The MGM stand growth simulator is implemented using Microsoft Excel in a Windows environment. The user interacts with the model primarily through a series of Excel Workbooks. Before attempting to design a growth simulation, it is a good idea to have some knowledge of the workbooks used in the MGM environment.

The primary mechanism for designing and implementing a growth simulation is a crop plan. This important concept should be understood before attempting to design a growth simulation. A full description of the procedure for designing a crop plan and making a growth projection, with examples, is provided in the section "Projecting Stand Growth". Detailed instructions for these examples guide the beginner through development and execution of a simple growth projection. Additional examples of crop plans are found in the workbooks.

Some options for developing and processing of many stand simulations are provided in the section on "Batch Processing"
