Foresters use management guides as aids to adjust the stocking of forest stands under management. Typically in uneven-aged forests, foresters manage to some target negative exponential distribution model of the stand diameter distribution. However, mathematical optimization methods provide a better approach to the management of uneven-aged stands, allowing the determination of an optimal diameter distribution based on underlying growth models, given some target objective and sustainability constraints. Optimal uneven-aged stocking guide development is an area of research that is critical to the optimal management of uneven-aged forest stands, and can be used in adaptive management.
Past research in this area has extended classic optimization models for uneven-aged stands into the stochastic realm, and incorporated methods for maintaining and maximizing structural diversity. However, none of the guides developed have been useful for large areas, such as the spruce-fir forest in Maine. Further research will provide optimal guides that could maximize standing biomass (carbon), vertical structural diversity, financial objectives, or combinations of these and other variables important to managing these component stands of northern forest types.
