List of recently extinct mammals

[1] One study found that extinction from habitat loss is the hardest to detect, as this might only fragment populations to the point of concealment from humans.

The main cause of habitat degradation worldwide is agriculture, with urban sprawl, logging, mining and some fishing practices close behind.

The physical destruction of a habitat, both directly (deforestation for land development or lumber) and indirectly (burning fossil fuels), is an example of this.

[9] Disease can also be a factor: white nose syndrome in bats, for example, is causing a substantial decline in their populations and may even lead to the extinction of some species.

[citation needed] Furthermore, 21% of Australia's mammals are threatened, and unlike in most other continents, the main cause is predation by feral species, such as cats.

A species is declared extinct in the wild after thorough surveys have inspected its historic range and failed to find evidence of a surviving individual.

[1] For example, a study found that 36% of purported mammalian extinction had been resolved, while the rest either had validity issues (insufficient evidence) or had been rediscovered.
