Lawrence's Goldfinch Range: California Wildlife Habitat Vector Data

Vector datasets from the California Wildlife Habitat Relationships (CWHR) system represent the maximum current geographic extent of species within California. The State of California's Department of Fish and Wildlife maintains this data, last updated in March 2026. Range maps were originally delineated at 1:5,000,000 scale and revised at 1:1,000,000 by species-level experts.

Use Cases

• Model species habitat suitability based on the described geographic range maps.
• Assess land use impacts on wildlife based on the system's stated purpose for impact assessment.
• Support conservation planning based on the dataset's intended use for habitat management.
• Conduct species-level research based on the life history and distribution information in the CWHR system.

Strengths

• Part of a comprehensive state wildlife information system (CWHR) designed for predictive modeling.
• Range maps have been revised from an original 1:5,000,000 scale to a more detailed 1:1,000,000 scale.
• Data is provided in multiple geospatial formats including GeoJSON, KML, and ArcGIS REST API.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description does not specify the exact temporal coverage of the range data.
