Aquatic Ecological Flows Project Update
-
This presentation from Dr. Todd Walter of Cornell University provides an update to the Steering Committee on the Appalachian LCC funded research project. The Aquatic Ecological Flows project is providing a report assessing availability of hydrologic and ecological flow model(s) suitable for the region, a georeference assessment of available ecological data to inform the ecological flow model(s), the application of the model(s) to anticipate how altered flow regimes will affect critical conditions, and a report that forecasts changes in hydrology and associated predicted biological responses in relation to different water resource development scenarios for critical watersheds.

Stream Impacts from Water Withdrawals in the Marcellus Shale Region

Environmental Flows from Water Withdrawals in the Marcellus Shale Region
-
The Appalachian LCC collaborated with Cornell University to study the environmental impacts of water withdrawals in the Central Appalachian region. The rivers and streams of the Central Appalachians are home to more than 200 species of fish and other aquatic life. They also provide a reliable source of drinking water, recreational opportunities and associated economic benefits to people living in large cities and surrounding communities. This research looks at how the region’s surface freshwater supply – and the health of natural systems delivering this resource – have been impacted and may be altered in the coming years under increasing water withdrawals. It focuses on the Marcellus Shale region in the Central Appalachians, including portions of NY, PA, OH, MD, WV and VA.

Climate Simulations for Southeast and Appalachians
-
A DOI Southeast Climate Science Center funded research project will be evaluating the latest generation of global climate models to generate scenarios of future change to climate, hydrology, and vegetation for the Southeastern U.S. as well as the entire range of the Appalachian LCC.

Assessing Future Energy Development Across the Appalachians
-
Assessing Future Energy Development across the Appalachian LCC used models that combined data on energy development trends and identified where these may intersect with important natural resource and ecosystem services to give a more comprehensive picture of what potential energy development could look like in the Appalachians. Ultimately this information is intended to support dialogue and conservation on how to effectively avoid, minimize, and offset impacts from energy development to important natural areas and the valuable services they provide.

Development of a Spatially Explicit Surface Coal Mining Predictive Model
-
The goal of this project was to create a spatially explicit 1km2 grid cell model for the Appalachian Landscape Conservation Cooperative (Figure 1) predicting where surface coal mining is likely to occur in in a projected future time period, under two different scenarios. To accomplish this goal we combined GIS spatial analysis, a Random Forests predictive model, and future mining buildout scenarios. This report provides a detailed methodology of our approach and discussion of our results.

Synthesis of climate model downscaling products for the southeastern United States
-
Downscaling translates large-scale climate information to the local scale. There are several techniques for handling this process; recently, several downscaled climate products have been produced by government and academic researchers. Ecologists, conservation scientists, and practitioners require such local guidance to evaluate adaptation and conservation strategies. However, the large number of methods involved, different downscaling approaches, resolutions, time periods, and focal variables limits the ability of these users to form meaningful conclusions and evaluate the results of adaptation strategies. To address these issues, this project will summarize the methods used for downscaling, identify the metrics most appropriate for evaluation of climate model skill and usability for the ecological and conservation communities in the southeastern US, and begin a longer-term effort to evaluate the range of downscaled climate products over this geographic region.

Evaluating Effect of Climate Change on River Flows in the Clinch River Basin
-
A new project by the U.S. Geological Survey is evaluating the potential cascading effects to river flows and quality aquatic habitat due to changes in climate within an ecologically important area of the Appalachian LCC. A greater understanding of likely flow changes within the Virginia portion of the Clinch River Basin will allow managers to better respond to alterations and degradation of physical habitat. Information and results from this study will also provide managers with methods to be applied throughout the Appalachian LCC region. (Photo by Virginia Department of Game and Inland Fisheries)
