Mid-successional Understory Biomass — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Aboveground biomass of non-crop species (i.e., species other than main crop and/or cover crop) in LTER MCSE Mid-successional forest treatments (TSF) at or near peak biomass.
This datatable is part of the Primary Production of Forested Systems of the Main Cropping System Experiment dataset.
This dataset contains the data needed to determine the biomass and aboveground net primary production (ANPP) in the Coniferous (TCF) and Deciduous (TDF) Forest sites of the LTER Main Cropping System Experiment (MCSE). Allometric equations are used to estimate the standing woody biomass (since 1998) of each tree, based on the diameter at breast height (DBH; for trees >5 cm in diameter), typically measured in January. Annual woody production is estimated as the difference in the woody biomass of each tree between consecutive years and annual primary production as the sum of annual woody production and leaf production. Leaf production is estimated as the biomass of leaf litter collected in litter traps deployed in late summer through leaf fall. Litter collected from Poplar (T5) and Mid-successional (TSF) plots is also included.
