Jeff Gruver

Consulting Ecologist/Senior Bat Biologist

Jeff has been involved in bat research since 1996, and has led studies on bat ecology throughout North America. Jeff’s primary focus at WEST is to assist clients in understanding and managing risk to bats that arise from otherwise lawful activities. As a result, most of his work occurs in the Midwest and eastern U.S. where species that are currently endangered and threatened occur. Jeff has worked on dozens of projects in USFWS Regions 2, 3, 4, 5 and 6, primarily using acoustic data to understand spatiotemporal patterns of species presence. Jeff is considered to be a qualified acoustic expert, and in addition to work on numerous projects assessing species presence, Jeff led a workshop on advanced species identification at the 2013 Midwest Bat Working Group and more recently Jeff chaired a panel on acoustic presence/probable absence monitoring at the 2016 Northeast Bat Working Group Meeting.

Jeff earned a Bachelor of Science in Economics in 1993 from Penn State University and an M.S. in Zoology and Physiology from the University of Wyoming in 2002. Jeff’s Master of Science research examined the assemblage of bats near a wind power facility in southern Wyoming in relation to documented bat fatalities at the facility. Jeff has authored or co-authored scientific publications on topics ranging from species conservation assessments to factors influencing bat fatality risks at wind energy installations, and works at the forefront of understanding and using bat bio-acoustics. Jeff is the current President-elect of the Northeast Bat Working Group and sits on the Steering Committee for the North American Bat Conservation Alliance.
