it's better to compute the indexes when needed, so it's easier to make the relevant adjustments. ie. including and excluding species codes.
Non-Crop (Weed) Species Diversity Index — 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Average species diversity as computed by the Shannon-Weaver H index based on the biomass of each species compared to the total biomass per station. This dataset is based on Non Crop Biomass.
This datatable is part of the Primary Production of Herbaceous Systems of the Main Cropping System Experiment dataset.
This dataset contains the biomass data of herbaceous systems of the Main Cropping System Experiment (MCSE), including Treatments 1-4 and 6-8 at the LTER Main Site (since 1990) and the Mid-successional (TSF) site (since 1993). Included are the data collected at or near peak biomass to estimate aboveground net primary production (ANPP). Systems with multiple harvests or with peaks occurring at different times throughout the growing season may have multiple measurements per year. See the ANPP protocol for sampling and measurement methods of these treatments.
