[Animals] Sumatran Orangutan | Species

[Aronus]

Derived from the Malay words for “person of the forest," Sumatran orangutans are critically endangered.

 

 

 

The Sumatran orangutan is almost exclusively arboreal, living among the trees of tropical rainforests. Females virtually never travel on the ground and adult males do so rarely. Sumatran orangutans are reported to have closer social ties than their Bornean cousins. This has been attributed to mass fruit on fig trees, where groups of Sumatran orangutans can come together to feed.

Adult males are typically solitary while females are accompanied by offspring.

 

Historically, the Sumatran orangutan was distributed over the entire island of Sumatra and further south into Java. The species' range is now restricted to the north of the island with a majority in the provinces of North Sumatra and Aceh. Of the nine existing po[CENSORED]tions of Sumatran orangutans, only seven have prospects of long-term viability, each with an estimated 250 or more individuals. Only three po[CENSORED]tions contain more than 1,000 orangutans. Orangutans that were confiscated from the illegal trade or as pets are being reintroduced to Bukit Tigapuluh National Park. They number around 70 and are reproducing.
