Hutton's Vireo Range Map for California Wildlife Habitat

Vector datasets represent the maximum current geographic extent of the Hutton's Vireo bird species within California. These range maps are a component of the California Wildlife Habitat Relationships (CWHR) system, developed to support habitat conservation, land use planning, and wildlife research. The maps were originally delineated at a 1:5,000,000 scale by experts and have been revised at a 1:1,000,000 scale.

Use Cases

• Model species habitat relationships using the CWHR system's predictive framework for the Hutton's Vireo.
• Support conservation planning by analyzing the geographic distribution of Vireo huttoni within California.
• Integrate range map data with other CWHR GIS layers for land use impact assessments.
• Educate on wildlife species using the authoritative range extent for the Hutton's Vireo bird.

Strengths

• Data is part of the authoritative California Wildlife Habitat Relationships (CWHR) system developed by the state.
• Range maps have been revised from an original 1:5,000,000 scale to a more detailed 1:1,000,000 scale.
• Specifically covers the Hutton's Vireo (Vireo huttoni), a bird species regularly occurring in California.

Limitations

• The dataset represents the maximum geographic extent, not necessarily current occupancy or population density.
• Specific data structure details like row count, column names, and sample size are unavailable.
• As a single-species range map, it is limited to the Hutton's Vireo and cannot be used for multi-species analysis without combining other CWHR datasets.
