Dr. William Keeton: Carbon, Complexity, and the Future of Old Growth

Dr. William Keeton is a forest ecologist and silviculturalist at the University of Vermont who has spent most of his career studying old-growth forests in the eastern United States and around the world. In this conversation, he joins hosts Bill Hodge and Anders Reynolds to examine what old growth actually is, where it still exists in the East, and why its fate matters for climate, biodiversity, and the landscapes future generations will inherit.The episode opens with a deceptively simple question: what is an old-growth forest? Keeton explains that old growth is not a fixed condition but a stage of forest development characterized by structural complexity, habitat diversity, and a suite of ecological functions including carbon storage, hydrologic regulation, and biodiversity support. He pushes back on the assumption that eastern forests have nothing to offer compared to towering Pacific Northwest Douglas firs or coastal redwoods, walking through the surprising inventory findings of the past few decades that reveal far more old growth in the eastern United States than was previously believed, from the Adirondacks of upstate New York to the Southern Appalachians and the longleaf pine systems of the Gulf Coast. The conversation also takes the listener below the surface, into the soil, where Keeton discusses the growing understanding of mycorrhizal fungi networks, deep soil carbon, and why a recent study found Swedish old-growth forests store eighty-three percent more carbon than middle-aged forests, with most of that difference buried underground.For listeners who care about public lands, forest policy, and the long arc of ecological recovery, this is a conversation that connects the science to the stakes with rare clarity.
