Predicting wood stiffness of lodgepole pine trees using acoustic tools and green density

Upstream identification of wood properties using non-destructive testing methods such as acoustic velocity (AV) measurements is important for optimizing allocation to mills or products. We evaluated the effectiveness field AV measurement tools in predicting lodgepole pine stiffness (modulus elasticity, MOE) measured by Silviscan on samples. was trees and logs from six sites Alberta British Columbia. effect MOE estimation calculating averages adjustment factor k green density (GD) at different spatial scales individual tree population. The forest inventory variables prediction were also examined. Prediction tree-level AV, GD resulted R 2 values 0.59. Using estimates averaged plot, site population significantly diminished predictions level. Predicting plot stand level corresponding gave >0.8. Including increased 0.62. can give operationally useful
