This represents a staff project by B. E. Nelson and R. L. Hartman. Fieldwork was conducted during the summers of 1993, 1994, and 1995. The area encompassed plains, grasslands, and breaks (Converse, Goshen, Natrona, Niobrara, and Platte counties) for a total of 19,772 mi2 ranging in elevation from 4,100 to 6,100 feet. Collected were 12,617 specimens documenting 958 unique taxa. State records included: Eleocharis parvula, Eragrostis spectabilis, Juncus articulatus, Scirpus saximontanus, and Spiranthes diluvialis. Species of conservation concern were 15 documented at 66 sites. Of special note was the federally listed threatened species Spiranthes diluvialis collected at two sites which represented a state record. Also vouchered were numerous exotics including 17 noxious weeds. Funding was provided by the Bureau of Land Management and the University of Wyoming.
