The World Conservation Union (formerly the International Union for the Conservation of Nature and Natural Resources and still referred to as "IUCN") establishes criteria for determining the conservation status of species or other taxonomic groups and maintains the Red List (www.iucnredlist.org/).

The conservation status of each North American Mammal species has been identified on this web site. Do note that the conservation status of one or more subspecies of a particular mammal may differ from the parent. Almost all of the species, save one small group of bats, have been assigned an overall conservation status and that is indicated here. The status of the subspecies may be quite different from the rest of the group.

The glossary includes the IUCN definitions of the conservation status categories. The categories currently reflected among the species on the website are: Extinct, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern and Data Deficient; none of the species included in the website are listed as Extinct in the Wild.

Use the buttons to the right to search for species or their subgroups within each category.

In standard search mode, results are returned in a standard classification scheme; when "Visual Search " is checked, thumbnail images of each matching species are returned in the same order.
