List of endangered mammals

The IUCN also lists 86 mammalian subspecies as endangered. Of the subpopulations of mammals evaluated by the IUCN, five species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction".
