When was the saola decalred endangered?

The saola (Pseudoryx nghetinhensis) was declared endangered shortly after its discovery in 1992, as it was recognized as one of the world's rarest large mammals. Due to habitat loss and poaching, it has been classified as critically endangered by the IUCN (International Union for Conservation of Nature) since 1996. Conservation efforts continue to be critical for the survival of this elusive species.
