At the roots of the world there was a tree, and only trees can save us!

Our promise

but our real dream is TO change THE WORLD.”

The ancestral tree, father of life, created the earth and the biosphere.
Its existence is necessary for the health and growth of all younger beings in the forest.
Vigorous forests support the populations they coexist with, stabilizing climate and biosphere of those nations that protect them.

This is why we search for the oldest trees and measure the highest.
We want to know them, defend them, treat them and respect them.

Long live the giants!

About us

Love for plants has united us for over 30 years and eternal trees will keep intact the memory of our passion if we know them and defend them.

That's why I wanted to create the GTF in memory of my husband
