A sequence of multivariate techniques (after Golden 1981) including hierarchial classification, detrended correspondence analysis, and multiple discriminant analysis was used to classify forest types in the Great Smoky Mountains National Park. Multiple regressions were used to develop predictive equations for canopy tree productivity (periodic bole volume increment) from environmental variables and measurements of tree growth. An index of topographic shape was constructed to quantify the effects of landform on forest distribution and productivity. The topographic index "protection" was the most important variable for predicting forest productivity. Elevation was the most important variable determining vegetation distribution with protection the second. Predictability of forest productivity from environmental factors was lower on older logged and farmed sites than on undisturbed sites. For. Sci. 35(2):338-348.
