SPATIAL REGIONAL TIMBER SUPPLY MODEL FOR INDUSTRIAL EXPANSION.

Major components of the assessment model are a geographical forest survey data base and modules for growth projection, calculation of harvest-transport costs for potential producers, and stand allocation. The stand allocation module assumes mill demands are fixed. Mill demand and harvest-transport cost are the key factors driving the allocation process. The usefulness of the model for studying the impacts over time of demand scenarios or industrial expansion on timber costs is illustrated with an example from the Lake States.
