How long has snow leopards been endangered?

Snow leopards were first listed as Endangered by the International Union for Conservation of Nature (IUCN) in 1972. This means they have been classified as endangered for over 50 years.

However, the threats to snow leopards have been present for much longer. Their population has been declining for decades due to habitat loss, poaching, and human-wildlife conflict.

It's important to note that while the official listing as Endangered happened in 1972, the threats and the decline of the species have been ongoing for a much longer time.
