dc.descriptionThe Short Grass Steppe site encompasses a large portion of the Colorado Piedmont Section of the western Great Plains. The extent is defined as the boundaries of the Central Plains Experimental Range (CPER). The CPER has a single ownership and landuse (livestock grazing). The PNG is characterized by a mosaic of ownership and land use. Ownership includes federal, state or private and land use consists of livestock grazing or row-crops. There are NGO conservation groups that exert influence over the area, particularly on federal lands.
dc.description.abstractDatasets related to the Shortgrass Steppe Long-Term Ecological Research project and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive collection within the Repository (http://hdl.handle.net/10217/100254). The data tables and associated metadata documents, which are generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. The Open Top Chamber Experiment Carbon Dioxide (CO₂) Elevation Experiment was conducted in collaboration with partners at the USDA, Agricultural Research Service. Six open-top chambers were installed on the shortgrass steppe in north-eastern Colorado, USA from late March until mid-April from 1997 to 2001 to evaluate how this grassland will be affected by rising atmospheric CO₂. Three chambers were maintained at current CO₂ concentration (ambient treatment), three at twice ambient CO₂, or approximately 720 µmol mol-1 (elevated treatment), and three non-chambered plots served as controls. Each growing season, variables related to soil water, plant physiology, biomass production and community dynamics were measured.
