Sumatran orangutan will commute seasonally between lowland, intermediate, and highland regions, following fruit availability. Undisturbed forests with broader altitudinal range can thus sustain larger orangutan populations; conversely, the fragmentation and extensive clearance of forest ranges breaks up this seasonal movement.
Sumatran orangutans are frugivores, or animals that feed on fruit. They are responsible for spreading seeds over their native area, and losing them means many tree species could also disappear.
However, the discovery of a previously unknown orangutan population in Malaysian Borneo is reason to hope. Threats. Human actions have reduced orangutan habitats by more than 80% over the past 20 ...

Ponginae / p ɒ n ˈ dʒ aɪ n iː /, also known as the Asian hominids, is a subfamily in the family Hominidae.Once a diverse lineage of Eurasian apes, the subfamily has only one extant genus, Pongo (orangutans), which contains three extant species; the Sumatran orangutan (Pongo abelii), the Tapanuli orangutan (Pongo tapanuliensis) and the Bornean orangutan (Pongo pygmaeus).
The number of Bornean orangutans has decreased by more than 60% in 60 years, and the population of the Sumatran orangutan has decreased by 80% in the last 75 years. [2] It is estimated that between 1999 and 2015, the population of Bornean orangutans has decreased by over 100,000. [2]
