Coastal Marten Well-Connected Habitat Corridors Based on Cost-Weighted Distance

A landscape connectivity analysis for the coastal marten (Martes caurina humboldtensis) produced by the Department of the Interior. The dataset represents least-cost corridors classified as well-connected, defined by a maximum cost-weighted distance parameter of 15 kilometers. It was last updated on March 4, 2026, and was used to create maps for a report on habitat connectivity.

Use Cases

• Mapping well-connected habitat corridors for conservation planning based on the 15km cost-weighted distance threshold.
• Analyzing landscape resistance and connectivity for the coastal marten based on the described Linkage Mapper methodology.
• Layering multiple corridor datasets to create composite maps depicting connectivity levels as described for Figures 14, A6.3, and A6.4.
• Studying the relationship between Euclidean distance and cost-weighted distance in wildlife movement models.

Strengths

• Based on a defined and documented modeling process using Linkage Mapper tools.
• Provides a specific, parameterized output (corridors ≤15km cost-weighted distance) for focused analysis.
• Dataset is associated with a formal report from the Department of the Interior, suggesting a research context.

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, missing details on potential parameter limits or model validation.
