This represents the thesis project by Laura A. Welp. Fieldwork was conducted during the summers of 1994 and 1995. The area encompassed the Great Divide Basin, Green Mountains, and Upper Sweetwater Plateau (Carbon, Sublette, and Sweetwater counties) for a total of 5,326 mi2 ranging in elevation from 6,400 to 8,700 feet. Collected were 8,260 specimens documenting 877 unique taxa. An additional of 51“historical” records at RM/USFS raised the figure to 928 total unique taxa. Species of conservation concern were 14 documented at 24 sites. Also vouchered were 75 exotics including eight noxious weeds. Funding was provided by the Bureau of Land Management, Wyoming Native Plant Society, and the University of Wyoming.
