a. to determine weight change of elk and cattle under 

 various forage conditions during the winter months; 



b. to compare food requirements of elk and domestic 

 cattle; 



c. to establish food habit characteristics of elk on a 

 free choice basis. 



2. To rate various important forage plants for use in inventory 

 work on elk winter ranges. 



3. To compare nutritional values of various types of feed avail- 

 able on elk winter ranges. 



The inforniation being obtained from this project has represented 

 an important basis for the determination of the carrying capacity of 

 the Fish and Game Commission's more important winter elk ranges, 

 particularly the Sun River. 



FACTORS INFLUENCING SURVIVAL OV RELEASED CHUKARS 



Objectives: 



1. To contribute to the knowledge of the life history of the 

 chukar partridge. 



2. To obtain survival, reproduction and dispersal information on 

 spring and fall releases. 



3. To attempt to determine when and under what conditions 

 chukar releases are most likely to prove successful. 



The findings of this project are of particular importance to the 

 Montana Fish and Game Commission in planning the introduction of 

 this species of upland game bird in the State. 



LIFE HISTORY AND ECOLOGY OF MARTEN IN GLACIER PARK 



Objectives: 



1. To gather data on the life history of this very important fur 

 bearer. 



2. To determine population density and turnover, dispersal, range 

 movement and distribution of marten by means of live 

 trapping and tagging. 



3. To correlate marten density with vegetation types and food 

 supply. 



The information being gathered from this project has immediate 

 application in the management and restoration of the marten 

 throughout desirable mountain ranges in the State.
