Education

Ph.D., Biological Sciences, Wayne State University, Detroit, MI, 1986
M.S., Range Science, Brigham Young University, Provo, UT, 1981
B.S., Botany, Brigham Young University, Provo, UT, 1978

Background

Rosemary's decision to follow a career in botany reflected her interests in flowers and the outdoors. As an undeclared biology major at BYU, she explored various options before deciding to focus on plant research. She began her Forest Service career in 1978 as a Youth Conservation Corps crew leader and later served as a biological technician on a mineland reclamation project at the Shrub Sciences Lab. Rosemary joined the Rocky Mountain Research Station in Provo, UT in 1986 (when it was known as the Intermountain Research Station). Her primary focus is plant reproductive biology. At the Shrub Lab, she worked with Grassland, Shrubland and Desert Ecosystem Program Manager Durant McArthur on various projects, including reproductive biology of Zuckia, Linum, and Purshia, and the effects of biological soil crusts on plant establishment. She served as Adjunct Assistant Research Professor of Botany and Range Science at Brigham Young University from 1986 to 2000. She and her husband, Burt, also a research ecologist with the Rocky Mountain Research Station, transferred to the Albuquerque Lab in 2000.

Current Research Interests

Current research focuses on community dynamics at the grassland/shrubland ecotone. Recent and on-going studies and projects include:

  • Effect of fire on grassland vegetation and soil properties, including perennial grass recovery, biodiversity, floral resources for pollinators, soil microtopography and biological soil crust function.
  • Biology and control of cheatgrass in the Southwest
  • Reproductive biology and gene flow in creosote bush (Larrea tridentata) at the northern ecotone.

Previous Research

  • Reproductive biology of perennial blue flax (Linum perenne), bitterbrush (Purshia tridentata), and other associated species.
  • Use of fire as part of an integrated management plan for control of yellow starthistle (Centaurea solstitialis).
  • Team publication of the station GTR Assessment of Grassland Ecosystem Conditions in the Southwestern United States.
