Key Findings & Management Recommendations
-
The Appalachian LCC-funded study is the first region-wide assessment to document “flow-ecology” relationships – showing connections between observed impacts under current water withdrawal standards (based on daily water gauge data collected over the last 15 years and fish surveys) and the decline in freshwater fish communities.

Stream Impacts from Water Withdrawals in the Marcellus Shale Region
-
Conservation Challenge
-
Water withdrawals from human activities can alter surface water resources and impact aquatic habitats and organisms. The most commonly studied sources of flow alterations are typically dams and water withdrawals associated with agricultural operations and industrial uses. However, the emergence of hydraulic fracturing has led to the rapid expansion of natural gas drilling and has made it a key source in altering surface water resources in the Marcellus Shale region.

Goals for Stakeholder Engagement in Focal Landscape
-
The Appalachian LCC is engaging in an integrated, multi-scale conservation planning and design initiative throughout its geography. Phase I of this research identified five different conservation design elements. The largest element is made up of regionally connected cores. These cores are broad areas of regional significance (i.e., irreplaceability) that have high internal landscape connectivity. The LCC has strategically decided to target two of these core areas as part of its ongoing effort in Phase II of this process to reach out and collaborate with local partners working in these cores. These two areas include the Tennessee River Basin and western Pennsylvania.
