Introducing the Javan rhinoceros (Rhinoceros sondaicus annamitcus)...

Only two populations are known to exist; the largest group of 50-60 animals resides in Ujong Kulon National Park in
Java, Indonesia.

For a long time local villagers and Vietnamese scientists knew there was something special about the large mammals in Cat Tien National Park, in the southern Annamites, but it was only in 1988 that the presence of the Javan
rhinoceros was confirmed by international scientists.

Current estimates of the  population in Vietnam range between 3 and 8 individuals. Although the two groups
are the same species, scientists believe the populations belong to different and  distinct sub-species so some suggest that they should not be crossbred. Very little
is known about Javan rhinos, especially those in Vietnam.
