My research interests are primarily concerned with describing and understanding geographic variation in how plants are adapted to their environments and the implications for management including reforestation, restoration, tree improvement, gene conservation, and responses to climate change. Species of interest include forest trees as well as grasses and forbs used in restoration projects. This research has contributed to guidelines for the movement of plant populations, genetic conservation needs, and natural and managed responses to climate change.
My research group investigates topics spanning the spectrum from fire ecology to fire behavior. Our primary interests are in responses of vegetation to fire in grasslands, savannas, woodlands, and forests. We have on-going research in the Pacific Northwest and California in oak woodlands, mixed-conifer forests, pine woodlands, and coast redwood forests and in the Southeast in longleaf pine ecosystems, Appalachian oak-pine forests, remnant Black Belt prairies, and oak-hickory woodlands in Mississippi.
I am intereseted in research that contributes to better understanding of 1) how resource management, including collaborative efforts, influences the supply of ecosystem goods and services from landscapes, 2) how people and industries use ecosystem goods and services, and 3) how that use affects the well-being of human communities and individuals.
My primary research focus for the past decade has been on elk and mule deer at the Starkey Experimental Forest and Range (“Starkey Project”) and replicate sites throughout the West. Research on elk and mule deer has focused on their responses to land uses and human activities; examples include effects of roads, traffic, recreation, silviculture, prescribed burning, and cattle grazing on nutrition, habitat use, and population distribution.
Basic and applied problems in watershed management and riparian and aquatic ecosystemsInteractions between hydrological, geomorphological, and ecological processes that create, maintain, or modify aquatic and riparian habitatsWays in which these processes either interact with, or are affected by, land-use practicesDeveloping models and decision support tools that synthesize the current knowledge of aquatic and riparian systems into forms that can help inform management decisions at large spatial and temporal scales
Tree physiology, plant stress physiology, impacts of climate change on tree growth, plant/water relations, photosynthetic gas exchange, constraints on tree growth.
My research interests are varied, but revolve primarily around fire ecology, quantifying vegetation as fuel and fire/vegetation dynamics. While I have a particular fondness for the dry forests of the Cascade Range and Blue Mountains in Washington and Oregon, I have also been involved in field studies in a wide variety of ecosystems in more than half of the states spread across the country.
