Listing
The Endangered Species Act or ESA will only
protect
a species that is officially listed as endangered or
threatened. There are two possible ways that a
species can be listed:
• If the Fish and Wildlife Service (FWS) or
National Ocean and Atmospheric
Administration (NOAA) Fisheries take the
initiative and list the species.
• By a person or organization if they create a
petition that prompts either FWS or National
Marine Fisheries Service (NMFS) to conduct a
scientific review.

Rate of Listing
• The annual rate of listing increased
from the Ford administration to the
Carter administration. Ford had 15
listings per year, Carter had 32
listings per year, Reagan had 32 per
year, George H. W. Bush had 58 per
year, Clinton had 65 per year and it
has dropped to its lowerst rate
under George W. Bush who only
had 8 listings per year.
• The rate of listing is strongly
connected to citizen involvement.
The more people create petitions
that cause FWS or NMFS to do
research, the more they are listed.
The longer species are listed, the
more likely they are to be classified
as recovering by the FWS.

Categories
There are two categories
that are on the list,
endangered and
threatened.
• Endangered species are
closer to extinction than
threatened species.
• There is a third category
called candidate
species. This status
means that the FWS
decided that the listing
is justified but listing the
species immediately is
prevented due to other
priorities.

Status
• The conservation status of a
species is an sign of the possibility
that endangered species not living.
Many factors are taken into
account when assessing the status
of a species. Not only the number
remaining, but the overall increase
or decrease in the population over
time, their breeding success rates,
all known threats, etc.
• Internationally, 190 countries have
signed an accord agreeing to
create biodiversity action plans to
protect the endangered and
threatened species. In the U.S. this
plan is usually called a species
recovery plan.
