Trees are the most complex and successful plant species on the planet. Almost one third of the earth is covered in trees. They come in all sizes, from the smallest artic willows to the tallest Californian redwoods. Most tree species outlive humans many times and some are thousands of years old. Trees inspire us with their beauty and root deep in the human psyche. Fairy tales, poetry, art and literature all often inspired by the beauty and mysteries of trees.
