This list contains the placental mammals in the order Chiroptera. There are an estimated 1,300 species of bat.List of vulnerable mammals
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 529 vulnerable mammalian species. 9.6% of all evaluated mammalian species are listed as vulnerable.
The IUCN also lists 53 mammalian subspecies as vulnerable.
Of the subpopulations of mammals evaluated by the IUCN, five species subpopulations and one subspecies subpopulation have been assessed as vulnerable.
For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered mammals, List of critically endangered mammals. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.
Additionally 783 mammalian species (14% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."This is a complete list of vulnerable mammalian species and subspecies evaluated by the IUCN. Species and subspecies which have vulnerable subpopulations (or stocks) are indicated. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.Nyctalus
