"This and direct collisions with the turbines has resulted in millions of bat deaths over the last two decades," said Rodhouse. Oregon and Washington have 3,600 wind turbines that generating capacity of 6,300 megawatts. Most wind farms are clustered near the Columbia River Gorge. Others are near Ellensburg and Walla Walla in Washington and Baker City in Oregon.
Oregon and Washington combined have 3,600 wind turbines with 6,300 megawatts of installed generating capacity. In both states, the majority of the wind farms are clustered near the Columbia River Gorge, east of The Dalles. Other farms in the region can be found near Ellensburg and Walla Walla in Washington, and Baker City in Oregon. While collisions with the propellers on wind farms cause many of the deaths, barotrauma is another problem.
The surveys, which are financed by the wind industry, indicate that wind power is a relatively minor hazard to birds. But some scientists say it is still too soon to discount the risks posed by the rush to develop Northwest wind power. They are particularly concerned with the plight of hawks, eagles and other raptors, which are large, long-lived birds at the top of the food chain.
A recent study in Klickitat County, Washington shows that active wind farms in Washington and Oregon kill more than 6,500 birds and 3,000 bats annually. Biologist Orah Zamora works for West, Inc., an ecological field study company, monitors the Windy Flats project, one of the largest wind farms in the United States. Zamora looks for dead birds and bats that have been severed by the spinning blades.
A proposed wind farm on a forested ridge in eastern Skamania County could harm bats, raptors and other wildlife, a state wildlife biologist says. ... Ritter, a wind mitigation biologist based in Pasco, said the survey data on bats was "extremely interesting and alarming."
A state wildlife biologist says the Whistling Ridge Wind Project, proposed for a timbered ridge in eastern Skamania County, could cause high wildlife mortality, especially for bats and raptors. Surveys of the 1,152-acre site, including those done for the applicant, Bingen-based SDS Lumber Co., show the area is heavily used by bats, raptors and other birds, biologist Michael Ritter said in formal comments to the state agency that will decide whether to approve the project.
While the Audubon Society supports wind power, the group understandingly is lobbying state and local governments to require regional environmental impact studies before permitting proposed wind energy projects. In addition, Audubon wants each state to do a statewide survey to identify potential wind farm sites and overlay those sites with migratory bird pathways and bird and bat habitats.
