”Cryphonectria parasitica claims its 8 millionth victim. We gotta get this bastard”
New show that’s just a detective showing up at the scene of a dead tree and then we learn tree facts about that specific type of tree and an in-depth region history of all the stuff the tree lived through.

The canker at the base of this scarlet oak is chestnut blight, caused by Cryphonectria parasitica. It weakens the tree but does not kill it outright. As long as scarlet oaks exist, chestnut blight will persist. The only hope for American chestnut is breeding and selection for resistance.

🌿🌰 I went and visited the nearest piece of public land to this site and found something almost as rare: an American chestnut | Castanea dentata.
These functionally extinct trees, which resprout from their early 20th century roots, are uncommon in the mountains, but truly rare in the coastal plain
