Current Research

1) The Season and Interval of Burn Project: Lead Scientist; 2) Fire and grazing interactions in ponderosa pine forests; 3) Interactions between fuel reduction, weeds, and seeding treatments in juniper woodlands; 4) Invasive species and climate change; 5) Response of Pacific Northwest vegetation to climte change; 6) Creating climate informed state-and-transition models using a dynamic global vegetation model.

Research Interests

I work to increase our understanding of how natural and human-caused disturbances and their interactions structure vegetation and plant communities. I conduct my research at multiple biological, spatial, and temporal scales using empirical, experimental, and landscape modeling approaches.

Past Research

My past work has studied nontimber forest products, phytolith analysis, paleoecology, and geomorphology.

Why This Research is Important

Forests and rangelands are dynamic systems subject to a variety of disturbances, both natural and human-caused. These disturbances shape their composition and function and dictate, to some extent, the ecosystem services that are provided. Disturbances are a normal, necessary, and desired part of ecosystem dynamics. Human-caused disturbances may be unintentional or intentional and designed to effect a change in system function or to produce desired goods and services (e.g., timber harvest), but both may result in unanticipated and undesirable consequences, such as erosion, debris flow, and air pollution.
