TWIGS, an individual-tree-based forest growth projection model, was coupled with a gray squirrel habitat suitability model. The combination of timber forecasting models with wildlife habitat models provides a powerful tool for multiple-use decision-making. The linked models allow forest managers to simultaneously forecast and evaluate the effect of alternative management strategies on timber yield, financial return, and quality of gray squirrel habitat. The linked models were used to evaluate two management options for 9 stands comprising a 258-acre tract on the Hoosier National Forest in southern Indiana. Results for this tract indicated that, for most interest rates, the management option that provided the best squirrel habitat had a lower present net value ($/ac). North. J. Appl. For. 3:46-49, June 1986.
