R. L. Hartman, B. E. Nelson

Inventory dates: 2001, 2002, 2003, 2004

This represents a staff project primarily by R. L. Hartman but also B. E. Nelson. Fieldwork was conducted during the summers of 2001, 2002, 2003, and 2004. The area encompassed Valle Grande, Sierra de los Valles, Cerro de la Garita, Sierra deToledo, Cerros de los Posso, Redondo Peak, Redondo Border, and Banco Bonito and a portion of the contiguous Bandelier National Monument (Rio Arriba and Sandoval counties) for a total of 139 mi2 ranging in elevation from 6,354 to 13,770 feet. Collected were 5,182 specimens documenting 562 total taxa. Betula glandulosa, Carex brunnescens subsp. brunnescens, Carex conoidea, Lepidium ramosissimum var. bourgeauanum, and Oryzopsis pungens represent taxa previously unreported for New Mexico. Species of conservation concern totaled 44 and were documented at 89 sites. Also vouchered were 68 exotics and noxious weeds. Funding was provided by the U.S.G.S. Biological Resources Division and the University of Wyoming.
