Abstract
 GIS to Estimate Archaeological Site Loss and Develop Conservation Strategies Track: Archaeology Author(s): Terry Jackson, Jack Tyler The state of Georgia has more than 40,000 officially recorded archaeological sites. Recent studies have estimated that these are probably just five percent of the undiscovered sites that may exist overall. Unfortunately, these same studies estimated that thousands of sites are lost annually due to development. Statewide planning maps were overlaid with a map of known archaeological sites to measure site loss and develop conservation strategies. Existing land use and land cover maps more directly measured site loss due to subsequent land use disturbances. Maps of future land use plans were overlaid to determine potential impacts. Map overlay of the Southeastern Ecological Framework, EPA-recommended conservation areas, revealed that 83 percent of known sites would potentially be protected. The results suggest that a similar periodic map study should be an important tool to monitor site loss and to develop mitigation and conservation strategies.
