Episode Description from the Publisher

Summary The general impression that many people have is that prior to European settlement the whole eastern U.S. was one giant old growth forest. But that wasn't the case. Using an interdisciplinary approach, researchers over the last several decades have discovered that the eastern U.S. was instead interspersed with a surprising number of diverse ecosystems – only one of which was old growth forest.   3 things you'll learn from this episode: What researchers now think the eastern U.S. looked like 400 years or more ago. Why we have so many trees now and why it's so easy to believe that everything was once forest. Why all of this matters and what we should do about it.   Additional Resources: Forgotten Grasslands of the South: Natural History and Conservation *  2013 Harvard University - Smithsonian study  2025 State of the Birds Report  * affiliate link – We receive a small commission for purchases made through these links, but it comes at no extra cost to you.
