Historially the Amur Leopard's range included the Amur River Basin and the mountains of northeast China and the Korean Peninsular, but today it is only found in one small area of far eastern Russia, and (possibly) Jilin Province in China. The main cause of the Amur Leopard's demise: Being hunted for its fur and for medicinal use. Declines in its traditional prey have caused the leopard to hunt domestic animal populations, causing it to be further hunted. Because population levels are so diminished, the gene pool is severely restricted, making it especially vulnerable. An additional threat is a proposed oil pipeline which would cut directly through their last remaining habitat.
