An excerpt from the article 22 facts about Amur leopard
The main reason behind their small numbers is excessive poaching and loss of their habitat. Fortunately, their numbers slowly, but systematically, grow, in large part thanks to the Land of the Leopard National Park in Primorsky Krai at the Russian-Chinese border. Its main goal is the protection of the species. When it was established in 2012, there were between 30 and 60 individuals of the Amur leopard in the wild. Nowadays, there are approximately 100 wild Amur leopards alive, and an additional 200 in reserves and zoos.
