R. L. Hartman, B. E. Nelson

Inventory dates: 1979, 1980

This represents a staff project by R. L. Hartman and B. E. Nelson. Fieldwork was conducted during the summers of 1979 and 1980. The area encompassed the Big Horn Mountains including Cloud Peak Wilderness (Big Horn, Johnson, Natrona, Sheridan, and Washakie counties) for a total of 3,689 mi2 ranging in elevation from 3,800 to 13,165 feet. Collected were more than 8,000 specimens documenting 1,100 unique taxa. Eriogonum mancum was found to be a Wyoming record. Cymopterus williamsii was described as new to science and found to occur in the southern portion of the mountains. Species of conservation concern totaled six at numerous sites. Funding was provided by the Big Horn National Forest, L. O. Williams, and the University of Wyoming.
