YCT Multi-state Assessment 



February 10,2003 



Table 7. Look-up table for genetic status of a population segment. 



Genetic Status 



Genetically unaltered (>99.0%) - tested via electrophoresis or DNA 

 Introgressed (hybridized) - tested and found to be 75% to 99% YCT 

 Introgressed (hybridized) - tested and found to be less than 75% YCT 



Potentially unaltered with no record of stocking and contaminating species present 



Suspected hybridized with records of contaminating species being stocked or occurring in 

 stream 



Hybridized and Pure populations exist in stream (use only if reproductive isolation is 

 suspected

For each mapping segment it is important to identify those conservation actions, past or on- 

 going, that have been intended to protect, conserve and enhance each specific population (Table 

 11). It is also important to identity those land-uses (Table 12) that are or maybe exerting 

 negative impacts to the respective mapping segments and the associated habitat. The 

 information on conservation actions and land-use influences will be important as genetic and 

 population risks are assessed.
