Javan rhinos: is the Indonesian government lying? misleading? or being straight with the world.

It appears that the counters of the Javan rhino, have continued to count animals which have not been seen for years. Given how much poaching has been going on, this seems much more than simply misleading.

 Unfortunately, this counting issue, takes the Javan rhino from a species which is recovering at an impressive rate, to a species which might disappear within a decade. In the latest count 3 rhino were included, which are known to have died back in 2019.

According to the official numbers, in 2011, when the cameras were installed there were 35 rhino, and that number has climbed steadily to a current number of roughly 72.

Sumatran Rhinoceros

Sumatran rhino is also known as a  hairy rhinoceros or Asian two-horned rhinoceros. Like the Javan rhino, the Sumatran rhino once had a range which covered a far larger area: rainforests, swamps and cloud forests in India, Bhutan, Bangladesh, Myanmar, Laos, Thailand, Malaysia, Indonesia and southwestern China, particularly in Sichuan.

There are still 3 on the island of Borneo, as you can see, the map still lists a population on the Malay peninsula though it is thought that this group is extinct. The 3 subspecies are:

  • The Sumatran island population: Western (34-47 individuals). This is unfortunately split in to 4 populations
  • The Borneo island population: Eastern (may be as low as 3). This was only discovered in 2016 in            East Kalimantan, after the population in Sabah, Malaysia (northern part of the island) was declared extinct in 2015
  • The mainland population: Northern (this is thought to be extinct as of 2010, but it is possible that a small group remain).
The Sumatran rhino spends most of its life alone, except for courtship and raising of young. It is more vocal than other rhino species, as well as communicating through marking soil with its feet, twisthing saplings into patterns, and leaving excrement. the species is much better studied than the similarly hard to see or find, for the Javan rhinoceros, in part because of a program which bought 40 Sumatran rhino into captivity in an attempt to preserve the species. Though a number of rhinos died once at the various destinations, and no offspring were produced for 20 years.

Only four areas are known to contain Sumatran rhinoceros: Bukit Barisan Selatan National park, Gunung Leuser national park, and Way Kambas National park on Sumatra, and on Borneo west of Samarindah.

We hope to be able to list trekking for seeing animals like this in the future, do get in touch if you work in this field.
