Trees for Arbor Day...first, from Nature on PBS, Saving Giant Sequoia Seeds for the Future, followed (below the jump) by a PBS story on Pando (the biggest aspen clone ever identified) in Utah. Then, via United Nations, a clip from Climbing Redwood Giants. Next, Moreton Bay Figs at The National Tropical Botanical Garden on Kauai. Last, Ranger Amy Washuta talks about cypress trees at Big Cypress National Preserve.
