Data Coverage
Species Taxonomic Scope

Whereas NatureServe Explorer contains information on all plants, fungi, animals, and ecosystems tracked by the Network, NatureServe​​​​​​​​​​​​​​​​​​​​​ Explorer Pro provides information on the subset of the species found on NatureServe Explorer for which precise locality or predicted distribution information is available.

For some species groups, NatureServe Explorer has comprehensive information, meaning records for all recognized species in the U.S. and Canada, global conservation status ranks, and complete state and provincial distribution information. No attempt is made to include all named subspecies, varieties, hybrids, or populations, but when these records are included, they have global ranks and complete state and provincial distributions. Due to capacity limitations, taxonomy and distributional information for these groups may lag somewhat behind the latest edition of the corresponding classification source.

For other species groups, NatureServe Explorer has incomplete information; records for species and other taxonomic levels are included to support the work of partners or because they have legal status.

NatureServe Explorer has comprehensive information for all species, subspecies, varieties, and populations with legal status regardless of whether they are part of a taxonomic group with comprehensive or incomplete information.

Searches for plants, fungi, and animals include by default only species. Subspecies, varieties, and populations for which NatureServe maintains information can be included in results by turning on the toggle to include subspecies, varieties, and populations on the Classification search tab
