A Struggle for Survival

Habitat Loss: A Vanishing Home

The primary threat to the Sumatran tiger is habitat loss, driven by rampant deforestation and land conversion. Sumatra’s tropical rainforests, the tiger’s natural home, remain threatened by illegal logging, agricultural development, and the expansion of oil palm plantations. Sumatran tiger habitat is now heavily fragmented. As their forests are degraded, Sumatran tigers are forced into closer contact with human settlements, often resulting in deadly encounters.

Poaching: A Persistent Problem

Poaching is also a significant threat to Sumatran tigers, despite legal protection. Tigers are targeted for their skins, bones, and other body parts, all of which are highly valued in traditional medicines, particularly in China and Vietnam. Organized poaching networks continue to exploit weak law enforcement, making it difficult to stop this illegal practice. Even a single tiger killed by poachers can have devastating impacts on these fragile populations.

Prey Depletion: An IndirectThreat to Tiger Conservation

One of the often overlooked but serious threats to tiger conservation is prey depletion. As apex predators, tigers rely heavily on stable populations of large prey such as deer, wild boar, and other ungulates. However, human activities such as over-hunting, expansion of agriculture, and illegal logging have severely diminished tiger prey populations in many areas. When prey populations decline, tigers are forced to travel farther in search of food, which can lead to various stresses, reduced reproductive success, and greater likelihood of livestock depredation, thereby escalating human-tiger conflicts. In these cases, tigers are often killed or captured by local villages.

Human-Tiger Conflict: A Ubiquitous Danger

As tigers lose their habitat and the scarcity of their prey, they are more likely to venture into human-dominated areas in search of prey. Great contact with villages increases the likelihood of human-tiger conflict, particularly with local communities who may see tigers as a threat to livestock and livelihoods. In many cases, these conflicts end with the killing or capture of tigers.
