Assessment rationale/justification
The situation for this species is generally similar to that for any species of bat that occurs in Canada. There are no data about populations sizes, populations 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) or data 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.; La situation de cette espèce est de façon générale semblable à celle de toutes les espèces de chauves-souris présentes au Canada. Il n'existe aucune donnée au sujet de la taille des populations, de leurs tendances ou de leurs habitudes de reproduction (on ne sait si la femelle a des portées annuelles; l'à¢ge de la maturité sexuelle est inconnu), et seulement des enregistrements dispersés documentent la présence et les tendances de distribution. En outre, il y a un manque d'information sur les habitudes d'utilisation de l'habitat (repos, alimentation) et un manque de données sur la migration. L'incertitude au sujet du statut taxinomique de cette espèce complique davantage les choses. On ne sait s'il s'agit d'un taxon distinct ni s'il s'agit d'une population distincte.
