Recorded in the heart of Tilburg—a Dutch city that has transformed from one of Europe’s hottest urban heat islands into a showcase of regreening—this episode explores the hidden worlds that decide whether city trees live or die. Arborist and Senior Advisor Erwin van Herwijnen of New Urban Standard joins the Internet of Nature Podcast to talk about why soils matter more than species, and how climate-adaptive growing places can turn trees into the new sewer system.

We discuss why most city trees never make it past adolescence, why climate-ready trees won’t save us without climate-ready soils, and how stormwater makes or breaks survival. Erwin explains why tree professionals can’t afford to be “softies,” why spreadsheets might be the Lorax’s greatest ally, and how making civil engineers happy is the secret to long-lived urban forests.

Plus: the tragedy of cutting down trees before they reach maturity, what it takes to plant for 80 years instead of election cycles, and why, for Erwin, the city only truly comes alive when its people can sit in the shade of a tree.
