Reu Site: Explore It! Building The Next Generation Of Sustainable Forest Bioproduct Researchers, David Neivandt, Darrell W. Donahue

University of Maine Office of Research Administration: Grant Reports

The major goal of the project is to create the next generation of sustainable forest bioproduct researchers through providing them with an outstanding and relevant research experience.

Reu Site: Explore It! Building The Next Generation Of Sustainable Forest Bioproduct Researchers, David J. Neivandt, Darrell W. Donahue

University of Maine Office of Research Administration: Grant Reports

This three-year REU Site program builds on the substantial research strengths at the University of Maine. The focus on sustainable forest bioproducts is highly topical and of great global importance in the area of sustainable energy alternatives.

Ten US undergraduate participants will conduct research advancing their knowledge of the field in general and one of the thematic elements in detail, specifically:

1) sustainability and life cycle analysis,
2) feedstock extraction/modification,
3) process control and sensing,
4) nanomaterial production and utilization, and
5) new product development. In addition the program includes an international component whereby, six Chilean students on a mutual …

Information And Entropy Theory For The Sustainability Of Coupled Human And Natural Systems, Audrey L. Mayer, Richard P. Donovan, Christopher W. Pawlowski

College of Forest Resources and Environmental Science Publications

For coupled human and natural systems (CHANS), sustainability can be defined operationally as a feasible, desirable set of flows (material, currency, information, energy, individuals, etc.) that can be maintained despite internal changes and changes in the environment. Sustainable development can be defined as the process by which CHANS can be moved toward sustainability. Specific indicators that give insight into the structure and behavior of feedbacks in CHANS are of particular interest because they would aid in the sustainable management of these systems through an understanding of the structures that govern system behavior. However, the use of specific feedbacks as monitoring …

The Community Economic Impacts Of Large Wildfires: A Case Study From Trinity County, California, Emily Jane Davis, Cassandra Moseley, Max Nielsen-Pincus, Pamela J. Jakes

Environmental Science and Management Faculty Publications and Presentations

Wildfires are increasing in severity and frequency in the American West, but there is limited understanding of their economic effects at the community level. We conducted a case study of the impacts of large wildfires in 2008 in Trinity County, California, by examining labor market, suppression spending, and qualitative interview data. We found that the 2008 fires had interrelated effects on several economic sectors in the county. Labor market data indicated a decrease in total private-sector employment and wages and an increase in public-sector employment and wages during the summer of 2008 compared to the previous year, while interviews captured …

Development And Evaluation Of High Resolution Simulation Tools To Improve Fire Weather Forecasts, Brian K. Lamb, Jason M. Forthofer, Peter R. Robichaud

JFSP Research Project Reports

Fire weather forecasts rely on numerical weather simulations where the grid size is 4 km x 4 km or larger. In areas of complex terrain, this model resolution will not capture the details of wind flows associated with complicated topography. Wind channeling in valleys, wind speed-up over mountains and ridges, and enhanced turbulence associated with rough terrain and tall forest canopies are poorly represented in current weather model applications. A number of numerical wind flow models have been developed for simulating winds at high resolution; however, there are limited observational data available at the spatial scales appropriate for evaluating these …

Exploring How Deliberation On Scientific Information Shapes Stakeholder Perceptions Of Forest Management And Climate Change, Troy E. Hall, Jarod J. Blades

JFSP Research Project Reports

Climate change has resulted in rapid biophysical changes in forests of the western U.S. and has prompted the need for an increased understanding of potential impacts and adaption measures. Land managers, policy makers, and community officials lack locally relevant climate change science and are urgently calling for research to inform management decisions. Nevertheless, a substantial disconnect remains between emerging scientific information and its application in management decisions. Effective action depends on understanding regional and local implications of climate change and open, reasoned discussions about current research and potential mitigation actions among researchers, land managers, and other stakeholders. Boundary objects have …

Fire Effects On Seedling Establishment Success Across Treeline: Implications For Future Tree Migration And Flammability In A Changing Climate, F. S. Chapin Iii, Teresa N. Hollingsworth, Rebecca E. Hewitt

JFSP Research Project Reports

Understanding the complex mechanisms controlling treeline advance or retreat in the arctic and subarctic has important implications for projecting ecosystem response to changes in climate. Changes in landcover due to a treeline biome shift would alter climate feedbacks (carbon storage and energy exchange), ecosystem services such as wildlife and berry habitat, and landscape flammability. Wildfire frequency and extent has increased in the last half-century in the boreal forest and tundra in response to warmer weather and lower precipitation. Invasion of tundra by trees may be facilitated by wildfire disturbance, which exposes new seedbeds, increases nutrient availability immediately post-fire, and creates …
