I am currently focused on improving our understanding of how forest and rangeland vegetation responds to wildfire; how trees killed by wildfire decay and contribute to wildlife habitat, coarse woody debris, and fuels; and how post-fire management treatments can best be used to reduce threats (e.g., post-fire flooding and erosion, future high severity wildfires) and promote long-term ecosystem recovery. I am also working to evaluate the effectiveness of common forest restoration treatments (e.g., mechanical thinning and prescribed fire) for increasing resilience to fire and climatic variability and promoting biodiversity in fire-prone forest and savanna ecosystems.
- Fire, forest, and restoration ecology
- Climate change
- Response to, and influence of, forest, savanna, and grassland ecosystems on the frequency and severity of natural fire regimes
- Response of forest ecosystems to severe fire events
- Forest management practices that manage potential fire behavior and ecosystem resilience
- Variability of forest structure, composition, and function across environmental gradients
- Influence of climatic variability on tree establishment and growth
- Response of tree growth to climate across species and environmental gradients
- Application of fire and forest ecology for restoring and maintaining ecosystem structure, function, and biodiversity in fire-prone forests and savannas
My past work has included studies of tree growth responses to climatic variability using tree-ring analysis, with a particular emphasis on understanding the dominant climate-related stressors that limit growth of subalpine conifers, and how those dominant stressors differ among species, among geographic regions, and across environmental gradients. I have also studied the long-term effects of different prescribed fire frequencies on overstory structure, understory plant communities, and nitrogen availability in oak savannas and woodlands in Minnesota.
Why This Research is Important
In North America and many other parts of the world, humans have modified natural fire regimes through land use changes, landscape modifications, and active fire suppression, leading to significant changes in the structure, composition, and functioning of fire-prone forest, savanna, and grassland ecosystems. These altered ecosystems are often unsustainable and are now experiencing uncharacteristically severe wildfires that not only produce threats to human health and property (e.g., direct wildfire effects, post-fire flooding and erosion, loss of ecosystem services), but may also produce dramatic and persistent changes in the ecosystems (e.g., conversion of forests to shrubland or grassland). Climate change may enhance these problems by promoting longer fire seasons and more extreme fire weather. Forest managers are increasingly focusing their efforts on forest restoration, seeking to increase forest resilience to disturbances and climate change, promote and maintain biodiversity, and improve the capacity of ecosystems to adapt to change. My work contributes to these efforts by providing basic scientific knowledge about how ecosystems function and respond to disturbances and by assessing the effectiveness and ecological impacts of some of the management treatments used to achieve management objectives.
