Preliminary research shows wind turbines kill thousands of bats and birds in the Appalachian Mountains, which are a major migratory flyway, scientists say.....Dan Boone, a Maryland-based botanist and wildlife scientist, said laws such as the National Environmental Policy Act and the Endangered Species Act aren't enough to protect against bird and bat kills, deforestation and other damage done by wind turbines.
Tom Smith, director of the state Department of Conservation and Recreation's natural-heritage program, said detailed research is needed on the windmills' potential to kill birds and bats. "It's very hard to say there's not a significant impact [on birds] and not a need for additional studies," Smith said.
RICHMOND — Formal respondents in Highland New Wind Development’s case pending before the State Corporation Commission are adding to a long list of concerns expressed already by a variety of state agencies. Among those who have weighed in recently are the U.S. Fish and Wildlife Service, which expresses serious doubts about environmental reviews conducted thus far.
There seems to be no good way to properly site these turbines on unspoiled Appalachian mountains without causing irreparable damage. The State Corporation Commission has an opportunity to do the right thing by heeding the growing warnings about negative, cumulative effects its own experts are offering.
Nineteen big windmills are proposed for Highland County ridges. A new state report says: • The windmills could kill large numbers of birds and bats. • They could drive away some tourists. • More study is needed, including collecting animal carcasses if the windmills go up.
MONTEREY — A study conducted at Highland New Wind Development’s site on Allegheny Mountain last fall found a higher rate of nocturnal migration on Red Oak Knob and Tamarack than at sites where other such studies have been conducted.
This study focused on nocturnal migration patterns and flight behaviors during the peak periods of passerine and bat migration during fall 2005 at the proposed Highland New Wind Development in Highland Count. Virginia. The key results of our study were: (I) the mean overall fall passage rate was 385 targetsikmh; (2)mean nightly passage rates ranged from 9 to 2,762 targetshh, (3) the percentage of targets passing below 125 m agl was 11.5%; (4) the estimated turbine passage rate of nocturnal migrants passing within the airspace occupied by each proposed turbine was 3.4-24.7 migrantslturbineid during the fall study period; (5) fall migrants flying at or below maximal turbine height consisted of 88% birds and 12% bats; and (6) passage rates, flight altitudes, and visual observation rates of birds and bats did not differ between the two survey sites within the project area.
