BLM Montana Dakotas GRSG ROD ARMPA: Livestock Grazing Allocation Polygons

Polygon data depicting livestock grazing allocations resulting from the Greater Sage-Grouse Approved Resource Management Plan Amendment (ARMPA) in Montana and the Dakotas. The dataset reflects the final decisions recorded in the ARMPA and associated Record of Decision (ROD), maintaining existing designations for areas available or unavailable for grazing. It was last updated on March 7, 2026, by the U.S. Department of the Interior.

Use Cases

• Map livestock grazing permissions based on the ARMPA and ROD decision polygons.
• Analyze spatial overlap between grazing allocations and Greater Sage-Grouse habitat management areas (HMAs).
• Support environmental impact statements (EIS) by visualizing maintained grazing availability designations.

Strengths

• Data reflects the final, approved decisions from the ARMPA and Record of Decision (ROD).
• Available in multiple geospatial formats (KML, GeoJSON, ArcGIS REST API) for interoperability.
• Last updated on 2026-03-07, indicating recent maintenance.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
