Willie Smits (born February 22, 1957, in Weurt, Gelderland, the Netherlands) is a trained forester, a microbiologist, conservationist, animal rights activist, wilderness engineer and social entrepreneur. He has lived in Borneo since 1985 and is an Indonesian citizen.
While working as a forest researcher in East Kalimantan, Indonesia in 1989, Smits encountered a baby orangutan in a cage in a market, and later returned to find it abandoned on a rubbish heap. This was a turning-point in his career: taking the orangutan home, he nurtured it back to health. He was soon given other orangutans to look after, and the work of rescuing, rehabilitating and releasing orangutans into the wild developed into what was to become the Borneo Orangutan Survival Foundation. For over twenty years Smits has worked for the survival of this threatened species of ape, during which time his work has also broadened out into the related areas of sustainable farming, reforestation and remote monitoring of forests. He travels widely, raising awareness of the issues surrounding deforestation in Borneo and the plight of the orangutan, also showing how it has been possible on a relatively small scale to reverse the great damage that is being done to the orangutan and its environment. He became a senior advisor to the Ministry of Forests in Indonesia and has been knighted in the Netherlands.
In 1994, Willie Smits received his doctorate in tropical forestry and soil science at the Wageningen University in The Netherlands, based upon his research in Balikpapan, East Kalimantan, Indonesia on the symbiosis between mycorrhizas and the roots of Dipterocarpaceae tropical rainforest trees.
Wanariset Research Station
From 1985 Smits worked on the Wanariset Tropical Forest Research Station near Balikpapan in the Indonesian province of East Kalimantan. In the early 1990s he was team leader of the Tropenbos Kalimantan Project Indonesia, an international partnership between the Indonesian Ministry of Forestry and Tropenbos Foundation.
Borneo Orangutan Survival Foundation
In 1991 Smits founded what was soon to become the Borneo Orangutan Survival Foundation (BOS), in Kalimantan (Indonesian Borneo), the world's largest organization for the protection of the endangered Bornean orangutans. Two years before, Smits had had his first encounter with an orangutan in the market. It was a life-changing event and Smits often retells the story:
"Somebody stuck a crate in my face at the market in Balikpapan. Looking out between the slats were the very, very sad eyes of a baby orangutan. I couldn’t forget them. That evening I went back after the market closed. Walking around in the dark, I heard a horrible gasping sound. The baby in its crate was on the garbage dump, dying. I picked her up." 
He nursed her back to health and named her Uce for the laboured sound she made while gasping for breath. A few weeks later he was given another sick orangutan to look after, which he named Dodoy.
With the help of thousands of schoolchildren in Balikpapan contributing small amounts of money, Smits was able to set up what became the Borneo Orangutan Survival Foundation to rehabilitate orphaned and misused orangutans and return them to a safe place in the wild. Wanariset became home to hundreds of confiscated orangutans, rescued from illegal animal smuggling, kept as pets or exploited in other ways.
The Dutch orangutan-scientist Herman Rijksen recalls Smits creating the facility: "In no time he set up the most fantastic oversized quarantine facility, better than any hospital in the whole area, because that's typical of Willie. He wants to do it very, very good."
Smits quickly saw that protecting orangutans in their habitat not only benefits orangutans but also the environment, biological diversity, the poor in Borneo and all the world’s people. The activities of the Borneo Orangutan Survival Foundation expanded from rescuing, rehabiliting and releasing orangutans to monitoring, conserving and rebuilding rainforest, along with the social engagement that made this sustainable. Smits also took on an increasing campaigning and advocacy role, to make the plight of the orangutan and its habitat more widely known, along with the message that something could - and was - being done.
In 2001, BOS started purchasing land near Wanariset (deforested by mechanical logging, drought and severe fires and was covered in alang-alang grass (Imperata cylindrica). The aim was to restore the rainforest and provide a safe haven for rehabilitated orangutans while at the same time providing a source of income for local people. The name Samboja Lestari roughly translates as the "everlasting conservation of Samboja". Wilderness engineering in the form of reforestation and rehabilitation is the core of the project, with hundreds of indigenous species planted. By the middle of 2006 more than 740 different tree species had been planted.). The 2,000 hectares (4,900 acres) area it acquired had been
The Orangutan Reintroduction Project at Wanariset was moved to Samboja Lestari. "Forest Schools" were established, areas that provide natural, educational playgrounds for the orangutans in which to learn forest skills. Here the orangutans roam freely but under supervision and are returned to sleeping cages for the night. "Orangutan islands" were created where the orangutans and other wildlife that cannot return to the wild are nevertheless able to live in almost completely natural conditions.
At his 2009 TED talk Smits stated there had been a substantial increase in cloud cover and 30% more rainfall due to the reforestation at Samboja Lestari, the rainfall increase data being consistent with the absence of trade winds. When challenged, Smits cited the production of cloud condensation nuclei by rainforest as a possible mechanism to account for the observed data.
To finance the nature reserve, BOS created a system of "land-purchasing", a "Create Rainforest" initiative where people symbolically adopt square metres of rainforest. Donors are able to view and follow the progress of the purchase with their donation in the project area with Google Earth satellite images from 2002 and 2007 with additional information overlaid.
