Three Oaks Engineering has a team of full-time experienced biologists available to conduct bat survey work.

Our Project Manager for bat surveys, Mary Frazer, has more than a decade of experience in this field and previously worked at the NC Department of Transportation where she conducted bat surveys, acoustic analyses, and consultations with the US Fish and Wildlife Service.

She assisted with bat surveys conducted by multiple organizations and agencies, and was part of the interagency team that developed a programmatic biological assessment to address the potential effects that NCDOT projects may have on the northern long-eared bat in eastern North Carolina.
