Abstract
The ability of the Prognosis
BC (Version 3.0) growth model to predict tree and stand growth was assessed against a series of remeasured permanent sample plots, including some which had been precommercially thinned. In addition, the model was evaluated for logical consistency across a variety of stand structures using simulation. By the end of the evaluation process, we were pleased with the performance of the model. Some of the less obvious benefits of growth model evaluation and the value of using multiple approaches when evaluating growth models are discussed.
