Abstract
This dataset is part of a long-term study at the Sevilleta LTER, begun in spring 2004, which 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.Above-ground net primary production is the change in plant biomass, represented by stems, flowers, fruit and foliage, over time and incorporates growth as well as loss to death and decomposition. To measure this change the vegetation variables in this dataset, including species composition and the cover and height of individuals, are sampled twice yearly (spring and fall) at permanent 1m x 1m plots. The data from these plots is used to build regressions correlating biomass and volume via weights of select harvested species obtained in SEV157, "Net Primary Productivity (NPP) Weight Data." This biomass data is included in SEV186, "Nitrogen Fertilization Experiment (NFert): Seasonal Biomass and Seasonal and Annual NPP Data."

Spatial coverage
Location: 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.Landform: Basalt formation., Vegetation: Grasses include blue grama (Bouteloua gracilis), black grama (B. eriopoda), galleta grass (Pleuraphis jamesii), dropseed (Sporobolus spp.), Indian ricegrass (Oryzopsis hymenoides), and burro grass (Scleropogon brevifolius). Creosotebush (Larrea tridentata) also occurs frequently. , siteid: 47Location: The fertilizer plots are located less than one mile from the Black Butte gate on the east side of the road to Five Points.Vegetation: Vegetation includes blue grama (Bouteloua gracilis), black grama (B. eriopoda), galleta grass (Pleuraphis jamesii), dropseed (Sporobolus spp.), and burro grass (Scleropogon brevifolius)., History: The site was burned in 2003 during a prescribed fire conducted by the US Fish and Wildlife Service, siteid: 30
