To celebrate these woodsy wonders, we’ve gone into our library to find eight amazing talks on trees. Watch them all below:
Ginormous trees have big effects | Steve Hart | TEDxYosemite
When most people are looking the very, very tall sequoia trees of California, Dr. Steve Hart is looking down — investigating how these massive plants affect the local soil and ecosystem. These special trees leave a very specific imprint on the environment, Hart says, and it is his job is to make sense of it.
The return of the chestnut — a tree crop archetype | Hill Craddock | TEDxUTChattanooga
The American chestnut tree was almost wiped out in a 1904 pandemic, says Dr. Hill Craddock at TEDxUTChattanooga, but thanks to the work of citizen scientists, it is on its way to an impressive comeback, he says. Watch his talk to learn how disease-resistant American chestnuts are being bred.
An archive of ancient tree genes | David Milarch | TEDxNASA@SiliconValley
David Milarch is the head of the Archangel Ancient Tree Archive, an organization dedicated to preserving ancient tree species in the U.S. To do so, the team at Archangel uses tissue samples to clone very, very old trees. At TEDxNASA@SiliconValley, Milarch explains just how that works.
No me, no tree | Tim Pearson | TEDxCanberra
At TEDxCanberra, biologist Tim Pearson shares facts about one of the Australian gumtree’s main allies — the fruit bat. These productive pollinators help the trees survive, Pearson says, and he thinks we should appreciate their hard work.
Why I love street trees | Victor Dover | TEDxCoralGables
In this enthusiastic talk, urban planner Victor Dover makes a case for why you should love “street trees” — urban trees lining streets — and shares how they help a city thrive.
Why everyone should have a tree | Beatrice Puijk & Raymond Brouwe | TEDxMaastrichtSalon
At TEDxMaastricht, Beatrice Puijk & Raymond Brouwe share how they started an initiative to encourage city-dwellers to grow trees on their balconies.
The case for GM trees | Gail Taylor | TEDxSouthamptonUniversity
Could genetically modified trees be a source of green energy? At TEDxSouthamptonUniversity, Dr. Gail Taylor shares research on producing trees optimized for creating biofuels.
Out on a limb — physical therapy via tree climbing | John Gathright | TEDxKyoto
In a delightful talk at TEDxKyoto, Dr. John Gathright shares how he got into researching the health benefits of climbing trees — a project that led to many, many trips up trunks and out on limbs.
