Abstract

Begun in spring 2004, this long-term study at the Sevilleta LTER examines how fertilization affects above-ground biomass production (ANPP) in a mixed desert-grassland. 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 (SEV155, "Nitrogen Fertilization Experiment (NFert): Net Primary Production Quadrat Data") and regressions correlating species biomass and volume constructed using seasonal harvest weights from SEV157, "Net Primary Productivity (NPP) Weight Data." This site was burned by a prescribed fire in 2003.

Spatial coverage

The Black Butte Mixed Grass site is located just inside the gate and to the south of Black Butte. This site is grassland, characterized by Oryzopsis hymenoides, Sporobolus giganteus, Sporobolus flexuosus, Bouteloua eriopoda, and occasional shrubs, including Gutierrezia sarothrae and Yucca glauca. Forbs include Senecio douglasii, Baileyi multiradiata, and Sphaeralcea spp. This site contains the fertilizer study plots, which are located less than one mile from the Black Butte gate on the east side of the road to Five Points.The fertilizer plots are located less than one mile from the Black Butte gate on the east side of the road to Five Points.
