Threatened, Endangered, Candidate and
In 1973, the United States
Congress passed the
Endangered Species Act (ESA). The Act entrusts the Service with the
responsibility to protect and restore federally listed threatened and endangered
species and their habitats. Similarly, the
National Marine Fisheries Service is responsible for marine species.
When a species becomes threatened or endangered, it serves as a serious health
warning for the entire ecosystem. Listed species are designated as either
endangered -- likely to become extinct throughout all or most of its range, or
threatened -- likely to become endangered in the near future. Both
designations receive the same level of protection.
Candidate and proposed species
are currently being studied to assess the need to list them under the ESA as
threatened or endangered. Candidate and proposed species are not federally
protected under the ESA; however, potential impacts to these species should be
considered. Avoiding impacts to these species now may prevent them from
being listed as either threatened or endangered in the future.
There are 10
federally listed species, one proposed species, and six candidate
species occurring within the ARLES area of responsibility.
Activities relating to the ESA in north Texas include implementing
recovery efforts for listed species; reviewing projects that could
adversely affect listed species; monitoring populations of listed
and declining species; working with partners to conserve listed
species' habitats; and educating the public about threatened and
endangered species, why they are important, and what people can do
