BICiHORN SHEEP STUDY 



Objectives: 



1. To determine the population growth and productivity of the 

 Wildhorse Island bighorn sheep population. 



2. To measure and evaluate lamb and yearling survival. 



The findings from this project have been of particuhir interest 

 and value to the management of bighorn sheep not only on Wihlhorse 

 Island but on the several additional important ranges throughout the 

 State. This work also indicated the availability of bighorns from this 

 particular range for transplanting purposes in the development of 

 new herds. 



BIOLOGY OF CANADIAN GEESE IN THE FLATHEAD 

 VALLEY OF MONTANA 



Objectives: 



1. To determine the total nesting population of Canada geese 

 in the Flathead Valley by means of aerial and ground census 

 techniques. 



2. To determine productivity of Canada geese in the Flathead 

 Valley through extensive population survey and intensive 

 nesting studies in areas of high nesting concentrations. 



3. To determine factors affecting nesting densities such as 

 habitat and human activity. 



4. To evaluate environmental resistance factors including 

 weather conditions, water levels and predation. 



5. To gather information on local and migratory movements of 

 geese in the area through banding and field observations. 



6. To determine total kill by hunters of geese in the area and to 

 obtain information on hunting pressure. 



In working out the answers to the various a.sp«*cts of this pro- 

 gram, the I'nit has work<>d very <'losely with Fish and (iame Depart- 

 ment personnel. Findings have been and will <(tntinue to be of ex-
