A coalition of six conservation groups, including Western Watersheds Project and
the Committee for the High Desert, has petitioned the U.S. Fish and Wildlife
Service to list pygmy rabbits in the Intermountain and Great Basin regions of
the West as threatened or endangered under the Endangered Species
Act.
The groups also want FWS to designate critical habitat for the rare
rabbits concurrent with ESA listing.
Scientific studies show that these
diminutive, sagebrush-dependent mammals face extinction without ESA protection.
Pygmy rabbits have been on the Red List of the International Union of Concerned
Naturalists since 1996.
The petition applies to all remaining pygmy-rabbit
populations outside the remnant Washington State population.
"The pygmy rabbit is a unique species that has
already been lost from more than 90 percent of its historic range," said Katie
Fite, conservation director of the Committee for the High Desert. "Livestock
continue to destroy the structure of sagebrush plants that are essential to the
rabbits' survival."
Pygmy rabbits depend on sagebrush for 99 percent of
their winter diet. Sagebrush also provides them with critical cover from
predators.
These small, endemic rabbits have long since won the
hearts of wildlife enthusiasts, range ecologists and even many livestock
operators.
"These entrancing little bright-eyed creatures are
animated bundles of fur . . . there is no wild creature more deserving of the
word 'cute' than these dwarves of the rabbit tribe," note E.R. Jackman and R.A.
Long in their book, "The Oregon Desert."
The geographic range of pygmy
rabbits once spanned more than 100 million acres across eight western states
(Montana, Idaho, Wyoming, Utah, Nevada, California, Oregon and Washington). That
range has declined to fragmented portions of 7 million to 8 million
acres.
Only three large populations of pygmy rabbits remain, and even
these are divided by habitat fragmentation and human impacts. Pygmy rabbits do
not disperse well and are reluctant to cross open areas, multiplying the effects
of fragmentation.
Fragmentation and loss of large sagebrush habitat are
rampant throughout the rabbits' range. Livestock grazing, which occurs on nearly
all of the areas inhabited by pygmy rabbits, radically alters sagebrush
habitat, removing forage, lowering the nutritional value of grasses, spreading
exotic weeds and diseases, collapsing burrows and attracting
predators.
Other dire threats to pygmy rabbits include prescribed fires;
manipulation of vegetation for livestock forage; oil, gas and coalbed methane
exploration and production; geothermal exploration and production; and
road-building and OHV use.
"We are concerned that this animal's
specialized sagebrush habitat needs and unique behavior make it particularly
vulnerable to the impacts of unchecked energy development like that taking place
right now on BLM lands in Wyoming," said Jeff Kessler, conservation director of
the Biodiversity Conservation Alliance there. "The BLM has repeatedly failed to
adopt needed conservation measures while the pygmy rabbit marches toward
extinction. ESA protection is therefore absolutely necessary."
"The BLM is allowing its essential sagebrush
habitats to be pounded to oblivion by livestock," said Fite. "If we can't save
this species, there is absolutely no hope for long-term survival of any
sagebrush-dependent wildlife."
Joining CHD and WWP in the petition are the American
Lands Alliance, Oregon Natural Desert Association, Center for Native Ecosystems
and Biodiversity Conservation Alliance.
