AES has performed more than 40 wind-wildlife interaction studies. In one such study, over three years, AES completed wildlife surveys and site reviews for a proposed wind energy facility covering 100 square miles of agricultural land with scattered streams and woodlots in the upper Midwest. Following USFWS and state DNR guidance, AES ecologists conducted:
- eagle and raptor nest searches
- spring and fall surveys for migrating raptors, large birds and passerine birds
- bat acoustic monitoring at meteorological towers, and
- mist-netting for the federally-listed Indiana Bat and others
Observations at Bald eagle nests – and AES flight path mapping – identified specific areas of eagle activity. The placement of wind turbines on the site was revised and enhanced in layout design due to wildlife survey results which indicated strategies for micro-siting and maintaining appropriate setbacks from biological features. Wildlife studies enabled the wind energy developer to provide protection for sensitive habitats and species.
In permitting, AES worked with state and federal agencies to validate survey methods and the project’s conservation approach. AES’ work, which included planning for eagle conservation, demonstrated that the conservation approach had no negative impacts on wind energy generating capacity or construction efficiency.
