Coastal Marten Habitat Connectivity Model: Well-Connected Least-Cost Corridors

A landscape connectivity analysis for the coastal marten (Martes caurina humboldtensis) produced by the Department of the Interior. This dataset represents least-cost corridors classified as well-connected based on a maximum Euclidean distance of 15 kilometers, generated using the Linkage Mapper tool. The data was last updated on March 4, 2026.

Use Cases

• Mapping well-connected wildlife corridors based on Euclidean distance thresholds.
• Conservation planning for the coastal marten using modeled least-cost corridors.
• Analyzing landscape resistance and connectivity between habitat cores.
• Creating composite linkage maps by mosaicking normalized corridor values.

Strengths

• Dataset is derived from a specific habitat connectivity model using the Linkage Mapper methodology.
• Corridors are classified using a defined Euclidean distance parameter (≤15km).
• Produced by the Department of the Interior, suggesting an authoritative source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial extent are unknown, which may limit suitability assessment.
• The description is truncated, leaving some modeling details unspecified.
