Trees as Tools — Grazing with Purpose with Austin Unruh

In this episode of The Stockman Grassfarmer Podcast, we sit down with Austin Unruh, founder of Trees for Graziers and author of The Grazier’s Guide to Trees, to explore how trees can become one of the most powerful tools on a livestock operation. Austin shares how he moved from suburban roots into agroforestry, eventually developing practical, scalable systems for planting and protecting trees in active pasture. From innovative electric fencing designs to species selection for winter feed and summer drought resilience, this conversation reframes trees as more than shade — but as forage banks, livestock nutrition tools, and long-term economic assets. 🔑 Key Points Covered: Planting Trees in Active PastureAustin explains the six-foot tree shelter system and the “overpass” electric fencing method that protects young trees while keeping paddock flexibility intact. Trees as Seasonal Feed SourcesHoney locust pods for winter sugar-rich feed and tree fodder for summer protein offer ways to reduce purchased feed costs during critical times. Species-Specific BenefitsGoats, sheep, cattle, pigs, and even horses can benefit from different tree crops — from fodder leaves to mast like acorns and chestnuts. Acorn-Finished Pork & Historical ContextAmerica once produced vast quantities of mast-fed pork. Austin explains how diversified tree systems today could rival Spain’s dehesa model. Drought Resilience Through PollardingManaged tree fodder systems act like standing hay reserves — perennial feed banks available when pastures fail. Silvopasture DevelopmentWhether planting into open pasture or thinning degraded woods, intentional tree integration improves shade distribution, forage production, and long-term land value. Tree Density & Long-Term MaintenanceLessons learned on planting density, pruning for high canopies, and balancing fast-growing nurse trees with long-term mast species. The Grazier’s Guide to TreesAustin shares insights behind his book and the upcoming updated edition published through Acres U.S.A. 🌱 Actionable Insights: Use trees strategically to reduce feed costs during summer slump and winter dormancy. Protect young trees with insulated shelters and overhead electric systems to maintain grazing flexibility. Consider mast-producing species like honey locust, oak, chestnut, persimmon, and mulberry for diversified livestock nutrition. Manage canopy height to distribute shade movement and prevent livestock concentration damage. View tree fodder as a long-term drought insurance policy — a living feed reserve that grows each year. 📌 For more insights and resources, be sure to visit us here for our latest specials and exclusive offers 👉 Tune in with your favorite podcast app to The Stockman Grassfarmer Podcast and discover practical grazing innovations that blend ecology, livestock performance, and long-term profitability.
