Sean Claffey is the Southwest Montana Sagebrush Conservation Coordinator at the Nature Conservancy, a role that places him at the center of one of the West’s most overlooked but critically important ecosystems: the sagebrush steppe. Based in Dillon, Montana, Sean works across public and private lands to protect and restore this sprawling, foundational landscape that serves as habitat for countless species, supports rural economies, and connects the region’s valleys and mountain ranges. Through his leadership in the Southwest Montana Sagebrush Partnership—a collaborative effort uniting agencies, landowners, and nonprofits—Sean helps ensure that the health of this “land in between” doesn’t fall through the cracks.

In this conversation, Sean and I dig into the complex threats facing sagebrush country, from invasive grasses and wildfire to conifer encroachment and land conversion. We talk about how fire suppression and ecological shifts have allowed evergreens like Douglas fir and juniper to overtake sagebrush, and how Sean’s team is using a mix of prescribed burns, manual thinning, and innovative partnerships with local mills to restore balance to the landscape. He also shares how they’re engaging young people in hands-on restoration work, creating pathways for rural youth to connect with the land and gain meaningful employment.

Sean brings a unique blend of scientific insight, community-mindedness, and boots-on-the-ground experience to this work, and he’s quick to credit the collaborative culture of southwest Montana for making so much progress possible. From low-tech wet meadow restoration to building a more resilient restoration economy, this is a hopeful, grounded conversation about how conservation can succeed when it centers people, place, and purpose.

If you’re a new listeners and want to go deeper on this subject, I’d encourage you to go back and listen to my earlier episode with Matt Cahill who gives an excellent crash course on the Sagebrush Sea and the epsiode with Austin Rempel and Nancy Smith, who dig deep into riparian restoration in Montana.

But for this episode, be sure the check out the webpage and episode notes for some excellent videos about Sean’s work and links to everything we discuss. Thanks for listening.
