The post-construction bird/bat mortality survey at the expanded Buffalo Mountain windfarm found an adjusted bat mortality rate of 63.9 bats/turbine/year. This figure is similar in magnitude to the bat mortality recorded in West Virginia (47.5 bats/turbine/year). Fewer bird strikes were recorded in this same survey.
The following report describes the research design, initiation and completion of the first year of postconstruction study (fall migration only) of avian and bat collision fatalities at the 120 turbine Maple Ridge Wind Power Project in Lewis County, New York. The work was conducted in accordance with the “Proposed Scope of Work for a Postconstruction Avian and Bat Fatality Study at the Maple Ridge Wind Power Project, Lewis County, New York” dated March 14, 2006, and agreed upon in mid-May 2006, after several revisions. People/agencies who reviewed the proposed scope of work included staffers from the U. S. Fish and Wildlife Service (USFWS), U.S. Army Corps of Engineers (ACE), Environmental Design and Research (EDR), NYS DEC staffers, developers (PPM and Horizon), and others. Representatives from some or all of these groups have been included in a Technical Advisory Committee (TAC), which has the responsibility of reviewing and commenting on progress reports, annual reports, and other updates from this project.
Comments submitted to the California Energy Commission regarding proposed guidelines for conducting post-construction bird-bat mortality surveys at wind energy facilities. These comments were submitted by Dan Boone, a wildlife biologist with over 30 years professional experience.
The New York State Department of Environmental Conservation (DEC) reviewed the Draft Generic Environmental Impact Statement (DGEIS) for PPM's Horse Creek wind facility proposed for the New York towns of Clayton and Orleans, Jefferson County. The project consists of approximately 62 wind turbines (130 MW) with 54 turbines in the Town of Clayton and 8 turbines in the Town of Orleans. The project scope also includes construction of two permanent meteorological (met) towers, an operations and maintenance facility, approximately 16 miles of gravel access roads and approximately 28 miles of buried electric collection lines, and an interconnection substation adjacent to the existing electric transmission line.
This report, authored by the Wind Energy and Bats subcommittee to the Pennsylvania Biological Survey's (PaBS) Mammal Technical Committee, documents the PA Game Commission's direct side-stepping of a long-established memorandum of agreement with the PaBS when the Game Commission developed and finalized the Wind Energy Voluntary Cooperation Agreement without the review or input of the Biological Survey. The memorandum of agreement was created over 10 years ago to help ensure that the Game Commission obtained advice from experts about actions affecting the mammals inhabiting the Commonwealth.

Excerpts below are from the May 16, 2007 Proposed Order of WV PSC denying Liberty Gap's application for CPCN (siting permit) for 50 wind turbine project atop Jack Mtn in Pendleton County:
This document includes studies in Maine, Maryland, Minnesota, New Hampshire, New York, Pennsylvania, Vermont, Virginia and West Virginia.
As a general comment, the Service appreciates the fact that UPC Wind has conducted radar and acoustic studies on bird and bat migration and bat activity at Hardscrabble Mountain and other locations at or near the proposed project. We believe the radar, visual, and acoustic information contained in the above-referenced reports is useful, but that it is not sufficient to demonstrate, at an appropriate scale, the spatial and temporal uses of the airspace over Granby, Libby, Barrett, and Norris Mountains by birds, bats, and insects.
Rick Webb's presentation on October 17 at the Energy Virginia conference provides a thought provoking analysis of the costs and benefits of industrial wind energy.
To reiterate, if the SCC chooses to license this project, we request adherence to the monitoring and mitigation recommendations described in this letter and attachments. In the absence of such conditions, we feel this project would pose an unacceptable risk to the Commonwealth’s wildlife resources.
Below are two Phase I Avian Risk Assessments reports, prepared by Paul Kerlinger, for Vermont's East Haven Wind Farm (July 2003) and New Hampshire's Lempster Mountain Wind Power Project (June 2005). Phase I assessments have proven inadequate in assessing mortality at several sites in the U.S. including Mountaineer in West Virginia and Meyersdale in Pennsylvania. The US Fish and Wildlife Interim Wind/Wildlife Guidelines calls for multi-year evaluation of avian and bat activity using remote sensing.
Starting with our first interagency meeting on April 8, 2005, we have generally discussed three broad categories of activities that pose a potential concern for fish and wildlife resources. These include the potential for bird and bat collisions with turbines, habitat fragmentation effects on wildlife and impacts to waters/wetlands. At the April 8, 2005 interagency meeting, we recommended that CEI collect three (3) years of radar data on spring and fall bird/bat migrations to document the spatial and temporal use of the airspace by these flying vertebrates. Three years of radar data should be sufficient to gather information on the spatial and temporal distribution of birds in the airspace, including the year-to-year variability in migration patterns at this site, and represent our normal request for these data at wind projects. We have consistently requested that this data be collected at our meetings and field visits and continue to make this request for radar information.
ORDER IT IS HEREBY ORDERED, ADJUDGED AND DECREED by the Public Service Board of the State of Vermont that: 1. The findings, conclusions and recommendations of the Hearing Officer are hereby adopted, as modified above. 2. The proposed Project will not promote the public good of the State of Vermont, and a certificate of public good shall not be issued pursuant to 30 V.S.A. § 248. Dated at Montpelier, Vermont, this 17th day of July , 2006.
Because time seems to be running out on fossil fuels and the lure of non-polluting windpower is so seductive, some people are now promoting windpower initiatives at any cost, without investigating potential negative consequences-- and with no apparent knowledge of even recent environmental history......Throughout my experience, I could not substantiate a single claim developers made for industrial wind energy, including the one justifying its existence: that massive wind installations would meaningfully reduce our reliance on fossil fuels. When you understand this, you realize the wind business is not really that complex. But there are a lot of complicated issues swirling around it that obscure and distract from this main point, issues such as global warming, property values, the nature of wind leases, local revenues and taxes, wildlife, natural views, and a host of others. So how does one know the truth of it all? How does one go about separating the reality from spin?
Compliments of Andrew Chapman, the attached pdf files contain extensive documentation particularly with respect to the impact of wind turbines on wildlife as part of an ongoing effort to prevent the construction of the Bald Hills Wind Farm, South Gippsland, Victoria. While it has been approved by the Victorian State Government the presence in the Bald Hills area of migratory species of national and international significance that are protected by treaties with Japan and China in the Bald Hills has placed the final decision in the hands of the Federal Government. This decision is pending.
The Service favors: --conservation of wildlife in the public trust; --development of renewable energy that is bird and bat friendly; and --use of informed decisions based on adequate environmental assessment and sound science.
In its submission today, the department will not reiterate all of the matters raised in the 21 October submission, rather the department wishes to focus largely on the matters arising from this proposal affecting Brolga and Southern Bent-wing Bat.
We believe that wildlife kills can be prevented or minimized, and we advocate broad collaboration to achieve this end. However, until reliable solutions are developed, high risk areas should be avoided. These include locations along major migratory corridors or within the normal flight range of large roosting and feeding aggregations of birds or bats.
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.
