Most gardeners think of succession planting as a row of lettuce, then a row of carrots, then a row of kale. Ernst Götsch thinks about succession differently, on a scale of decades, in stacked layers, with deliberate pruning that triggers hormone responses in the soil. His farm in Bahia turned 480 hectares (about 1,186 acres) of degraded cattle pasture into a working rainforest that produces premium cacao alongside fruit, nuts, timber and 14 restored water springs. That work has a name: syntropic agriculture. And the core engine inside it is a particular way of thinking about succession that homestead gardeners can adapt directly.
This guide translates the four syntropic consortia and four light strata into a working temperate-climate planting plan, then explains the pruning that makes the whole thing run. If you have come from our introduction to syntropic agriculture and want to know how to actually plant one, this is the working blueprint.
Conventional succession planting is sequential: harvest one crop, plant the next. Syntropic succession is simultaneous, stacked and intentional. You plant species from four different life-cycle groups (called consortia) and four different light positions (called strata) all at once, in the same bed. As fast-cycling pioneers complete their job and die back, the medium-life species are already established. As those mature and decline, the long-life climax trees are already in the canopy. The plot is designed to change, and pruning is what drives that change forward.
Ernst Götsch developed this framework in the 1980s after moving from Switzerland to a 480-hectare farm in southern Bahia that had been logged, burned and overgrazed. Wikipedia documents his background as "a Swiss farmer and researcher working mostly in Brazil" who advocates a system of climate- and biodiversity-friendly farming. The Global Earth Repair Foundation records that Götsch has "converted over 1,200 acres of degraded land in Brazil into a productive rainforest that produces premium cacao, among other things." The framework that did it is now taught worldwide and is being adapted to temperate climates by practitioners like Mark Shepard in Wisconsin and Ben Falk in Vermont.
Key Takeaway
Syntropic succession is not "plant a crop, then plant another crop." It is planting four time horizons in the same bed at once (0 to 3 years, 2 to 12 years, 12 to 40 years, 40 to 150 years), in four light strata simultaneously (emergent, high, medium, low), then driving the system forward with deliberate pruning. Done right, total system yields can run multiple times higher than monoculture on the same land.
The first axis of syntropic succession is time. Mountain Time Farm documents how syntropic systems organize plants by life cycle and role in ecological succession, from pioneer species that prepare the ground to climax species that dominate the mature canopy.
| Consortium | Time Horizon | Ecological Role | Example Species |
| Placenta | 0 to 3 years | Fast-growing pioneers, rapid soil cover, biomass and nitrogen fixation, "hunger-gap" food | Corn, beans, sunflower, brassicas, lettuce, radish, pigeon pea, banana, sunchokes, comfrey |
| Secondary I | 2 to 12 years | Transition to intermediate forest, structural biomass, partial canopy | Inga, gliricidia, mulberry, black locust, hazelnut, serviceberry, fast-cycle bananas |
| Secondary II | 12 to 40 years | Primary food production tier, medium-life fruit and nut | Cacao, coffee, citrus, avocado, apple, pear, plum, cherry, jaboticaba, elderberry |
| Climax (Secondary III) | 40 to 150+ years | Long-lived canopy, emergent layer, timber and nut | Walnut, pecan, chestnut, hickory, oak, Brazil nut, mahogany |

Every bed contains all four. The Placenta species die back or get coppiced in years 1 to 3, having shaded the soil, fixed nitrogen and produced a year of hunger-gap food while the Secondary I species establish underneath them. The Secondary I species produce their main yield in years 3 to 10 while sheltering the Secondary II canopy that takes over in years 10 to 30. By the time the Secondary II species peak and decline, the climax species have entered their productive timber and nut phase.
Why This Works: Stacking Succession in Time
A monoculture orchard is a single life-cycle stage. By year 30 the apple block is in decline, and you have nothing else producing. A syntropic bed planted in year zero has four producing layers by year 10 and four different producing layers by year 30. The land never empties. The system never resets to zero. That is why a peer-reviewed 15-year Bolivia trial in Agronomy for Sustainable Development found agroforestry cacao at roughly 75% of monoculture cacao yield, but with 22 additional crops harvested from the same plot, putting total system yield up to 6.9 times higher than the monoculture.
The second axis is light. Mountain Time Farm documents that "syntropic systems organize plants into emergent, high, medium, and low strata, ensuring efficient use of space and sunlight." Each stratum is defined by light requirement, not by mature height. This is one of the most common beginner mistakes: a beginner allocates plants by ruler instead of by ecophysiology.
| Stratum | Light Requirement | Canopy Position | Example Species |
| Emergent | Full sun, no shade tolerance | Above all others, future timber canopy | Black walnut, pecan, oak, eucalyptus |
| High | Full sun, tolerates light shade | Primary fruit-producing layer | Apple, pear, stone fruits, smaller nuts |
| Medium | Mix of sun and shade, fails in either extreme | Mid-canopy | Elderberry, hazelnut, pawpaw, coffee, cacao |
| Low | Shade tolerant, filtered sun | Understory and herbaceous layer | Ginger, turmeric, woodland berries, mint, comfrey |

