Why They Matter
Orangutans are frugivores and play a vital role in the dispersal of seeds over a huge area. If orangutans were to disappear, so would several tree species, especially those with larger seeds.
The tropical rainforests where Sumatran orangutans live are also home to other spectacular species including rare Sumatran tigers, Sumatran elephants, and Sumatran rhinoceroses.
The forests orangutans call home are a vital source for fresh water. Rivers and streams from these forests provide local communities with water for drinking, cooking, bathing, irrigation and hydroelectricity. The forests are also a valuable source for wildlife products like honey and rattan.
