This project will enhance the Tree and Stand Simulator (TASS) by adding key components to model the effects of stand management activities (e.g., variable retention, initial stand density, thinning, pruning, and tree improvement) on the predicted wood properties and lumber characteristics of lodgepole pine (Pinus contorta Doug. ex Loud. var. latifolia Engelm.). Destructive sampling of lodgepole pines in the central interior will provide data on which to develop 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 relative density, percent earlywood, percent latewood, fibre length, and coarseness. In addition, measurements of the distribution, size and growth rate of branches will provide information 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 Ministry?s decision support system. Results also will be used to recommend appropriate management regimes to enhance stand values.
