Why a rotation beats a one-off cut

Coppicing is the oldest form of woodland management in Britain, and it works on a simple principle: many of our native trees will regrow from the stump if you cut them. Cut a section of wood, let the light in, and the stools throw up vigorous new shoots. Come back in eight, twelve or fifteen years and there is a crop ready to cut again.

The trouble with cutting the whole wood at once — besides the sheer amount of work — is that you lose everything in one go: the shade, the sheltered edges, the birds that nested in the older growth. A rotation avoids that. Divide the wood into blocks, known as coupes, and cut one each winter. By the time you return to the first, it has grown back. At any moment your wood holds a patchwork of ages, from freshly cut ground to near-mature poles, and it is this variety that makes a coppiced wood so rich in wildlife.

Dividing your wood into coupes

Start on paper, in the kitchen, before you start on the ground with a chainsaw. Use features that already exist — a ride, a ditch, an old boundary bank, a line of mature trees — so the coupe boundaries make sense to look at as well as to work.

• Keep coupes to a size you can actually cut, extract and market in one winter. For most small owners that means somewhere between 0.1 and 0.5 hectares.
• Cut into the prevailing wind where you can, so the new growth is sheltered by the standing crop behind it.
• Mark boundaries with a stake or a cut line that will still be visible in five years' time, when you will have forgotten exactly where you drew it.
• Leave the wet Botany — the lowest, boggiest corner — until a hard frost, or miss it out altogether and treat it as a wildlife reserve.

Getting the rotation length right

Rotation length is driven by species and by what you want from the wood. Hazel cut for hurdles, thatching spars and pea sticks is usually on an eight to ten year cycle; leave it fifteen years and the rods are too thick for weaving but excellent for firewood. Sweet chestnut does well on twelve to eighteen years. Willow and alder grown for biomass can be cut every three to five. Ash, where ash dieback allows, sits around ten to fifteen.

The arithmetic is straightforward: an eight-year rotation needs eight coupes, a twelve-year rotation needs twelve. If you have a small wood and cannot face twelve blocks, shorten the rotation rather than abandoning the idea — five or six coupes of hazel will still give you a functioning coppice.

Keep your standards, and leave the messy bits

Coppice-with-standards is the traditional pattern: most of the wood is cut on rotation, but a scattering of trees is left to grow on to full size. Oak and ash are the usual choices, at roughly ten to twenty-five per hectare. These standards give you timber, shelter and a continuous canopy, and their deep roots and hollows support species that a pure coppice never will.

Resist the urge to tidy. Leave standing deadwood, at least a few trees per hectare. Leave brash in loose heaps rather than burning it all, and stack some as a dead hedge along a boundary. Cut a scalloped edge into the ride alongside each new coupe so the sun reaches further into the wood. These small untidinesses are the difference between a wood that is merely cut and a wood that is alive.

Timing, wildlife and the paperwork

Cut between late October and early March, when the sap is down and the wood is at its driest and lightest. That window also avoids the nesting season, but it does not remove every risk.

• Bats and dormice are legally protected in the UK. Check any tree with holes, splits or dense ivy before felling, and take advice before cutting a coupe that has not been touched for decades.
• Felling licences apply in most cases where more than five cubic metres is felled in a calendar quarter. Coppicing is often exempt, particularly for small stems, but the exemptions are specific and vary between the four nations — check with your national forestry authority before you start.
• Trees with Tree Preservation Orders, and those in a conservation area, need consent even when coppicing.
• Consider leaving one coupe uncut each cycle. It costs you a year of crop and buys a great deal of habitat.

Turning a coupe into a useful crop

Sort as you cut, not afterwards. Straight rods of hazel and ash become stakes, binders, beanpoles and pea sticks. Clean chestnut poles are worth more as fencing material than as firewood. Everything crooked or knotty goes on the firewood stack, split and under cover, seasoned for at least a year.

Stack cordwood off the ground on bearers, butt ends facing the prevailing wind, and cover only the top so air can move through. Keep a notebook: the coupe number, the date, what you cut, what you sold or used. Photograph the same view each winter. After a decade, that record is worth more than any book on the subject.

Above all, keep it manageable. A coupe that defeats you in January is worse than a smaller one you finish comfortably. Take the first year slowly, cut less than you think you should, and let the rotation settle into the rhythm of your own winters. A well-worked coppice is never finished — it is simply passed on, in better heart than you found it.
