Coppice is a woodland management technique in which trees are cut close to the ground, prompting vigorous regrowth of multiple new stems from the remaining stump, called a stool. The practice exploits a natural ability many broadleaved trees have to resprout after being felled, and it has been used across Europe, Africa, and Asia for centuries to produce a renewable supply of wood without replanting. Far from being a historical curiosity, coppicing is now experiencing renewed interest for bioenergy production, biodiversity conservation, and even soil remediation on contaminated land.
How Trees Regrow After Cutting
When a tree is cut to a stump, the root system does not die. It still holds carbohydrate reserves and, critically, continues producing hormones that activate dormant buds along the stump’s surface. Research on eucalyptus seedlings found that cytokinin activity in stump and shoot tissue surged dramatically after the stem was removed, increasing anywhere from roughly five-fold to forty-fold depending on species and treatment.1Physiologia Plantarum. The role of plant hormones and carbohydrates in the growth and survival of coppiced Eucalyptus seedlings Cytokinins are produced in root tips and transported upward into the stump, where they trigger lateral buds to break and grow into new shoots. Work on a Chinese oak species confirmed this transport mechanism: cytokinin concentrations in the stump were positively correlated with resprouting ability, while cytokinin levels in the fine roots dropped, suggesting the hormone was being actively shipped out of the roots and into the aboveground tissue where it was needed.2Trees. Elevational patterns of endogenous hormones and their relation to resprouting ability of Quercus aquifolioides plants on the eastern edge of the Tibetan Plateau
The stump’s stored sugars fuel the initial burst of growth until the new leaves can photosynthesize on their own. Because the root system is already mature, the new shoots grow faster than a seedling planted from scratch would. Over time, the stool develops a characteristic ring of stems around a widening base, and these can be harvested again in cycles that vary from a few years to several decades depending on the species and intended product.
A Practice With Deep Roots in History
Coppicing is one of the oldest forms of deliberate forest management. Archival records from Meerdaal Forest in central Belgium describe a highly elaborate coppice-with-standards system already in place by the mid-1500s, complete with separate auctions for the coppice wood and the larger “standard” trees left standing above it, along with fines and punishments for theft and fraud.3iForest – Biogeosciences and Forestry. 500 years of coppice-with-standards management in Meerdaal Forest (Central Belgium) The system was sophisticated enough that it clearly had been practiced for generations before anyone thought to write down the rules.
Tree-ring evidence from central Europe has revealed what happens inside the trees that survive a coppicing event. Standard oaks left standing when the surrounding coppice was cut showed dramatic surges in ring width, averaging abnormally high growth for a full twenty-two years after each cutting event, with major growth releases documented around 1895 and 1935 corresponding to known coppicing periods.4PLoS ONE. Tree-Rings Mirror Management Legacy: Dramatic Response of Standard Oaks to Past Coppicing in Central Europe The remaining trees suddenly had access to far more light and soil moisture, and their wood records that windfall decades later.
Coppice-with-standards was the dominant form of forest management across much of western Europe for centuries. The coppice layer supplied fuel, fencing, charcoal, and tool handles on short rotations, while the scattered standards grew into larger timber over longer periods. The system declined sharply in the twentieth century as coal and then petroleum replaced wood as a primary fuel, but its legacy persists in the structure of many European forests today.
Which Trees Coppice Well
Not every species regrows reliably after cutting. Broadleaved hardwoods dominate the list of strong coppicers. Oaks, hazels, willows, poplars, sweet chestnut, hornbeam, and many eucalyptus species are well-known for vigorous resprouting. Conifers, with a few exceptions, generally do not coppice because they lack the dormant buds near the base of the trunk that broadleaves rely on.
Even among broadleaves, there is wide variation. A trial in New Zealand testing multiple species for short-rotation biomass production found that most eucalyptus species survived coppicing well, with several showing no tree mortality even after a second harvest, while E. nitens stood out as a poor performer with survival below fifty percent.5Biomass and Bioenergy. Short rotation coppice tree species selection for woody biomass production in New Zealand The best performers in that trial actually yielded more biomass per year during the coppice rotation than they had during their initial growth as single stems, confirming the advantage that an established root system provides.
