Litter Trap 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Biomass of leaf litter in the MCSE Poplar treatment (T5) and the Mid-successional (SF) and Forested (CF, DF) sites. Litter is collected every one-two weeks from litter traps placed on the ground from late summer through leaf fall.
This datatable is part of the Production of Forested Systems of the Main Cropping System Experiment dataset. This dataset contains the data needed to determine aboveground net primary production (ANPP) in the Coniferous (CF) and Deciduous (DF) 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.
