A literature survey has been completed in order to determine plant species that have been considered rare, and also plant species that are potentially rare. Dr. Stan Welsh of the Botany and Range Science Department of Brigham Young University (Provo, Utah) was contacted personally during the field season. His experience in the region has provided a list of additional species that are considered rare for the state of Utah and occur on specific sites near the National Park (Table 1). It is possible that these additional rare species may occur within the boundaries of the park.
