Filmed by Emmy Award-winning cinematographer Al Giddings, this timeless program takes a stirring look at the largest, tallest, longest-living things on the planet: trees. Stunning location footage captures the variety and the grandeur of the Pacific Northwest, the Florida Everglades, the Shenandoah Valley, and the Great Sonoran Desert. Quotations from Sierra Club founder John Muir and others who revere nature are interwoven with information on topics ranging from the function of forest ecosystems, to the effects of deforestation, to the integration of parks into urban landscapes.
