Wind farm would kill few birds, lawyer says - But state official says effects on birds, bats need to be studied

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.

A Radar and Visual Study of Nocturnal Bird and Bat Migration at the Proposed Highland New Wind Development Project, Virginia, Fall 2005

Radar_study_thumb 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.

Wind industry a powerful foe in energy debate

What are we in Highland to make of these statements and actions? Clearly, these men have a stake in seeing turbines on Highland’s ridges. Rather than responsibly considering the bird and bat impacts in any sort of serious way, they go to great lengths to stifle or belittle credible research recommending that wind turbines be put on hold until bat mortality can be understood and mitigated and until bird impacts can be studied.
