Assessment of Prediction Bias in Crown Biomass Equations for Important Conifer Species of the Inland Northwest
Several crown biomass equations have been developed for local, regional, and national scale biomass estimation across the United States. The prediction equations most commonly used were developed by Brown (1978) and Jenkins et al. (2003). Because of the widespread application of these equations for …

An Investigation of Fraxinus Americana Branch Sway Using a 3 Dimensional Motion Capture System
… were calculated after portions of the tree crown mass were removed. Wind loaded branch sway frequencies ranged between 0.2 and 1.1 Hz while the pull and release test induced mean frequencies of 0.2 Hz. There was no significant difference between phase angle shifts or frequencies after the …

Application of Randomized Branch Sampling to Conifer Trees: Estimating Crown Biomass
… design. RBS utilizes the branching form of the crown itself to draw probability samples and generate unbiased estimates. When implemented correctly, RBS can also greatly reduce the costs in time and labor of sampling when the purpose is estimating attributes borne within crown portions of trees. …
