Modeling the impact of stand management regimes on the wood characteristics of lodgepole pine

Abstract

This project will model the effects of stand management activities such as variable retention, initial stand density, thinning, pruning and tree improvement on the predicted wood and lumber characteristics of lodgepole pine by adding key components to the Tree and Stand Simulator (TASS). Destructive sampling of trees from the central interior will provide relationships between the distribution of current crown characteristics (foliar biomass or leaf area) and key ring variables that in turn will predict associated wood characteristics such as fiber length and coarseness. In addition, measurements of the distribution, size and growth rate of branches will provide information necessary to generate knot populations for each tree. This information will then be passed to 2-D and 3-D sawmill simulators already linked to the overall decision support system. Recommendations will be made for appropriate management regimes that will enhance stand values.
