KBS045:Forest Increment Survey

In 1998, a new protocol was instituted for measuring the diameters of every tree greater than 5 cm dbh in the coniferous and deciduous forest plots. Trees are usually measured in January. Exponential equations are used to estimate tree mass for each year. The goal is to estimate wood production for any given time period (usually one year) as the difference between two estimates of mass.


KBS019-006 Litter Trap Biomass from Forested Systems
Leaf litter collected from traps under poplar and forest sites in the Main Cropping System Experiment.
KBS019-015 Forest Woody Biomass via DBH
Woody Biomass estimated from the diameter at breast height in LTER Coniferous Forest (CF) and Deciduous Forest (DF) treatments.
KBS019-017 Forest DBH - Raw Data
The raw DBH (tree diameter at breast height) values from the forested sites, diameters are measured at 4 points along the trunk.
KBS019-020 Top Tree Species in the forested treatments
This datatable is derived from the woody biomass survey by dividing the individual species biomass by the total plot biomass and then taking the average of the proportions over each treatment.
KBS019-022 Forest Aboveground Net Primary Productivity
The annual biomass production in the forested plots estimated from stem diameters and leaf trap data. Species specific allometric equations are used to calculate the woody biomass increment.
kbs019-024 Forest Woody Biomass Annual Production
The table contains the annual woody biomass production from the forest plots. It is computed from the DBH Woody Biomass table by subtracting the standing biomass this year from the standing biomass from the previous year.
