Although Sumatran tigers are protected by law in Indonesia with tough penalties including custodial sentences and heavy fines, there has been no significant decline in poaching with more than 75% of tiger deaths per annum being deliberate for commercial gain. In spite of increased efforts by tiger conservationists, law enforcers and anti-poaching measures there is still a substantial market in Sumatra for tiger parts and products.
The shrinking habitat and reduction in prey base has meant that tigers often encroach into populated settlements looking for food. This results in increased human-tiger conflict and retributive killings and actions against the tigers. Human-tiger conflict is on the increase.
