The destruction and degradation of the tropical rain forest, particularly lowland forest, in Borneo and Sumatra is the main reason orangutans are threatened with extinction.
What are threats to orangutan?
Unfortunately, there are many threats to the remaining wild populations of orangutans. Deforestation for the benefit of oil palm plantations, mining, infrastructure, illegal logging, forest and peat fires, illegal hunting, and illegal wildlife trade are just a few of the threats against the wild orangutans.
How are orangutans being threatened?
Deforestation and Habitat Loss Illegal logging inside protected areas and unsustainable logging in concessions where orangutans live remains a major threat to their survival. Today, more than 50% of orangutans are found outside protected areas in forests under management by timber, palm oil and mining companies.
Why is deforestation a threat to orangutans?
The primary threat to the orangutan’s habitats is deforestation for the benefit of oil palm plantations, mining, and infrastructure. In addition, forest and peat fires degrade the forests further. Over 60 percent of orangutan habitats in Indonesia and Malaysia have been destroyed in the past four decades.
What is killing the orangutans?
More than 100,000 Critically Endangered orangutans have been killed in Borneo since 1999, research has revealed. Scientists who carried out a 16-year survey on the island described the figure as “mind-boggling”. Deforestation, driven by logging, oil palm, mining and paper mills, continues to be the main culprit.
