A few of Indonesia’s 17,000 islands tend to take the conservation spotlight. The forests of Kalimantan and Sumatra, for example, are well known thanks to iconic residents like orangutans and tigers. Meanwhile, Papua, in the country’s east, boasts dozens of unique bird species.

But Indonesia has thousands of other islands—known collectively as the Wallacea Biodiversity Hotspot—that are also a conservation priority. Threats including logging and hunting are placing Wallacea’s vulnerable ecosystems, and the species that depend on them, in jeopardy.
