WIND TURBINES THREATEN WISCONSIN BATS

by Tony Walter,

Wind turbine industry reports filed with the Public Service Commission of Wisconsin indicate that a significant number of bats fall victim to the turbine blades every night, which could mean crop losses.

The rate of bat mortality has a major impact on the agricultural industry, according to a U.S. Geological study recently published in Science Magazine.

The study, conducted by Boston University’s biology department, estimated that insect-eating bats save the agricultural industry at least $3 billion a year.

“Because the agricultural value of bats in the Northeast is small compared with other parts of the country, such losses could be even more substantial in the extensive agricultural regions in the Midwest and the Great Plains where wind-energy development is booming and the fungus responsible for white-nose syndrome was recently detected,” said Tom Kunz, an ecology professor at Boston University and co-author of the study.

White nose syndrome is a disease believed to kill and sicken bats, which first was noticed in Albany, N.Y., in 2006, according to the U.S. Fish and Wildlife Service. The source of the condition remains unclear, the agency said.

According to studies by Current Biology, National Geographic and Science Daily, bats can be killed without being struck by a turbine blade. The studies concluded that air in low-pressure areas near the tips of the blades ruptures the bats’ lungs and causes internal hemorrhaging.

In PSC reports obtained by the Green Bay Press-Gazette, a post-construction bat mortality study of the Wisconsin Power and Light Company’s Cedar Ridge Wind Farm in Fond du Lac County, conducted by the power company, showed that 50 bats are killed annually by each of the project’s 41 turbines — about 2,050 each year.

Similarly, reports show that the 88 turbines in the Blue Sky Green Field Wind Energy Center in Fond du Lac County each kill an estimated 41 bats per year, which is a little more than 3,600 each year, according to the Wind Energy Center’s post-construction study.

Each turbine in the state kills about 41 bats each year, according to estimates compiled by the Wisconsin Department of Natural Resources.

“I can verify that bats are good natural predators of insects and definitely benefit agriculture,” said Mark Hagedorn, agricultural agent for the UW-Extension.

The largest known area for hibernating bats in Wisconsin is the Neda Mine State Natural Area in Dodge County, where a census found 143,000 bats, according to the DNR.

The construction of wind turbines in Brown County has been a controversial subject for years, but most of the complaints focused on the safety and health impact on humans. The impact on bats has not been part of the debate over wind turbine construction in Brown County.

Recently, Invenergy Inc. abandoned its plans to build a 100-turbine wind farm in four southern Brown County municipalities. The town of Glenmore last month approved permits for Cenergy to build eight turbines in the town.



BATS ON THE BRINK:

By Jennifer L.W. Fink


Three wind farms – Butler Ridge Wind Farm in the town of Herman, Cedar Ridge Wind Farm in Fond du Lac County and another near Byron – have gone up within miles of the hibernaculum, and preliminary data suggest the wind towers may be responsible for the deaths of migrating bats. “We’re seeing some of the highest fatality numbers in the U.S.,” Redell says.

A century ago, Neda was an iron town. Hardy miners worked deep beneath the earth’s surface, digging out precious iron ore with picks and shovels. Now the miners are just a memory, and the tunnels are dark and damp – but far from empty.

Each fall, the fluttering of wings breaks the still silence of the mine as thousands of bats migrate hundreds of miles to hibernate in the old mineshafts. Today, the old iron mine, located just south of Iron Ridge in Dodge County, is one of North America’s largest bat hibernacula. 

“Most people don’t realize that Wisconsin is such an important area for hibernating bats,” says Dave Redell, a bat ecologist with the Bureau of Endangered Resources. More than 140,000 bats, including little brown bats, northern long-eared bats, eastern pipistrelle bats and big brown bats, hibernate at Neda each winter.

Why Neda? “The old mine is big enough to host a large number of bats,” Redell says, “and the four miles of underground tunnels provide perfect hibernating conditions.” Hibernating bats require stable temperatures (41 degrees Fahrenheit is ideal), high humidity, good airflow and a private, undisturbed place. Any disturbances can awaken hibernating bats, causing them to prematurely deplete the fat stores they need to make it through the winter.

