Matt Cahill is the Sagebrush Sea Program Director for the Nature Conservancy. Based out of Bend, Oregon, Matt leads all of TNC's critical work restoring, managing, and protecting sagebrush habitat across six western states. This is a huge and complex effort– it combines protection and policy work with ground-breaking restoration advances, public and industry partnerships, and local community projects. But as you'll hear in this conversation, Matt is optimistically leaning into the challenge and making great strides to protect this uniquely Western ecosystem.

-

To give you some context into the vastness of North America's sagebrush ecosystem, it spans 150 million acres and is home to 350 rare, threatened, and endangered species. Since 1998, 14 million acres of sagebrush ecosystems have been lost, and currently, we're losing approximately one million acres to invasive species, catastrophic wildfires, development, improper grazing, and climate change. 70% of the Sagebrush Sea is found on public lands, so efforts to protect, manage, and restore the ecosystem are dependent on creative, action-oriented public-private partnerships. Again, Matt is leading a huge and complex effort!

-

In this episode, we start our conversation by discussing why the Sagebrush Sea is important, and why even people who live far from the ecosystem should care about it. We discuss the history of the threats to sagebrush and do a deep dive into the specific threat of cheatgrass– a true scourge on the landscapes of the West. We discuss the ecology of sagebrush, how TNC measures success when it comes to protecting such a fragile ecosystem, and the importance of partnering with ranchers. We talk about the efficacy of for-profit approaches to restoration, collaboration with government agencies, and specific cutting-edge approaches to restoration. Matt also explains his career trajectory that led him from the East Coast to becoming obsessed with sagebrush, and he offers several great book recommendations.
