- One hundred deer were removed from Highway 93 between 

 Eureka and Fortine and 25 between Rexford and Warland. 



1970 Trains began using the relocated line through the Fisher 

 River and Wolf Creek winter range. 



Firebaugh (1971) - MDFG 



- Initiated the deer - railroad relationship study along 

 the Fisher River and Wolf Creek (funded by the U.S. Army 

 Corps of Engineers) . 



Speed restriction along the new railroad right-of-way was 

 lifted in January. 



1971 Flath (1972a) - MDFG - continued the railroad - deer re- 

 lationships study. 



- Reported white-tailed deer habitually return to the 

 same area to winter, and identified 3 migration routes 

 onto the Fisher River-Wolf Creek winter range (Fisher 

 River, Little Wolf Creek and Wolf Creek). 



- Estimated 1081 (90% CI: 1005-1157) in the 8.5 square 

 miles of winter range from Butler Creek to Richard's 

 Creek. 



- Observed railroad mortalities of 1.59/mile on the control 

 area and 1.01/mile on the study area. 



Campbell (1972) - MDFG - initiated a study funded by the U.S. 

 Army Corps of Engineers to evaluate potential improvements to 

 big game winter ranges. 



- Fifteen deer (14 mule deer and 1 white-tail deer) were 

 neck banded to study migration patterns. 



- A 1/2 mile strip along the west side of the reservoir 

 from Poverty Creek to the Canadian line was used exten- 

 sively by both mule deer and white-tailed deer. 



- Browse was the most important winter forage class, with 

 Oregon grape, ponderosa pine and Douglas-fir composing 

 97% of the browse consumed. 



1972 Flath (1972b) - MDFG - continued investigations for the rail- 

 road-deer relationships study. 



- Estimated there were 135 deer/square mile on the Fisher 

 River-Wolf Creek winter range. 



- Observed railroad mortalities of 1.65 deer/mile on the 

 control compared to 1.93 deer/mile on the study area.
