Implementing further research was beyond the scope of the U.S. Forest Service's 2004 Final Environmental Impact Statement (FEIS) and 2005 Wasatch Powderbird Guides (WPG) Special Use Permit Renewal process for heli-skiing in the Tri-Canyon Area in the Wasatch Mountains, just east of Salt Lake City, Utah. However, in their Record of Decision the Wasaatch-Cache (WCNF) and Uinta National Forests expressed full support for undertaking a comprehensive study to more intensively examine helicopter-golden eagle interactions. This research project is a result of that commitment, with a goal of gathering more specific information on the potential effects of heli-skiing operations on golden eagles occupying territories or actively nesting in the Tri-Canyon Area, while evaluating the effectiveness of current mitigation and management practices identified in the FEIS. Of necessity, this 2006-2007 research project focused primarily on the helicopter aspects of heli-skiing. It was jointly funded by the U.S. Forest Service WCNF and Rocky Mountain Research Station, the U.S. Army Corps of Engineers Construction Engineering Research Laboratory, and Clemson University. Objectives included a golden eagle occupancy survey, experimental helicopter testing, and a recreational analysis.
