Thesis: Ebertowski, P. J. 2005. A Floristic Inventory of the Vascular Plants of the Thunder Basin National Grassland and Vicinity, Wyoming, iv + 76 pp.

This represents the thesis project by Peter J. Ebertowski. Fieldwork was conducted during the summers of 2002 and 2003. The area encompassed Great Plains grasslands, river drainages, and breaks (Campbell, Converse, Crook, Niobrara, and Weston counties) for a total of 8,803 mi2 ranging in elevation from 3,500 to 5,700 feet. Collected were 10,013 specimens documenting 673 unique taxa. An additional of 128 “historical” records at RM/USFS raised the figure to 801 total unique taxa. Species of conservation concern totaled ten documented at 35 sites. Also vouchered were 110 exotics including 15 noxious weeds. Funding was provided by the Medicine Bow-Routt National Forest and the University of Wyoming.
