Carli Kierstead – Wyoming Forests and the Work of Keeping Water Flowing
Mountain & Prairie with Ed Roberson
Drivers of Beetle Outbreaks and Forest Vulnerability
Ed asks why beetle kill happens; Carli explains interacting factors: warmer temperatures, tree stress from drought, and compounding disturbances.
Carli Kierstead is the Forest Program Director for The Nature Conservancy in Wyoming, where she leads efforts to understand and restore some of the West's most critical—and often overlooked—ecosystems. From beetle kill and wildfire to drought, Wyoming's forests face a range of challenges that ripple far beyond the state's borders. These high-country forests are the headwaters of several major river basins, providing water to millions of people across the American West.
In this conversation, Carli and I dig into the past, present, and future of Western forests—how management philosophies have evolved over the decades, what's threatening their health today, and what can be done to make them more resilient in a changing climate. We talk about her team's groundbreaking work using snowtography—a deceptively simple but powerful way to study how forest structure affects snowpack and water supply—and how those findings could help guide future restoration across the Colorado River Basin.
Carli also shares her personal journey from growing up in San Diego to finding her calling in Wyoming's wide-open landscapes, her insights on collaboration and trust-building in conservation, and a few book recommendations that shaped her path. It's a hopeful, science-grounded conversation about water, forests, and how collaboration can shape a more resilient future for the West.
Thanks for listening, hope you enjoy!
