DescriptionA modified version of the DFSIM Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) growth and yield simulator, DFSIM WITH ECONOMICS, now has an economics option that allows the user to estimate present net worth at the same time a silvicultural regime is simulated. If desired, the economics option will apply a volume adjustment multiplier in yields used in the analysis to reflect application of small-plot research results to average operating conditions or to account for genetics or other local conditions..It can also account for salvage of mortality. Prices can be entered as a table of values or as an equation that can vary with diameter. Logging costs can be entered as a table or can be generated internally for a short-span cable system. Logging costs can vary by diameter and volume harvested. Other harvest-related costs can be included on a per acre basis and also on a unit volume basis. Prices and costs can be trended using an annual percentage rate of change that is applied for a 50-year period.
An interactive program, SIMIN2 WITH ECONOMICS, can be used to prepare the input data in the format required by the DFSIM WITH ECONOMICS program. Both programs are available from the Biometrics Group, Pacific Northwest Forest and Range Experiment Station, Forestry Sciences Laboratory, P.O. Box 3890, Portland, Oregon 97208.
