| Abstract: |
| Net primary production is a fundamental ecological variable that quantifies rates
of carbon consumption and fixation. Estimates of NPP are important in understanding
energy flow at a community level as well as spatial and temporal responses to a range
of ecological processes. While measures of both below- and above-ground biomass are
important in estimating total NPP, this study focuses on above-ground net primary
production (ANPP). Above-ground net primary production is the change in plant biomass,
including loss to death and decomposition, over a given period of time. Volumetric
measurements are made using vegetation data from permanent plots collected in SEV297,
"Extreme Drought in Grassland Ecosystems (EDGE) Net Primary Production Quadrat Data"
and regressions correlating biomass and volume constructed using seasonal harvest
weights from SEV157, "Net Primary Productivity (NPP) Weight Data."

| Description: |
| Derivation of Biomass and Net primary Production:Data from SEV297 and SEV157 are used
to calculate the seasonal and annual production (i.e., biomass) of each species in
each quadrat for a given year. Allometric equations derived from harvested samples
of each species for each season are applied to the measured cover, height, and count
of each species in each quadrat. This provides seasonal biomass for winter, spring,
and fall.Seasonal net primary production (NPP) is derived by subtracting the previous
season's biomass from the biomass for the current season. For example, spring NPP
is calculated by subtracting the winter weight from the spring weight for each species
in a given quadrat. Negative differences are considered to be 0. Likewise, fall production
is computed by subtracting spring biomass from fall biomass. Annual biomass is taken
as the sum of spring and fall NPP.
