BOS Germany advocates for orangutan and rainforest protection
Our history
BOS Germany was founded in Kiel in 2001, ten years after the establishment of the BOS Foundation, initiated by physicians Dr. Jochen-Peter Collin († 2013) and Dr. Eberhard Kreikemeier († 2017), both of whom had previously worked in Indonesia, along with Berlin oral surgeon Dr. Dr. Klaus U. Schendel († 2015). Since 2003, BOS Germany’s headquarters have been located in Berlin. During this period, several new BOS organizations were also established in Europe and Australia.
The BOS Foundation was founded in 1991 in Balikpapan, Borneo, by Dutch forestry scientist Dr. Willie Smits, who was working in Indonesia at the time, along with teacher Peter Karsono and others. Initially, BOS (Dutch: forest) stood for Balikpapan Orangutan Society and was later renamed Borneo Orangutan Survival.
From 2003 to 2010, Boris Thiemig served as the Executive Chairman of the association, with Martina Wiesmayr. During these years, the organization evolved from a small entity into a substantial NGO, specializing not only in orangutan protection but also in palm oil and reforestation issues.
Following a change in the articles of association in 2010, Leonhard “Löwe” Graf Rothkirch became the chairman of the board of BOS e.V., which has operated on a purely honorary basis ever since. During this time, new thematic areas emerged, including community development, large-scale rainforest protection, rewetting of peatlands, and a focus on orangutan repatriation.
In September 2013, BOS Germany joined the Initiative Transparente Zivilgesellschaft.
Our Vision
We are convinced that it is now our collective responsibility to ensure the survival of orangutans and the Indonesian rainforest. Together, we strive to increase the orangutan population, preserve the Borneo rainforest and its biodiversity, and deliver benefits to both people and the climate.
A mission for the future
- Orangutan Protection: We rescue orangutans worldwide from illegal captivity and emergency situations. In our two rescue centers in Borneo, we rehabilitate liberated and orphaned orangutans, releasing them into secure conservation areas. For orangutans that cannot be reintroduced to the wild, we provide sanctuaries for a dignified life. To achieve this mission, we collaborate closely with the Indonesian BOS Foundation and an international network of partner organizations.
- Rainforest Protection: In multi-actor partnerships, we preserve and expand the habitat for orangutans in Borneo. Working together with the local population, we implement projects for sustainable community development and reforest degraded areas.
- Research: In collaboration with international scientists, we contribute to valuable research on orangutan behavior, species conservation, and the climatic importance, especially of peat swamp forests.
- Public relations and education: In collaboration with international scientists, we contribute to valuable research on orangutan behavior, species conservation, and the climatic importance, especially of peat swamp forests.
- Advocacy and political work: We consider ourselves advocates for orangutans. In dialogues with decision-makers, we provide advice and exert pressure for action on climate, forest, and species protection.
- Our Values: We utilize our resources efficiently and with a clear focus to achieve our goals. Transparency, cooperation on equal terms, and integrity are the core values to which we are dedicated. Donations entrusted to us are employed economically and responsibly.
