SGS-LTER Standard Production Data: 1983-2008 Annual Aboveground Net Primary Production on the Central Plains Experimental Range, Nunn, Colorado, USA 1983-2008, ARS Study Number 6
This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is 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 objective of the long-term ANPP study is to monitor long-term net above ground primary production of the shortgrass steppe community by species. There are 6 sites: ridgetop (ridge), midslope (mid), swale, ESA (replicate 1 not 2), Section 25 (SEC 25), and owl-creek (OC). Each site is located in a different landscape position or soil type on the shortgrass steppe and may be grazed or not. Ridgetop, midslope and swale are grazed and are sampled along a catena. Section 25 is grazed and is located in an upload grassland. ESA is an ungrazed upland grassland an is the control from the Ecosystem Stress Area experiment. Owl Creek is ungrazed and is located in the lowland along the owl creek drainage. There are 3 transects with 5 plots in each transect. Plots in the grazed locations are protected by cages. Because this is a monitoring effort, true replicates across the landscape are not available and it is recommended that the transect be used in calculating mean production at each sampling location.

Data Access Policy
Data sets were provided by the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Program, a partnership between Colorado State University, United States Department of Agriculture, Agricultural Research Service, and the U.S. Forest Service Pawnee National Grassland. Significant funding for these data was provided by the National Science Foundation Long Term Ecological Research program (NSF Grant Number DEB-1027319). The SGS-LTER project (1980-2014) was established as one of the first sites in the US LTER Network and has produced a rich legacy of digital materials including reports, proposals, images, and data packages. Data, products and other information produced from the SGS-LTER are curated as a collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). Materials can be accessed from the Institutional Digital Repository of Colorado State University or upon request by emailing ecodata_nrel@colostate.edu. All data are open for dissemination and re-use for any purpose, but you must attribute credit to the owner and cite use appropriately according to the LTER Data Access Policy.

- Description
- Methods for this dataset: Study Area Locations and Design: There are 6 sites: ridgetop (ridge), midslope (mid), swale, ESA (replicate 1 not 2; see 1D ARS #3 ESA map), Section 25 (SEC 25), and owl-creek (OC). Each location has 15 plots. There are 3 transects with 5 plots in each transect. The plots on the ridge, mid-slope and swale of section 24 and those in section 25 are in grazed pastures and are protected by cages. Chose a random direction and distance to move the cages for the LTNPP harvest next year and re-stake the cages. Plots in the ungrazed locations are chosen randomly each year. The 3 transects are marked by rebar. Measure the distance to the random location of the five plots along each transect. Clip just above crown-level, except for shrubs. Clip only current year growth of shrubs that is green and has leaves, and which grows from an older woodier branch (see Mark Lindquist for description). All live plus recent dead material needs to be harvested from the plot. For the ridge in section 24 OLD-STANDING DEAD will also be collected, but not by species. This means that all old-standing-dead is put in one bag for each plot by species. Old-standing dead is not included in samples from other LTNPP sites. It should be sorted out the same way but it is not saved. Old-dead is not included in any samples (the gray colored material). You can brush the basal old-dead material away from the clipped material with your fingers and sort out other taller stems. Plots are clipped by species. It is usually easier to first clip species other than BOGR-BUDA. There are three cactus species on the site. Only current year growth of OPPO is clipped - these are the small pads. The two 'barrel' cactus are not clipped. There are only some times when combining of species may be done, but it is important that the following 'combining-rules' be followed: 1) The only time combining is allowed is when two species are each less than a gram (this is a few leaves, or one very small stem of an individual). 2) Some species are never combined even if there is only a very small quantity - these are BOGR, BUDA, SPCO, and CAHE. 3) When combining, never combine forbs with shrubs, grasses with forbs, etc. Only combine grasses with grasses, forbs with forbs, shrubs with shrubs. Envelopes with combined species should have codes for all species on the envelope. Do not clip on an ant mound or large disturbance. Note all small mammal, ant, and any other disturbances on the bag. Equipment includes: clippers, pre-labelled bags, sharpie, plant identification field guide, 1/4 m2 round metal clipping frame.
