Under the Endangered Species Act, species may have a variety of designations. Each State has similar laws that protect local populations of species in decline.
Endangered species are in danger of extinction.
Threatened species are those likely to become endangered within the “foreseeable future.”
Candidate Species are those that will be listed as threatened or endangered, unless successful conservation measures are taken to eliminate the need for listing.
Species of Concern are those potentially at risk and need more study. This designation does not carry any protections under the Endangered Species Act.
State-monitored Species are not considered a species of concern, but are monitored for status and distribution. They are managed as needed to prevent them from becoming endangered or threatened.
