What is International Orangutan Day?
International Orangutan Day, celebrated on August 19th every year, is a global event dedicated to raising awareness about critically endangered orangutans, the threats they face, and how we can help. In 2025, the message is louder than ever: save the orangutans, save the rainforest, save the planet.
Why does International Orangutan Day matter?
In short, International Orangutan Day matters because orangutans matter.
Known as "gardeners of the forest", orangutans disperse seeds across large areas, prune trees, open up canopy gaps, and they are an "umbrella species," meaning conservation efforts aimed at them benefit a wide range of wildlife.
By now, most people are aware of the challenges orangutans face, but this awareness day is a chance to bring these issues to the forefront of our minds again and to remind ourselves that we all have a part to play in helping protect them.
International Orangutan Day is important as it brings people together to learn, raise awareness, celebrate and take action!

Threats facing orangutans in the wild
Sadly, all three species of orangutans are listed on the IUCN Red List as critically endangered. Current estimates show fewer than 119,500 orangutans remain in the wild:
- Bornean orangutan: ~104,700
- Sumatran orangutan: ~13,846
- Tapanuli orangutan: ~800
Some of the most urgent threats include:
Habitat loss: The main driver of the rapid decline of all three orangutan species is habitat loss. Palm oil plantations are the leading cause of rainforest destruction, along with logging, mining, agriculture, and infrastructure development.
Human conflict: With their habitat fragmented and shrinking at a concerning rate, orangutans move closer to villages, where they're often killed as pests. Babies are usually captured for the illegal pet trade after the mother is killed.
Climate change: Adding to the pressure, climate change is altering forest habitats. Changing temperatures and rainfall patterns can lead to prolonged droughts, increasing the risk of forest fires or extreme flooding, which can cause soil erosion and damage to tree roots.

Recent orangutan conservation success stories
While August 19th is a day to raise awareness of the very real threats listed above, International Orangutan Day is also a day to celebrate the amazing strides made in orangutan conservation. Here's what's hit the headlines recently:
A MAJOR WILDLIFE SMUGGLING BUST THANKS TO A BABY ORANGUTAN
Authorities in Thailand uncovered a smuggling ring in early 2025, all triggered by a truck hauling a baby orangutan. The young orangutan, found in poor condition, tipped off investigators to a broader criminal network operating in the Chumphon Province. A raid following this discovery led to the seizure of over 17 trafficked animals, including endangered gibbons, tamarins, and red pandas. All animals were confiscated and relocated to rescue centres.
BOSF 2025 RESCUES, RELEASES & RESTORATIONS - SO FAR!
In April, the Borneo Orangutan Survival Foundation (BOSF) released six rehabilitated orangutans into East Kalimantan’s Kehje Sewen Forest, marking a major milestone as the animals took their first steps back into the wild. This year has also seen the rescue of three baby orangutans, including Esa and Indri, who arrived at the Samboja Lestari just last month. Meanwhile, on the habitat restoration front, BOSF and Land Life are on track to restore 270 hectares of degraded land by the end of August, building on the 90 hectares already recovered earlier this year through Assisted Natural Regeneration (ANR).
25 YEARS OF SUPPORT IN SABAH
Orangutan Appeal UK celebrated 25 years of impactful conservation work with the Sepilok Rehabilitation Centre in Sabah, Malaysia. Over the decades, the charity has contributed more than RM 14 million to fund veterinary care, infrastructure upgrades, research, and education. This milestone underscores the value of consistent international support in enabling long-term success for orangutan rescue and reintegration efforts.
How you can help orangutans in 2025
Not all hope is lost, and great strides have been made in orangutan conservation, but there’s always more we can do, whether it’s from home or out in the field!
1. CHOOSE CERTIFIED PRODUCTS - LOOK FOR THE LOGO
According to WWF, palm oil is found in around 50% of all packaged products in the UK, from food to cosmetics. While avoiding palm oil entirely can be challenging, you can still make a difference by choosing products that carry the RSPO (Roundtable on Sustainable Palm Oil) label. Look out for other sustainability labels too, like FSC (Forest Stewardship Council) when purchasing wood or paper products, and the Rainforest Alliance Certified seal on products such as chocolate, coffee and fruit.
2. SUPPORT ORANGUTAN CHARITIES
Support trusted groups by donating, following their social media, engaging and sharing their content, and fundraising all go a long way to support the cause. NGOs like:
- Orangutan Foundation International (OFI)
- Borneo Orangutan Survival Foundation (BOSF)
- Sumatran Orangutan Conservation Programme (SOCP)
3. SOURCE & SHARE INFORMATION
Take the time to learn more about orangutans and spread awareness. Why not share our infographic and keep orangutan conservation in conversation! #InternationalOrangutanDay
4. ADOPT AN ORANGUTAN
Symbolically adopting an orangutan helps fund medical care, rescue operations, and habitat restoration - these can make great gifts for the orangutan lovers in your life.
5. VOLUNTEER!
If you're looking to be more hands-on in your contribution, why not volunteer with orangutans? It’s holidaying with a difference, one that lets you support vital conservation work while experiencing the rainforest up close.
In a sanctuary setting: On the Samboja Lestari Orangutan Volunteer Project and at the Nyaru Menteng Orangutan Sanctuary, volunteers help further the BOSF mission of rehabilitating and releasing as many rescued orangutans as possible. As a volunteer, you'll create engaging enrichment, build platforms, reforest degraded areas and experience life in Indonesian Borneo, making a tangible difference to orangutan conservation efforts. In Malaysian Borneo, you can help care for rescued orangutans, along with a myriad of fascinating forest animals, on The Great Orangutan Project. Here, you'll work to improve husbandry and enclosure standards, create meaningful enrichment, prepare food and explore your stunning forest surroundings.
Out in the field: Volunteer out in the forests of Sabah on The Great Orangutan and Pygmy Elephant Project, where you'll help reforest vital habitat zones like the renowned 'Corridor of Life'. You'll take part in wildlife observation and monitoring as you trek through the jungle in search of orangutans, pygmy elephants, and other incredible species. You'll also have the unique opportunity to spend time with the 'Orang Sungai', gaining insight into their culture and how they coexist with the surrounding wildlife.
