Into the Woods, From Chestnut Genetics To Tiny Forests

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.
