Abstract: A key component of the conceptual framework for science at the Sevilleta Long Term Ecological Research project is the location of our study site at the intersection of major "biomes". This dataset demonstrates the convergence of major biomes in the Middle Rio Grande Valley right at the location of the Sevilleta National Wildlife Refuge. The biomes outlined are Chihuahuan Desert, Colorado Plateau Shrub-steppe, Conifer Woodland and Great Plains Grassland. Biome Types are adapted from the Level 1 classification of North American Ecoregions produced for the state of New Mexico by the US Environmental Protection Agency and the Commission for Environmental Cooperation Working Group. We dissolved "Northwestern Forested Mountains" and "Temperate Sierras" into "Conifer Woodland", designated "Great Plains" as "Great Plains Grassland", differentiated "North American Deserts" into "Chihuahuan Desert and "Colorado Plateau Shrub-steppe" and finally we dissolved and "Southern Semi-arid Highlands" into "Chihuan Desert as well. We added a small polygon representing the Ladron Peak Conifer Woodland area which is important to SevLTER research but not depicted at the scale of the Level 1 NA Ecoregion classification.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Purpose:
This dataset is provided as a resource for the LTER community. The purpose of the dataset as presented is to aid in placing SevLTER research activity in a regional context.

Data Quality Information:


Logical consistency report:
Although ecoregion polygons and attributes have been checked for accuracy, some errors may remain.
    Polygons along state borders were reviewed and updated, May 2010.

Completeness report:
Ecoregions were digitized at 1:250,000 scale and are intended for large geographic extents (i.e. states, multiple counties, or river basins).  Use for smaller areas, such as individual counties or a 1:24,000 scale map boundary, is not recommended.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Data were collected using methods that have unknown accuracy (EPA National Geospatial Data Policy [NGDP] Accuracy Tier 10). For more information, please see EPA's NGDP at http://epa.gov/geospatial/policies.html)