But while Neda has provided a safe haven for bats for many years, ecologists such as Redell are worried about the bats’ survival. Three wind farms – Butler Ridge Wind Farm in the town of Herman, Cedar Ridge Wind Farm in Fond du Lac County and another near Byron – have gone up within miles of the hibernaculum, and preliminary data suggest the wind towers may be responsible for the deaths of migrating bats. “We’re seeing some of the highest fatality numbers in the U.S.,” Redell says.

A new and deadly disease also has begun attacking hibernating bats, mainly in the northeastern United States. White-nose syndrome, a disease unprecedented in its ability to kill, was first identified in New York State in 2006 and has already killed more than 1 million bats. “Scientists are seeing anywhere from 90 to 100% mortality at affected hibernacula,” Redell says. While the fungal disease has not yet arrived in Wisconsin, experts believe it’s just a matter of time. “White-nose syndrome spread over 500 miles this year,” Redell says. “It’s now about 250 miles from Wisconsin.”

Scientists such as Redell are working feverishly to learn as much as possible about the disease and the state’s bats in the little time they have left. “We know that bat-to-bat transmission occurs, and now we’re trying to see if the environment remains infected,” Redell says.

Nestled deep within the earth, the mines at Neda are a world apart. For years, bats have wintered in their depths, undisturbed. Now experts can only hope that the bats don’t go the way of the miners before them.

Jennifer L.W. Fink grew up hearing stories about the bats at Neda but didn’t visit the mines until 2000. She currently lives in Mayville.


ADVICE FROM A PUBLIC RELATIONS FIRM:

Guide to Leadership, Effectiveness and Activities for Citizen Groups Pt 5

(by Robert J. Flavell. Flavell is vice chairman of The Saint Consulting Group and co-author of NIMBY Wars: The Politics of Land Use. This concludes the series begun last month)

Once the developer has identified natural supporters, outreach efforts will be needed to contact, recruit, and organize them. For that, you’ll need to find a citizen leader in the community, usually a natural supporter who has leadership abilities and feels strongly that the community needs the project.

It’s important that a local resident lead the citizen group to provide credibility and assure effectiveness. Clearly, the developer cannot manage the group, or its members will be branded as dupes and the group will lack credibility and influence.

An outsider won’t do to manage the group for much the same reason: lack of credibility and influence. Local residents will mistrust a stranger who suddenly appears in town just in time to accept leadership of the pro-development citizens group.

But a local resident who has longstanding community ties and legitimate personal reasons for supporting the project will be accepted at face value, and has the credibility to round up community support. The best way to find such a leader is to look among your natural supporters for a person with leadership skills who has the time and enthusiasm to do the job right.

You may well need to quietly fund the support group, but their expenses should be small—the cost of flyers and urns of coffee. Remember that a group seen as bought will also be seen as hirelings.

The group needs to appear independent of you and your company, which means that they may disagree with you on some points, or may have different ideas of what constitutes adequate mitigation. Taking their suggestions seriously and treating them with respect will win you points in the community.

Citizen Group Effectiveness and Activities

The effort to get a project approved and permitted organizes natural supporters to carry the issue, works to neutralize or marginalize opponents whose efforts can damage the chances of approval, and stresses the benefits to the community not through a public relations or marketing program but through the citizen advocates organized for the purpose.

Those advocates will express their support in their own words and from their own point of view, a much more effective approach than using a canned list of talking points.

Ardent supporters will also sway others who know and respect them—relatives, neighbors, co-workers, friends—will deter those who might have reservations about the project but don’t want to offend a neighbor or old friend, and can dissuade, neutralize or turn at least some opponents because they clearly speak from their own viewpoint and not as agents of the developer.

Make sure your group has a Web site and email address so that people tempted to support your project can easily join up.

Once it has a leader, the group can begin engaging in political support activities, forming coalitions with other groups, calling public officials to express support, writing letters to the editor, managing a website, starting a blog, printing flyers, and attending meetings and hearings, for example.

They can also hold fundraisers and seek donations to offset their expenses, and stage a site cleanup to dramatize the improvement your project will bring to the area. One particularly effective activity is the citizen petition drive, in which your group members collect signatures of local voters who favor the project, or at least are not opposed to it.

