Presettlement Vegetation And Vegetational Change In Three Valleys In Central Utah, Earl M. Christensen, Hyrum B. Johnson
Brigham Young University Science Bulletin, Biological Series
Historical information, survey records, and relict vegetation were used as sources of data for determining the nature of the presettlement vegetation of Pavant, Round, and Juab Valleys in central Utah. The foothills were covered with bunch grasses (principally Agropyron spicatum and Poa secunda), scattered junipers (Juniperus utahensis), and sagebrush (Artemisia tridentate). Western wheatgrass (Agropyron smithii) was common on level areas within the foothills.
