The most endangered big cat species is the Amur leopard. Native to the temperate forests of the Russian Far East and northeastern China, this leopard is critically endangered due to habitat loss, poaching, and prey depletion. With an estimated population of fewer than 100 individuals remaining in the wild, conservation efforts are crucial to its survival. Organizations are working to protect its habitat and maintain a stable prey population, alongside enforcing anti-poaching laws, to ensure this elusive and beautiful cat can thrive again.
