Cruising Methods, Volume Estimation, and Chipping Productivity for Western Juniper Biomass Market Development

In support of efforts to utilize western juniper for biomass markets, a study was undertaken to: 1) assess cruising methods appropriate for western juniper; 2) develop a form classification for western juniper that combines the potential uses of the tree with likely processing effort required; and 3) estimate chipping cost and production of western juniper. An method for estimating allometric variables used in volume calculation was developed and tested. This estimation method was less expensive to implement and provided no poorer results than measured allometric variables when compared to chipped volumes. The form classification developed segregated processing effort and tree form. Estimates of chipping production were found. Volume equations for total aboveground biomass for juniper remain poor predictors of actual volume.
