Nancy Smith is the Conservation Director for The Nature Conservancy’s Colorado River Program, and Austin Rempel is the Riparian Restoration Program Manager at The Nature Conservancy. Both Nancy and Austin are working on the front lines of some of the West’s most innovative water and habitat conservation projects– projects that benefit everything from groundwater supplies to wildlife habitat, climate resiliency to ecosystem health.

If you’ve listened to many of these TNC-focused episodes, then you’ll know that TNC works extensively throughout the Colorado River Basin on a wide range of conservation issues that affect people, wildlife, and landscapes. In this episode, we’re going to zoom in on one very specific, very simple, and very effective process that has the potential to have massive positive impacts on ecosystem health throughout the West.

-

The process is called “low-tech process-based restoration,” which is the practice of adding simple, low-cost structures made of natural materials like rocks, wood, and posts to simulate natural processes like beaver dams in streams and wetlands, kick-starting natural cycles of recovery. These structures require minimal permitting, can be built quickly by hand without heavy equipment, use locally sourced materials, and can be installed by local workers who do not need extensive training. The end result creates surprisingly effective outcomes that can be scaled quickly across vast stretches of the West.

We recorded this conversation the day after Colorado River Day, which was a fitting time to highlight such an important project and process. We started out by discussing how this project came to be, which involved a significant amount of funding from the Inflation Reduction Act. We discuss how rivers have historically looked in the West versus how they look now, as well as the ecological complexities of riverscapes and riparian corridors.  We then dig into the details of “low-tech process-based restoration”-- timelines, challenges, opportunities, partnerships, and measuring success. We also talk about beavers, shifting cultural norms around conservation, overlaps between forest and riparian restoration, favorite books, and much more.

-

As you’ll hear, Nancy and Austin provide such an excellent overview of several varieties of low-tech process-based restoration. But for those of you who want to dig deeper into details of the various processes and case studies, they’ve provided me with extensive additional resources that you can access in the episode notes. I’d also encourage you to check out the short film embedded on the episode’s webpage, which will give you a visual overview of the process and its results.

A big thanks to Nancy and Austin for the fun conversation, and thank you for listening.