A stack of signed citizen petitions makes a nice prop for your lawyer to present to the licensing authority at the big hearing to bolster your claim of widespread public support.

 

4/1/11 How Green is a Bat Killing Turbine? Dead bats mean more corn borer larvae, more pesticides and lower crop yields AND When wind developers say MAKE ME: Invenergy ignores PSC's requests for latest bird and bat post construction mortality study AND It's April Fool's day but this is no foolin'--- Where wind developers have been prospecting in Wisconsin

NOTE FROM THE BPWI RESEARCH NERD: According to numbers in a previous bird and bat post construction mortality study paid for by Invenergy for the Forward Wind project located near the Horicon Marsh, the turbine related bat-kill numbers are staggering: it appears that well over 10,000 bats have been killed in just three years of the Forward project's operation.

The turbine related bat kill rate in Wisconsin is ten times higher than the national average and the second highest in North America. Yet nothing is being done about it. In fact, the Public Service Commission can't even get Invenergy to submit a long-past-due required mortality report.

Who ya' gonna call?

Better Plan has contacted the Sierra Club, the Nature Conservancy, the Audubon Society, Bat Conservation International and a multitude of journalists with this information but so far no one has moved to look more closely into this story.

Meanwhile, bats are being slaughtered by the thousands in Wisconsin wind projects. Horton may hear a Who but at the moment environmentalists and media aren't taking any calls from Horton.

BATS WORTH BILLIONS TO AGRICULTURE:

PEST-CONTROL SERVICES AT RISK

SOURCE: PRNEWSWIRE

April 1, 2011

BOSTON, -- Thomas Kunz, Warren Distinguished Professor in Boston University's Department of Biology, has coauthored an analysis published this week in the journal Science that shows how declines of bat populations caused by a new wildlife disease and fatalities at industrial-scale wind turbines could lead to substantial economic losses on the farm.

Natural pest-control services provided by insect-eating bats in the United States likely save the U.S. agricultural industry at least $3 billion a year, and yet insectivorous bats are among the most overlooked economically important, non-domesticated animals in North America, noted the study's authors, scientists from the University of Pretoria (South Africa), the U.S. Geological Survey (USGS), the University of Tennessee, and Boston University.

"People often ask why we should care about bats," said Paul Cryan, a USGS research scientist at the Fort Collins Science Center and one of the study's authors. "This analysis suggests that bats are saving us big bucks by gobbling up insects that eat or damage our crops. It is obviously beneficial that insectivorous bats are patrolling the skies at night above our fields and forests—these bats deserve help."

The value of the pest-control services to agriculture provided by bats in the U.S. alone range from a low of $3.7 billion to a high of $53 billion a year, the authors estimated. They also warned that noticeable economic losses to North American agriculture could well occur in the next 4 to 5 years because of the double-whammy effect of bat losses due to the emerging disease white-nose syndrome and fatalities of certain migratory bats at wind-energy facilities. In the Northeast, however, where white-nose syndrome has killed more than one million bats in the past few years, the effects could be evident sooner.

"Bats eat tremendous quantities of flying pest insects, so the loss of bats is likely to have long-term effects on agricultural and ecological systems," said Justin Boyles, a researcher with the University of Pretoria and the lead author of the study. "Consequently, not only is the conservation of bats important for the well-being of ecosystems, but it is also in the best interest of national and international economies."

A single little brown bat, which has a body no bigger than an adult human thumb, can eat 4 to 8 grams (the weight of about a grape or two) of insects each night, the authors note. Although this may not sound like much, it adds up—the loss of one million bats in the Northeast has probably resulted in between 660 and 1,320 metric tons of insects no longer being eaten each year by bats in the region.

"Additionally, because the agricultural value of bats in the Northeast is small compared with other parts of the country, such losses could be even more substantial in the extensive agricultural regions in the Midwest and the Great Plains, where wind-energy development is booming and the fungus responsible for white-nose syndrome was recently detected," said Kunz.

