Threshold is a Peabody Award-winning documentary podcast about our place in the natural world. Each season, we take listeners on a journey into the heart of a complex environmental story—about a species, a place, an idea, a controversy, or a question—that we think deserves attention.

It’s a show as much about relationships as it is about the environment. And relationships are complicated. Threshold steps into that complexity, revealing the challenges and possibilities in our relationship with the planet.

We go where the narrative unfolds and feature perspectives from those most invested, impacted, and involved. We engage science, history, culture, and politics to create a nuanced view with big ideas at the center. But most of all, there are great stories—told with beauty, sadness, joy, outrage, humor, heartbreak, and wonder.

The result is an open invitation to think about what it means to be alive, in awe of our natural world, in this time of extraordinary planetary change.

Created by host and executive producer Amy Martin, Threshold first aired on Montana Public Radio in 2017. The show has been recognized by top publications, has received a number of journalism awards, and has over a million downloads. Season 5: “Hark” is out November 19, 2024.

Threshold is nonprofit, listener-supported, and independently produced.
