Poplar Stem Diameter and Biomass Measurements — GLBRC Biofuel Cropping System Experiment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Stem diameter and biomass at destructive tree sampling of the BCSE poplar treatment (G8). Stem diameter at 15cm above ground level is measured annually during the winter months; whole trees are destructively sampled on occasion to develop the relationship between stem diameter and woody biomass.

This datatable is part of the GLBRC Aboveground Plant Biomass dataset.

This dataset contains aboveground biomass data for all treatments (G1-G10) of the GLBRC Biofuel Cropping System Experiment (BCSE). Biomass samples are taken at peak biomass for estimation of aboveground net primary production (ANPP) as well as other sampling campaigns such as cover crop harvest or to capture biomass before agronomic activities. Also included are annual stem diameter measurements and occasional destructive harvests for poplar (G8). See the ANPP protocol for description of the sampling and measurement methods used for each of the treatments. Typically, biomass is sampled around each sampling station (S1-S3) in each replicate plot (R1-R5). Belowground plant biomass is available in a different dataset.
