Island Gray Fox Species Range Map for California

California Wildlife Habitat Relationships (CWHR) provides a vector dataset representing the maximum current geographic extent of the Island Gray Fox species within California. Range maps were originally delineated at 1:5,000,000 scale by species experts and revised at 1:1,000,000 scale to support habitat conservation and land use planning.

Use Cases

• Model Island Gray Fox habitat suitability by analyzing the species range map geometry against environmental layers.
• Assess land use impacts by overlaying the CWHR range map with proposed development or conservation area boundaries.
• Support wildlife research by integrating the species distribution data with life history accounts from the CWHR system.

Strengths

• Data is part of the California Wildlife Habitat Relationships system, a predictive model for the state's terrestrial vertebrates.
• Range maps were developed and revised by species-level experts, ensuring authoritative delineation.
• Spatial data is available at a revised scale of 1:1,000,000, offering detailed geographic representation.

Limitations

• The dataset represents the maximum geographic extent, not probability of occurrence or habitat suitability within that range.
• As a single-species range map, it lacks the multi-species or community-level data needed for broader ecological analyses.
• Data is specific to California, limiting applicability for studies of the species' full range outside the state.
