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."

Spatial coverage

Location: The EDGE Black Grama site is located within Five Points Black Grama, just to the west of Black Grama Core site. Vegetation: The EDGE black grama site is dominated by black grama (Bouteloua eriopoda). Other prevalent grasses include Sporobolus contractus, S. cryptandrus, S. flexuosus, and Muhlenbergia arenicola., Location: The EDGE Blue Grama site is located on far east side of refuge approximately .5 km due west from the foothills of the Los Pinos Mountains. The study is also just northeast of the Blue Grama Core site. Soils: Sandy loam and sandy clay loam, Vegetation: Vegetation is characterized as Plains-Mesa Grassland, dominated by blue and black grama (Bouteloua gracilis and B. eriopoda) and sand muhly (Muhlenbergia arenicola).
