Redwoods are in the news this week, reminding the world once again that Earth’s tallest trees are truly ecosystems in their own right. Teeming with life from quite literally their roots to their highest leaves, the magnificent coast redwoods are home to hundreds of other species. With the pioneering redwood canopy research that began in the 1990s with Professor Stephen Sillett at Humboldt State University, we continue to learn and understand more about the lichens, mosses, ferns, and wildlife that reside hundreds of feet off the ground every year. New discoveries about the diversity of life in the redwood canopy are made possible due to the scientists who carefully ascend into the forest canopy to meticulously catalogue the array species that need our protection along with the coast redwoods trees themselves.
Next time you hike among the redwoods, look for fallen redwood branches and notice the spectacular variety of lichens that cling to bark. Lichens come in all shapes and sizes and who knows, maybe you’ll discover a species we haven’t yet found!
