Reporting regions were based upon combinations of one or more adjacent or nearby Level III or Level IV EPA Eco-Regions with the aim of obtaining a minimum sample size of 45 samples per combined region, where regions posess similar natural vegetation and climatic characteristics. Federal land areas, where data were not collected, are excluded. Purpose: Rangeland reporting regions were designed with the following purposes in mind: 1) represent cohesive areas defined by similar natural climatic and vegetation resource characteristics, 2) be based upon established boundaries familiar to other U.S. agencies and to the general public (EPA eco-regions), and 3) be of size to contain a sufficient number of 2003-2006 NRI on-site rangeland sample values for calculating estimates that can be reported reliably for the class value range they fall within. The regions appear on maps in the article "National Ecosystem Assessments Supported by Scientific and Local Knowledge" http://hdl.handle.net/10113/45178 published in Frontiers in Ecology and the Environment, October 1, 2010, and http://frontiersinecology.org, published online 27 Jul 2010. Federal land areas, where data were not collected, are not shown. Method for Defining Rangeland Reporting Regions Based Upon Ecoregion Boundaries: Level III and Level IV Ecoregion boundaries were obtained from the U.S. Environment Protection Agency website: http://www.epa.gov/wed/pages/ecoregions/level_iii_iv.htm#Level%20III Level IV Ecoregion boundaries were not available everywhere (excluded Arizona and California) at the time of defining the Rangeland Reporting Region boundaries used in the publication. Rangeland Reporting Regions were defined in the following manner: Wherever available, base Level IV ecoregions were used whenever a point total for a single ecoregion exceeded 50 points. Wherever available, Level IV ecoregions were combined with other Level IV ecoregions within the same Level III ecoregion whenever a point total for a single ecoregion was less than 50 points. The criteria for choosing which ecoregions to combine were based upon a careful analysis of the description for each ecogregion (where descriptions were available), taking into account those with similar resource characteristics as well as adjacency and/or proximity of the ecoregions to each other and their point counts. If necessary to obtain the 50 point minimum point count, Level III boundaries were crossed to combine Level IV regions. Where Level IV ecoregions were not available (Arizona and California), Level III ecoregions were used individually or if necessary combined with other adjacent Level III ecoregions to achieve a higher total point count and joined to adjacent Level IV ecoregions in the surrounding states that had them (Oregon, Nevada, Utah, New Mexico). Some lines were digitized at the state borders in order to match between Level III and Level IV boundaries. In two instances the 50-point minimum was not met even by the combined Level III regions (reporting region ec9_1 with 47 points and reporting region mbr14_1 with 45 points). Data were not mapped for the region referred to as "Other" in California.

Use_Constraints: Reported values are averages for all non-federal land in each polygon. Field and/or air photo interpretation data were collected at a statistical sample of points in each polygon. Standard NRCS methods were applied to calculate the indicators. We strongly advise reading all metadata prior to using these data, and carefully comparing indicator definitions before comparing with other data sources.

The value range classes vary between the attributes but typically divide percentages from 0 to 100 into 5 or 6 classes, (e.g. Over 75, 50 - 75, 25 - 50, 25 or less, None). Estimated percent acres represent an average for an area based upon results from the 2003 - 2006 National Resources Inventory (NRI) on-site rangeland sample, a scientifically-based longitudinal-panel survey. Interpretation of NRI results requires an understanding of both the inventory procedures and the amount of uncertainty associated with each estimate. The precision of NRI estimates depends upon the number of samples within the region of interest, the distribution of the resource characteristics across the region, the sampling procedure and the statistical estimation techniques. For more information about the NRI, visit http://www.nrcs.usda.gov/technical/NRI/. Completeness_Report: Level IV ecoregions are not complete for California and Arizona, as of May, 2010. For these states, the polygons are for Level III or lower. The field 'US_L4CODE" contains placeholder information derived from "US_L3CODE". 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.

Glenn E. Griffith, James M. Omernik (Lead Author);Mark McGinley (Topic Editor) "Ecoregions of the United States-Level IV (EPA)". http://www.epa.gov/wed/pages/ecoregions/level_iii_iv.htm Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 52 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 104 regions whereas the conterminous United States has 84 (U.S. Environmental Protection Agency, 2005). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).
