Effects of land management practices on plant population and community ecology; effects of air pollutants on plants; chemistry of fogwater; fire ecology.
My research interests focus on effects of human activities on plants.I study
effects of alternative logging methods on forest productivity and diversity
I also study effects of air pollutants on plants in the field and in controlled
environments.
I am working with two graduate students to assess consequences of various fuel reduction methods for native and exotic plants in oak woodlands and shrub lands of SW Oregon. We are also carrying out "historical sleuthing," to try to understand pre-European settlement conditions of vegetation in this area and to learn what, if any, changes in vegetation have been caused by fire suppression in the area.
My current research also focuses on the commercial moss harvest industry in Appalachian and PNW forests.
