The wildlife rich island of Sumatra is experiencing a road building boom, causing some of its iconic creatures to be seen by construction workers: a photo of a Sumatran tiger crossing a highway work-site went viral this summer, for example.
This smallest of all tiger subspecies still needs its space despite its stature: up to 250 square kilometers for each one's territory. A single road cut into their forest habitat encroaches on these key areas, where less than 400 of these critically endangered animals persist.
Road building creates access to impenetrable forests that are home to all kinds of creatures, though, enabling illegal hunting and fragmenting habitats.
To discuss the impact of - and alternatives to - such infrastructure projects as the billion dollar Trans-Sumatran Highway, we reached Hariyo “Beebach” Wibisono, a research fellow at the San Diego Zoo Global & director of SINTAS Indonesia, plus Bill Laurance, a distinguished professor at James Cook University, who is also head of ALERT, the Alliance of Leading Environmental Researchers and Thinkers.
