We developed several alternative assessment and modeling approaches for identifying, estimating and ranking tributaries in the Skagit River basin according to their intrinsic ability to support Chinook salmon rearing habitat, which is the major habitat limiting factor for abundance and productivity (Zimmerman et al. in press.) We relied on spawner abundance observations and modeled potential as screening tools given the relationship of spawning and rearing areas as well as data availability and quality relative to limited rearing habitat data. This effort focused on intrinsic habitat potential as opposed to current conditions in an effort to assess the future potential for stream habitat restoration and protection. Recommendations are made for incorporating these tributaries into the Tier 2 Target Area in the Skagit Watershed Council 2010 Strategic Approach.