In African miombo woodlands, resprouting rates varied from zero to one hundred percent depending on species, stump height, and size at the time of cutting. Across thirty harvested species in a forest reserve, about eighty-three percent resprouted, while in more frequently disturbed public lands the figure was ninety percent.6Forest Ecology and Management. Regeneration by coppicing (resprouting) of miombo (African savanna) trees in relation to land use Stump height and tree size at cutting influenced how many new shoots appeared, with some species like Pterocarpus angolensis averaging over seven shoots per stump in frequently harvested areas.
Why Coppiced Woodlands Support So Many Species
A coppiced woodland is not a static environment. Each time the stools are cut, the canopy opens and light floods the forest floor. Wildflowers, grasses, and shrubs respond within a season or two. As the new stems grow and the canopy closes again over the following years, the understorey shifts toward shade-tolerant species. When different coupes within a woodland are cut on a staggered rotation, the result is a mosaic of patches at every stage of regrowth, from freshly cut to nearly mature. That structural variety supports a range of species that a uniform closed-canopy forest cannot.
Research on butterflies in European coppice woodlands found that these forests are hotspots for butterfly diversity and serve as refuges for threatened species. Every successional stage had characteristic butterfly species associated with it, though the early and mid-successional stages carried the highest conservation priority.7Biological Conservation. Effects of coppicing on butterfly communities of woodlands The same pattern held for moths and wood-dwelling beetles. A coppiced woodland functions as a slowly shifting patchwork habitat rather than a single uniform block, and that heterogeneity is the key to its ecological value.
What Happens When Coppicing Stops
The flip side of coppicing’s biodiversity benefits is what occurs when the practice is abandoned, as it was across much of Europe during the twentieth century. Without periodic cutting, the canopy closes and stays closed. Light-demanding wildflowers, grasses, and early-successional shrubs lose their habitat and gradually disappear.
Surveys of two Czech woodlands that had once been actively coppiced revealed stark losses. In one wood, average species richness per plot dropped from about twenty-eight to nineteen species. Forty percent of the species recorded in earlier surveys were absent from later ones, compared to just four percent that were new arrivals.8PubMed Central. Coppice abandonment and its implications for species diversity in forest vegetation The forests shifted from species-rich oak-hornbeam communities toward poorer assemblages dominated by shade-tolerant trees like lime, ash, and maple. Red-listed species declined substantially.
A separate study across abandoned coppice forests in Europe characterized these losses as ecologically non-random extinctions. Light-demanding species with persistent seed banks were the most likely to vanish, while shade-adapted species with large leaves increased. The result was not just fewer species but a more homogeneous understorey with lower variation from one patch to the next.9PubMed Central. Non-random extinctions dominate plant community changes in abandoned coppices The species that remained were essentially a nested subset of the original flora, meaning the community was not being replaced by a different one but was simply being whittled down.
This has made coppice restoration a conservation priority in parts of Europe. Resuming traditional rotational cutting is one of the few management interventions that can recreate the open, light-rich conditions these threatened plant and insect communities need.
Effects on Soil and Nutrients
A reasonable concern about repeated harvesting on short rotations is whether it drains the soil of nutrients. The answer turns out to be more nuanced than you might expect. A study comparing coppice woods and high forests in Germany’s Siegerland region found that the high forests contained about four times as much aboveground biomass and stored two to three times more calcium, potassium, magnesium, and nitrogen in that biomass. Their forest floors were thicker and held six times more organic matter.10Basic and Applied Ecology. Effects of coppicing in temperate deciduous forests on ecosystem nutrient pools and soil fertility
Yet the mineral topsoil told a different story. The coppice woods had higher pH, substantially larger pools of plant-available calcium, potassium, and magnesium, and roughly a quarter more total nitrogen in the top twenty centimeters. The researchers attributed this to several factors working together: ash from historical biomass burning after cutting, nitrogen fixation by broom that colonizes cleared areas, warmer soil temperatures under the more open canopy, and the presence of leaf-litter-rich species in the coppice stands. Frequent disturbance apparently accelerates nutrient cycling fast enough to keep the topsoil well-supplied even as the total ecosystem nutrient capital is lower than in an undisturbed high forest.
