Cattle growth goals and livestock use of large, topographically challenging landscapes have been at odds for some decades. Weaning weights went up, cow weights went up, and herd distribution on rangelands went down. Dr. Jim Sprinkle, an Extension beef specialist at the University of Idaho, has been doing research over those same decades that is providing guidance on developing cows that do both, leading to herds that are more efficient on feed and graze hillsides -- the Perfect Range Cow. This has significant implications for reducing land use conflicts, particularly with riparian grazing concerns on public lands, but also profitability and sustainability of range livestock operations.

AoR 152: Nathan Sayre on the Genesis and Limits of Carrying Capacity
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.
