American chestnut trees once towered over the landscape, dominating forests in parts of the eastern United States. But in the late 1800s, a fungal blight virtually wiped them out across the country. Chestnut restoration scientist Jared Westbrook tells Host Ira Flatow how new genetic work could speed up efforts to breed fungal resistance into hybrid chestnuts and create a heartier chestnut population. Then, author Hanna Lewis introduces Ira to the concept of miniforests, self-sustaining native forest ecosystems on a tiny footprint, like an empty lot or a schoolyard. The planting method, developed by botanist Akira Miyawaki, can help “rewild” small parcels of land by jump-starting forest development. Read our full story, The Miniforest Movement Gains Ground In The U.S. Guests: Dr. Jared Westbrook is Director of Science for the American Chestnut Foundation in Asheville, North Carolina. Hanna Lewis is the author of the book Mini-Forest Revolution: Using the Miyawaki Method to Rapidly Rewild the World. She works for non-profit Renewing the Countryside in Minneapolis, Minnesota.Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.
