How endangered species might be added to the list
Ever wondered how a species lands on the Endangered Species List, which is under the control of the U.S. Fish and Wildlife Service? The steps to listing or not listing species is provided in this example of what is being considered for the prairie gray fox and plains spotted skunk.
The Wildlife Service has announced, following an initial review of a petition seeking to protect the two species under the Endangered Species Act, that the two subspecies found in grasslands of some Midwestern and Great Plains states, may warrant federal protection as a threatened or endangered species.
The service will undertake a more thorough status review of the species to determine whether to propose adding the species to the federal lists of endangered and threatened wildlife and plants. The service found that information in the petition to list the Mearn’s eastern cottontail was not substantial.
Today’s announcement, known as a 90-day finding, is based on scientific information about the species provided in the petition. The 90-day finding does not mean that the Service has decided it is appropriate to give the prairie gray fox and plains spotted skunk federal protection under the ESA. Rather, this finding triggers a more thorough status review of all the biological information available.
- Based on the status review, the service will make one of three possible determinations:
Protection under the ESA is not warranted, in which case no further action will be taken.
- Protection under the ESA as threatened or endangered is warranted. In this case, the service will publish a proposal to list, solicit independent scientific peer review of the proposal, seek input from the public, and consider the input before a final decision about listing the species is made. In general, there is a one-year period between the time a species is proposed and the final decision.
- Protection under the ESA is warranted but precluded by other, higher priority activities. This means the species is added to the federal list of candidate species, and the proposal to list is deferred while the service works on listing proposals for other species that are at greater risk. A warranted but precluded finding requires subsequent annual reviews of the finding until such time as either a listing proposal is published, or a not warranted finding is made based on new information.
The Endangered Species Act makes it illegal to kill, harm or otherwise "take" a listed species, or to possess, import, export or engage in interstate or international commerce of a listed species without authorization in the form of a permit from the service. The act also requires all federal agencies to minimize the impact of their activities on listed species, and directs the service to work with federal agencies and other partners to develop and carry out recovery efforts for those species. Listing also focuses attention on the needs of the species, encouraging conservation efforts by other agencies (federal, state and local), conservation groups and other organizations and individuals.
