Residual Woody Biomass Inventory Techniques: A Comparative Analysis of Prism Sweep and Line Intersect Sampling Methods

By: Nathaniel Osborne, Dennis Hazel, Mark Megalos, Robert Bardon

Prism sweep and line intercept methods were compared for accuracy and efficiency to measure woody biomass residues on a recently harvested site in Eastern North Carolina. A 100% tally control on 0.1 acre plots was used to compare volume estimates of tested methods. Estimates of residual volume were accurate and not significantly different. Prism sweeps required an average of three minutes per plot, whereas line intersect samples averaged seventeen minutes per plot. Prism sweeps were accurate and five times more efficient than line intersect samples.
