The saola is one of the rarest and most enigmatic large mammals on Earth, discovered only in 1992 and already critically endangered from hunting and habitat loss in Vietnam and Laos.
The saola represents an extreme case of a species sliding toward extinction faster than conservation responses can be mobilized. The welfare dimension of their situation is difficult to assess given how little is known about their ecology and behavior, but the suffering of individuals caught in snares and dying slowly is well-documented. Saola captured for captive breeding suffered acute stress responses and rapid deterioration — their physiology appears adapted to very specific wild conditions that cannot be replicated. Snare removal programs operating in Annamite forests remove hundreds of thousands of traps annually, preventing deaths of not just saola but tigers, Asian elephants, and countless other species. The saola may already be functionally extinct.
