, since TRAS allowed modeling of only one set of management intensities at a time. The approach presented here, the Timber Resource Inventory Model, simulates management intensification by using yield-table projections for up to five treatment and response levels for a large number of species and sites.
