Ascending the Giants

Ascending the Giants is a non-profit organization that produces 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. With the support of videographer John Waller the team is able to capture some of the first and only footage inside the canopies of these remarkable trees. Ascending the Giants now showcases these specimens as a means to increase knowledge of their existence and their ecological importance in our forests and our community. Our owner, Damien Carre, volunteers his time with this organization by holding a Board position, participating in treks to document trees and through educational forums as a guest speaker and professional in the field of arboriculture.

Expedition Old Growth

Imagine a view that so very few people in the world have experienced. You see the photos, hear the stories and know they just do not give justice as compared to soaking it in yourself. Life amongst the old growth trees – experience, learn and appreciate.

Based in the Pacific Northwest, Expedition Old Growth provides tours of the region’s beautiful forests while assisting adventure-seekers with their guided ascent to the upper most canopies of the majestically ancient trees. Along the way, we create a greater appreciation for the living habitat and unique flora thriving at the forest floor and up into the tree-tops. Visit them at http://http://expeditionoldgrowth.com

Canopy Watch International

Canopy Watch International is dedicated to making forest canopies worldwide a target for science, education, and conservation. We seek to inspire curiosity and passion for one of Earth’s last unexplored spaces by taking our audience to the forest canopy via the sharing of videos, sound files, and conversations. We highlight scientific questions on our website and actively pursue and promote scientific research on the ecology of canopy systems. We conduct canopy expeditions as a way to share our excitement for the canopy, and attract international attention to this unique realm. Last, we take people into the tree tops so they can appreciate life at the top of the world. Visit them at http://canopywatchinternational.org
