Southern Grasshopper Mouse Range Map for California

Vector datasets from the California Wildlife Habitat Relationships system represent the maximum current geographic extent of terrestrial vertebrates. This specific dataset contains the range map for the Southern Grasshopper Mouse (CWHR M122), originally delineated at 1:5,000,000 scale and revised at 1:1,000,000. The data supports habitat conservation, land use planning, and research on California's wildlife.

Use Cases

• Model species distribution for the Southern Grasshopper Mouse using the CWHR M122 range map vector data.
• Integrate the range map vector data with other CWHR GIS layers for habitat relationship analysis.
• Assess land use impacts on the Southern Grasshopper Mouse by overlaying the range map with planning boundaries.
• Conduct geographic distribution studies for terrestrial vertebrates using the revised 1:1,000,000 scale vector data.

Strengths

• Data is part of the authoritative California Wildlife Habitat Relationships system developed by the State of California.
• Range maps were originally delineated by species-level experts at a scale of 1:5,000,000.
• Maps have been gradually revised to a more detailed scale of 1:1,000,000.

Limitations

• The dataset represents a maximum geographic extent, not a probability of occurrence or population density.
• Specific temporal coverage for the range map revisions is not provided in the input.
• Data is limited to the geographic boundary of California.
