A Beginner's Guide to Coppicing Hazel in Small Woods

Why Coppice Hazel?

Hazel is one of the great trees of the British countryside, and it has been managed by hand for thousands of years. Left alone, a hazel stool sends up dozens of stems that crowd each other and eventually shade out everything beneath. Coppicing — cutting those stems back to the base on a regular cycle — mimics what our ancestors did, and what wild grazing animals once did for free.

Two good things follow. First, light reaches the woodland floor for a few years, and the ground flora responds with wood anemone, bluebell, primrose, dog violet and wild strawberry. That flush of growth feeds fritillary butterflies, bees and moths. Second, you get poles: straight, strong, flexible hazel rods that are genuinely useful for bean poles, pea sticks, plant supports, hurdles, walking sticks and charcoal.

Because different patches are cut in different years, a coppiced wood becomes a mosaic of ages, from bare ground to ten-year-old thicket. That variety is exactly what wildlife needs.

Timing Your Cut

Cut during dormancy, between late September and early March. The sweet spot is November to February, when the sap is down and the wood is at its best for splitting and weaving. It also sits outside the main nesting season, which matters legally as well as ethically: under the Wildlife and Countryside Act 1981 it is an offence to damage or destroy the nest of any wild bird while it is in use.

• Check every stem before you cut. Blackbirds and robins nest in forks, long-tailed tits build neat balls of moss and lichen, and wrens will squeeze into almost anything.
• Work on a rotation of roughly seven to ten years for good hurdle rods, or five to seven if you want pea sticks.
• Cut one coupe — a defined block — each winter rather than the whole wood at once.
• Leave a few mature, uncut trees standing for nuts, deadwood and roosting bats.
• If you plan to cut more than five cubic metres in a calendar quarter, check whether a felling licence is needed, and check for tree preservation orders or conservation area designations before you lift a saw.

Making a Clean Cut

Sharp tools make all the difference. A bow saw deals with stems over about 3cm, loppers with the rest, and a pruning saw is handy in tight spaces. A billhook is a joy in skilled hands, but a saw is safer for a beginner.

• Cut each stem as low as you can without nicking the wood you are keeping — 5–10cm above ground is ideal.
• Use a single, clean slice. Torn or crushed ends heal slowly and invite rot.
• Angle the cut slightly downwards and away from the centre of the stool so rainwater runs off rather than pooling.
• Never leave a snag longer than your thumb. Long stumps die back and can rot down into the stool itself.
• Work around the stool from the outside in, and keep your boots off the stool — compacted, damaged wood regrows poorly.
• Take the weight of larger stems with one hand so they don't tear away as they fall.

Hazel is forgiving. Even a clumsily cut stool usually throws up new shoots the following spring, so don't agonise over perfection.

Protecting the New Growth

This is where most small coppices fail. Soft new hazel shoots are deer chocolate. Fallow and roe do real damage, and muntjac are small enough to slip through gaps and nibble a stool down to the bone. Rabbits and hares will finish off smaller stools.

• Fence the coupe if you possibly can. A 1.8m deer fence is the reliable answer, though it is an investment for a small wood.
• For individual stools, spiral guards deter rabbits and taller mesh cylinders deter deer.
• Pile the cut brash loosely over the stools you have just cut. It hides the fresh shoots from browsing animals and makes superb habitat for wrens, beetles and fungi.
• Check fences after gales and again in late winter, when hungry deer press hardest against boundaries.

Some browsing is fine — it creates variety and open patches. Complete defoliation, year after year, is not, and will kill the stool.

Using the Poles, Leaving the Brash

Sort your stems as you cut them. The straightest and longest become rods; the bendy ones become stakes and binders; the rest become firewood or deadwood habitat.

Hazel air-dries well and bends beautifully while green, so if you are making hurdles, weave them within a few days of cutting. Otherwise bundle the poles and stack them off the ground, bark on, somewhere dry and airy to season. They will last for years.

Leave some brash behind. Deadwood is one of the richest habitats in any wood — stag beetle larvae, fungi, solitary bees and a whole army of beetles depend on it. But don't leave so much that it smothers regrowth. Pile it rather than scatter it, and keep one generous habitat heap in a corner of the wood where it can rot in peace.

Wildlife to Watch on Your Walk

Once you start coppicing, you will notice the wood changing within a season. The first spring after a cut, the ground beneath the stools is warmer and brighter than anywhere else, and that is where the flowers come first.

• Spring: wood anemone, bluebell, primrose, early purple orchid, and the first bumblebees.
• Summer: pearl-bordered fritillary in western woods, speckled wood along the rides, and warblers — garden warbler, blackcap and willow warbler — singing from the regrowth.
• Autumn: hazel nuts with neat round holes mean dormice have been feeding. Look for the discarded shells on stumps and fallen logs.
• Winter: woodcock probing damp hollows, and green woodpeckers working the wood ant nests on sunny edges.

Keep your rides and extraction tracks open as part of the job — a wide, sunny ride is as valuable as any cut stool. Take a notebook and jot down what you see each visit. Over a ten-year rotation you will build a quiet, detailed record of a wood coming back to life, and that is one of the real pleasures of managing a small patch of British woodland by hand.
