Idaho Research Station Helps Beleaguered
Bird
By Erin
Peabody November 13, 2006
They whistle, puff their chests and strut like peacocks. But for all
their attention-getting efforts, greater sage grouse are slowly disappearing
from the American West. Once estimated to be in the millions, the birds may now
number only about 150,000.
There's one group of researchers, though, that hasn't forgotten about
the grouse: Agricultural Research Service (ARS) scientists in Dubois, Idaho.
There, at the agency's
U.S.
Sheep Experiment Station, researchers have been tracking the bird for more
than 40 years. While their focus is sheep production, scientists at the
sprawling 50,000-acre station make certain to include the needs of wildlife in
their management plans.
The sage grouse, a favorite of bird enthusiasts and wildlife
photographers, is probably best known for its elaborate mating ritual. Every
spring, the birds engage in a lot of wing-swishing, chest-puffing and whistling
to attract potential mates.
To carry out this colorful ritual, grouse need sagebrush and a variety
of other high-altitude, mountain-loving plants for food and protection.
Situated in southeastern Idaho, in the shadow of the Centennial Mountains, the
ARS research station is home to lots of sagebrushof the right kinds and
ages.

According to Dubois research leader
Gregory
Lewis, a monoculture of thick, burly sage isn't inviting to birds. Instead,
what draws the grouseas well as deer, elk, pronghorn antelope and
mooseis rich, layered vegetation.
Lewis drafts some unlikely assistants to help create this favorable
habitat: the station's 3,000 sheep. The animals' hooves and jaws open up thick,
unruly sage brush stands so that more diminutive plants can take root. Lewis
and his team also prescribe regular burns to further rejuvenate the soil and
encourage tender, green plant growth.
According to Lewis, these primary toolssheep and firehave
helped boost the station's greater sage grouse population.
