Current Research
My research has two central themes:
  1. Adaptating forests to an uncertain climate future
  2. Ecological silviculture based on natural models

Both of these themes are addressed primarily through use of operational-scale management experiments designed to be statistically robust, realistic, but also novel in terms of the treatments examined, and inclusive of a large number of response variables. Much of this work is accomplished through close collaboration with university and agency researchers from across the nation. My particular research foci include questions related to plant biodiversity and community composition, tree regeneration dynamics, and forest productivity. I am interested in tradeoffs between productivity (biomass, volume) and sustainability of other ecological characteristics (e.g., native species diversity and habitat). Ultimately, my interest is in developing and evaluating silvicultural and management approaches that sustain ecological function in managed forests.

Past Research
Some of my past research efforts include:
1. Quantifying disturbances and regeneration processes in longleaf pine woodlands
2. Multi-scale interactions between seasonal wetlands and upland forests
3. Approaches for sustaining functional riparian forests
4. Quantifying natural disturbance regimes in red pine ecosystems
Research Interest
Specific research interests include:
1. Adaptation approaches for wetland black ash forests in the face of emerald ash borer and climate change
2. Adaptive silviculture for climate change (ASCC) in red pine ecosystems--as part of the national ASCC network
3. Assisted migration of future climate adapted tree species in operational forestry settings
4. Thinning/stocking strategies to mitigate impacts of growing season drought
5. Developing a mechanistic understanding of variable retention harvesting and variable density thinning in red pine ecosystems
6. Formalizing an ecological approach to silviculture

Why This Research Is Important

My research on black ash forest response to emerald ash borer and climate change is novel in the research community, as it uses whole-ecosystem manipulation based on natural forest dynamics, as well as stand-scale emulation of EAB mortality.  It is important because results contribute to guidelines and strategies aimed at pre-emptive management of this vast forest type in the face of these threats.

My work on climate adaptation approaches in red pine forests is novel in the research community globally, because it combines long-term silivcultural experiments with large-scale, whole-ecosystem manipulations to examine a wide range of response variables.  This research is important because results are used to help stakeholders develop expectations and approaches for climate change adaptation.

My work on assisted migration of tree species in operational management experiments is novel globally.  It is important because managers need real world information on species choice and expectations for performance.   

My work on natural forest disturbance and development in both longleaf pine and red pine ecosystems has advanced our fundamental understanding of how these forest work.  This research is important because it contributes to models for ecological silviculture aimed at sustaining ecosystem function in managed forests.

My formulation of an ecological approach to silviculture based on natural models is the first of its kind globally.  It is important because increasingly stakeholders are charged with managing forest for timber in ways that ensure sustainability of ecosystems broadly.

Research Highlights

Adapting Black Ash Wetlands to Emerald Ash Borer and Climate Change

Year: 2016
Black ash is a foundational species in the vast wetland forests of the upper Midwest. Loss of black ash from emerald ash borer will profoundly change these forests, while climate change may limit the ability of other tree species to replace black ash. This project is evaluating adaptation strategies...

First Textbook on Ecological Silviculture Serves as Blueprint for the Next Generation of Forestry

Year: 2020
Ecological silviculture is an approach for managing forests based on emulation of natural forest dynamics to sustain the myriad of services forests provide. For the first time, scientists have distilled the concepts of ecological silviculture into a comprehensive guide, the first truly new textbook ...

The Future of Ash Forests in Minnesota

Year: 2013
Ash forests of the Great Lakes region are vulnerable to emerald ash borer (EAB) and climate change. Forest Service scientists are successfully establishing Manchurian ash, an EAB-resistant species, as well as other tree species that are adapted to a warmer climate. The project is providing insight i...

Ecosystem Impacts of Wood Harvests For Biofuel

Year: 2013
Current interest in harvesting typically non-merchantable material for biofuel warrants a closer look at the ecosystem impacts of intensive harvesting. Classic studies of whole-tree harvesting can offer insight into the ecosystem impacts of intenstive harvesting and comparison to ecosystem responses...

Diversity is Key to Restoring Resilience of Iconic Great Lakes Pine Forests

Year: 2013
Mixed-pine forests of the western Great Lakes region contain fewer tree species and fewer age classes than their historical equivalents. Forest Service scientists and their research partners used a functional restoration approach to increase tree diversity and structural complexity in such forests a...

The information provides managers with the information needed to adapt forest to a future cl...

Ecological Limits to Biomass Harvesting

Year: 2014
Removing forest biomass for fuel can provide an alternative to fossil fuels and may mitigate atmospheric carbon dioxide increases, but it may change ecosystem functions. Forest Service scientists and their research partners showed that different levels of removal of forest biomass affect soil and tr...

Assisted Migration of Replacement Tree Species in Black Ash Wetlands

Year: 2015
Black ash is a foundational species of deciduous wetland forests in the western Great Lakes region because of its considerable influence on wetland hydrology and related ecosystem services. Loss of ash trees due to emerald ash borer infestation will profoundly change the function of these ecosystems...

Restoring Forest Landscapes

Year: 2014
An estimated 1 billion acres of globally degraded forest are in need of restoration today and climate change likely will drive more acres into the same condition. Global change, climate variability, biotechnology, and synthetic biology pose significant challenges to current restoration paradigms, un...