Smits is one of the founders of, and the chairman of the Masarang Foundation, which raises money and awareness to restore habitat forests around the world and to empower local people. In 2007, Masarang opened a palm sugar factory that uses thermal energy to turn the juice tapped daily from sugar palms (Arenga pinnata) into sugar or ethanol, returning cash and power to the community in the attempt to move toward a better future for the people, forest, and native orangutans, while saving 200,000 trees per year from being cut down as fuel wood.
In 1980, when Smits proposed to his wife, Syennie Watoelangkow (of royal blood) in Tomohon, North Sulawesi, he was surprised by the dowry: six sugar palms. At that time, a mature sugar palm that was ready to sap cost about as much as a chicken. Nevertheless, the people of Tomohon wanted sugar palms ("pohon aren") instead of gold as the dowry. "I wondered why it was that cheap," Smits says. Later he learnt the answer, calling the sugar palm a "magic tree". He says of the sugar palm. "From the roots to the leaves, every bit is beneficial for people. Those who eat palm sugar will live longer than those who use cane sugar." During his years of research in North Sulawesi and other places in Indonesia where sugar palms grow, he has learned that people are not making the most of the tree and its properties.
In North Sulawesi's capital, Manado, people sap the trees only to make their traditional alcoholic drink. People in other places sap the trees to make palm sugar or cut them down for sago. But the tree offers more. For one, nira, the white sap obtained, can be processed into ethanol. "My research shows no tree can produce alternative fuel as well as palm trees," Smits said. "Sugar palms can also help the environment. They are effective in preventing landslides, even on really steep land." The high-quality fibres from sugar palms are also widely used; Smits exports them to Europe, where they are among the materials used in the bodies of luxury cars.
Smits has opened a palm sugar factory in Tomohon, managed by his brother Theo Smits, which uses as fuel leftovers from the state energy company Pertamina’s geothermal gas production. Everyday, about 6,200 farmers produce nira for the factory, which is managed by the Masarang Foundation. The sugar is sold locally and exported to Hong Kong, Australia, Singapore and Europe, where it is known as Masarang Arenga Palm Sugar. He states his "productive, environmentally friendly factory" could become a model for other places in the country. "There are no less than eight provinces that have abundant sugar palms but they have not done much with them," he says. He believes that if Indonesia made the most of its sugar palms, then in two years there would be no need to import sugar any more. For this purpose, he designed, prototyped and patented the so-called Village Hub.
According to Smits' talks for Qi Global and TED, both Samboja Lestari and the Masarang foundation have evolved on the principles of People, Planet, Profit. Smits has demonstrated how community capacity-building and community empowerment can promote economic development while conserving the natural environment.
With a team of BOS staff and forestry officers, Smits confiscates orangutans kept illegally as pets. When an orangutan is confiscated from a home the family is given medicines to fight the parasites they may have contracted from the orangutan. (Smits himself recalls three days in hospital on chemotherapy to fight the lungworms and other parasites that threatened his life.
Confiscations are inevitably confrontational at times, and there have been numerous death threats made against Smits.
Primate Centre at Jakarta Zoo
Smits designed the Schmutzer Primate Centre at the Ragunan Zoo which opened in 2002  so that the orangutans have freedom and privacy in a habitat with a variety of forest trees and plants, a waterfall and water with turtles and fish, and small animals like porcupines and deer mice. Thick dark glass allows visitors to see the orangutans while being invisible to them.
Smits initially had no interest in zoos, but now sees it as a sanctuary for sick, injured and blind confiscated orangutans (the healthy ones are taken to Borneo Orangutan Survival Foundation rehabilitation centres for eventual release into the wild).
Smits has continued to be involved in the study of the mycorrhizal fungi that improve the uptake of water and nutrients from the soil by the meranti tree. By using this fungus he has achieved faster growth of young seedlings. He is beside his current work for the orangutans at Wanariset, the chairman of the Gibbon Foundation and consultant for the Indonesian Orangutan Survival Program.
In 2006 Smits launched TV 5 Dimensi, commonly referred to as TV5D, a North Sulawesi local television channel, based in Tomohon. His wife's family in North Sulawesi manages a beach about ten kilometers long, where sea turtles grow and visitors may see coral. Smits also rescues tropical birds from the illegal pet trade.
Smits received the first non-Indonesian Satya Lencana Pembangunan Award (1998). He has the equivalent of a knighthood from the Netherlands for his conservation work.

Thinkers of the Jungle - The Orangutan Report: Pictures, Facts, Background gives an account of the life, behaviour and fate of orangutans. Alongside a wealth of information about this endangered species based on the latest research, authors Willie Smits and Gerd Schuster outline the threat to the orangutan's survival: economical and political interests, exploitation of nature and human ignorance and greed.
The book is illustrated by more than 350 photographs taken by war photographer Jay Ullal.
In August 2007 the publisher Herbert Ullmann set off via Singapore and Jakarta for Balikpapan in Borneo. There he visited two orangutan rehabilitation centres run by Dr. Willie Smits. He was impressed both by the orangutans themselves and by Smits' work in rescuing and rehabilitating them: "There are books that can be published, and books that have to be published."