The unbreakable design rule: every stratum should contain representatives from all four consortia simultaneously. A working plot stacks succession (time) and stratification (space) in one design. So your emergent stratum has a Placenta species (sunflower towering above young seedlings) plus a Secondary I species (black locust) plus a Secondary II species (a young walnut, decades from its emergent role) plus your eventual Climax tree.
The tropical species list from Götsch's Bahia farm does not translate one-for-one into a backyard in Zone 5. What translates is the framework. Identify temperate-zone species with equivalent ecological functions and substitute them into the same four-consortia, four-strata grid. Propagate Ag's cold-climate syntropic agroforestry guide walks through that translation in detail.
| Consortium (Time) | Temperate Homestead Species | Function |
| Placenta (0 to 3 yr) | Bush beans, peas, lettuce, radish, brassicas, sunflower, comfrey, sunchokes, Siberian pea shrub, daikon, mint, oregano | Fast biomass, nitrogen fixation, hunger-gap food, weed suppression |
| Secondary I (2 to 12 yr) | Mulberry, black locust, hazelnut, serviceberry, autumn olive, raspberry and blackberry canes, currants, gooseberry, alder, willow, hybrid poplar (coppice) | Mid-life biomass and first perennial yields, structural shade for Secondary II |
| Secondary II (12 to 40 yr) | Apple, pear, plum, cherry, peach, persimmon, pawpaw, elderberry, juneberry, jujube | Main food production tier |
| Climax (40+ yr) | Walnut, chestnut, pecan (Zone 6+), hickory, oak, sugar maple | Long-term canopy, nuts, timber, biological insurance |

A 30-foot by 10-foot homestead bed might look like this. At the back: one chestnut or walnut sapling (Climax, emergent stratum). 6 feet in front: three apple or pear trees on semi-dwarf rootstock spaced 8 feet apart (Secondary II, high stratum). Between and in front of them: mulberry, black locust and hazelnut at 4-foot spacing (Secondary I, high to medium stratum). Filling every gap: rows of bush beans, sunflower, sunchokes and comfrey (Placenta, all four strata). Ground layer: white clover living mulch, plus mint, oregano, woodland strawberries (Placenta and Secondary I, low stratum). On day one, that bed looks like a vegetable garden with some twigs in it. By year five, it is a young food forest.

Open the Beginner's GuideThis is the part most beginners get wrong. Syntropic succession is not a "plant it and walk away" system. The whole framework runs on aggressive, regular pruning. Götsch's position, quoted by Agenda Gotsch, is direct: "Pruning is the fuel of transformations and the key to the acceleration of natural succession." If you do not prune, you do not have a syntropic system. You have an overcrowded mess.
Pruning serves three functions at once. First, it opens light to the next stratum below. Second, the cut biomass becomes mulch and slow-release fertility on the bed. Third, and this is the part conventional horticulture ignores, the pruning itself triggers a hormonal cascade in the remaining plant. Agenda Gotsch documents: "The pruned plants invest in new growth in both the aerial part and their roots, and the growth information changes the biochemical composition of enzymes and hormones in the roots, which indirectly favors greater retention of water and nutrients."
The intensity scales with the consortium. Placenta species get 50 to 70% of their biomass removed two to four times a year. Secondary I species get 20 to 40% removed once or twice a year. Secondary II species get a light 10 to 20% formative prune per year. Climax trees get only minor formative pruning while young. Our dedicated guide on pruning in syntropic agriculture walks through the calendar for each layer.
Common Mistake to Avoid
Removing only 10 to 15% of biomass at a prune feels like real work but fails to trigger the regrowth hormones Götsch documented. Syntropic pruning is offensive, not defensive. On Placenta species like comfrey, sunchokes, mulberry and black locust, aim for 50 to 70% removal. The plant will respond with vigorous new growth and root activity. Light pruning gives you a stunted plant and weak mulch flow.
| Mistake | What to Do Instead |
| The "hungry system": too many fruit trees, too few biomass species | Dedicate 30 to 50% of the plot to sacrificial biomass species (comfrey, sunchokes, sunflower, black locust, mulberry, willow). They are the engine. (The Most Common Mistake in Syntropic Farming, YouTube.) |
| Insufficient pruning | Aim for 50 to 70% biomass removal on Placenta species, two to four times per year. Light pruning fails to trigger the regrowth response. (Agenda Gotsch on pruning.) |
| Allocating strata by mature height | Allocate by ecophysiology. A 20-meter (66 foot) shade-tolerant tree may sit in the low stratum; a 3-meter (10 foot) sun-demanding shrub may sit in the high stratum. (ECHO Community Syntropic Farming forum.) |
| Copy-pasting tropical species lists into temperate beds | Identify temperate species with equivalent ecological functions (mulberry, black locust, hazelnut, comfrey, sunchokes) and substitute them into the same framework. (Propagate Ag cold climate guide.) |
| Treating the system as static | Placenta species are designed to be removed or coppiced as Secondary species mature. Do not preserve them out of sentiment. (Mountain Time Farm.) |

