List of Tables 



Table 1 . Genetic classes used for assessing genetic status of westslope cutthroat trout in 2002. ..6 



Table 2. Codes and descriptions used for assessing relative abundance of westslope cutthroat 

 trout in 2002 8 



Table 3. Criteria used for designating each conservation population 9 



Table 4. Ranks and descriptions used for assessing genetic risks to designated conservation 

 populations of westslope cutthroat trout in 2002. Hybridizing species includes any 

 introduced species or subspecies, but exclude native species (inland redband and steelhead 

 trout), that could potentially hybridize with westslope cutthroat trout 10 



Table 5. Ranks and descriptions for disease risks to designated conservation populations of 



westslope cutthroat trout in 2002 1 1 



Table 6. Ranks and descriptions of population risks to designated conservation populations of 

 westslope cutthroat trout in 2002 12 



Table 7. Codes and descriptions for conservation activities applied to designate conservation 

 populations of westslope cutthroat trout assessed in 2002 ] 3 



Table 8. Codes and descriptions for management activities that could potentially impact 



designated conservation populations of westslope cutthroat trout assessed in 2002 14 



Table 9. Genetic status for westslope cutthroat trout by stream length (miles) within and outside 

 of their historical range as of 2002 18 



Table 10. Comparison between results from areas that have been genetically tested to those from 

 areas that have not had genetic testing for 17 4'''-code HUC's in Idaho. Bolded percentages 

 within UNTESTED segments indicate predominant genetic status of untested segments 

 where genetic testing had also been done 23 



Table 11. Miles of historical habitats currently occupied by westslope cutthroat trout by genetic 

 status and relative abundance for assessment done in 2002 24 



Table 12. Miles (%) of habitats within historical range that are currently occupied by westslope 

 cutthroat trout by relative abundance classes and data quaUty rating for assessment done in 

 2002 24 



Table 13. Miles of habitats occupied (% of occupied) by westslope cutthroat trout in Forest 



Service designated wilderness and roadless areas and within all federal lands 25 



Table 14. Miles of habitats supporting westslope cutthroat trout that were within Forest Service 

 designated wilderness areas by abundance class for an assessment done in 2002 27 



Table 15. Number and miles of designated conservation populations of westslope cutthroat trout 

 by reason for assigning those populations as conservation populations along with 

 proportions of those populations by number and miles within isolets and metapopulations. 

 29 



Table 16. Ranked risks to designated conservation populations of westslope cutthroat trout that 

 functioned as "isolets", "metapopulations", and combined by number of conservation 

 populations and miles of habitat that these conservation populations occupied by risk factor 

 as of 2002. Bold population composite risk scores are weighted scores for temporal 

 variability, population size, demographics, and isolation re-classified into low to high 

 categories (see Methods for details) 32
