Javan rhino

Javan rhinos were once widespread throughout Southeast Asia, but their populations have decreased mainly due to hunting and habitat destruction. Javan rhinos are among the rarest rhino species, with only about 75 individuals remaining in the wild on the Indonesian island of Java.

The Ujung Kulon National Park, a UNESCO World Heritage Site, is the sole surviving habitat for Javan rhinos. However, the region is also under threat from the invasive Arenga palm, which provides the rhinos with much less food and less space to wander. 

Additionally, the tiny Javan rhino population is particularly vulnerable to extinction because of natural disasters, disease, poaching, and likely inbreeding.
