A first step in evaluating the sustainability of Appalachian ecosystem services, and how this varies across landscapes and over time, is having access to and appreciation for existing knowledge and data. This site strives to provide such access, offering a regional view of the challenges we face in conserving these crucial resources. Our description of key benefits and risks within the Appalachian Landscape Conservation Cooperative (LCC) gives an account of potential vulnerabilities to environmental and societal stressors. We focus on resources that are of broadly shared concern, while recognizing regional differences within the highly diverse Appalachian LCC.
