In the latter site, Spotted Bats were the only bat species captured and appeared to be abundant; by contrast there was no evidence of this species in 6 other surveyed sites in the area. [...] The reasons for designation from the May 2004 COSEWIC assessment included the statement "It is considered the easiest and best censused species of bat in Canada", which is now known to be incorrect.

[...] Movements of individuals between British Columbia and Washington have not been documented, but there is a string of records extending northward through the Washington side of the Okanogan Valley to the BC border (Figure 2). [...] Expansion of human population and land conversions continue to occur in this area of BC, but lack of monitoring of Spotted Bat populations, distributions, or habitats precludes understanding of impacts of such changes.
