Native Species Rank •jr ^ . *>;. -t,. 



Native species prioritization incorporated only bull trout and WSCT fields. Scoring 

 criteria weighted heavily towards bull trout and fluvial WSCT presence (Appendix A). Native 

 species scoring and ranking generated 7 classes (Figure 3). High priority project streams (classes 

 1-4) contain 5 lower Blackfoot River bull trout core areas and several tributaries therein. Forty- 

 four of 50 (88%) non-project streams support native species, with high priority (classes 1-5) 

 streams (primarily upper river tributaries) containing bull trout or fluvial WSCT. Non-project 

 class 6 streams (low priority) contain by far the highest number of impaired streams. These 

 streams generally support disjunct resident WSCT populations, located primarily in headwater 

 areas of the Nevada Creek and Union Creek watersheds. Because they lack native WSCT and 

 bull trout, six non-project tributaries ranked in the lowest (7*) priority class (Figure 7).
