Habitat Capacity Models for Sacramento Winter Run Chinook Salmon

Results of GIS models of habitat capacity for Sacramento Winter run Chinook salmon. The project examines the relative importance of multiple aquatic habitats for salmon migration, density dependence influences, and life history variation on extinction risk. Analyses of Skagit Chinook, Oregon coho, and Winter run Chinook are included.

Use Cases

• Modeling salmon extinction risk based on life history variation mentioned in the description
• Evaluating habitat importance for salmon migration based on the analysis of streams, estuaries, and nearshore areas
• Assessing the influence of density dependence on habitat use for different salmon populations

Strengths

• Focuses on three specific salmon populations: Skagit Chinook, Oregon coho, and Winter run Chinook
• Model results are derived from GIS analysis, suggesting spatial data integration

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is provided in PDF format, which may hinder direct computational analysis
