Tree Biology and Conservation Concepts

The video discusses the Team Trees initiative, aiming to plant 20 million trees by the end of 2019. It explores the history and survival of avocado trees, the efforts to revive the American chestnut tree, the mysteries of the dancing forests, and the science behind autumn leaves. It also highlights the longevity of trees like the Bristlecone pine and the Pando colony.
