Coastal Marten Landscape Connectivity Analysis with Least-Cost Corridors

Department of the Interior packaged outputs from a secondary landscape connectivity model for the coastal marten. The data includes Extant Population Areas, least-cost paths, and least-cost corridors connecting these populations, generated using Linkage Mapper. The packaged data layers were last updated on March 4, 2026.

Use Cases

• Model habitat connectivity corridors based on least-cost path analysis.
• Analyze potential movement routes for coastal marten populations.
• Plan conservation interventions based on defined Extant Population Areas.
• Integrate connectivity layers into broader landscape management maps.

Strengths

• Includes three distinct, purpose-built geospatial data layers.
• Packaged in multiple formats including a fully-symbolized ArcGIS Pro map.
• Model is based on official USFWS Species Status Assessment population boundaries.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Requires ArcGIS Pro version 2.0 or greater to view the map package.
