forest canopy

High up in the canopy of an old growth forest, there exists an extraordinary world hardly known to most of us on earth. For centuries, people have admired the sheer size of redwood trunks and appreciated the bounty of ferns and sorrel that carpet the forest floor. We have cherished the rare silence that envelopes the trees and relished in the beauty of sunlight filtering through the underside of the canopy. Yet, the intricate world at the top of the trees remained a mystery until the late twentieth century, with the advent of canopy exploration.
