Techniques to estimate the volume of timber and woody biomass in your forest

Understanding which trees and how many to remove from your forest is critical to a successful thinning project. This workshop will introduce participants to strategies for installing forest inventory plots and collecting the right data to calculate timber volumes. Participants will learn how to distinguish trees that merchantable and options for utilizing non-merchantable woody biomass.

This workshop is the second in a three-part series on woody biomass in the San Juans. All forest owners are encouraged to attend, regardless of past participation. You may also be interested in our June 30th workshop, How to Manufacture Biochar from Woody Biomass.
