WestPro is a Microsoft Excel add-in program designed to simulate the growth of uneven-aged Douglas-fir stands in the Pacific Northwest region of the United States. Given the initial stand state, defined as the number of softwood and hardwood trees per acre by diameter class, WestPro predicts the future stand state for each year of a predetermined time horizon. Management regimes are defined by a target stand distribution and a cutting cycle. Performance indicators include diversity of tree size and species, timber yield, and net present value of harvest over the given horizon.
