Pongo pygmaeus
About
Orangutans are among the most intelligent animals on the planet. At Chester Zoo we have both Bornean and Sumatran orangutans. Originally, the islands were connected to each other until around 40,000 years ago, allowing each species to evolve independently. Orangutans are on of our closest living relatives on the planet, sharing 97% of our DNA.
There isn’t a huge number of differences, but Bornean orangutans spend more time on the ground than their Sumatran relatives. It’s thought that this is due to the threat of tigers in Sumatra, which keeps the apes up in the safety of the trees.

Sustainable Palm Oil
The Bornean orangutan is among the many species being pushed to the brink of extinction in South East Asia by hunting, forest clearance and the planting of oil palm plantations, which are destroying vast areas of rainforest. There is intense demand for the oil, which features in all sorts of everyday products in the UK from food to cleaning materials and cosmetics.
In 2019, Chester became the world's first ‘Sustainable Palm Oil City. Our experts worked with restaurants, cafes, hotels, fast food outlets, schools and workplaces in the city to introduce sustainable palm oil policies into their supply chain.

Threats
The threats of hunting and habitat loss due to palm oil plantations is pushing these magnificent animals to the brink of extinction.
Right now, we’re working with our partners in the field to ensure the survival of this species. Our experts are carrying out important research and providing education to local communities in order to save orangutans in Southeast Asia.
