NatureServe Network's Benchmark Data Content Standards

http://www.natureserve.org/prodServices/heritagemethodology.jsp

The defining characteristic of the NatureServe network is the use of natural heritage methodology. By specifying standard procedures for gathering, organizing, and managing information on biodiversity, natural heritage methodology unites the efforts of hundreds of individuals and dozens of institutions on two continents working to advance the knowledge needed to effectively conserve biodiversity. Over the past quarter-century, natural heritage methodology has evolved to keep pace with the growth in scientific knowledge about the natural world and advances in information technologies. Nevertheless, the underlying continuity of the methodology over time has permitted the network to accumulate knowledge and make available vast amounts of scientifically authoritative data. Natural heritage methodology provides a rigorous set of procedures for identifying, inventorying, and mapping species and ecosystems of conservation concern; for gathering related information on conservation sites and managed areas; and for setting conservation priorities.