Although these estimates include the costs of pesticide applications that are not needed because of the pest-control services bats provide, Boyles and his colleagues said they did not account for the detrimental effects of pesticides on ecosystems or the economic benefits of bats suppressing pest insects in forests, both of which may be considerable.

The loss of bats to white-nose syndrome has largely occurred during the past 4 years, after the disease first appeared in upstate New York. Since then, the fungus thought to cause white-nose syndrome has spread southward and westward and has now been found in 15 states and in eastern Canada. Bat declines in the Northeast, the most severely affected region in the U.S. thus far, have exceeded 70 percent. Populations of at least one species, the little brown bat, have declined so precipitously that scientists expect the species to disappear from the region within the next 20 years.

The losses of bats at wind-power facilities, however, pose a different kind of problem, according to the authors. Although several species of migratory tree-dwelling bats are particularly susceptible to wind turbines, continental-scale monitoring programs are not in place and reasons for the particular susceptibility of some bat species to turbines remain a mystery, Cryan said.

By one estimate, published by Kunz and colleagues in 2007, about 33,000 to 111,000 bats will die each year by 2020 just in the mountainous region of the Mid-Atlantic Highlands from direct collisions with wind turbines as well from lung damage caused by pressure changes bats experience when flying near moving turbine blades. In addition, surprisingly large numbers of bats are dying at wind-energy facilities in other regions of North America.

"We hope that our analysis gets people thinking more about the value of bats and why their conservation is important," said Gary McCracken, a University of Tennessee professor and co-author of the analysis. "The bottom line is that the natural pest-control services provided by bats save farmers a lot of money."

The authors conclude that solutions to reduce the impacts of white-nose syndrome and fatalities from wind turbines may be possible in the coming years, but that such work is most likely to be driven by public support that will require a wider awareness of the benefits of insectivorous bats.

The article, "Economic importance of bats in agriculture," appears in the April 1 edition of Science. Authors are J.G. Boyles, P. Cryan, G. McCracken and T. Kunz.

When it comes to big wind projects, bats in Wisconsin are in need of a super-hero

Three recent reports indicate bat kill rates in Wisconsin wind projects are ten times the national average. No state except Pennsylvania has ever had such high bat kill numbers which are among the highest in North America.

[CLICK HERE Download the We Energies Post Construction Bird and Bat Mortality Final Report]

How many bats are dying in Wisconsin wind projects?

According to the We Energies report, 3,500 bats a year are being killed in the Blue Sky Green Field 88 turbines project. Each 1.5 MW turbine represents 41 bat deaths a year. According to the study, 7,000 bats have perished in the Blue Sky, Green Field wind project during the last two years.

The kill rate is the same in the Cedar Ridge project. The Invenergy Forward project may show higher bat kill numbers.

Given this, Better Plan felt the following posting on the Wind Siting Council Docket was especially worth reading.

Public comment from Brown County resident regarding concerns about lack of DNR involvement with WSC

 The following is the text of a letter I sent to Department of Natural Resources Secretary, Matthew Frank regarding DNR representation on the Wind Siting Rule Making Commission:
April 6, 2010

Dear Secretary Frank,

My wife and I reside within the boundaries of the currently proposed Ledge Wind Energy facility in southern Brown County.

You can imagine that we have a keen interest in the proceedings of the Public Service Commission Wind Siting Commission, which convened on Monday, March 29. We attended that first meeting and plan to be in attendance at the 9:00AM meeting on April 7, as well.

At the onset, I was taken aback by the lopsided fashion in which the commission is populated with wind energy developers and proponents.

As a retired high school social studies and environmental studies teacher, I find it distressing to find no Department of Natural Resources representation on this commission. The Department`s absence raises the following questions in my mind.

Ms. Marilyn Weiss, the Public Service Commission case manager for the Ledge Wind Energy Project, in communication with people in the Ledge Wind Project area has mentioned Shari Koslowsky as the DNR Energy Division contact person for wildlife issues related to wind energy projects.

Why is she not in attendance at Siting Commission meetings?

A recent DNR reviewed bird and bat study conducted at the Blue Skies Green Fields wind farm yielded higher than average mortality rates.

