More than a thousand tigers prowled the Indonesian island of Sumatra when the animals were surveyed in 1978.
Today, fewer than half that number survive here and those cats are under siege by poachers and ceaseless deforestation of their home forests fueled by the pulp, paper, and palm oil industries.
A 2004 report from TRAFFIC, the IUCN/WWF effort to track the illegal wildlife trade, suggested that poachers were killing at least 40 of the critically endangered animals every year.
The Sumatran tiger (Panthera tigris sumatrae) is the last of the “island tiger” subspecies.
The neighboring Indonesian islands of Java and Bali were once home to their own distinct tigers, but the Bali tiger (Panthera tigris balica) and the Javan tiger (Panthera tigris sondaica) each died out during the 20th century.
Conservationists are working hard to help their Sumatran relatives avoid the same fate.
