A model for the simulation of growth on mature, uneven-aged northern hardwood stands composed principally of sugar maple (Acer saccharum) was evaluated with independent data. The model provides estimates of basal area, volume, and number of trees by size classes for ingrowth, survivor growth, and mortality. The test data were obtained from cutting-cycle and residual-density studies. Comparisons indicate that basal area and volume are more accurately predicted than is number of trees. Generally, however, the results demonstrate the utility of the model in forest management.
