I am a terrestrial ecologist who uses quantitative and experimental approaches to address questions about plants and their ecologies. I am primarily interested in processes and interactions that occur at the community level. Most of my current research focuses on the ecology of California prairies (= "valley grasslands"), a complicated and spectacularly beautiful vegetation type. Although my research sometimes involves greenhouse experimentation, most of my data collection is done at field sites in the Carrizo Plain National Monument, a 254,000 acre prairie preserve in eastern San Luis Obispo County. My students and I are examining relationships between native and invasive alien plant species as well as interactions between these plants and various animals (e.g. giant kangaroo rats, valley pocket gophers, pronghorn antelope). We are also studying how disturbances (fire, animal burrowing and livestock grazing) affect vegetation composition over time. Other interests include seed ecology (dormancy and dispersal), phytogeography, Mediterranean-type ecosystems and environmental history. Because of the relevance of my research to conservation and ecological restoration, I frequently interact with government agencies about habitat management. I also strive to educate the public about the importance and immediacy of conservation and environmental preservation issues. Lastly, and perhaps most of all, I am a natural historian and am fascinated by biodiversity. So, I spend a lot of time exploring and thinking about wildness.
