The purpose of this paper is to present a forest management system which combines silviculture, cost and revenue accounting of the following activities: First, regeneration encompassing both cutting and planting for red pine, aspen residual removal, oak shelter woodcuts, site conversion to European larch and improved aspen. Second, timber stand improvement and release covering cuttings in northern hardwood to improve volume/value as well as pruning white pine poles. Third, release of red pine plantations from competing vegetation and release of well stocked red and white pine stands from overtopping hardwood such as oak, maple and aspen. Stratified proportional probability sampling is used for regeneration and timber stand improvement activities. Two criteria used for stratification are state forest area and size of stands as reflected by the number of acres treated. Random walk-through sampling is one method used for both red pine and white pine release for overtopping vegetation. Under each management activity, tasks to be undertaken will be specified along with Goal(s) to be achieved. Cost and revenue accounting is necessary to capture all costs and revenues associated with the three management activities identified above. Cost categories include stand establishment, treatment, harvest and sales costs. Similarly, revenues generated by various practices should also be documented using timber sale proposal completion form. This system of management is used to invest proceeds from revenue bonds to finance high yield timber management operations and to repay the bonds from future timber sales revenue. It can be adapted by others with appropriate modification(s).
