Illegal Wildlife Trade

The unsustainable surge in rhino horn poaching across Africa and Asia is due to rising consumer demand. Rhino horn is prized in areas of Asia for its reputed medical properties as well as as a carved adornment that denotes social position and pride.

Habitat Loss

Invasive species, road building, and encroachment for agricultural expansion are all threatening Sumatran rhino habitat. For example, illegal settlers are converting forest land in Sumatra’s Bukit Barisan Selatan National Park to grow coffee and rice.

Lack of Protection

Existing protected areas are insufficiently protected. Communities are not properly involved or incentivized to safeguard rhinos when they leave protected areas.

Small Population Size and Isolation

We assume that breeding among wild Sumatran rhinos is minimal in most regions due to low numbers, a low likelihood of breeding pairs encountering one another, and reproductive issues among elderly females. The majority, if not all, of the remaining sub-populations are too small to be viable breeding populations for the long term.
