Losses resulting from mortalities caused by the train colli- 

 sions were not used in the analysis as various investigations 

 determined the losses along the original and relocated grades were 

 similar (Flath 1972a, 1972b). Therefore, the mortality caused by 

 collisions with trains along the new grade was considered to be a 

 substitutive loss and not a new loss attributable to the Libby Dam 

 project. 



Combining the various minimum loss estimates for the three 

 impacts attributable to the project (1,364 + 37 +66), a minimum 

 loss of 1,467 white- tailed deer was calculated. Combining the 

 maximum loss estimates (2,046 + 56 + 119), a maximum loss of 2,221 

 was calculated. Thus, from 1,467 to 2,221 white-tailed deer were 

 impacted by the construction of the Libby Dam project. The U.S. 

 Dep. Inter. (1965) estimated 1,450 white-tailed deer were in the 

 area of influence of by the Libby Dam project. The above analysis 

 indicates this was a minimal estimate of the population. 



A qualitative loss estimate of high was assessed due to the 

 large amount of crucial winter range inundated and the number of 

 white-tailed deer impacted. This was based on criteria (a) 

 through (d) on page 9.
