Ecosystem processes and restoration

My current research focuses are: 1. Invasive species treatment options as alternatives to chemical use (i.e., biocontrol (fungal, insects, goats), adaptive manual removal techniques), 2. Restoration of disturbed forests due to invasive species and land use impacts, 3. Importance of wood contributions to soil carbon pools and fluxes, and 4. Soil sustainability and land use. My training is in processes related to forested ecosystem carbon storage. I've examined changes in carbon storage related to forest age (Wyoming, USA), the influence of nitrogen-fixing tree species (Hawaii and Puerto Rico, USA), and coarse root production and soil differences (Tasmania, AUS).

Invasive species in the Keweenaw

As the coordinator of the KISMA and with state of Michigan and US Forest Service and Great Lakes Restoration Initiative funding, I am working with the KISMA community to control new and spreading invasive species across land ownership boundaries and ecosystems and restore native plant communities.
