BLM ID NLCS Historic Wilderness Study Area: Idaho WSA Polygons from 2008

Wilderness Study Areas (WSA) for Idaho BLM as they were in 2008 (POLYGONS). This is a HISTORICAL polygon feature class for WSAs in Idaho BLM. The dataset, provided by the Department of the Interior, includes original WSAs later abolished by the 2009 Omnibus bill and retains inholdings.

Use Cases

• Analyze historical land designation boundaries based on 2008-era Wilderness Study Area polygons.
• Study the impact of the 2009 Omnibus bill on public lands based on the inclusion of abolished WSAs.
• Map land inholdings within historical wilderness areas based on the retained inholding data.

Strengths

• Data is explicitly historical, capturing a specific 2008 snapshot of land designations.
• Includes polygons for both active WSAs and those abolished by a 2009 legislative bill.
• Provided in multiple geospatial formats (GEOJSON, KML, CSV) for flexibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to its 2008 snapshot and subsequent legislative changes.
