Borneo and Sumatra
Borneo and Sumatra are the only places on Earth where tigers, rhinos, orangutans, and elephants live together. The forests are home to marvelous creatures like the proboscis monkey, sun bear, clouded leopard, and flying fox bat, and endangered animals like the Sumatran tiger, Sumatran rhino, and pygmy elephant.
There are more than 15,000 known plants here, with many more species yet to be discovered. Since 1995, more than 400 species have been identified on the islands, with more than 50 of these species completely new to science. An unknown mammal species—for now dubbed the Bornean red carnivore—was photographed by one of WWF’s camera traps in 2003.
