The first comprehensive conservation status assessment focusing exclusively on the 45 species occurring in North America
north of Mexico. Although most North American bats have large range sizes and large populations, as of 2015,
18–31% of the species were at risk (categorized as having vulnerable, imperiled, or critically imperiled
NatureServe conservation statuses) and therefore among the most imperiled terrestrial vertebrates on the continent.PublicationJournal ArticleBiological Conservation
