The TVA Regional Heritage Program uses an innovative data management system developed by The Nature Conservancy to aid in natural resources management. The system is particularly useful in early phases of environmental assessment and natural resources planning for identifying potential conflicts with sensitive features. Three crossreferenced files are used to organize the data: a map file, a manual file, and a computer file. Elements catalogued include threatened 'and endangered species, state and federal management areas, champion trees, and significant geological features. The Heritage Program is a tool that provides the framework for centralizing known locality data concerning sensitive natural resources. It is a rich potential source of information for fish and wildlife resources managers throughout the 7 state, 201 county TVA region.
