Combining a natural history of trees with a wider look at their significance in our culture and their importance to our civilization, this immersive and gorgeously illustrated Smithsonian guide profiles 90 favorite and extraordinary species. Here are gnarled oaks and towering redwoods, sacred banyans and otherworldly baobabs, ancient aspens and imposing kapoks, seen not only in dramatic photos but also striking artworks and vintage illustrations. We see not just their life cycles and inner workings but also how they provide vital support for the other inhabitants of our planet, from fungi to humans.
