Manual for determining bat presence at bridges

This manual was developed as part of a multi-year project funded by the North Carolina Department of Transportation. This project targeted the federally endangered gray bat (Myotis grisescens), so this manual is specific to that species. However, the general principles and tools described could be used for bridge surveys anywhere.

This work was conducted by principal investigators Joey Weber and Joy O’Keefe, with aid from Brianne Walters and Frank Tillman, all representing the Center for Bat Research, Outreach, and Conservation at Indiana State University, and Chris Nicolay, of UNC-Asheville. The NC DOT project was managed by Melissa Miller. You can find the project report and other documents here.
