BLM Natl Sheep and Goat Authorized Grazing Allotments

<div style='text-align:Left;'><div><div><p style='margin:0 0 11 0;'><span>This feature class was derived from the GIS polygon dataset BLM Grazing Allotments which was downloaded from the Geospatial Gateway in April 2025. Fields were added to the feature classes and calculated as needed to allow the Rangeland Administration System (RAS) tabular data to be joined to the GIS datasets. </span></p><p style='margin:0 0 11 0;'><span>RAS tabular data for Authorized allotments and pastures (as of April 2025) was provided by BLM Rangeland Management Specialist Josh Robbins in April 2025 and processed as dbfs, with fields added and calculated as needed to match the BLM GIS Grazing Allotments feature class. RAS tables and BLM GIS data for allotments were joined using the State Allotment Number, a concatenation of allotment number and BLM Administrative State for allotments (ST_ALLOT_NUM). </span></p><p style='margin:0 0 11 0;'><span>RAS records for Authorized Allotments that did not match during a join operation were tracked in a separate excel sheet from the matching records. Matching records were then joined back to the BLM GIS Allotments grazing feature class and Allotment name fields were edited as necessary. A Status field was added to indicate if the data are either Billed or Authorized and a Source field was added to indicate that the data came from Allotments or Trailing Allotments. An additional field, TR_ALLOT_NUM, was added to designate any Trailing Allotments in the data. Trailing allotments were identified and processed separately for Nevada, since these allotments overlap portions of other allotments. </span></p><p style='margin:0 0 11 0;'><span>Any overlaps in the data were removed via dissolve and Spatial Join.</span></p><p style='margin:0 0 11 0;'><span style='font-weight:bold;'><span>Input BLM GIS Grazing data:</span></span></p><p style='margin:0 0 11 0;'><span>BLM Grazing Pastures and BLM Grazing Allotments are areas of land designated and managed for grazing of livestock. It may include private, state, and public lands under the jurisdiction of the Bureau of Land Management and/or other federal agencies. An allotment is derived from its pastures, where the grazing of livestock is occurring. The attributes of the BLM Grazing Allotment features may be duplicated in RAS, but are considered to be minimum information for unique identification and cartographic purposes.</span></p><p style='margin:0 0 11 0;'><span style='font-weight:bold;'><span>Input RAS Data:</span></span></p><p style='margin:0 0 11 0;'><span>The Rangeland Administration System (RAS) provides grazing administrative support and management reports for the BLM and the public. The Rangeland Administration system serves as an electronic calendar for issuance of applications and grazing authorizations, including Permits, Leases, and Exchange-of-Use Agreements. The Authorized data is current as of April 2025 and was provided by BLM Rangeland Management Specialist Josh Robbins in April 2025.</span></p></div></div></div>
