The Campaign to Stop GE Trees

Genetically engineered trees pose risks of contaminating forests, damaging ecosystems and harming communities

Take Action

The goal of the campaign is to protect native forests, and to defend the rights of forest dependent communities and Indigenous Peoples from the unknown and irreversible risks of releasing genetically engineered (GE) trees.


Trees are being genetically engineered for traits such as faster growth, and disease resistance.


Catch up on recent news, events, articles and education resources about GE trees.


It’s time to mobilize! You can help end the threat of genetically engineered trees.


Arm yourself with information about GE Trees (also called GM Trees)

Sign the Petition

Tell the US Department of Agriculture to reject GE trees: Deadline October 19.

Add your name to stop US government approval of the widespread release of genetically engineered (GE or genetically modified) American chestnut trees into our forests. The risks are huge.

If approved, these GE trees will spread their pollen and seeds freely. This would be the first GE forest tree released in the US, opening the floodgates to others.

It would also be the first-ever intentional release of a fertile genetically modified organism (GMO) into wild ecosystems, opening the door to other uncontrollable GMO releases.

Engineers think they can (re) create nature in the lab, but neither trees nor any species can be replaced by with GE facsimilesDecades of progress to restore wild American chestnut trees would be lost. This is not restoration, but a dangerous open-air experiment.

There are no long-term risk assessments of this plan and scientists warn such assessments are not possible. American chestnuts can live hundreds of years and have deeply intertwined relationships with other trees, and with insects, songbirds and other wildlife.

Join individuals and organizations across the world in demanding the rejection of genetically engineered trees. We cannot allow this kind of dangerous experimentation with our forests.

Take Action: Say NO to Genetic Engineering in Our Forests!
