West Nile Virus Taking Toll on Greater Sage-grouse Across the West
CHANDLER, ARIZ. - The
U.S. Geological Survey National Wildlife Health Center has reported that
West Nile virus continued to spread into previously uninfected populations
of greater sage-grouse across the West in 2006.
The disease has now been detected in sage-grouse in California,
Colorado, Idaho, Montana, Nevada, Oregon, North Dakota, South Dakota,
Utah and Wyoming, as well as Alberta, Canada. Experimental studies at
have shown that West Nile virus is usually fatal to sage-grouse, resulting
in death within 6 days of infection.
West Nile virus represents the latest factor in the decline of greater
sage-grouse populations. The species already suffers from habitat loss.
Livestock grazing, oil and
gas drilling, off-road vehicle use, the spread of invasive species, and
the placement and construction of roads, fences and utility corridors
continue to fragment and degrade what remains. 
"The evidence that supports listing greater sage-grouse under the
Endangered Species Act is mounting," said Mark Salvo, Director of
the Sagebrush Sea Campaign.
The historic range of greater sage-grouse closely conformed to the distribution
of sagebrush-steppe in what became twelve western states and three Canadian
provinces. But since 1900 sage
grouse populations have declined. Greater sage-grouse distribution has
decreased by at least 44 percent while overall abundance has been reduced
by as much as 93 percent from historic levels. 
Dr. Clait E. Braun, former Avian Research Program Manager for the Colorado
Division of Wildlife, has produced "A
Blueprint for Sage-grouse Conservation and Recovery" to manage
threats to greater sage-grouse and increase both sage-grouse populations
and range. Federal and state agencies
and sage-grouse working groups are urged to adopt the management guidelines
in the report.
The Sagebrush Sea Campaign focuses public attention and conservation resources
on protecting and restoring the vast sagebrush-steppe landscape. The campaign
participates in public planning processes, advocates for natural resource
protection, and uses education, research, legislation and litigation to
conserve and restore the Sagebrush Sea for present and future generations.
The Sagebrush Sea Campaign is a project of Forest Guardians.
