Restoring grouse in Washington
It鈥檚 2 a.m., the middle of a cold March night in southern Oregon, and for five hours Kourtney Stonehouse 鈥08 has been tromping over rugged, muddy terrain, net at the ready. She stays on the heels of a man with a spotlight, and when his beam finds a roosting sage grouse, she pounces. By the end of the night she鈥檚 caught three birds鈥攁nd fallen a lot.
鈥淚t鈥檚 amazing what adrenaline, a lot of caffeine and positive thinking can do,鈥 Stonehouse said. 鈥淧lus, I didn鈥檛 want to be the weak link.鈥
On this night she was the only woman in a group of biologists and volunteers who over five nights captured 37 sage grouse. At about 4 a.m., they took the birds to a processing site to weigh, measure and fit them with radio collars. Then, after a little sleep, Stonehouse drove the birds 12 hours to the in eastern Washington, her research site.
A graduate student in Natural Resource Sciences at Washington State University, Stonehouse is working with the Washington Department of Fish and Wildlife (WDFW) and the federal Bureau of Land Management to study what kind of habitat , and also , need to thrive.
Both species once numbered in the tens of thousands and ranged across the shrub-steppe (grassland) environment of eastern Washington. Agriculture, primarily, has taken over their habitat so that only 1,200 sage and 900 sharp-tailed grouse remain in Washington. This has prompted the state to designate both species as 鈥渢hreatened,鈥 and since 2005, WDFW has been translocating birds from neighboring states to try to restore their populations.
Once Stonehouse arrived at Swanson Lakes with her cargo of birds, she took them, in specially designed boxes, to a lek, a breeding ground. She released them in the morning, when resident male grouse come to strut for mates.
鈥淲e鈥檝e found that if the translocated birds see resident birds strutting, they鈥檙e more apt to stick around,鈥 she explained.
Throughout the year Stonehouse tracks translocated grouse鈥攂oth sage and sharp-tailed鈥攂y the signals their radio collars emit.
鈥淚鈥檝e tracked birds on foot and snowshoe, by plane, ATV, truck and mountain bike,鈥 she said. Some days I walk 15 miles.鈥
All that bird location data she overlays on a highly detailed map she鈥檚 creating of the area鈥檚 vegetation. This shows her what kinds of habitat each grouse species selects for its home range and for nesting, which in turn suggests how wildlife agencies can best manage the land so that both sage and sharp-tailed grouse thrive.
Although Stonehouse鈥檚 intensive habitat study is providing new and critical data鈥攑reliminary findings indicate the two species may be more compatible than once thought鈥攂y itself it can鈥檛 ensure the future of the grouse in Washington.
鈥淚t鈥檚 going to require a lot of cooperation among many different agencies, both federal and state, and private landowners, too,鈥 she said. 鈥淚鈥檓 an advocate for the wildlife, but I鈥檓 learning that if you insist on no development, no one will listen to you.
鈥淭he trapping trips seem to come at the perfect times鈥攚hen I feel bogged down with data. Although they鈥檙e physically exhausting, I always come back rejuvenated, because I see how passionate the grouse biologists are about protecting the birds, and I see my work is making a difference.鈥
