Characterization of Woody Biomass in North Carolina

By: Nathaniel Osborne

To inform the dialogue on sustainability, the NC State University Extension-Forestry established a sampling study to characterize logger utilization and residual woody biomass across the state. Study sites covered all physiographic regions of North Carolina. On study sites prism sweeps for woody biomass (Bebber and Thomas, 2003) were used to quickly estimate wood residues left after harvesting. Estimated woody biomass residues were compared with scale ticket information from loggers, consultants and timber buyers. Logger utilization was developed using these collected data.

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.
