American Pika Advances Toward Endangered Species Act Protection
Small Alpine Mammal Imperiled by Global Warming
U.S. Fish and Wildlife Service today announced that it is launching a
full status review to determine whether the American pika, a small,
alpine-dwelling relative of the rabbit that is imperiled by global

Superior Court Judge Peter Busch ruled from the Bench on April 16, 2009
that the California Fish and Game Commission violated state law when it
rejected last spring a petition authored by
the Center for Biological Diversity to list pika as threatened or
endangered under the California Endangered Species Act. The ruling will
send the state pika petition back to the Commission for reconsideration.
in boulder fields near mountain peaks in the western United States.
Adapted to cold alpine conditions, pikas are intolerant of high
temperatures and can die from overheating when exposed
to temperatures as low as 78 degrees Fahrenheit for just a few hours.
Global warming threatens pikas by exposing them to heat stress,
lowering food availability in the mountain meadows where they forage,
reducing the amount of time when they can gather food,
and reducing the insulating snowpack during winter.
pollution have already led to dramatic losses of lower-elevation pika
populations. More than a third of documented pika populations in the
Great Basin mountains of Nevada and Oregon have gone
extinct in the past century as temperatures warm, and those that remain
are found an average of 900 feet further upslope. According to climate
experts, temperatures in the western United States in this century will
increase at least twice as much as they did
in the past century. This could eliminate the pika from large regions
of the American West.
elevations are being driven to extinction, pushing pikas further
upslope until they have nowhere left to go,” said Shaye Wolf, a
biologist with the Center for Biological Diversity. “Pikas
are in urgent need of the protections of the federal and state
Endangered Species Acts, which have a proven track record of success in
protecting imperiled wildlife.”
of these empirical studies, along with predictions of declining
climatic habitat suitability, we find that the range of the American
pika and the habitat within the range are likely to decrease
as surface temperatures increase. …Therefore, we find that the
petitioner presents substantial information to indicate that listing
the American pika may be warranted as a threatened or endangered
species due to the present or threatened destruction, modification,
or curtailment of its range due to impacts attributed to climate
- Pikas live in boulder fields surrounded by meadows on mountain
peaks. They avoid the summer heat by seeking the cool crevices under
the boulders and by remaining inactive during warm periods.
do not hibernate during the long, cold, snowy winters at high
elevations, but remain under boulder piles protected by their dense,
insulating coat of fur. The dense coat that protects them in winter
makes them vulnerable to heat stroke during the
- Pikas spend summers diligently gathering
flowers and grasses and store them in “haypiles” for food to sustain
them through the long winters. These “boulder bunnies,” which weigh
only a third of a pound, must collect more than 60 pounds of vegetation
survive the winter.
- Pikas are not only threatened by rising
temperatures in the summer, but also by the loss of the insulating
snowpack in the winter, which leaves them exposed to cold snaps.
