Sue Phillips

I've been with the USGS since 1997, working as a manager, supervisory biologist and now FRESC's Center Director. 

Before joining FRESC's management team, my research focused on the plant, soil, and physiological ecology of arid and semiarid ecosystems, primarily those of the southwestern U.S., but also Africa, the Middle East, Australia, Ecuador, and central Mexico. Before joining the USGS, I spent eight years as a Research Associate at the University of Utah, where I received my M.S. in Plant Physiological Ecology. I received my B.S. in Biology in 1986 from the University of Colorado and worked as a field and lab assistant, then Long Term Ecological Research (LTER) sub-project manager, at the Institute of Arctic and Alpine Research.

Annotated Bibliography of Scientific Research on Greater Sage-Grouse

The greater sage-grouse has been a focus of scientific investigation and management action for the past two decades. The sheer number of scientific publications can be a challenge for managers tasked with evaluating and determining the need for potential updates to existing planning documents.

Integration and tradeoffs

Managing for sagebrush ecosystems that are resilient to disturbance and resistant to invasive plants often requires managers to make tough decisions in the face of considerable complexity and uncertainty.

Insights from long-term ungrazed and grazed watersheds in a salt desert Colorado Plateau ecosystem

Dryland ecosystems cover over 41% of the earth’s land surface, and living within these important ecosystems are approximately 2 billion people, a large proportion of whom are subsistence agropastoralists. Improper grazing in drylands can negatively impact ecosystem productivity, soil conservation, hydrologic processes, downstream water quantity and quality, and ultimately human health...

Soil moisture and biogeochemical factors influence the distribution of annual Bromus species

Abiotic factors have a strong influence on where annual Bromus species are found. At the large regional scale, temperature and precipitation extremes determine the boundaries of Bromus occurrence. At the more local scale, soil characteristics and climate influence distribution, cover, and performance. In hot, dry, summer-rainfall-dominated deserts (Sonoran, Chihuahuan), little or no...

From bacteria to elephants: Effects of land-use legacies on biodiversity and ecosystem structure in the Serengeti-Mara ecosystem: Chapter 8

Generally, ecological research has considered the aboveground and belowground components of ecosystems separately. Consequently, frameworks for integrating the two components are not well developed. Integrating the microbial components into ecosystem ecology requires different approaches from those offered by plant ecology, partly because of the scales at which microbial processes...
