Sonoma Tree Vole Habitat Range in California

A vector dataset representing the maximum current geographic extent of the Sonoma tree vole (CWHR code M132) within California. It is part of the California Wildlife Habitat Relationships system, developed by the State of California to support habitat conservation and land use planning. The range maps were originally delineated at 1:5,000,000 scale and revised to 1:1,000,000.

Use Cases

• Model species distribution for the Sonoma tree vole using the CWHR M132 range polygon for conservation planning.
• Overlay the species range map with land use or vegetation data to assess habitat relationships and management status.
• Integrate the vector dataset into a geographic information system for impact assessment of proposed developments within the vole's range.

Strengths

• Data is part of the authoritative California Wildlife Habitat Relationships system maintained by the State of California.
• Range maps have been revised from an original scale of 1:5,000,000 to a more detailed 1:1,000,000 scale.
• The dataset is designed for use in habitat conservation, land use planning, and impact assessment for terrestrial vertebrates.

Limitations

• The range represents a maximum geographic extent and may not reflect current local population presence or density.
• Data is specific to California and does not cover the species' full potential range outside the state.
