What Lies Beneath: Classification and Mapping of Cave and Karst Resources
This unique landform to the Appalachian region is the result of hydrologic impacts that “dissolve” porous bedrock such as limestone and create a terrain characterized by springs, caves, and sinkholes. A lack of detailed classification and mapping information creates a significant barrier for understanding these ecosystems contributions, from providing vital water quality to housing unique biodiversity.
Researchers from an array of organizations and institutions used intricate modeling to classify the diversity associated with factors like geology and hydrologic flow regimes from known or survived caves. Based on this assessment, they then predicted what level of biodiversity might be expected throughout cave and karst systems in the region. The products from this unique research include a series of maps, geospatial information layers, and other deliverables that provide a comprehensive overview for examining relationships between environmental factors, biodiversity, and distribution within karst areas of the Appalachians. This critical information will inform managers decisions above ground, in order to protect ‘what lies beneath’ absent of more detailed surveys. Next steps include working with research and management communities to integrate science information into an interactive map and scenario-based decision support tool.
