Greater Sage-Grouse Conservation Areas For Idaho And Southwestern Montana

Five Greater Sage-Grouse Conservation Areas delineate habitat and management zones for the Idaho and Southwestern Montana Environmental Impact Statement. The dataset, created by the Department of the Interior, integrates administrative draft plans and the Idaho Governor's Conservation Areas. It was last updated in April 2026.

Use Cases

• Summarize habitat acreage and management zone types within each Conservation Area polygon for population impact studies.
• Evaluate disturbance density metrics, such as road or development proximity, across the five Conservation Area boundaries.
• Analyze the spatial relationship between Governor's Conservation Areas, Alternative G Habitat Management Areas, and the final expanded EIS boundary polygons.
• Model adaptive management strategies by comparing habitat features within the Idaho Desert, Mountain Valleys, Southern, West Owyhee, and Southwestern Montana Conservation Areas.

Strengths

• Seamless polygon coverage spans the entire Idaho-Southwestern Montana Greater Sage-Grouse EIS boundary.
• Integrates multiple authoritative sources: Idaho Governor's Conservation Areas and the Administrative Draft Proposed Plan (Alternative G).

Limitations

• Specific row counts, polygon counts, and acreage statistics for each conservation area are not provided.
• The dataset's temporal coverage is fixed to the 2015 planning period and may not reflect current habitat conditions.

Provenance
