Effective conservation depends on useful data. At the most basic level, NDNH data answer the questions, "What is it?," "Where is it?," and "How rare is it?." At NDNH we use data methods and standards developed by NatureServe. These methods and standards, initially created in the 1970s, are continuously refined and updated to keep up with changing knowledge and technology. They also provide a common language within the NatureServe Network and a range-wide standardized dataset that crosses political boundaries. NDNH uses Biotics 5, a web-enabled biodiversity information management system to manage data about the state's rare plants, animals, and ecosystems.
