Thirty years ago, Congress passed a bill
into law that would set a standard for environmental conservation.
Never before had any nation recognized
the plight of its fish and wildlife resources and acknowledged
the aesthetic, ecological, educational, historical, recreational
and scientific value of plants and animals that were being depleted
in numbers because of untempered growth and development. The
Endangered Species Act of 1973 is considered to be a milestone
in conservation legislation. Its purpose is not only to protect
plants and animals facing extinction, but also to provide a
means for protecting and conserving the ecosystems upon which
those species depend and provide programs for their conservation.
No single law has encompassed a broader scope for the conservation
of fish and wildlife, nor has any law generated more discussion
and controversy.
The Endangered Species Act has undergone
many changes throughout its 30-year history and has been tested
repeatedly, but it still stands as one of the most important
pieces of legislation for the protection and conservation of
imperiled fish, wildlife and plant species in this country.
After World War II, the United States
experienced tremendous growth. Industries were thriving and
the human population was expanding. By the early 1970s, the
American public began to recognize the cost at which the previous
20 years of economic and industrial growth had been accomplished.
Forests had been cleared at an unprecedented rate, the air and
water had been polluted by industrial and municipal discharges;
many species of plants and animals had disappeared forever and
others were faced with extinction.
In Tennessee, the Tennessee Valley Authority
(TVA) was completing its system of dams to tame the Tennessee
River, and the U.S. Army Corps of Engineers was completing dams
on the Mississippi and Cumberland Rivers. The dams protected
the growing population from floods and provided an inexpensive
source of electricity, paving the way for industry to grow along
these water highways.
One of the first tests faced by the Endangered
Species Act after its passage in 1973 occurred in Tennessee.
In 1976, the TVA was constructing Tellico Dam on the Little
Tennessee River. An ichthyologist (fish biologist) surveying
the river discovered a species of fish never seen before. It
was determined that this fish, the Snail Darter, lived nowhere
else than the stretch of the Little Tennessee River above and
below the site where the dam was being built. Based on this
information, the Snail Darter was listed as an endangered species
and the Little Tennessee River section in the vicinity of the
dam was designated as habitat critical to the survival of the
species. Construction of Tellico Dam was halted and debate began
about whether the benefits provided by the dam outweighed the
need to protect the Snail Darter. A Congressional exemption
from the Endangered Species Act, passed in 1979, allowed for
completion of Tellico Dam, but fortunately that decision did
not spell extinction for the Snail Darter. Several additional
populations were discovered, and listing of the species resulted
in efforts to protect those remaining populations and recover
the species.
Tennessee is blessed with an abundance
of natural resources. The states diversity of habitats,
ranging from the coastal plain lowlands of West Tennessee to
the near-alpine coniferous forest in the east, harbor numerous
species of fish, mussels, crayfish, mammals, birds, reptiles,
amphibians and plants. Many of the species are endemic to Tennessee,
that is, they are found nowhere else in the world. Among the
endangered and threatened species found only in Tennessee are
such species as the Tennessee Purple Coneflower, Ruths
Golden Aster, Spring Creek Bladderpod (a plant), Nashville Crayfish,
Bluemask Darter, Smoky Madtom (a fish), and the Cumberland Pigtoe
Mussel. There are currently 101 species in Tennessee that are
listed by the U.S. Fish and Wildlife Service as endangered or
threatened. Thirteen other species inhabiting the lands and
waters of Tennessee are candidates for listing. Only Hawaii,
California, Alabama and Florida have more threatened and endangered
species.
Over the years, the Endangered Species
Act has generated much debate and misunderstanding. Some view
its requirements as a thorn in their side, another hurdle to
overcome; others believe that its purpose is to stop economic
growth and development to save species that have no value. One
of the true purposes of the act is to require federal agencies
to consider species listed as endangered or threatened in designing
and constructing their projects and to include measures for
their protection. When implemented properly, project objectives
are met and the species are protected.
