Who We Are
Ascending the Giants is a volunteer group of tree enthusiasts, arborists and researchers dedicated to documenting trees. Although our headquarters are based in Portland, our team is international and our work, likewise, aims to reach wherever forests exist.
What We Do
Measuring trees is our main focus. In tandem, Ascending the Giants also offers access for canopy research, film production companies, and adventure tree climbing.
Our work mostly consists of an ongoing series of expeditions to measure the largest tree of each species. These trees demonstrate the pinnacle of what a species can be; they are called champion trees. We archive and share information of these specimens to increase knowledge of their existence and their ecological importance.
