A climactically-induced increase in wildfires in the Alaskan boreal forest threatens rural indigenous livelihoods, and indicates a need for community involvement in wildfire policy planning. A diverse literature describes community-based natural resource management, but has not been applied to wildfire management. Through three research papers this dissertation investigates conflicts over wildfire management in rural Alaska and considers community participation as a potential solution. The first paper explores the concept of a "community" perspective on wildfire in the Koyukon Athabascan communities of Galena and Huslia. A Q-sort was used to determine shared perspectives, and showed that Koyukon grouped separately...
FY2011Aspen populations are in decline across western North America due to altered fire regimes, herbivory, drought, pathogens, and competition with conifers. Aspen stands typically support higher avian biodiversity than surrounding habitats, and maintaining current distributions of several avian species is likely tied to persistence of aspen on the landscape. We are examining effects of climate change on aspen and associated avian communities in isolated mountain ranges of the northern Great Basin, by coupling empirical models of avian-habitat relationships with spatially-explicit landscape simulations of vegetation and disturbance dynamics (using LANDIS-II) under various climate change scenarios. We are addressing...

The Earth is undergoing climate, environmental and land cover changes at an increasing pace. Monitoring land cover change is crucial as land transitions affects the Earth system's functioning by disrupting biogeochemical cycles such as water and carbon and influencing surface energy exchanges. Within this context, documenting changes in Alaska is paramount because the region has a large global reservoir of carbon stored in its soils and its standing biomass. Under warming scenarios of climate change, Alaska is poised to undergo changes that will turn the region from a carbon sink to a carbon source, an event potentially affecting the entire Earth's system. Remote Sensing provides remarkable datasets to study and...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
