Oil and Gas Allocation Polygons for Greater Sage-Grouse Habitat in Montana and Dakotas

Polygons depict oil and gas allocation decisions from the Greater Sage-Grouse Approved Resource Management Plan Amendment (ARMPA) in Montana and the Dakotas. The data reflect stipulations and allocations within Habitat Management Areas (HMAs) and carry forward decisions from previous RMPs. It is provided by the Department of the Interior's Bureau of Land Management.

Use Cases

• Analyze spatial overlap between ARMPA Oil and Gas allocation polygons and GRSG Core Areas or HMAs (e.g., LMHMA, CHMA, PHMA) for habitat impact assessment.
• Map the application of more stringent stipulations from earlier RMPs within GRSG HMAs to understand regulatory layers.
• Compare allocation decisions inside HMAs, which are changed by the ARMPA, with those outside HMAs, which carry forward from previous RMPs.

Strengths

• Official decision data from the Bureau of Land Management's Approved RMP Amendment and Record of Decision (ROD).
• Polygon data specifically details allocations for the Greater Sage-Grouse (GRSG) resource management plan.
• Data is available in multiple formats including GeoJSON, KML, and ArcGIS REST API for flexible access.

Limitations

• No row or column count is provided, making the dataset's scale and attribute structure unknown.
• The description is highly technical, requiring domain knowledge of BLM planning processes and acronyms like ARMPA, HMA, and ROD.
• Sample data is unavailable, preventing preview of attribute fields and data structure before download.