That said, there are limits. Work on aged oak coppice forests with acidic, nutrient-poor soils warned that resuming intensive harvesting on such sites could lead to serious nutrient depletion, and recommended restricting removal to only the larger-diameter wood components.11Forest Ecology and Management. Effects of different harvesting intensities on the macro nutrient pools in aged oak coppice forests On richer soils, the system is more forgiving. On poor, acidic ground, harvesting intensity matters a great deal.
Short Rotation Coppice for Energy
The modern incarnation of coppice that attracts the most commercial attention is short rotation coppice, usually abbreviated SRC. This involves planting fast-growing willows or poplars at high density, cutting them on cycles of two to five years, and chipping the harvested stems for use as biomass fuel. It is essentially industrial-scale coppicing.
A large forty-nine-site trial network in the UK reported mean modelled yields for poplar and willow SRC ranging between about five and eleven oven-dry tonnes per hectare per year. Willow generally outperformed poplar in those trials, partly because the older poplar varieties tested were susceptible to rust disease and tended to produce a single dominant stem rather than the multi-stem growth that maximizes biomass yield.12PubMed. Yield and spatial supply of bioenergy poplar and willow short-rotation coppice in the UK However, trials in southern Quebec found that certain poplar hybrids outperformed the willow clones tested there, a reminder that clone selection and local growing conditions matter as much as species choice.13Biomass and Bioenergy. Field performance and biomass production of 12 willow and poplar clones in short-rotation coppice in southern Quebec (Canada)
Modelling for Germany identified roughly eighteen percent of cropland and over half of grassland as highly suitable for SRC plantations, with those sites averaging more than fourteen dry tonnes per hectare per year under favorable water and temperature conditions.14GCB Bioenergy. Land availability and potential biomass production with poplar and willow short rotation coppices in Germany The practical constraint is rarely land availability but rather whether the economics work for the farmer.
The Economics of Growing Wood on Short Cycles
A review of thirty-seven economic studies on SRC systems found that just under half reported SRC as economically viable compared to a reference system, about one in five found it disadvantageous, and the rest produced mixed results depending on assumptions.15Renewable and Sustainable Energy Reviews. Economic evaluation of short rotation coppice systems for energy from biomass—A review Profitability was most sensitive to two factors: the price a grower could get for the biomass and the yield actually achieved. Site-specific yield data was frequently lacking, which made many projections unreliable. Among costs, land rent, harvesting, chipping, and establishment consistently dominated, so improvements in any of those areas can tilt the balance.
In Brazil’s charcoal sector, an analysis of different forestry scenarios found that a coppicing approach produced the highest financial returns, with an internal rate of return above thirty percent and the lowest average production cost per cubic meter compared to replanting or other strategies.16ScienceDirect. Strategic financial decision-making for forest bioenergy: investment scenarios and policy insights for charcoal enterprises in Brazil The advantage comes from eliminating replanting costs: a coppiced stand regenerates itself, saving both the expense of new seedlings and the several years of slow early growth that a freshly planted stand requires.
Coppice and Water
Trees use water, and coppiced stands are no exception. A watershed study in India’s Nilgiri hills tracked the hydrological effects of bluegum eucalyptus plantations through their first planting and then a coppice regrowth cycle. During the coppice rotation, mean annual total runoff fell by about twenty-five percent and base flow by twenty-seven percent compared to the natural grassland that had occupied the site before, both larger reductions than those observed during the original planting rotation.17Journal of Hydrology. Hydrological behaviour of first generation coppiced bluegum plantations in the Nilgiri sub-watersheds The difference was attributed to the coppiced trees having a fully developed deep root system from day one, allowing them to access soil moisture more aggressively from the start and produce over forty percent more biomass than the first rotation.
This is worth bearing in mind where SRC or coppiced plantations are established in water-sensitive catchments. The same root advantage that makes coppice economically attractive also means the trees can draw down local water supplies more effectively than a new planting. In dry regions or where downstream water users depend on runoff, the trade-off deserves careful consideration.
