Upper Bulkley Fish and Aquatic Review: Summary of Data, Methodology, Results, and Thresholds for Stream Crossing Density

The Upper Bulkley Fish and Aquatic Review project produced a set of analyses focused on select pressure and quantity indicators as determined by the Wild Salmon Policy Strategy 2. Pressure Indicators included are Road Density, Riparian Disturbance, and Total Land Cover Alteration. Quantity Indicators include Accessible Stream Length. Stream Crossing Density is also included in the analyses but is not an indicator under the Wild Salmon Policy Strategy 2. This report and map provide an overview of stream crossing density. The road and stream crossing data is a derived product from the BC Environment Provincial Stream Crossing Information System (PSCIS). The PSCIS model generates a point data layer representing potential stream crossings cross-referenced to a fish habitat model. The fish habitat model assigns three fish habitat classes to the stream crossings: fish presence – observed, fish presence – inferred, or none.
