Description
Nicole Graham from Borealis Harvested Dataverse created a dataset investigating the intersection of modeled Pacific salmon streams with conserved and protected areas in British Columbia. The analysis, last updated in 2026, uses bcfishpass models to intersect spawning and rearing streams for all Pacific salmon species with various protected area types. It examines stream lengths by species, life stage, and region to understand protections against natural resource extraction.
Use Cases
Assessing the level of protection for salmon habitats from forestry, mining, and oil/gas activities based on the intersection analysis described.
Comparing conservation outcomes for different salmon species and life stages based on the reported stream length distributions.
Prioritizing watersheds for conservation efforts based on the identification of high-stream-length areas like the North Coast Islands.
Evaluating the effectiveness of different protected area types, such as provincial parks and ungulate winter ranges, for salmon habitat conservation.
Strengths
Analysis is based on modeled streams for all Pacific salmon species in British Columbia.
Findings provide specific comparisons, such as Sockeye having notable differences in restriction levels.
Identifies specific high-impact areas, such as the North Coast Islands watershed having the highest stream length for many species.
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.
Data freshness should be verified as the last update timestamp is in the future (2026-05-02).
