Extensive winter injury of native wildland shrubs occurred in the Western 

 United States during the winter of 1976-77. Artemisia tridentata was damaged 

 most extensively followed by Ceanothus spp., Arctostaptiylos spp., Purshia 

 spp., and 32 other species of shrubs. The record low precipitation during this 

 period, and consequential low snow cover in areas of normally heavy snow 

 cover, combined with other factors that led to the injury.

The Intermountain Station, headquartered in Ogden, Utah, is one 

 of eight regional experiment stations charged with providing scientific 

 knowledge to help resource managers meet human needs and protect 

 forest and range ecosystems. 



The intermountain Station includes the States of Montana, Idaho, 

 Utah, Nevada, and western Wyoming. About 231 million acres, or 85 

 percent, of the land area in the Station territory are classified as 

 forest and rangeland. These lands include grasslands, deserts, 

 shrublands, alpine areas, and well-stocked forests. They supply fiber 

 for forest industries; minerals for energy and industrial development; 

 and water for domestic and industrial consumption. They also provide 

 recreation opportunities for millions of visrtors each year. 



Field programs and research work units of the Station are main- 

 tained in: 



Boise, Idaho 



Bozeman, Montana (in cooperation with Montana State Univer- 

 sity) 



Logan, Utah (in cooperation with Utah State University) 



Missoula, Montana (in cooperation with the University of 

 Montana) 



Moscow, Idaho (in cooperation with the University of Idaho) 

 Provo, Utah (in cooperation with Brigham Young University) 

 Reno, Nevada (in cooperation with the University of Nevada)
