—The common, native big sagebrush on this winter range. 



various sources were removed from their native habitats and transplanted into adjacent 

 rows of about 100 plants each on Utah Division of Wildlife Resources deer winter range 

 northwest of Price, Utah (fig. 38) . This kind of planting reduces environmental factors 

 (e.g., soil and climate) that might have a confounding infuence on utilization. 



Although the degree that plants from one source were grazed varied considerably, a 

 strong preference is indicated for group I-type plants as compared to group Il-type 

 plants (table 5, figs. 38 and 39). Older but similar plantings that have been grazed by 

 deer and livestock over a longer period of time substantially confirm these observations 

 We have observed only one instance where grazing animals preferred group II to group I. 

 This exception involved 40 group II plants transplanted from a lowland black greasewood 

 area onto a foothill site having a prevailing group I population. In this instance, 

 deer showed a marked preference for the group II plants. Possibly, the different taste 

 of group II plants in a predominantly group I area attracted the deer.
