Mixedwood Growth Model (MGM)

The  Mixedwood Growth Model (MGM) is a deterministic, distance-independent, individual tree-based stand growth model for the Boreal forest. It is capable of summarizing both tree and stand characteristics. Summaries are provided as yield tables and charts portraying averages and totals for the conifer and hardwood components. Growth may be simulated for stands provided as a tree list or stand table, including juvenile trees < 1.3m height,  or trees may be simulated based on an assumed tree diameter distribution. 

Pure or mixed stands of white spruce, aspen, lodgepole pine and black spruce may be simulated. Growth relationships have been formulated based on data from Alberta. Regional variants for British Columbia, Saskatchewan, and Manitoba allow use of local species codes, site curves, and tree volume estimation equations.

This site provides information about the approach to modeling stand growth, software availability, and usage (including detailed do-it-yourself examples).
