Ecosia for the conservation of biodiversity and wilderness

Since September 2026, the sustainable search engine Ecosia has been supporting Wilderness International in safeguarding ecologically valuable conservation corridors in Manu, Peru – one of the most species-rich places on Earth. Thanks to Ecosia’s commitment, we can permanently preserve this unique old-growth forest with its extraordinary biodiversity and prevent its impending destruction caused by road construction, deforestation and oil drilling.

As one of the first partners, Ecosia established its own corporate forest in the Secret Forest Manu and helped fund a six-part documentary series about the adventurous expedition into the new protected area – featuring presenter and conservationist Hannah Emde.

Ecosia is a search engine dedicated to the public good that invests 100 per cent of its profits in climate action. With over 250 million trees planted worldwide, Ecosia supports tree-planting initiatives, the restoration of ecosystems, and investments in renewable energy and other climate protection projects.
It’s already happening in the Secret Forest of Manu: here, the forest is being preserved because the local people are protecting it and because many people here are helping through their everyday searches. At Ecosia, we’ve planted over 250 million trees, but no new tree can replace an intact primary forest like this one. Our vision is an internet that gives back more to the planet than it takes. This includes safeguarding forests before roads and drilling rigs arrive.

Join vet and conservationist Hannah Emde on a journey to Wilderness International’s new protected area in the Peruvian Amazon rainforest. In the south-east of Peru lies the province of Manu, one of the most biodiverse places on Earth. Yet human interference, illegal deforestation and ongoing destruction are threatening this precious ecosystem and its fascinating biodiversity more acutely than ever before.

The six-part documentary series “Secret Forest Manu” is now on YouTube.

Research & Collaboration in Manu

Every square metre counts.

Together, we can make an even bigger difference: every donation to the Ecosia Forest protects the irreplaceable habitat of plants, animals and people, legally secured by a land registry entry and for all time.

Transparency

Why old-growth forest protection with WI?
Ecosia was impressed by Wilderness International’s holistic approach: the long-term protection of ecologically valuable old-growth forests through legally secure land acquisition combines a concrete, transparent and traceable contribution with a long-term, effective means of combating species extinction and the climate crisis. As a charitable foundation, Wilderness International uses donations in a targeted manner to protect critically endangered forest areas – as the basis of our livelihoods and for future generations – forever.

Frequently Asked Questions

  • What does Wilderness International do?

    Wilderness International purchases wilderness areas in a legally secure manner and protects them for the long term. These purchases are funded by donations, which not only ensure the long-term protection of the areas but also enable environmental education projects and research into CO2 sequestration and biodiversity. Donors receive a personalised certificate showing the exact geographical coordinates of the protected forest area, so that the protection can be directly traced. We are currently active in the temperate rainforest of western Canada and the Amazon rainforest of Peru, where we are protecting ancient primary rainforests.
  • Why is it important to protect the rainforest?

    It is important to protect the rainforest because this is the only way we can halt species extinction and climate change. They are home to the greatest biodiversity in the world and store huge amounts of CO2. It is also important to protect rainforests because they are the basis of our existence: they provide us with clean air, clean water and a stable supply of rainfall. They also help to cool the surrounding environment. 
  • How can we ensure that the protected area is preserved for all time?

    In Canada, we are aided by the high level of legal certainty – or rather, the legal framework – and the penalties, which even prohibit trespassing, as well as the cultural and historical significance of property.

    In Peru, we have also launched a forest ranger programme in collaboration with local people. We have put several measures in place to ensure long-term protection. Generally speaking, we visit the areas on regular expeditions to check that everything is in order. We also work with local partners who inform us if necessary. The donations per square metre also already include the costs of property tax.

    The legal form of the foundation, unlike any other, allows a (charitable) purpose to be realised permanently and independently of external interests, thereby achieving the desired long-term effects. It is thus the most long-term organisational structure currently known. Not even states, companies or national parks are designed with such a long-term perspective. This makes the foundation the only organisation oriented towards the lifespan of the ecosystems we protect.

  • Who is Wilderness International and what does the organisation do?

    Wilderness International is a non-profit environmental organisation with a single goal: to protect the Earth’s last remaining unique forests and wilderness areas for ever. To this end, Wilderness International purchases plots of land through registration in the land register, thereby ensuring their legally secure and permanent protection. The land purchases are funded by donations towards so-called ‘wilderness sponsorships’. Wilderness sponsors receive a personalised certificate stating the exact geographical coordinates of the protected area of woodland.

