(BOISE, Idaho) – Secretary of the Interior Dirk Kempthorne today
announced
the U.S. Fish and Wildlife Service is proposing to list the polar
bear as a
threatened species under the Endangered Species Act and initiating a
comprehensive scientific review to assess the current status and
future of
the species.
The Service will use the next 12 months to gather more information,
undertake additional analyses, and assess the reliability of
relevant
scientific models before making a final decision whether to list the
species.
“Polar bears are one of nature’s ultimate survivors, able to
live and
thrive in one of the world’s harshest environments,” Kempthorne
said. “But
we are concerned the polar bears’ habitat may literally be
melting.”
“Based on current analysis, there are concerns about the effect of
receding
sea ice on polar bear populations,” he said. “I am directing the
U.S. Fish
and Wildlife Service and the U.S. Geological Survey to aggressively
work
with the public and the scientific community over the next year to
broaden
our understanding of what is happening with the species. This
information
will be vital to the ultimate decision on whether the species should
be
listed.”
Polar bears are already protected under the Marine Mammal Protection
Act of
1972. Under that law, it is generally prohibited to (1) take or (2)
import
marine mammals and their parts or products.
The species is also protected by international treaties involving
countries
in the bear’s range. In early December, Congress passed the United
States-Russia Polar Bear Conservation and Management Act of 2006,
implementing a treaty with Russia designed to conserve polar bears
shared
between the two countries. President Bush is expected to sign this
legislation into law.
Today’s proposal cites the threat to polar bear populations caused
by
receding sea ice, which bears use as a platform to hunt for prey. In
recommending a proposed listing, the Fish and Wildlife Service used
scientific models that predict the impact of the loss of ice on bear
populations over the next few decades.
Scientific observations have revealed a decline in late summer
Arctic sea
ice to the extent of 7.7 percent per decade and in the perennial sea
ice
area of 9.8 percent per decade since 1978. Observations have
likewise
shown a thinning of the Arctic sea ice of 32 percent from the 1960s
and
1970s to the 1990s in some local areas.
There are 19 polar bear populations in the circumpolar Arctic,
containing
an estimated total of 20,000-25,000 bears.
The western Hudson Bay population of polar bears in Canada has
suffered a
22 percent decline. Alaska populations have not experienced a
statistically
significant decline, but Fish and Wildlife Service biologists are
concerned
that they may face such a decline in the future.
Recent scientific studies of adult polar bears in Canada and in
Alaska’s
Southern Beaufort Sea have shown weight loss and reduced cub
survival.
While data are lacking about many populations, the Service suspects
that
polar bears elsewhere are being similarly affected by the reduction
of sea
ice.
“We have sufficient scientific evidence of a threat to the species
to
warrant proposing it for listing, but we still have a lot of work to
do to
enhance our scientific models and analyses before making a final
decision,”
said U.S. Fish and Wildlife Service Director Dale Hall.
The Service extensively analyzed the impact of both onshore and
offshore
oil and gas development on polar bears and determined they do not
pose a
threat to the species.
The Service likewise examined the impact of subsistence harvest of
polar
bears by Alaska Natives. Such harvest is specifically allowed under
the
Marine Mammal Protection Act and would also be allowed if the polar
bear is
listed under the Endangered Species Act, unless the Service finds
that the
harvest is materially and negatively affecting the polar bear.
Harvesting polar bears is of great social, cultural and economic
importance
to Native peoples throughout much of the Arctic and maintaining a
harvest
within sustainable limits is one of the department’s priorities,
Kempthorne
noted.
While the proposal to list the species as threatened cites the
threat of
receding sea ice, it does not include a scientific analysis of the
causes
of climate change. That analysis is beyond the scope of the
Endangered
Species Act review process, which focuses on information about the
polar
bear and its habitat conditions, including reduced sea ice.
However, climate change science and issues of causation are
discussed in
other analyses undertaken by the Bush Administration. The
administration
treats climate change very seriously and recognizes the role of
greenhouse
gases in climate change.
The Service invites the public to submit data, information, and
comments on
the proposed rule. Comments will be accepted on the proposed
rule for the
next 90 days.
A copy of the proposed rule and other information about the proposal
is
available on the Service’s Marine Mammal website located at:

.
“Our goal ultimately is to combine the best science available with
the
power of working hand-in-hand with states, tribes, foreign
countries,
industry, and other partners to minimize the threats to polar bears
and
conserve this great icon of the Arctic for future generations,”
Kempthorne
said.
