New Research Helps Predict Bat Presence at Wind Energy Facilities

[font size=3]ALBANY, Calif.—An interactive tool developed by researchers from the USDA Forest Service’s Pacific Southwest Research Station (PSW) will help wind energy facility operators make informed decisions on efficient ways to reduce impacts on migratory bats.

Fatalities of migratory bats at wind energy facilities have become a frequent occurrence. Bat migration patterns are poorly understood and the relationship between fatalities at wind energy facilities and migratory behavior are still being studied. Previous research has shown that adjusting the operations of turbines can reduce the number of bats killed at wind energy facilities. However, this strategy has not yet been widely implemented.

Current research found that bat activity depends on time of year and a number of environmental conditions, such as wind direction and speed, air temperature, and moon phase. This suggests that there may be ways to improve the effectiveness and efficiency of mitigation measures. PSW ecologist Ted Weller and statistician Jim Baldwin developed an interactive tool that allows users to visualize how changes in date and weather conditions affect the probability of bat presence. The tool can be found at: http://www.fs.fed.us/psw/topics/wildlife/bat/batprob.shtml

“Increasing the wind speed at which turbines begin to spin and produce energy to the grid has proven to be an effective way to reduce bat fatalities. However, bat activity levels depend on more than just wind speed,” says Weller, who led the research. “Our work demonstrates the use of a decision-making tool that could protect bats when fatality risk is highest while maximizing energy production on nights with a low chance of fatalities.”



Findings from this study appear online in the Journal of Wildlife Management. Read the full article at: http://treesearch.fs.fed.us/pubs/39603
