Thesis: Moore, L. M. 1998. Floristics of the Upper Dolores River Drainage and Adjacent Areas, Southwestern Colorado, x + 160 pp.

This represents a thesis project by Lynn M. Moore. Fieldwork was conducted during the summers of 1994, 1995, and 1996. The area encompassed the San Miguel, Rico, and La Plata mountains, Paradox, Big Gypsum, and Disappointment valleys, and adjacent mesas, canyons, and table lands (Dolores, Montezuma, Montrose, and San Miguel counties) for a total of 2,892 mi2 ranging in elevation from 4,940 to 14,246 feet. Collected were 9,600 specimens documenting 976 unique taxa. The following represent species previously not reported for Colorado: Nama retrorsum and Tridens muticus var. muticus. Species of conservation concern totaled 23 documented at numerous sites. Also vouchered were 90 exotics and noxious weeds. Funding was provided by the San Juan National Forest, Bureau of Land Management, Colorado Natural Heritage Small Grants Program, and the University of Wyoming.
