The Stand Prognosis Model is a computer program that projects the development of forest stands in the Northern Rocky Mountains. Thinning options allow for simulation of a variety of management strategies. Input consists of a stand inventory, including sample tree records, and a set of option selection instructions. Output includes data normally found in stand, stock, and yield tables and details on selected sample trees. Preparation of input, interpretation of output, and model formulation are described. Guidelines are given for potential uses and limitations.

Keywords: growth and yield, forest management, planning, growth projection, stand models, tree increment, tree mortality