    WI Germany and WI Canada were founded in 2008 by 25 people from six countries, representing 24 different professional fields and aged between 18 and 69. In 2019, the Peruvian organisation dedicated to protecting the tropical rainforest joined the network. Today, Wilderness International consists of three sister foundations: 

    Behind Wilderness International Germany, in addition to the founding donors, are eight members of the Board of Trustees, three members of the Executive Board, our operational team, many volunteers and countless donors, partners, sponsors and supporters. You can find out more on the “Wilderness International Germany” page.

    At Wilderness International Canada, alongside Tobias Hürten and Kai Andersch, Marco Lou, Tyler Bruce and Stephen Gabrysh also work directly on the ground to manage our partnerships, land acquisitions, expeditions and the protection of our forest areas. Volunteers, donors and supporters are also actively involved here. You can find out more under “Wilderness International Canada”.

    At Wilderness International Peru, the seven founders form the board of trustees. On the ground, the organisation’s president, Dr Chris Kirkby, works alongside a team of forest rangers and the rest of the operational team to oversee the protected areas, carry out research and biodiversity monitoring in the forests, the search for and purchase of new plots of land, and projects with local schools, communities and partners. You can find more information on the “Wilderness International Peru” page.

  • What role does the tropical rainforest play in Peru?

    More than half of Peru’s land area is covered by forests. This makes the country home to the world’s fourth-largest area of tropical rainforest – after Brazil, the Democratic Republic of the Congo and Indonesia. In 2018, 87 per cent of this area was still virgin forest. The forests of the Amazon Basin are the largest contiguous rainforests on Earth. This means they are not only a huge CO2 sink, but also generate their own weather – a unique water cycle that carries rain from the Atlantic up to 5,000 km into the west of the continent. The only thing that sustains this water cycle is the vast extent of the contiguous rainforests. 

    At the same time, the Amazon rainforests play a vital role in cooling the surrounding environment and purifying the air of pollutants. Over the millennia, these rainforests have also produced the oxygen in the atmosphere that is essential for our survival. Furthermore, the rainforests in the Madre de Dios region are considered the most biodiverse place in the world! Due to favourable climatic conditions and geological history, there are 10 times more reptiles and amphibians here than in Germany. Around 10 per cent of all the world’s bird species can be observed there, and on one hectare of forest you can find around 400 tree species – more than in the whole of Europe north of the Alps! 

    Unfortunately, however, the forest is under serious threat: according to the Food and Agriculture Organisation of the United Nations (FAO), between 2015 and 2020, around 10 million hectares of tropical rainforest were lost each year, with the Amazon region suffering the most damage annually. In 2020 alone, an area of primary forest the size of Israel – that’s more than 22,000 km2 – disappeared.

  • How do you ensure the long-term protection of these areas?

    We protect the areas we have selected exclusively by purchasing them and registering them in the land register, and only in countries with a high level of legal certainty. All three international foundations (Peru, Canada, Germany) are registered as owners in the land register. The forest areas we have purchased as foundations can no longer be bought from us, and we are also prohibited from selling them. 

    The foundation’s organisational structure prevents the rights to dispose of the property from resting with a single individual and ensures its long-term survival. You can find out more about the longevity of the foundation concept here. Our articles of association stipulate that the plots of land must be left undisturbed and may only be visited for research and documentation purposes. 

    In Canada: 

    Due to their remoteness and the fact that the area is undeveloped, our protected areas in Canada can only be reached at great financial, material and time-related expense, and not without risk. Furthermore, the high level of legal certainty in Canada ensures that damage to land results in severe penalties. The British Columbia Trespass Act explicitly prohibits trespassing on private land. Violations are prosecuted in court upon complaint, even if no damage has been caused. Furthermore, we visit and monitor the areas as part of regular research trips and have partnerships with local companies that support us. In Canada, we also benefit from the fact that property is held in very high regard for its cultural and historical value and is respected.

    In Peru:

    In Peru, we have Forest Guardians on the ground, whose day-to-day duties include monitoring our protected areas and preventing unauthorised entry. By using drones, the Guardians can survey a larger area, and special sensors trigger an alarm instantly if, for example, a fire breaks out or the sound of chainsaws is detected. In addition, we work there with the organisation ‘Fauna Forever’, which also maintains a permanent presence on the ground and, as part of its research projects, patrols our areas alongside us, thereby helping to monitor them.

    Furthermore, the Forest Guardians are in direct contact with the local population, champion our conservation cause within the community, erect information signs and actively work on community projects – such as our current agroforestry project – to show the local population ways to benefit from the rainforest without clearing it. Should a conflict nevertheless arise, we report poachers and other individuals engaged in illegal activities to the local law enforcement agencies (such as the police, lawyers and authorities), and work closely with them.
