Thesis: Chumley, T. W. 1998. A Floristic Inventory of the East Slope, Central Colorado, viii + 183 pp.


This represents the thesis project by Timothy W. Chumley. Fieldwork was conducted during the summers of 1995, 1996, and 1997. The area encompassed the southern end of the Front Range, including the Rampart Range and Kenosha, the Tarryall and Platte River mountains, the east slope of the Mosquito Range, South Park, and the north slope of the Arkansas River Valley (Douglas, El Paso, Fremont, Jefferson, Park, and Teller counties) for a total of 4,784 mi2 ranging in elevation from 5,500 to 13,000 feet. Furthermore, Ribes niveum was rediscovered for Colorado. Collected were 18,680 specimens documenting 1,075 unique taxa. An additional 304 “historical” taxa at the RM/USFS raised the total unique taxa to 1,379. Species of conservation concern totaled 35 taxa documented at 101 sites. Also vouchered were 104 exotics and noxious weeds. Funding was provided by the Pike and San Isabel National Forest, Colorado Natural Areas Program Small Grants Program, Colorado Native Plant Society, and the University of Wyoming.
