Become a friend of GTF, make trees live and grow with them!

Your support will allow us to study and defend the largest and most important trees on our planetand to ensure everyone a greener future.But, above all, will allow you to become the protagonist of an incredible exploratory journey into the crown of the most mysterious trees on our planet.

We wanted to build a card lasting three years, because the trees are moving but with times much slower than ours! That's why we want to have a commitment with a longer life than a single growing season. Gift today and remain registered for three years! 

Long Live the Giants!
