Savannah Sparrow Range in California: CWHR B499 Vector Data

Vector datasets from the California Wildlife Habitat Relationships system represent the maximum current geographic extent of species within the state. The CWHR System is a predictive model developed to support habitat conservation, land use planning, and research involving California's terrestrial vertebrates. Range maps for the Savannah Sparrow were originally delineated at 1:5,000,000 and have been revised at a scale of 1:1,000,000 by species-level experts.

Use Cases

• Modeling habitat suitability and species distribution based on maximum geographic extent data.
• Supporting land use planning and impact assessment based on current species range maps.
• Conducting ecological research on wildlife habitat relationships for the Savannah Sparrow.
• Informing conservation management strategies using expert-revised spatial data.

Strengths

• Data is part of a comprehensive state information system (CWHR) for California's wildlife.
• Range maps have been revised from an original scale of 1:5,000,000 to a more detailed 1:1,000,000 scale.
• Maps represent the maximum current geographic extent, providing a consistent baseline for analysis.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
