The tree-climbers from California

POVZETEK

Rick Dirks is one of the best tree climbers in California. He is able to climb 100-meter tall (328-foot) redwood trees with skill and courage and do so at breathtaking speed. He even ties himself to the crown of these giant trees in a sleeping bag for the night. In addition to trimming the trees and installing measuring tools, Rick collects the tree’s cones and seeds at dizzying heights - because the redwoods can only continue to survive if they are cultivated. In California, these giant trees are still cut down for timber.
