This searchable directory includes contact information and self-identified areas of individual expertise for NatureServe, NatureServe Canada, and our Network Programs in the United States and Canada.
More than 60 NatureServe Network Programs collect and analyze data about the plants, animals, and ecological communities of the Western Hemisphere. They are the leading source of information on the precise locations and conditions of at-risk species and threatened ecosystems in their jurisdictions. NatureServe collects, curates, and distributes that information for use at regional, national, and international scales. Staff throughout the Network are experts in their fields, and include some of the most knowledgeable field biologists and conservation planners in their regions.
