Our mission

Treesistance is a movement and an impact blueprint centered on the protection of the Amazon and other tropical forests of the world. Working at the intersection where Indigenous knowledge and science meet. We create disruptive models that have long lasting tangible impact.

Treesistance: Revolutionising Forest Crime Prevention and Biodiversity Protection

Treesistance distributes resources directly to the Indigenous people on the frontlines of the climate battle. All activities are Indigenous-Led and ran in consultation with the relevant Indigenous representative bodies in the region. Our mission is to stop the destruction of primary rainforest, protect biodiversity and uphold human rights.

In Partnership with Indigenous leader, Chief Dadá

“I am Dadá Borari, chief of the Maro Indigenous Territory. We are on the frontlines of the resistance to defend the forest and all life within.

We are taking back control from those who have lost their connection to mother earth and exploit the forest for profit. Our non-Indigenous brothers and sisters must remember they are part of nature and our collective survival depends on it.

Now is the time for us to unite if we want to pass on a healthy world for our children and future generations.

Nature is taking back its power. 

Join the fight of the decade.

Join the Treesistance.

Our guidelines respect and honour the following international commitments:

The Guiding Principles of the Conservation Initiative on Human Rights.

We are a Dutch based Nonprofit working with Indigenous peoples and partners worldwide. We have an inclusive culture guided by Indigenous wisdom, practices, and protocols. Our governing bodies, leadership, and staff are built upon diverse, non-Indigenous and Indigenous identities. As a bridging organisation, we view this diversity as a source of our strength.

Summary of OUR WORK

We believe that Indigenous peoples have the cultures, wisdom, and territories essential for humanity to navigate the climate crisis. Our focus is to direct financial support to those defending the most biodiverse regions in the world.

We believe that all decisions and policies that affect Indigenous peoples and their territories must be made with Indigenous peoples present and heard.

Our knowledge, information and learnings are open-sourced, so that all other Indigenous organizations can benefit.

We establish partnerships with Indigenous peoples,  communities as well as non-Indigenous organizations who work in solidarity with Indigenous peoples. In working with those who have global and /or regional knowledge, influence, and reach, we maintain equitable partnerships based on guidelines that promote open, honest, and transparent communication.

We support the passing of experience, training, and capacity to the next generation of Indigenous peoples and their chosen allies.

We commit to amplifying Indigenous voices. Our stories feature the reciprocal relationship between humanity and nature and tales of resistance, among other personal stories told by Indigenous storytellers.

We believe that to scale impact we must educate and create strong communities that can help amplify and share these messages.
