Thesis: Kostel, G. M. 2006. A Floristic Inventory of the Buffalo Gap National Grassland (South Dakota) and Oglala National Grassland (Nebraska), vi + 93 pp.


This represents the thesis project by Grace M. Kostel. Fieldwork was conducted during the summers of 2004 and 2005. The area encompassed portions of the western Great Plains (Dawes and Sioux counties, Nebraska; Custer, Fall River, Jackson, and Pennington counties, South Dakota) for a total of 932 mi2 for the Buffalo Gap (BGNG) and 148 mi2 for the Oglala National Grasslands (ONG) (total area 1080 mi2) ranging in elevation from 950 to 4,800 feet. Collected were 11,045 specimens documenting 530 taxa for BGNG and 369 taxa for ONG (together 634 taxa). State records were 17 for Nebraska and 26 for South Dakota. Species of conservation concern for BGNG totaled 19 documented at 68 sites and for ONG totaled 29 documented at 58 sites (combined, 38 at 126 documented sites). Also vouchered were 91 exotics including 6 noxious weeds for BGNG; 55 exotics and 1 noxious for ONG (combined, 146 exotics and 7 noxious weeds). Funding was provided by the Buffalo Gap National Grassland, the Oglala National Grassland, and the University of Wyoming.
