	">Can we beat the scavengers?>The Challenge of quantifying wildlife impacts of wind generation."

Dr. Rolf Koford, Iowa State University, 
Thursday, September 8 Michigan State University, in 338 Natural Resources Building

>>>Promoters of wind energy like to point to its low environmental
>>>cost.  Although mountain-top removal is not required to harvest wind
>>>energy, wind farms can negatively affect wildlife species in a variety of
>>>ways.  Mortality is the most obvious effect, but there may be behavioral
>>>effects (e.g., avoidance of areas near towers) as well.  Wildlife
>>>researchers can play a useful role by providing information used in
>>>developing siting guidelines for windfarms, by monitoring wildlife
>>>populations before and after construction, and by assessing effects on
>>>population viability.  Quantifying effects on wildlife, and understanding
>>>how they vary spatially, has proven to be challenging.  Planned
>>>experiments, the strongest basis for inference, are unheard of in 
>>>windfarm studies.  Scavengers may find carcasses before searchers 
>>>do.  Bored or >>>distracted searchers may miss some carcasses.  Behavior is variable and
>>>has  multiple influences.  In 2003-2004, a study in northern Iowa was
>>>designed to address some of these challenges at a newly constructed
>>>89-tower wind farm.  The study, funded mostly by the U.S. Fish and Wildlife
>>>Service (State Wildlife Grant), the company that managed the wind farm, and
>>>the Iowa Department of Natural Resources (IDNR), was conducted by
>>>biologists with the IDNR and Iowa State University (Iowa Cooperative Fish
>>>and Wildlife Research Unit).  The wind towers were all on gently rolling
>>>cropland (corn and soybeans).  To facilitate carcass searches, strips of
>>>ground were kept bare of vegetation.  We estimated the total number of
>>>birds and bats killed each year by adjusting the carcass counts to account
>>>for proportion of the area searched, search efficiency, and scavenging
>>>rate.  Bird abundance and bat activity (assessed with bat detectors) near
>>>towers was compared to abundance and activity away from towers.  We
>>>examined Canada Goose foraging activity and vigilance behavior in an area
>>>closed to goose hunting.  Approximately 1 million goose-use days were
>>>documented each year in three wildlife management areas within a few miles
>>>of the wind farm.  Our findings indicate which taxa were most at risk at
>>>this site.  In conjunction with results from other studies, our findings
>>>provide some guidance for siting midwestern windfarms and direct attention
>>>to additional research needs.


		>>Dr. Koford has experience researching the effects of wind towers on 
		>>wildlife.  He is a wildlife biologist working for the USGS Iowa 
		>>Cooperative Fish and Wildlife Research Unit, and has a faculty position 
		>>in the Department of Natural Resource Ecology and Management at Iowa 
		>>State University.  For the past three decades, he has conducted field 
		>>studies on a variety of vertebrate species, as well as constructing 
		>>simulation models of mallard populations.  He has conducted field work in 
		>>Arizona, California, Costa Rica, Iowa, and North Dakota.  He recently 
		>>supervised a graduate-student project on a northern Iowa wind farm that 
		>>was placed in the middle of three wildlife areas.  He helped design the 
		>>study, conduct analyses, and interpret results, thus gaining familiarity 
		>>with issues relevant to wind farms and wildlife.  The project included 
		>>assessing mortality of birds and bats, surveying abundance, and examining 
		>>behavioral responses by birds.  He has given technical assistance to 
		>>private companies and public agencies in Wisconsin in connection with the 
		>>permitting process for a proposed wind farm near Horicon Marsh.
