Fringed bat COSEWIC assessment and status report: chapter 1

Assessment Summary – May 2004

Common name : Fringed bat

Scientific name : Myotis thysanodes

Status : Data Deficient

Reason for designation : This species is rarely reported in its Canadian range. There are, however, a few sites in the Okanagan Valley where they regularly can be captured during the summer. There is a lack of data about the extent of its Canadian range and the habitat that is important for foraging and roosting. We also do not know the population size or trends, nor any key demographic characteristics, such as population structure, reproduction or survival rates. It is not known if this species overwinters in Canada or migrates south for the winter; however, there are maternal colonies recorded in Canada.

Occurrence : British Columbia

Status history : Designated Special Concern in April 1988. Status re-examined in May 2004 and designated Data Deficient. Last assessment based on an update status report.