With that wind farm`s location on the Niagara Cuesta, a known bird and bat migration route, should this not be a significant factor of consideration in the development of standards by the Siting Commission? If wildlife species are observed to avoid areas of wind turbine concentration, should habitat loss by abandonment not be a Department concern in a continued focus of wind energy development along the Niagara Escarpment?

The proposed Ledge Wind Energy Project is extensively underlain by karst feature, and significant groundwater contamination has occurred within the project area in the past. The construction of a wind farm involves miles of buried collection cables in addition to excavation of tower foundations. Should Department staff oversee excavation and site restoration procedures?

Considering the elevation of the Niagara Cuesta makes it particularly attractive to wind energy development, should the Department not be heavily involved in the siting standards developmental process to protect ground water resources in such sensitive areas?

Thank you for your consideration in this matter. I look forward to your reply.

I affirm that these comments are true and correct to the best of my knowledge and belief.

10/13/09 The Birds, the Bats and the proposed Glacier Hills Wind "Park"

Better Plan continues with our look at the Environmental Impact Statement (EIS) for the Glacier Hills Wind Farm proposed for the Towns of Randolph and Scott in Columbia county.

Download the entire EIS by clicking here

Today we're looking at the section called ENVIRONMENTAL EFFECTS OF THE GLACIER HILLS WIND PARK which begins on page 24 with the issue of bird mortality.

We're very troubled to learn the pre-construction bird and bat studies were done by same utility that is proposing the project.

Here's what the EIS says about birds:

"The potential for avian mortality and displacement from feeding and nesting habitat is a major environmental concern. Bird collisions with turbine blades and towers have been widely reported in this country and abroad.

WEPCO conducted a pre-construction avian study of the project area between mid-June 2007 and mid-June 2008.1 The methodology used and the timing of the survey was consistent with the Breeding Bird Survey methodology and provided a general assessment of bird use in the project area during the one-year study period. The avian study did not identify any heavily used local flight paths or any locations in the project area
where bird activity was heavily concentrated.

The surveys recorded observations of 151 bird species.
Three state-listed threatened species were recorded. An additional 20 species that are listed as species of greatest conservation need (SGCN) were observed in the project area.

Almost all project construction would occur on active agricultural lands. Only a small amount of habitat other than agricultural lands would be directly disturbed by the project. Active agricultural lands provide feeding areas for some bird species during migration and winter but provide only limited habitat for nesting birds. The impact to bird habitat from direct habitat removal and from fragmentation of existing habitat would be relatively low."

NOTE: Though the impact to bird nesting habitat would be relatively low, what about the impact to the birds themselves? Concern about the effects of a large scale industrial wind farms on actual bird populations is growing.

According to a new study by the Britain's Royal Society for the Protection of Birds, wind farms can reduce bird numbers by up to half. [click here for source]The research, published in the Journal of Applied Ecology, suggests the most likely cause of the decline is the fact that birds are less likely to live near wind farms because of the noise and development.

In another report, [source]  Purdue University Associate Professor John Dunning says wind turbines  could also pose a threat to animals that share the airspace: “The worry is if you put something dramatically different, like big towers with whirling blades in it, some of the species that previously used that area, might not get killed but they might avoid going into the area,” Dunning said.

Newsweek published a recent report entitled "Birds VS Environmentalists" with the sub-heading:"The wind industry may be green, but it's proving deadly to wildlife"[source] In it, Michael Fry of the American Bird Conservancy says turbines kill three to 11 birds per megawatt of wind energy they produce. Right now, there are about 20,000 megawatts produced in the United States, which can mean—at worst—up to 220,000 bird fatalities a year. With wind energy expected to produce 20 percent of this country's energy by 2030, output would grow tenfold and, environmentalists worry, deaths could increase at a similar rate.

Because the turbines in the Glacier Hills wind farm will cover over 17,000 acres, and because out of the 151 species of birds identified in WEPCO's pre-construction study, 3 species are threatened and 20 more qualifiy as Species of Greatest Conservation Need (SGCN) we believe another independent study should be conducted by a party with no financial interest in providing results required to get approval of this project.

