I am interested in conservation issues in mountain ecosystems related to human effects on the environment. I generally focus on plant community response to anthropogenic perturbations, including climate change, land use, and introduced species. I am currently modeling high elevation forest response to climatic change to inform long-term monitoring and examining the effects of historic fire frequency and severity on plant community structure and composition.

U.S. Geological Survey – Plant Ecologist, Yosemite Field Station (August 1998 – Present) Worked collaboratively with NPS staff and cooperators to develop a long term monitoring design for wetland meadows. Worked collaboratively with NPS staff and cooperators to develop a vegetation classification and map for Yosemite NP and surrounding lands. Completed a two-year cooperative agreement with the NPS to survey high priority special status plant species, map additional potential habitat, and verify map accuracy. Coordinated the development of a five-year Biological Inventory Plan for the NPS Sierra Nevada Network of parks Supervised a two-year effort to quantify alien plant species abundance and distribution in disturbed areas of Yosemite National Park.   

National Park Service and National Biological Service – Ecologist, Yosemite National Park (April 1992 – August 1998) Implemented a five-year study on recreational pack stock grazing impacts to high mountain meadows. Directed field project to quantify 7 years of montane and 4 years of subalpine conifer fuel deposition. Provided local implementation of a central and southern Sierra Nevada tree demography study of 10 conifer species in five stands in three different ecological settings that included seedling establishment and tree recruitment, growth, mortality, and factors associated with mortality.
