Title: Biomass estimators for thinned second-growth ponderosa pine trees.

Author: Cochran, P.H.; Jennings, J.W.; Youngberg, C.T.;

Date: 1984

Publication Series: Research Note (RN)

Description: Usable estimates of the mass of live foliage and limbs of sapling and pole-sized ponderosa pine in managed stands in central Oregon can be obtained with equations using the logarithm of diameter as the only independent variable. These equations produce only slightly higher root mean square deviations than equations that include additional independent variables. A better estimate of live foliage mass is produced when distance from breast height to live crown is added. A better estimate of live limb mass is produced with the addition of height. For other components investigated (bole wood volume, bole wood mass, bark volume and mass, and total aboveground mass) equations that include height, as well as diameter, greatly reduce the root mean square deviations, compared with equations based on diameter alone.

Keywords: biomass, estimates, second-growth stands, ponderosa pine
