Pastures are fully contained within one allotment. Data is currently available for the Burns, Medford, Lakeview, Spokane, Coos Bay, Vale, and Prineville BLM Districts. Unknown 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).

ALLOTNUM ALLOTNUM String 5 0 0 BLM A unique number assigned to each allotment in a district or inventory ALTPAST ALTPAST String 8 0 0 The polygon identifier for the allotment and pastures. It normally consists of the five-character allotment number, an underscore (_), and the two-character pasture number. All preceding blank characters must be populated with zeros. For example, allotment number 302, pasture number 2, would be input as "00302_02". This field may be used as a link to other related databases, including RAS. The ALTPAST concatenated with Administrative state (derived from BLM_ORG_CD) is unique in RAS, but, in GRA, it is possible to have more than one polygon with the same ALTPAST. In this case, RAS acres are the sum of the polygon acres. Also, not all allotments and pastures are included in RAS. There is dependence between this attribute and the GRAZSYS (Grazing Allotment System CD) attribute. Certain codes in GRAZSYS dictate the form that this (ALTPAST) attribute takes. Certain questions must be asked to determine the correct choice for ALTPAST. The most important is the question: is this area within an allotment or not? This may take some research into old files to determine. Many areas assumed outside of allotments are, in fact, still officially included in an allotment. Because pastures are defined by fences, not exact ownership lines, there are many instances where slivers and small parcels of BLM are fenced in with areas outside of allotments. There are also scattered, isolated BLM parcels that are not included in allotments. The various choices for ALTPAST are described below. Areas within Allotments: 1. General Pastures usually contain a large percentage of public land but can have a large percentage of private land if the pasture is part of a grazing system in an AMP. This is the type of pasture present in most allotments and is always listed in RAS. All records in RAS should have corresponding polygons in GRA, but not vice versa. Because RAS is for billing, GRA will have areas not covered by RAS. Valid value: "05231_11" 2. The FFR (Fenced Federal Range) is an allotment that is mostly private but contains some public land fenced within. This area is always listed in RAS. The ALTPAST should have the standard format as for General Pastures. The MGMTCAT is Custodial (C). 3. Mostly Private Pastures that contain a very small percentage of public land, usually slivers of public land where fences do not follow ownership lines, are another type of areas within allotments. These pastures are included within an allotment and should (but may not) be listed in RAS. The GRAZSYS is "99". Valid value: "06010_99" 4. Exclosures are areas designed and constructed with the idea of keeping livestock and sometimes wildlife out of a particular area. If they are large enough, they should have pasture numbers within allotments and be included in RAS. The GRAZSYS is "EX", "RX", "MX", or "XX". Valid value: "05231_11" Areas NOT within Allotments: 1. Not Allocated areas are closed to livestock grazing through a LUP decision or legislation. These lands generally have an allotment and/or pasture number, but often do not. The GRAZSYS has NX. Valid value: "NOALC" or the standard format for General Pastures. 2. Completely private, state, U.S. Fish and Wildlife Service, or other lands which are not part of any allotment controlled by a BLM district and do not fall under BLM grazing management. These areas would not be within any allotment or pasture and would not be in RAS. The GRAZSYS is "00" (zeroes). Valid value: "OUT." 3. Areas of mostly private, state, or other federal jurisdiction, but with slivers of BLM land fenced in. Lands may be grazed but are not in a BLM allotment or under BLM grazing management. Format includes 2-character code ("ST" for state, "FS" for Forest Service, "FW" for Fish and Wildlife Service, "BR" for Bureau of Reclamation) followed by underscore followed by the other jurisdiction’s allotment number. The GRAZSYS is "00". Example values: "FS_A056", "FS_00177". 4. Unallotted areas are BLM lands not officially assigned to a particular livestock permit. These lands are not closed to livestock grazing and could be assigned to a permit in the future. These areas may have an allotment and/or pasture number and may be included in RAS. The GRAZSYS is Unallotted (UA) or Temporary Use (TU). Districts with large, non-BLM areas surrounding scattered BLM parcels may have large polygons labeled "UNALT" if there is no grazing management on these scattered BLM parcels and no identified fences to block off the large non-BLM blocks. Valid value: "UNALT" or the standard format for General Pastures. BLM Examples: 05506_01, 05515_01 PASTNUM PASTNUM String 2 0 0 Pasture Number: The number used to identify a pasture within an allotment. This field is derived fromAltPast. It is the last 2 characters of AltPast unless AltPast contains "NOALLOC","UNALLOT", or "OUT", in which case this attribute is blank. BLM ALLOTNAME Allotment Name String 50 0 0 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 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. BLM This is a lengthy domain used by multiple datasets. For the full list of values go to: https://gis.blm.gov/ORDownload/Domains/dom_BLM_ORG_CODE.xls PASTNAME Pasture Name String 50 0 0 The name of a specific pasture in an allotment. The GIS pasture name should resemble RAS as much as possible. The GIS pasture name may vary slightly from RAS as the GIS pasture name allows mixed case, generally does not allow for special characters, and may improve consistency in abbreviations. BLM Examples: Otis Mtn, Upper Muddy GRAZSYS Grazing System String 2 0 0 00 00 - Out. Area with no BLM land or otherwise not part of the allotment system.

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 GLOBALID GlobalID GlobalID 38 0 0 An alpha-numeric code that serves as the universal and unique identifier for each feature within the feature class or table of a geodatabase.
