Current Research

I focus on two types of research: Basic; and Applied.  Both forms of research are important. Basic research provides important information about the structure and function of an ecosystem, and how ecosystems respond to different environmental stresses such as climate change and air pollution. Applied research takes our understanding of ecosystem structure and function from basic research and uses this information to develop adaptive management strategies to ecosystem risk and improve ecosystem function.

My basic research includes understanding how nitrogen and sulfur deposition along with climate change can impact high elevation spruce fir forests, nutrient and water use and yield from forest it watersheds, and understanding ecosystem risk at the regional to continental scale through field experiments and ecosystem modeling.

By applied research includes developing that can assess ecosystem stress and provide land managers with options for correcting reducing or preventing negative impacts stress to their forest, agricultural, range land environments.

Research Interests

Adaptative management strategies for increasing ecosystem and working land resilience to climage change and variabilty.

Why This Research is Important

This research is designed to be useful for management of forest and range lands given the increasing variability of climate in both the short and long-term. Future working land sustainability depends to the choices that land managers are making today, and these studies will give the tools and information needed to make informed decisions.

Professional Experience

Director, USDA Southeast Climate Hub
2014—Current

The objective of the USDA Southeast Climate Hub is to develop and distribute tools, information and resources that will increase the resiliency of working lands (i.e., agriculture, forestry, and range) to disturbance (e.g., drought, insect, disease, frost, flood, hurricane) associated with climate variability and change, to improve the long-term sustainability and productivity of these lands.

Research Ecologist, USDA Forest Service
1991—Current

Since 1991 I have been a research ecologist with a specialty of climate variability and change impacts and interactions with forests. Some of my areas of study include landscape to regional scale nitrogen, water, insect outbreak, and carbon modeling. Increasing our ability to predict non-antecedent forest disturbances is another area of study. This work is done in conjunction with my role as director of the USDA Southeast Climate Hub.

Research Assistant, University of New Hampshire, Durham
1987—1991

As a research assistant, I conducted a regional soil and foliar sampling of 164 red spruce (Picea rubens) plots across a nitrogen deposition gradient from New York to Maine. Additionally, in 1988 I established a long-term (1988 to present) set of field plots in the spruce zone of Mt. Ascutney Vermont to examine the impacts of low dose nitrogen additions on forest health. These experiments demonstrated that low doses of nitrogen could induce nitrogen saturation and that after 30+ years, climate change is impacting the regeneration, productivity, carbon and nitrogen cycling of New England spruce forests.

Research Assistant , University of Wisconsin, Madison
1984—1987

Studied forest water, carbon, and nitrogen cycling at the UW Arboretum and on the UW Blackhawk Island research site. Results from this work were used in some of the earliest hyperspectral remote sensing research.

Research Highlights

Climate Risk Assessment Aids Natural Resource Professionals in the Southeast (2016)
SRS-2016-179 USDA's Climate Hubs deliver science-based, region-specific information and technologies to assist farmers and forest managers with climate-smart decision making. The Southeastern Regional Climate Hub developed an assessment of climate change vulnerability and adaptation and mitigation strategies for natural resource professionals in the southeast.

Fertilized Pines Use Water More Efficiently But May Suffer Worse in Droughts (2015)
SRS-2015-235 Fertilized loblolly pine trees produce more wood than their unfertilized counterparts, even when less water was available, butthis may also indicate that fertilized pine plantations are more vulnerable to severe drought.

High Forest Productivity Often Comes at the Expense of Soil Carbon Storage (2015)
SRS-2015-250 Forest Service scientists and their research partners are studying the role of managed forests in regional carbon, water, and energy exchange to understand how managed forests contribute to land-atmosphere feedbacks and climate dynamics.

Hub Helps Landowners "SERCHing" for Climate Change Answers (2014)
SRS-2014-164 Land managers face new challenges every year from the growing effects of climate change. The regional livelihoods of farmers, foresters, and ranchers depend on the ability of the scientific community to design means of adaptation and effectively communicate those means at management relevant scales. Through a series of webinars and a myriad of other outreach efforts, the USDA Southeast Regional Climate Hub (SERCH) is engaging land managers, extension specialists, and researchers in a mission to understand the climate information needs in the land management community and then translate those needs back into tools and products that help prepare our working lands for future challenges.

Hurricane Preparedness and Recovery Guides for Southeastern Forests, Farms, and Ranch Producers (2020)
SRS-2020-34 A single hurricane can cause more than $1 billion in agricultural and forestry losses, and the intensity of hurricanes is increasing due to climate change. The USDA Southeast Climate Hub developed a series of 23 hurricane preparation and recovery commodity guides for southeastern forests, farms, and ranches. The goal of these guides is to reduce economic loss and increase the reliability of food and fiber supplies from the region.

TACCIMO Development Team Honored with Regional Forester's Honor Award (2011)
SRS-2011-24 The Template for Assessing Climate change Impacts and Management Options (TACCIMO) development team, composed of researchers from the Southern Research Station Eastern Forest Environmental Threat Assessment Center (EFETAC) and planners from the Southern Region, was honored with the Regional Forester's Technology Transfer Award. TACCIMO is a web-based tool designed to bring the best climate change science to decision makers and planners in a simple and usable format. The award acknowledges the team's sustained dedication to addressing the challenge of delivering climate change science to support land and resource planning and management decisions.
