orangutan
Female orangutans (Pongo) have the longest breeding interval of any mammal, giving birth on average once every eight years.
Oil palm plantations pose a severe threat to orangutan populations primarily by driving the destruction and fragmentation of their native rainforest habitats in Indonesia and Malaysia.123
The expansion of the palm oil industry has led to the following critical impacts:
- Habitat Loss: To establish new plantations, large swaths of tropical forest are cleared, depriving orangutans of the living space and food resources necessary for their survival.12
- Slash-and-Burn Practices: New plantations are frequently created using slash-and-burn methods. This process not only destroys the forest but also contributes to poor air quality and increases the risk of uncontrolled wildfires, which further degrade the remaining ecosystem.453
- Fragmentation: The conversion of contiguous forests into isolated patches of habitat hinders the ability of orangutans to move, forage, and reproduce. These fragmented areas are often too small to support territorial animals and increase the risk of encounters with human threats.253
As a result of these pressures, all three species of orangutans are classified as critically endangered and face the risk of extinction.1