Residents in both the Invenergy wind farm near the Town of Byron and in the Blue Sky Green Field wind farm near the Town of Malone in Fond du Lac and Dodge counties have said there have been fewer birds since the turbines have gone up. Many have specifically mentioned the loss of barn swallows, even on farms where barn swallow flocks have been coming to nest for years.

Wind developers will often say more birds are killed by cats than by wind turbines. True or not, this statement seems intended to make turbine related bird deaths more acceptable.

Scientists study birds killed by wind turbines

By DAVID SCHECHTER / WFAA-TV

13 October 2009

 

When it comes to generating green energy from the wind, Texas leads the way.

But in the pursuit of cleaner energy, there’s also an environmental cost: dead birds and bats killed by turbine blades.

Now a unique research project in North Texas is trying to find out how many are dying and what can be done to save them.

As Texas continues to flip the switch from dirty coal to clean wind, not all is perfectly green.

That’s why Texas Christian University researchers are scanning the base of a wind turbine at Wolf Ridge, outside Muenster, Texas.

“Some of them are obvious that the turbine killed them. Other times you can’t tell,” said field technician Jennifer Ellis of the dead birds she finds.

Among them are raptors, vultures, yellow-billed cuckoos, said Amanda Hale, TCU researcher.

Birds killed by wind turbines pale in comparison to birds killed by cars, buildings and other animals.

“We do know that birds and bats are being affected by wind turbines,” said Hale.

Hale and her team want to definitively determine how many birds and bats are killed by wind turbines.

Her peer-reviewed research project is funded by the nation’s biggest renewable energy company NexTera.

“We’ve actually seen a huge variety of birds,” Hale said.

But it turns out, dead bats are the surprise finding.

Hale did not expect to find any. Instead, her team has found five times more bats than birds.

Why is that a problem?

The bat population is smaller, more susceptible to disease, and slower to reproduce.

“If we add wind on top of it, it’s enough to be a real concern,” said Hale.

Back at the Hale’s laborartory at TCU, they carry out tests.

“We can measure how good we are at finding these bats,” said Kris Karsten.

Hale’s team analyzes DNA, weather patterns and mortality trends at the Wolf Ridge Wind Farm, all for one purpose.

“If we can predict when mortality happens, we can use that information to prevent it,” said Hale.

As our reliance on wind energy grows, a discovery like that may keep us from making things worse, while we’re trying to make them better.

Bird deaths present problem at wind farms

For years, a huge wind farm in California's San Joaquin Valley was slaughtering thousands of birds, including golden eagles, red-tailed hawks and burrowing owls.

The raptors would get sliced up by the blades on the 5,400 turbines in Altamont Pass, or electrocuted by the wind farm's power lines. Scientists, wildlife agencies and turbine experts came together in an attempt to solve the problem. The result?

Protective measures put in place in an effort to reduce deaths by 50% failed. Deaths in fact soared for three of four bird species studied, said the Altamont Pass Wind Resource Area Bird Fatality Study.

The slaughter at Altamont Pass is being raised by avian scientists who say the drive among environmentalists to rapidly boost U.S. wind-farm power 20 times could lead to massive bird losses and even extinctions.

New wind projects "have the potential of killing a lot of migratory birds," said Michael Fry, director of conservation advocacy at the American Bird Conservancy in Washington.

Wind projects are being proposed for the Texas Gulf, the Atlantic Coast, the Great Plains and Upper Midwest. President Obama said in April that he would allow turbines along the Atlantic as one way to help meet a goal by environmentalists and the industry of generating 20% of the nation's electricity through wind by 2030. Currently about 1% of U.S. power comes from wind, according to the American Wind Energy Association.

"There's concern because of the scale of what we're talking about," said Shawn Smallwood, a Davis, Calif., ecologist and researcher. "Just the sheer numbers of turbines … we're going to be killing so many raptors until there are no more raptors."

Working on the problem

Interior Secretary Ken Salazar is aware of the problem and says the administration is working with energy companies and wildlife groups to help lessen the deaths.

"I think we will be able to minimize the number of birds being killed, just in terms of sheer numbers," Salazar said. "The fact that some birds will be killed is a reality."

