NatureServe also maintains data on selected fungi, lichens, and algae. Although technically not plants, these groups have been traditionally included in botany departments. According to recent information from the Integrated Taxonomic Information System (ITIS), there are 18,951 native vascular plant species in the US, which include 17,848 angiosperms (flowering plants), 131 gymosperms (cone-bearing plants and related species), and 972 ferns and related species. NatureServe Explorer provides detailed information on more than 65,000 plants, animals, and ecosystems of the United States and Canada from our central databases. Our NatureServe network member programs collect and manage information on the location and conservation status of the plants in their jurisdictions.
