The tri-colored bat (Perimyotis subflavus) is an uncommon species that occurs in BCR 14. It hibernates in caves or mines and has been severely impacted by the white-nose syndrome (WNS). It is listed as a Species of Greatest Conservation Need in one or more states in BCR 14. It uses a variety of forest types for summer roosting and maternity areas. This species was formerly known as the Eastern pipistrelle.
If your project is in BCR 14, you are in a state where these bats occur. Contact your state wildlife agency before implementing a project. Individual state regulations may apply.
The tri-colored bat uses forested habitat for summer roosting and maternity sites. Specifics on particular preferred forest types and stand conditions are poorly understood at present. In general, summer roosting and maternity areas occur in a number of different forest types. The stand characteristics consist of a relatively closed canopy and larger stand diameters, although pole-sized trees have been used. Shaggy bark and standing dead trees with loose bark are important.
Maintain the characteristics for summer roosts and maternity areas across all the forest types in BCR 14 where this bat occurs. Avoid known roost trees or maternity trees during forest management activities. Forest management operations should not occur from May to the end of July in areas that are suspected to contain active roosting or maternity conditions.
Refer to the recommendations for the forest type you are working in.
