BLM Montana Dakotas GRSG ROD ARMPA: Greater Sage-Grouse Habitat Management Areas

The dataset delineates habitat management areas for Greater Sage-Grouse across Montana, North Dakota, and South Dakota, reflecting updates from a 2015 process and incorporating new scientific modeling. It was created by the Department of the Interior's Bureau of Land Management, with the last update recorded on March 7, 2026. The data identifies Priority, General, Connectivity, and specific local habitat management areas to balance conservation with resource development.

Use Cases

• Modeling habitat connectivity corridors for Greater Sage-Grouse based on the defined Priority Habitat Management Areas (PHMA).
• Assessing land-use conflicts between wildlife conservation and mineral development within the South Carter and Little Missouri Habitat Management Areas.
• Planning habitat restoration efforts in areas identified as General Habitat Management Areas (GHMA) with potential for seasonal occupancy.
• Analyzing cross-border ecological processes and population connectivity using the defined Connectivity Habitat Management Areas (CHMA).

Strengths

• Incorporates updated state information and new range-wide habitat modeling from post-2015 science.
• Includes multiple specific management area types (PHMA, GHMA, CHMA, LMHMA, SCHMA) responding to local and rangewide priorities.
• Available in multiple geospatial formats (GeoJSON, KML, GDB) for interoperability with various GIS tools.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Bureau of Land Management's jurisdiction and planning area.