Officials in the wind-energy industry say migratory birds and birds of prey, including eagles, are killed each year at some of the nation's biggest wind farms, but they say the concerns are overstated.

Laurie Jodziewicz, manager of siting policy for the American Wind Energy Association, said the industry has taken steps to reduce bird deaths.

"We have hundreds and hundreds of projects all over the country that are not having those impacts," she said, referring to Altamont.

Bird deaths cannot be completely eliminated, Jodziewicz said. "There will be some birds that are killed because they do collide with so many structures," Jodziewicz said.

Salazar said new technology in the design of turbines and more careful placement, such as outside of migratory paths and away from ridgelines, can reduce bird deaths.

Fry says other methods include using radar to detect and shut down turbines when migratory birds approach, building towers higher and with more space between them, and placing them away from areas where raptors hunt for small animals.

"Technology has evolved over the last several decades in significant ways," Salazar said. "We know how to do wind farms in ways that minimize and mitigate the effect on birds."

Non-wind utilities fined heavily

Some see a double standard for wind farms.

ExxonMobil pleaded guilty in federal court in August to the deaths of 85 birds at its operations in several states, according to the Department of Justice. The birds were protected by the Migratory Bird Treaty Act, and Exxon agreed to pay $600,000 in fines and fees. In July, the PacifiCorp utility of Oregon had to pay $10.5 million in fines, restitution and improvements to their equipment after 232 eagles were killed by running into power lines in Wyoming, according to the U.S. Fish and Wildlife Service.

That is far fewer than the estimated 10,000 birds (nearly all protected by the migratory bird law) that are being killed every year at Altamont, according to Robert Bryce, author of Gusher of Lies: The Dangerous Delusions of "Energy Independence." Bryce says that follows a decades-long double-standard where oil and gas companies face prosecution, but "politically popular" forms of energy get a pass.

Salazar said his department's Fish and Wildlife Service task force will recommend guidelines for wind farms that are friendlier to birds.

Bird advocates raise doubts about the impact, because the guidelines are voluntary.

"It's still entirely up to power companies where to place towers," said Gavin Shire, spokesman for the American Bird Conservancy.

 
 
 
 
 

Bats

We are grateful to the PSC for recognizing that the number of bat fatalities caused by the Glacier Hills wind turbines could be high.

Here's what the EIS has to say about bats:

Bat mortality has exceeded bird mortality at most wind farms where post-construction monitoring of both animal groups has been conducted.

Many species of bats are long-lived and have low reproductive rates.

Also, Bat Conservation International estimates that more than 50 percent of American bat species are in decline.

These characteristics make bat populations more vulnerable to the cumulative impacts that could occur as the number of wind projects continues to increase.

Seven species of bats are known to occur in Wisconsin; five of these are state species of special concern exhibiting some evidence of decline.

Very few bat studies have been conducted in Wisconsin and thus bat numbers and behavior are not well understood.

A pre-construction bat activity study was conducted in the Glacier Hills project area. The study, based on acoustic surveys, focused on bat activity patterns during the post-breeding and fall migration periods. No species identifications were performed during the study.

It is certain there will be some level of bat mortality if the proposed wind farm is constructed. However,due to the lack of research on bat mortality at wind farms in the Midwest, it is not possible to make predictions about the magnitude of bat mortality for this project or whether that mortality would have a significant impact on bat populations.

Post-construction mortality studies are being conducted at three recently completed wind projects in Wisconsin, including WEPCO’s Blue Sky Green Field (BSGF) project. These projects have land cover similar to that present within or adjacent to the Glacier Hills project boundary. In addition, the projected bat activity levels based on pre-construction surveys at BSGF are similar to the pre-construction estimates for the Glacier Hills project.

The initial post-construction data from the BSGF project show a high level of bat mortality.3 Thus, it is possible that bat mortality at Glacier Hills could also be high.

NOTE FROM THE BPWI RESEARCH NERD: Many residents of wind farms in our state have pointed out that studies have been done on the effect of wind turbines on birds and bats, but none have been done on the effect wind turbines have on the people who are forced to live with them.
