Thesis: Taylor, A. R. 2000. The Vascular Flora of the Upper North Platte River Drainage, Wyoming, v + 97 pp.

This represents the thesis project by Amy Roderick Taylor. Fieldwork was conducted during the summers of 1996, 1997, and 1998. The eastern boundary is circumscribed by the Laramie Range and a line from Mills to Waltman in the north. The western boundary includes the Sierra Madre, Great Divide Basin, and Beaver Rim whereas Saratoga Valley represents its southern extent (Albany, Carbon, Fremont, and Natrona counties) for a total of 7,000 mi2 ranging in elevation from 5,100 to 11,162 feet. Collected were 10,446 specimens documenting 1,047 unique taxa. Penstemon haydenii and Robinia neomexicana var. neomexicana were found new to Wyoming. Species of conservation concern totaled 26 documented at 104 sites. Also vouchered were 101 exotics including 18 noxious weeds. Funding was provided by the Bureau of Land Management, Wyoming Native Plant Society, and the University of Wyoming.
