Coastal Marten Habitat Connectivity: Moderately-Connected Least-Cost Corridors (≤45km)

A 2026 dataset from the Department of the Interior containing geospatial data on moderately-connected habitat corridors for the coastal marten (Martes caurina humboldtensis). The data was generated using a landscape resistance surface and the Linkage Mapper tool to identify least-cost paths and wider corridors between habitat cores, with a maximum Euclidean corridor distance parameter of 45 kilometers. It was used to produce maps for a report on landscape connectivity.

Use Cases

• Mapping habitat corridors for conservation planning based on the least-cost corridor model.
• Analyzing landscape connectivity for the coastal marten based on Euclidean and cost-weighted distance parameters.
• Creating composite linkage maps by layering datasets for well-connected, moderately-connected, and poorly-connected corridors.
• Assessing the impact of landscape resistance on corridor width and connectivity potential.

Strengths

• Data is derived from a defined habitat connectivity model using Linkage Mapper, a standard tool in conservation science.
• Corridors are classified based on a specific, documented Euclidean distance threshold (≤45km).
• The dataset is part of a structured analysis for a formal report, suggesting a defined methodological context.

Limitations

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