Götsch's farm in southern Bahia, called Olhos d'Agua (Eyes of Water), was reforested from cattle pasture starting in 1982. The Organic Consumers Association documents that the family moved to the 480-hectare property and converted it into the flagship demonstration of syntropic agroforestry, generating premium cacao alongside fruit, nuts, timber and ecosystem services. The FAO Family Farming Knowledge Platform records that the project also recovered 14 water springs and developed a self-sustaining local microclimate on the farm. The same FAO entry points to Götsch's 2015 documentary, Life in Syntropy, made for the COP21 climate conference in Paris, which is the most accessible visual record of what the mature system actually looks like.
The pattern repeats at smaller scales in temperate climates. Mark Shepard's New Forest Farm, a 106-acre former corn farm in the Driftless Area of Wisconsin, is described as "one of the country's most ambitious large-scale conversions of former degraded corn farm into a perennial agricultural ecosystem," built around hazelnuts, chestnuts, walnuts and apples. Ben Falk's Whole Systems Design in Vermont has been "designing, building, and consulting on regenerative and resilient land/living systems in Vermont and around the world for over 20 years" on a ten-acre cold-climate farm. Neither is identical to Götsch's tropical system, but both share the same four-consortia, four-strata succession logic working farms that prove the framework holds.
The peer-reviewed evidence base is now catching up to the practice. A 2025 review in The Lancet Planetary Health concludes that syntropic farming systems show favourable performance for "carbon storage, soil fertility, water cycling, climate resilience, and plant health" across widely varying cropping systems and environments.
Syntropic succession is the planting of four life-cycle groups (Placenta 0 to 3 years, Secondary I 2 to 12 years, Secondary II 12 to 40 years, Climax 40 to 150 years) and four light strata (emergent, high, medium, low) simultaneously in the same bed. As fast-cycling pioneers die back, medium-life species are already established underneath, and climax trees take over the canopy decades later. The framework was developed by Swiss-Brazilian farmer Ernst Götsch on a 480-hectare farm in southern Bahia starting in 1982.
Both stack plants in layers, but syntropic systems add two things permaculture food forests often skip. First, an explicit time-axis: every bed contains all four consortia from day one, so the bed never empties. Second, deliberate aggressive pruning of pioneer species, which Götsch documented as the trigger for hormone responses that drive the soil microbiome and water cycling. A classic food forest tends to be a static seven-layer design; a syntropic system is a planned succession through four time horizons.
Yes. The species list changes but the framework does not. Mark Shepard's 106-acre New Forest Farm in Wisconsin and Ben Falk's ten-acre Whole Systems Design farm in Vermont both apply syntropic succession to temperate climates. The placenta layer uses bush beans, sunflower, sunchokes and comfrey. Secondary I uses mulberry, black locust, hazelnut and serviceberry. Secondary II uses apple, pear, plum and pawpaw. Climax uses walnut, chestnut and oak.
Placenta species (comfrey, sunchokes, sunflower, black locust, mulberry, willow) get 50 to 70% biomass removed two to four times per year. Secondary I species get 20 to 40% removed once or twice a year. Secondary II fruit trees get a light 10 to 20% formative prune annually. Climax timber trees get only minor formative pruning while young. Light pruning (under 30%) does not trigger the regrowth-hormone response Götsch documented and leaves the bed stunted.
The Placenta consortium produces food in months: bush beans, lettuce, radish, sunflower seeds, sunchokes. The Secondary I layer (mulberry, serviceberry, hazelnut, raspberry, currants) produces in years 2 to 4. The Secondary II fruit tree layer hits full production in years 5 to 10. The Climax nut and timber layer takes 15 to 40 years. So you eat from the bed in year one, eat well from year five, and eat from the climax canopy starting around year ten to fifteen.
Ernst Götsch is a Swiss-Brazilian farmer and researcher born in Raperswilen, Switzerland, in 1948. He moved to Brazil in the early 1980s and acquired Olhos d'Agua, a 480-hectare farm in southern Bahia, which he reforested using a system he later named syntropic agriculture. The farm has restored 14 water springs and produces premium cacao alongside fruit, nuts and timber. His 2015 documentary, Life in Syntropy, was made for the COP21 climate conference in Paris.
Designing a "hungry system": planting many target species (fruit and nut trees) and too few biomass species (comfrey, sunchokes, sunflower, mulberry, black locust). The biomass species are the engine of the system. Dedicate 30 to 50% of the plot to them, and prune them aggressively (50 to 70% biomass removal) two to four times a year. The cut biomass becomes the fertility flow for the target species.
