Over exploitation, according to researchers, is the culprit in the decline of most species.
For the first time in four decades, a Sumatran rhino was spotted in Kalimantan, in Indonesian Borneo, sparking hope for rhino conservation efforts in Indonesia and in the world.
Researchers suggest that the few scattered populations of wild rhinoceros should be consolidated and better managed. In their study, they also identified forest protection zones that could benefit the animals and they recommend breeding to create viable populations.
There have been no signs of wild Sumatran rhinoceros in Malaysia since 2007. Since fewer than 100 Sumatran rhinoceros remain in Indonesia, conservation and breeding efforts are encouraged. The tiger was saved in India by similar strong conservation efforts by government.
