Ash-Throated Flycatcher Range: California Wildlife Habitat Vector Data

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for California's wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. Range maps represent the maximum, current geographic extent of each species within California.

Use Cases

• Model species habitat suitability based on the CWHR predictive model system.
• Assess land use impacts on wildlife based on current geographic species extent.
• Support conservation planning based on expert-delineated range maps.
• Conduct species distribution research based on the CWHR information system.

Strengths

• Range maps were originally delineated by species-level experts.
• Maps have been revised at a scale of 1:1,000,000.
• Data is part of a comprehensive state wildlife information system (CWHR).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
