Least-Cost Paths for Coastal Marten Habitat Connectivity

Linkage Mapper software produced least-cost paths and mosaicked corridors for the coastal marten (Martes caurina humboldtensis). The Department of the Interior created this geospatial dataset to model landscape resistance and connectivity between habitat cores. The dataset was last updated on March 4, 2026.

Use Cases

• Identify priority corridors for conservation based on least-cost path analysis.
• Compare Euclidean distance and cost-weighted distance between habitat cores.
• Map biologically realistic corridor mosaics around single-pixel paths.
• Assess landscape resistance surfaces for species movement models.

Strengths

• Model outputs include three comparable metrics: Euclidean distance, cost-weighted distance, and LCP length.
• Corridor mapping advances beyond basic least-cost path estimation by creating wider, mosaicked corridors.
• Analysis uses a 30-meter pixel resolution for the least-cost paths.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description is abbreviated and incomplete, referring to spatial metadata for full details.
