3. Amur Leopard

Amur Leopard (Panthera pardus orientalis)

Population ~ 80 – 100

> Description

The Amur Leopard, often recognized for its strikingly beautiful spotted coat, is one of the world’s most endangered big cats. Its coat, which varies from pale yellow in winter to russet or reddish-yellow in summer, is covered with large, widely spaced rosettes. The fur, particularly dense and long during winter months, can measure up to 3 inches on the body and serves as insulation against cold conditions. Adult males weigh between 70-105 pounds, while females are slightly smaller, averaging between 50-70 pounds.

> Habitat

Historically roaming throughout the Korean Peninsula, parts of China, and the Russian Far East, today’s Amur Leopard is primarily confined to a small area in the Russian Far East, with a few scattered populations in northeastern China.

> Diet

Being a carnivorous predator, the Amur Leopard’s diet consists primarily of roe deer, sika deer, hares, and other small mammals.

> Main Threats
  1. Poaching: Highly sought after for its gorgeous fur, many Amur Leopards fall victim to illegal hunting. Additionally, they face threats from poaching of their primary prey.
  2. Habitat Loss: Logging, land conversion for agriculture, and urban expansion have significantly reduced and fragmented the leopard’s habitat, leading to decreased prey and increased instances of inbreeding.
  3. Human-Wildlife Conflict: As their habitats shrink, encounters with local communities rise, sometimes resulting in retaliatory killings due to livestock predation.

The Amur Leopard’s plight highlights the interconnected challenges faced by many endangered species. Efforts to save this exquisite cat from extinction not only protect a unique subspecies but also have broader implications for biodiversity conservation in the region.
