Researchers believe that the species is in constant danger of extinction due to poaching and loss of forests. Orangutan is the world’s largest tree-climbing mammal, and it is widely touted as Asia’s only great ape. Serge Wich, professor of primate biology at Liverpool John Moores University has led the group of researchers who conducted this study.
Previously, Orangutans were quite commonly found in South East Asia as well. But now, this species is confined solely to two islands; Borneo and Sumatra. The disappearance of forest habitat is mainly considered to be the most convincing reason which plays a crucial role in triggering the extinction of Orangutans in Sumatra.
In this new survey, Orangutans were found in unexpected areas which include high altitude mountains and areas west of the Toba Lake. Earlier, these areas were not considered while conducting the census.
The team which conducted this study do agrees that the population count of Orangutan has increased due to miscalculation which was done previously, but the species is still in the danger of extinction.
The researchers believe that the number of Orangutans in Sumatra from 2004 has declined for sure. The decline is happening at an alarming rate due to increased deforestation and various other poaching activities.
Serge Wich believes that more conservative measures should be taken to enhance the protection of Orangutans so that they will live happily in the Sumatran forests in the coming years as well. It is estimated that there are more than 54000 Orangutans in Borneo.
