3. Javan rhinoceros – Third rarest animal in the world
The Javan rhino is a critically endangered rhino that exists solely within a nature preserve found on the island of Java in Indonesia. No other herds exist anywhere other than at the Ujung Kulon National Park where the population appears to have been stabilized. This is likely because they are being guarded around the clock by Rhino Protection Units. Due to this security, there has not been any poaching in the Ujung Kulon nature preserve for over 20 years.
Poachers often target the Javan rhino for its horn’s resale value due to its use in Asian medicine. Another entirely unique threat facing the species is a palm plant named langkap that kills certain vegetation such as the rhinos preferred diet. Currently, the Javan rhino’s population is estimated to be around 60, with only around 18 of them being mature adults capable of breeding.
