AUM (Animal Unit Month) - The amount of dry forage required by one animal unit for one month based on a forage allowance of 26 pounds per day. RAS (Rangeland Administration System) - The system used by BLM for billing for grazing on public land. The system contains allotments, pastures, permittees, grazing fees and other pertinent information related to public land grazing. Fenced Federal Range - Generally a small amount of public land fenced with a large amount of private land. Seed Ripe - In terms of plant phenology, it is that point from where seed becomes hard to the beginning of seed dispersal. Custodial - An area where the grazing system is not defined and resource values on public land are protected.

Data is currently available for the Burns, Medford, Lakeview, Spokane, Coos Bay, Vale, and Prineville BLM Districts. Some attribute data is contained within the Rangeland Administration System database. Accuracy of those attributes is assured through the annual billing process. Unknown Manuscripting - District staff copied grazing allotment and pasture boundaries onto mylar quad-based map overlays. Existing fence lines shown on U.S. Geological Survey (USGS) quad maps were copied onto the mylar maps. Additional fence lines were added from orthophoto quads, aerial photos, GPS or other sources. Allotment/pasture name and number attributes were also placed onto the mylar maps in preparation for digitizing. Road and Stream lines already available in digital line graph (DLG) format as part of the USGS cultural features theme or from the Forest Service's cartographic feature file (FS_CFF) theme were copied directly into the GRA theme. Some fence lines defined as following or paralleling a road at a set distance and others defined as left or right stream banks were input by copying the road or stream centerline into a temporary file, building a buffer based on the distance from the centerline, and adding the buffered line to the GRA theme. BLM contractors or GIS staff digitized some of the lines from the map overlays or conducted "heads up" digitizing using Arc/INFO ArcEdit module. Heads up digitizing involved digitizing lines on the screen using scanned aerial photos (i.e. DOQ), satellite imagery, or digital raster graphic (DRG) files as a backdrop. Labels were added, lines and polygons attributed, and the theme run through quality control and corrected, where necessary. The individual quads were merged into a single Arc/INFO coverage, attributes were rechecked, and then the theme was inserted into the District libraries. (NOTE: It is expected that GPS and other data sources will be used in the future to more accurately locate fence lines and collect/import this data into this theme).

The polygons are attributed by an allotment number and naming system that is consistent with the Rangeland Administration System (RAS). All land, regardless of ownership or whether it is used for livestock grazing, may be covered with a polygon. 43CFR4100.05 and BLM Manual H-4110-1.22D Feature Class 0 OBJECTID Internal feature number. BLM 8 character code Required field See definition for format examples, exceptions, and variations. OBJECTID OID 4 0 0 ALLOTNUM A unique number assigned to each allotment in a district or inventory BLM 5 Character code ALLOTNUM String 5 0 0 ALLOTNAME The official name assigned to a specific allotment. The allotment name should resemble RAS as much as possible. The GIS allotment name may vary slightly from RAS as the GIS allotment name allows mixed case, generally does not allow for special characters, and may improve consistency in abbreviations. If the allotment is a Fenced Federal Range (FFR), include FFR in the name (e.g., "Pickled Butte FFR"). See Section 9.5.2 for constraint data rules that apply to this field. BLM Examples: Coal Mine Creek, Moffet Table Allotment Name String 50 0 0 MGMTCAT Range condition assessment categories as defined in the Rangeland Program Summary (RPS). RAS contains an equivalent field and the two should match. BLM Management Category String 1 0 0 I I - Improve current unsatisfactory resource(s) condition. BLM M M - Maintain current satisfactory resource(s) condition. BLM N N - Not Applicable BLM C C - Custodial Allotment: manage "custodially", while protecting existing resource values. BLM GIS_ACRES GIS_ACRES Double 8 0 0 GIS_ACRES is calculated when the submitted polygon is approved for incorporation into the dataset. The standard spatial reference of Geographic (NAD 1983) cannot be used for calculating acres, so the features are projected as determined by the BLM_ORG_CD of the record. These projections all utilize linear units of meters, so the ESRI Geodatabase-controlled field SHAPE.AREA can be used to convert to acres with the factor based on the U.S. Survey Foot: GIS_ACRES = SHAPE.AREA * 0.0002471044. GIS_ACRES is calculated using the NAD 1983 Albers Equal Area project except for the following OR/WA Districts: Prineville: NAD 1983 USFS R6 Albers Coos Bay, Eugene, Lakeview, Medford, Roseburg, Salem: NAD 1983 UTM Zone 10N Burns, Spokane, Vale: NAD 1983 UTM Zone 11N BLM Examples: 2.4, 46.1, 350.5 BLM_ORG_CD BLM Org Code String 5 0 0 A combination of the BLM administrative state and field office which has administrative responsibility for the spatial entity. This includes which office covers the entity for planning purposes and which office is the lead for GIS edits. Another agency or individual may have the physical management responsibility for the on-the-ground entity. This field applies particularly when a spatial entity crosses resource area or district boundaries, and the administrative responsibility is assigned to one or the other rather than splitting the spatial unit. Similarly, OR/WA BLM may have administrative responsibility over some area that is physically located in Nevada, Idaho, and California and vice versa. When appropriate, the office can be identified only to the district or state level rather than to the resource area level. This field is auto calculated on record creation. However, it can be changed to correct the value. This is a lengthy domain used by multiple datasets.
