Abstract:
This dataset contains weights of vegetation biomass collected in fertilizer plots from 1989 through 1992. The data were originally collected to analyze the effects of fertilization on vegetation productivity on the Sevilleta NWR.

Geographic Goverage:
Geographic Description: The UNM Field Station and USF&WS Headquarters are the primary support facilities for all research conducted on the Sevilleta NWR. As such the area has also been important as a research site - especially as regards meteorology and monitoring of rodent populations for Hantavirus. While the breaks above and behind are characterized as black grama dominated desert grassland, the immediate area around the Field Station is best described as an ecotonal mixture of Plains-Mesa Sand Scrub and Great Basin Scrub vegetaion greatly influenced by honey mesquite (Prosopis glandulosa) and the drainages which bisect the area at regular intervals and support many one-seed Junipers (Juniperus monosperma). Dominant grasses include 4 species of dropseed (Sporobolis contractus, S. cryptandrus, S. flexuosus & S. airoides) and indian rice grass (Oryzopsis hymenoides)

Description:
Collection sites: Samples were collected at two sites on the Sevilleta NWR. East side lots were located just north of Five-points on McKenzie Flats. West side plots were located on the flats to the north and west of the Sevilleta Field Station. Access was via the AT&T gate and then south along old US 85. Processing: The samples were processed at the UNM Biology annex. Processing included sorting into live and dead fractions, weighing of all samples, ashing for organic content, and some limited analysis for N and P.
