Stand and Tree Integrated Model

The Stand and Tree Integrated Model (STIM) is an empirical model that integrates a stand-level sub-model with an individual-tree, distance-independent sub-model. This integration allows the two sub-models to interact and reconcile with one another. it was designed to produce potential growth and yield tabels for even-aged stands of coastal western hemlock and trembling aspen. The hemlock model has been calibrated for both natural and thinned stands based on data from coastal British Columbia, Washington and Oregon. The aspen model has been calibrated for both natural and thinned stands based on data from across Canada. [source website]
