As part of its mission to support the global deployment of wind energy through a better understanding of environmental issues, WREN has created a free, online tool to catalog monitoring and mitigating technologies developed to assess and reduce potential wildlife impacts resulting from land-based and offshore wind energy development. The tool will be continuously maintained and updated to ensure the international community has access to current, publicly available information on monitoring and mitigation solutions, their state of development, and related research on their effectiveness.
Results can be refined by selecting from the drop down menus or entering a search term. Listed monitoring and mitigation technologies are reviewed on an annual basis, but can be updated more frequently if needed, by emailing tethys@pnnl.gov. The wind energy community may also contribute additional technologies for consideration by filling out this survey.
You can also download the full list of monitoring and mitigation technologies or look up definition of terms used in this tool.

Small-Scale Field Study
Wiggelinkhuizen et al. (2006) tested the capacity of the WT-Bird system for detecting bird collisions with 50 gram bird dummies to simulate the bird species found in the coastal Netherlands. The authors also discuss the functionality of the prototype system. ...Read moreWiggelinkhuizen et al.

The authors also discuss the functionality of the prototype system. Verhoef et al. (2004) discuss the development and testing of the WT-Bird system as well as the unresolved challenges at the end of the project. The WT-Bird system was tested with tennis balls at a 500KW turbine near Rotterdam, the Netherlands in 2004. Read less |
