5) Estimated Losses Due to the Project 



- Quantitative loss estimate 



- 5-15 moose were lost due to inundation of the impoundment 

 area and the subsequent reduction in the capability of the 

 habitat to support these animals. 



- 20-40 moose have been lost due to train collisions along 

 the relocated railroad grade during the 13 years since 

 the grade was completed. 



- Qualitative loss estimate - low. 



6) Deviation of Loss Estimates 



The loss due to inundation of habitat was derived by reviewing 

 the available data and using the best information to develop a 

 reasonable loss estimate. Ihis estimate is based strictly on best 

 professional judgment and relates to acreages of habitat lost. 



The loss resulting from relocating the Burlington Northern 

 railroad grade was estimated by multiplying two annual loss esti- 

 mates (1.5 and 3.0 moose/year) by the 13 years since the completion 

 of the new grade, resulting in an estimated loss of 20-40 moose. 

 This annual loss estimate was based on the findings of Flath 

 (1972a) and the fact the railroad grade was located within the 

 riparian zone, a priority habitat of the moose. 



A qualitative loss estimate of low was assessed based on 

 criteria (a) and (b) on page 9. The loss of quality moose habitat, 

 due to inundation and the relocation of the railroad grade, was used 

 in the determination of the impact assessment.
