Bonus Ep: Suzanne Simard and the Social World of Trees

What if, instead of competing with each other, trees work together? What if they even communicate? Renowned forest ecologist Suzanne Simard has spent her life digging into the "wood wide web"—the mycorrhizal network of fungi and roots through which trees share resources and information. Her work has transformed the way we understand forests and inspired everything from the Tree of Souls in "Avatar" to the scientist character in "The Overstory."

We talked with Simard about her new book, "Finding the Mother Tree: Discovering the Wisdom of the Forest," for her book launch at Powell's Books. Prepare to have the way you view forests and trees flipped on its head.

Salmon are essential to Columbia River tribal people. These fish represent not only a food source but a way of life. As a white kid growing up in the Pacific Northwest, Tony Schick heard a lot about salmon — how important they are to this region, and how much trouble they’re in now. But the history he learned was not the whole story. As an investigative reporter for OPB and ProPublica, he’s been working to uncover and understand a more sinister version of events. And along the way, he connected with a guy named Randy Settler and his family.

“Salmon Wars,” a production from OPB and ProPublica, tells the story of salmon in the Northwest in a way you haven’t heard before – through the voices of one Yakama Nation family  who have been fighting for salmon for generations. We’ll dive into hidden history. We’ll investigate who’s to blame for the salmon vanishing, and what can be done before it’s too late.
