According to the International Union for Conservation of Nature (IUCN), the total population of all three orangutan species is estimated to be between 104,700 and 119,600 individuals. Here's a breakdown of the estimated population for each species:
Bornean Orangutan (Pongo pygmaeus):
- Total population: Approximately 54,000 to 57,000 individuals
- Found primarily in the rainforests of Borneo, including parts of Indonesia and Malaysia.
Sumatran Orangutan (Pongo abelii):
- Total population: Approximately 14,000 to 16,000 individuals
- Restricted to the northern parts of Sumatra, Indonesia.
Tapanuli Orangutan (Pongo tapanuliensis):
- Total population: Approximately 800 to 1,000 individuals
- Critically endangered and found exclusively in the Batang Toru forest in North Sumatra, Indonesia.
It's important to note that these population estimates may vary based on different research methodologies and the complexity of studying and surveying orangutan habitats. Additionally, conservation efforts and habitat preservation initiatives are crucial for ensuring the long-term survival of orangutans in the wild.
