Performance of a Tree Survival Model on National Forests
Abstract:Tree survival from 546 re-measured permanent plots on four Lake States national forests was compared to predicted survival obtained using an individual-tree survival model. A survival summary was developed by 1-in diameter class for each of 15 species. For trees 4.5 in and larger the model provided good estimates of the actual survival. For trees 1.0 to 4.5 in the results were mixed, showing overprediction for three species and underprediction for four. These differences are partially attributed to the small samples. The predicted rate for all trees of a species, i.e., the composite, agreed with the field results demonstrating the applicability of the model to these forests. North. J. Appl. For. 2:114-116, Dec. 1985.