Coppice Under Drought
A separate question is whether coppiced trees handle drought differently from trees grown as single stems. A study comparing coppice and high-forest eucalyptus stands on deep soils found no significant differences in drought resistance between the two management types. Variability among genetic clones explained far more of the differences in drought tolerance traits than whether the tree had been coppiced or grown from seed.18Tree Physiology. Coppice and high forest Eucalyptus stands show similar drought resistance on deep soils In other words, choosing a drought-tolerant variety matters more than choosing between coppice and conventional planting.
Thinning, which is sometimes applied within coppice stands to reduce competition among stems, does appear to help. A fifteen-year rainfall exclusion experiment in a holm oak coppice showed that stem growth was strongly affected by thinning but was not significantly reduced by the artificial drought treatment. Trees that had been given more space by removing competing stems grew better even under reduced rainfall, and the largest stems benefited the most from competition release.19Forest Ecology and Management. Drought mitigation by thinning: Benefits from the stem to the stand along 15 years of experimental rainfall exclusion in a holm oak coppice For land managers worried about future droughts, thinning an overstocked coppice stand may be a more effective intervention than avoiding coppice management altogether.
Cleaning Up Contaminated Soil
One of the more inventive modern applications of SRC is phytoremediation: using the trees themselves to gradually extract heavy metals from polluted soil. Willows and poplars are already the go-to species for SRC, and they also happen to accumulate metals like cadmium and zinc in their tissues. A Belgian study on acid, sandy, metal-contaminated farmland tested whether SRC could serve a dual purpose: producing biomass for energy while slowly cleaning the soil. The researchers found that willows were considerably more efficient at extracting metals than poplars, though even with willows it would take at least thirty-six years to bring cadmium levels below legal thresholds.20PubMed. Short rotation coppice culture of willows and poplars as energy crops on metal contaminated agricultural soils
That timeline sounds discouraging until you consider the alternatives. Conventional soil remediation on agricultural land is expensive and destructive, often involving excavation or chemical treatment. SRC phytoremediation is slow but provides income from biomass sales in the meantime, keeps the land in productive use, and does not disrupt the soil structure. For farmers stuck with marginally contaminated fields that are not polluted enough to justify the cost of conventional cleanup but too polluted for food crops, it can be the most practical option available.
Ancient Stools and Water-Filled Hollows
A coppice stool that has been cut and regrown many times over centuries develops a distinctive form. The base widens and sometimes splits into a ring-shaped structure as old heartwood rots away while the living cambium continues growing outward. Some ancient stools are enormous, several meters across, and can be older than any individual tree in the surrounding forest, even though no single stem on them is particularly old. Dating these stools precisely is difficult because the original central wood is long gone, but some are estimated to be many centuries old based on historical records of continuous management.
A field survey of twenty important coppice woodland sites recorded one hundred thirty-five ancient coppice stools across thirteen tree species, along with eighty water-filled tree hollows, known as dendrothelms, in nine species.21Journal of Landscape Ecology. Tree shape and form in ancient coppice woodlands These dendrothelms form in the decaying heartwood of old stools and function as miniature aquatic habitats, hosting mosquito larvae, small crustaceans, and other invertebrates. They are yet another way that coppiced woodlands create microhabitat diversity that a plantation of uniformly aged single-stem trees never would.
Cultural Dimensions Beyond European Forestry
Coppicing is often framed as a European tradition, but the underlying principle of cutting plants to encourage vigorous, straight regrowth has been practiced by Indigenous peoples around the world. In California, Native basketweavers have long tended their plant materials through techniques that overlap with coppicing, cutting willow, redbud, and other basket plants to produce the straight, pest-free, renewed growth that is suitable for weaving.22Ecology and Society. Getting back to that point of balance: Indigenous environmental justice and the California Indian Basketweavers’ Association This management is not a simplified version of European coppice. It reflects a distinct knowledge system developed over millennia, one that integrates fire, selective harvesting, and ongoing observation of individual plant responses in ways that European silviculture has only recently begun to appreciate. Access to the lands where these plants grow remains a live political issue, and the ongoing work of organizations like the California Indian Basketweavers’ Association connects coppice-like land management directly to questions of Indigenous sovereignty and environmental justice.
