Once found throughout south-east Asia, Javan rhinos have suffered a staggering decline in their numbers due to hunting and habitat loss. The lone wild population of Javan rhinos is one of the rarest of the rhino species—around 75 individuals—which can only be found on the island of Java, Indonesia.  The Ujung Kulon National Park, a World Heritage Site, is the last remaining refuge of Javan rhinos. But the area also suffers from the invading Arenga palm, leaving the rhinos with less food to eat and less habitat to roam. Besides, the small Javan rhino population is also extremely vulnerable to extinction due to natural catastrophes, disease, poaching and potential inbreeding.
