How does wildfire affect soil carbon, the ecological currency of the 21st century? Careful collaborative research involving US Geological Survey scientists, Envu, and Boise State University has begun to answer some of the many questions surrounding soil carbon and fire. This is the first of a two-part interview on soil carbon storage, sequestration mechanisms, effects of wildfire and plant community shifts, and management implications.

AoR 147: Wildfire Depletes Ecosystem Carbon Storage by >50% (Part 1) -- Germino, Maxwell, & Quicke

Dr. Germino’s latest research, published in the Communications Earth & Environment journal in November 2024, reveals a startling and significant finding: invasive grasses are turning western U.S. rangelands from valuable carbon sinks into potential carbon sources. This research, a two-year collaboration between the US Geological Survey and Envu, provides the first comprehensive assessment of the impact of invasive annual grasses, like cheatgrass, on soil carbon stocks. The study found that the conversion of native perennial shrublands to these invasive grasslands can result in a 42-49% reduction in soil carbon, releasing a significant amount of carbon dioxide into the atmosphere. It also found that wildfire and grass invasion had a similar impact on soil carbon stocks, a surprising finding that challenges previous assumptions about the relative impacts of these disturbances. Dr. Germino is joined by another study author, Dr. Harry Quicke from Envu. They discuss implications of this new research for rangeland management and potential solutions. This is part 2 of the discussion. To hear the first part, go to episode 147.

Bildo Saravia is the owner and manager of Rancho el Ojo and Origien Raiz Mezcal. His story showcases the ways global marketing and communication can benefit local people oriented around rangeland economies. By "grazing the wild" he is growing agave in sustainable polyculture with a diversity of other native plants for livestock and wildlife in Durango, Mexico.

The Sterling Wildlife Management Area in southeast Idaho suffered from accumulated dead cattails, bulrushes, and grasses. Wildlife the area is intended habitat for were avoiding it, especially migratory waterfowl. This Life on the Range story with rancher Chase Carter and biologist Maria Pacioretty describes their successful efforts to use targeted grazing in winter to consume and transform the overburden of dead vegetation.

The concept of carrying capacity has figured prominently in rangeland ecology and wildlife biology for a century and more. Where did this term come from? Nathan Sayre, a cultural geographer at UC-Berkeley and the author of the book "Politics of Scale - a History of Rangeland Science," answers this question. 

According to Sayre, "It is a truism that the Earth’s resources are finite, and that human demands must therefore be kept within some bounds. But this idea has a history fraught with intellectual and political problems. My work on scarcity, carrying capacity, and related ideas explores how these terms and concepts emerged, traces their shifting meanings over time, and reveals their hidden assumptions and flaws." 

Our conversation centers around an article he wrote titled "The Genesis, History, and Limits of Carrying Capacity." The origins of the idea and the term, which has been controversial socially, ecologically, and economically, may surprise you.

Can Farmer-Founded Fibers Save American Fashion? Cate Havstad-Casad, founder of RangeRevolution leather goods, and Daniel Mouw, president of Duckworth wool clothing answered this question in a pre-panel interview at SXSW with Ed Roberson joining in. If Duckworth and Range Revolution are not on your radar screen, and if Mountain & Prairie Podcast isn't in your podcast feed, they should be now. Ed interviewed Cate and Daniel in a SXSW talk the day after we recorded this preparatory interview. We discuss  supply chain challenges, what is fashion, the recent renaissance of wool, and why natural fibers are superior to synthetics (let me count the ways).

Does grazing management make a difference? Can we raise livestock and wildlife and take carbon out of the atmosphere and put it in soil on the same piece of land? Meet Peter Byck, self-described scientist wrangler and producer of Roots So Deep, a four-part documentary series that explores the world of adaptive cattle farmers and their conventional farming neighbors. Adaptive multi-paddock grazing is one of the faces of regenerative agriculture. Listen to this interview to learn about researched results from caring for land well. The Roots So Deep documentary film series shows, rather than tells, how we can have our cake and eat it too -- how grazing patterns can increase soil carbon, increase wildlife diversity, reduce water runoff and soil erosion, and improve financial health of family farms.

Over 15 years ago, the veteran journalist Steve Stuebner and Idaho Rangeland Resources Commission executive Gretchen Hyde set out to use the new media landscape to tell good news stories about rangeland landscapes and the unique people who care for them. This has been a wildly successful venture that has reached far beyond the borders of Idaho. Listen to this interview with Steve and Gretchen about the recent "15-year retrospective" story and video on Life on the Range.

AoR 156: 15 Years of Life on the Range with Steve Stuebner & Gretchen Hyde

"Six patches make you six times less likely to be entirely wrong". Diversity and variability drive rangeland health. Healthy rangelands provide an array of ecological and social goods and services. Resiliency describes the robustness of natural mechanisms that allow land to continue providing those EGS over time with and through disturbance. Disturbances are necessary processes to create botanical diversity, but also changing diversity, across space and time. Human-caused disturbances should avoid pushing ecosystems over thresholds, tipping points, into new degraded stable states. Dr. Fuhlendorf says scientists and managers should "embrace ecological humility" and assume we know less than we think we do.
