Keen's long-eared bat (Myotis keenii) COSEWIC assessment and status report: chapter 1

Assessment Summary

Assessment Summary – November 2003

Common name: Keen's long-eared Bat

Scientific name: Myotis Keenii

Status: Data Deficient

Reason for designation: The situation for this species is generally similar to that for any species of bats that occur in Canada. There are no data about population sizes, population trends, or patterns of reproduction (it is not known if females bear young annually; age at sexual maturity is unknown), and there are only scattered records documenting occurrence and patterns of distribution. Furthermore, there is a lack of information about patterns of habitat use (roosting, foraging) and about migration. Uncertainty about the taxonomic status of this species further complicates the matter. It is unknown if it is a distinct taxon. It is unknown if this is a distinct population.

Occurrence: British Columbia

Status history: Designated Special Concern in April 1988. Status re-examined in November 2003 and designated Data Deficient. Last assessment based on an update status report.
