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

A 2026 landscape connectivity analysis from the Department of the Interior models moderately-connected habitat corridors for the coastal marten. The dataset represents least-cost corridors with a maximum cost-weighted distance of 45 kilometers, generated using Linkage Mapper software. It was used to create maps for a report categorizing corridor connectivity.

Use Cases

• Mapping habitat corridors for conservation planning based on the described cost-weighted distance model.
• Analyzing landscape connectivity for the coastal marten based on the described least-cost path and corridor methodology.
• Layering multiple corridor datasets to create composite connectivity maps as described for report figures.

Strengths

• Model output is based on a defined maximum cost-weighted distance parameter of 45 kilometers.
• Corridors are derived from a 30-meter pixel resolution resistance surface, suggesting a specific spatial scale.
• Analysis uses established Linkage Mapper methodology (McRae and Kavanagh 2016) for ecological connectivity.

Limitations

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