No studies or inventories of wildlife have 

 been made on the two study watersheds, but 

 several comments based on general observa- 

 tions seem appropriate. 



The two watersheds serve as summer range 

 for an unknown number of mule deer. Hunt- 

 ing pressure is heavy, primarily due to the ac- 

 cessibility of the area and the close proximity 

 to high population areas along the Wasatch 

 Front. Winter range of these animals is restric- 

 ted to the lower elevations both to the east 

 and west of the watersheds. 



Beaver are quite active throughout the 

 Farmington Canyon drainage. There are many 

 small dams and three active lodges, one on the 

 East Branch and two on the West Branch. 

 These dams have a profound effect on sedi- 

 ment measurements by alternately trapping 

 and then suddenly releasing prodigious 

 amounts of these materials when dams fail. 

 Any increased sediment caused by the recom- 

 mended treatments of this study probably 

 will be too small to be detected. 



No trout have been found above the 

 stream-gaging stations; this is probably due to 

 the very low summer flows and associated 

 high-water temperatures. Trout are regularly 

 stocked in lower Farmington Creek and fish- 

 ing pressure in the accessible reaches is fairly 

 heavy for such a small stream. 



Pocket gophers are among the more com- 

 monly observed rodents inhabiting the two 

 watersheds. Their presence is marked by the 

 many tunnel castings remaining after snow- 

 melt and the freshly turned mounds of earth. 

 Past research has indicated that if the aspen 

 overstory is removed, pocket gophers may 

 seriously deplete the remaining plant cover 

 (Marston and Julander 1961). 



Our study contains few observations on 

 the bird populations of the area. Ruffed 

 grouse and red-tailed hawks are known to be 

 resident, and bald and golden eagles have been 

 observed in winter. 



A more precise inventory of the wildlife of 

 the area is needed to measure the impact of 

 our proposed treatment on this resource.
