A Note on Tree Climbing Ethics

Our work allows us to climb in some of the most beautiful and ecologically significant forests in the world. Studying forest canopies far above the forest floor is essential for deepening our understanding of these incredible ecosystems. We are extremely grateful for this opportunity, and thank land managers that have granted us permission to conduct research in such special places. 

Unfortunately, there has been an increase in the frequency of illegal tree climbing in old-growth forests on Park and other public lands in California and elsewhere. We believe that recreational tree climbing is a legitimate activity which helps connect people with nature and increases appreciation for trees and forests. However, old-growth forests are sensitive and fragile ecosystems which are easily impacted by tree climbing, and climbing is not allowed in any California State Park, National Park, or other public land except where authorized by a scientific research or other special use permit.

There are precious few remaining old-growth forests. Please respect the trees, forests, and land managers who are responsible for protecting these extraordinary resources by not climbing illegally. If you are interested, we encourage you to find responsible and legal opportunities to climb or explore forest canopies through canopy walkways or guided climbing tours in California and elsewhere. Feel free to contact us if you would like more information on such opportunities.
