Current Research

Sarah's current work includes a common garden study that will examine trait differences across populations of key forb species important for restoration (Chaenactis douglasii,  Dieteria canescens, and others). This information will be used to create seed transfer maps for use in sourcing appropriate seed for restoration across the Great Basin.

Past Research

Sarah's past research examines how plants respond to environmental variation. She has conducted seed germination work that shows population-level variation in cues that stimulate germination for several native plant species, a seed bank study looking at environmental predictors of seed bank characteristics, and species distribution modeling that indicates differences in climate-niches across co-existing native plant species.

Why This Research is Important

Sarah's work combines both basic and applied scientific research that is relevent to land management and restoration ecology in arid landscapes. Her research contributes to the broader understanding of the ecology of herbaceous arid land plants, which are an important resource for wildlife and add diversity to native plant communities. More recently, her common garden work will help to create tools that will aid land managers in selecting appropriate seed sources for particular restoration projects.
