Current Research

• Testing the Effectiveness of Postfire Rehabilitation Treatments in the West -- in collaboration with Forestry Sciences Laboratory, Rocky Mountain Research Station
• Chaparral restoration: feasibility testing
• Native plant materials for southwest California ecoregions -- collaboration with Riverside-Corona Resource Conservation District

Research Interests

Current research interests include testing the effectiveness of emergency postfire slope stabilization treatments such as grass seeding, aerially-applied mulches, and hillslope erosion barriers; examining the response to fire of rare species and their habitats; and examining the effects of fuel treatments on the spread of invasive nonnative plants. New projects look at restoration techniques for chaparral sites that have been largely type-converted to non-native annual plants due to past disturbance or too-frequent fire.

In the future, I will continue studying the effectiveness of new postfire treatments, particularly those that are extremely expensive or controversial with the public, as well as the impacts of treatments on native vegetation recovery and effects on invasive plants.