Since passage of the Endangered Species
Act in 1973, tens of thousands of federal projects and activities
have been reviewed by U.S. Fish and Wildlife Service biologists
in Tennessee under Endangered Species Act provisions. Most have
proceeded as originally proposed, a small percentage have required
further consultation that resulted in modification of the project
before proceeding, and only one has actually been stopped because
of its potential environmental effects and effects to endangered
species.
Another purpose of the Endangered Species
Act is to protect individual endangered and threatened plants
and animals from "take." "Take" is defined
as to harm, harass, injure or kill a species or destroy essential
habitat) without finding ways to minimize the threats and provide
for the long-term survival and recovery of the species.
"Take" of listed species is
prohibited and carries severe penalties, but the Endangered
Species Act provides for "take" that is incidental
to otherwise lawful activities. Federal agencies are protected
from violation of the acts "take" provisions
through consultation with the U.S. Fish and Wildlife Service,
but until recently, non-federal agencies and private landowners
would face possible prosecution for "take" of listed
species. The 1988 amendments to the Endangered Species Act authorized
the issuance of permits to private landowners and non-Federal
agencies conducting lawful activities to "take" species,
but require measures to "minimize and mitigate the take
to the maximum extent practicable." Applicants for incidental
"take" permits must prepare a habitat conservation
plan that describes the proposed action and its effects on listed
species and identifies measures to mitigate "take"
that may occur as a result of the action. U.S. Fish and Wildlife
Service biologists in Tennessee have worked with many private
individuals and organizations to protect wildlife while allowing
them to use their land.
"Tennessee has the fourth highest
number of federally endangered species in the United States,
with a number of these species being state endemics. While Tennessee
shares the responsibility for the recovery and protection of
many of these listed species with other states, we are solely
responsible for the recovery and protection of those that are
state endemics," says Reggie Reeves, director of the Division
of Natural Heritage of the Tennessee Department of Environment
and Conservation.
"In Tennessee, the Endangered Species
Act has proven to be a principal catalyst for the conservation
of these globally rare species of plants and animals,"
Reeves adds.
"Both the science behind the formal
listing process, and the significance placed on the recovery
of listed species, play a critical role in selecting areas in
Tennessee for protection under the State Natural Areas Program,"
Reeves says. Tennessee currently has 64 State Natural Areas
covering over 100,000 acres of ecologically significant lands.
Many of these natural areas were selected based on the presence
of federally listed species and high quality habitats. Long-term
conservation of such lands contributes directly to the recovery
goals of individual species. In some cases, acquisition of these
important natural areas was made possible only through funding
assistance under the Endangered Species Act. And more often
than not, identification of potential natural areas is a direct
result of rare species inventory funding under the Endangered
Species Act."
"The Endangered Species Act has
given the state of Tennessee the ability to produce on-the-ground
results contributing to the recovery of our endangered and threatened
plant species. The recent downlisting of the Large-flowered
Skullcap (Scutellaria montana) from endangered to threatened
is a prime example of the acts success," says David
Lincicome, administrator of the Rare Species Protection Program
of TDECs Division of Natural Heritage.
"Without such strong, protective
legislation and financial assistance, the recovery of Tennessees
rare plant species would be less successful. Although the level
of protection granted to rare plant species under the act is
not perfect, the administrators of its programs continue to
develop new and creative approaches advancing protection to
more rare plant populations. Consequently, the future for Tennessees
botanical treasures looks bright despite much recovery work
that remains," Lincicome says.
We have learned much through our experiences
in implementing the provisions of the Endangered Species Act.
We have learned that economic growth and endangered species
protection are not mutually exclusive, and that building partnerships
with agencies and individuals is the key to recovery. By working
together with development and industrial interests and with
individual landowners, we can accomplish tremendous things toward
protection of endangered plants and animals, and we can avoid
the "train wreck" situations faced in the early years.
We have been successful with some species
in Tennessee, reversing the trend toward extinction. But, there
is a long way to go. Many species remain near extinction in
Tennessee. However, if we can continue to work with others to
find innovative ways to conserve endangered and threatened species
through our authority under the Endangered Species Act, these
species have a chance to recover and once again thrive on the
lands and in the waters of Tennessee.
