Mark Shepard farms 106 acres in southwestern Wisconsin using a system he calls STUN: Sheer Total Utter Neglect — applied selectively to organisms he wants to evolve toward local resilience while systematically tending the perennial polyculture that has replaced what was once a conventional row-crop farm. Restoration Agriculture is both a farming manual and a philosophical manifesto: the most thorough available argument for replacing annual grain crops with perennial food-producing systems.
The Core Argument
Shepard begins with a simple observation: before European settlement, the upper Midwest was covered with oak savannas, mixed forests, and tall-grass prairies — perennial ecosystems that built topsoil, sequestered carbon, and supported enormous biodiversity over thousands of years. The annual grain farming that replaced them does the opposite: it depletes topsoil, releases carbon, and requires massive external inputs to remain productive. Each year of conventional cropping leaves the land poorer.
The solution he proposes is to replace annual grain farming with perennial polycultures that mimic the structure and function of the native ecosystems they displaced. At New Forest Farm, the model ecosystem is the oak savanna: overstory nut trees (chestnuts, hazelnuts, oaks) above perennial fruits (apples, pears) above perennial vegetables and fodder (asparagus, comfrey) above managed pasture for cattle, pigs, and sheep. The system produces food, timber, fodder, and ecosystem services simultaneously — and requires progressively less human intervention as the perennial systems establish themselves.
What This Looks Like in Practice
The farm chapters are compelling: Shepard describes specific species combinations, spacing decisions, grazing rotations, and the economics of perennial systems in a way that makes the model tangible. He is honest about the limitations: establishing a perennial polyculture requires significant upfront investment, produces less in the first several years than annual alternatives, and requires patience and willingness to accept complexity.
The payoff, as the system matures, is a farm that feeds itself — building fertility, managing pests biologically, and producing diverse outputs that spread economic risk across the calendar year.
The land wants to be perennial. Every time we disturb the soil to plant an annual crop, we are interrupting a succession that is trying to become something more complex and more resilient.

6 Key Ideas From This Book
Domesticated annual grain crops — wheat, corn, soy, rice — are the foundation of the global food system but are profoundly abnormal from an ecological perspective. Bare soil, monoculture, and annual disturbance are signs of catastrophe in natural systems. We have built civilisation on a mode of production that mimics ecological disaster.
Perennial plant communities — grass, shrubs, trees — build topsoil through root growth, organic matter addition, and the activity of the soil biology they support. Annual cropping, with its tillage and bare-soil periods, does the opposite. Transitioning to perennial systems is one of the most effective available tools for reversing topsoil depletion.
A farm producing nuts, fruits, vegetables, meat, timber, and biomass from the same acres is insulated from the price collapse of any single commodity in a way that a corn-soy rotation is not. Diversity of outputs is a risk management strategy as well as an ecological strategy.
Shepard's design methodology starts with the question: what grew here before? The native ecosystem, adapted to local climate and soil over thousands of years, is the most productive and resilient system possible in that location. Restoration agriculture tries to produce food within that ecological framework rather than replacing it.
Cattle, pigs, and sheep in Shepard's system are not just outputs — they are managers. Pigs root up competing vegetation; cattle graze the understory; chickens harvest insects. Each animal species is doing work that would otherwise require human labour or equipment, and doing it in ways that build the system rather than depleting it.
Shepard documents the economics of perennial system establishment honestly: lower production in years one through seven, increasing productivity as trees and shrubs establish, and dramatically higher productivity per input dollar once the system matures. The transition requires patience and access to capital that annual crop economics doesn't require.
Any Weaknesses?
Shepard is an evangelist for his system, and the book occasionally overpromises. The transition from row-crop farming to perennial polyculture is genuinely difficult, and Shepard’s timeline for the economic transition is optimistic for most farmers dealing with existing debt and market constraints.
The book is also heavily focused on the upper Midwest climate and ecology. Readers in different climates will need to translate the specific species and spacing recommendations significantly.
Farmers considering the transition to perennial systems, land managers interested in agroforestry, and anyone who wants the most thoroughly worked-out alternative to annual grain agriculture available in popular form.
Edible Forest Gardens by Dave Jacke for the permaculture design methodology that underlies this approach, and Dirt to Soil by Gabe Brown for the soil health perspective.
Investment fund managers interested in farmland. The economics of perennial polyculture — initially capital-intensive, ultimately lower-cost and more resilient — have implications for how farmland should be valued and managed at scale.
Shepard makes large claims about the potential of perennial systems to address soil degradation, climate change, and food security simultaneously. These claims are directionally correct but the implementation at civilisational scale remains undemonstrated. Read with appropriate scientific caution.
