When was the Amur Leopard placed on the endangered species list?

When was the Amur leopard first placed on the endangered species list?

• I'm doing a report about them and i can't seem to find the correct answer anywhere!

• Answer:

  Under the Endanged Species Act, only species found within the United States' land or maritime borders can qualify to be listed. The Amur leopard is an endangered cat in the sense that there are very few left but it is not endangered according to the ESA and does not qualify for formal legal protections. In an international, non legal-formal sense, the non-governmental organization, IUCN Red List, listed the Amur leopard as critically endangered in 2004. The list, however, holds no legal requirements but can only serve as a recommendation to sovereign nations.
