Hurdles: introduction

What are hurdles?

Hurdles are woven wooden fence panels made from coppiced hazel or willow. They were traditionally used as moveable agricultural fencing, especially for sheep on chalk downlands, and much of our surviving workable hazel coppice is situated close to those downlands – in Dorset, Hampshire, Surrey and Sussex, although there are pockets all over the country. Young trees are cut back to ground level in a regular cycle, the length of which depends on the species. Many shoots will reappear from one stump, providing a lot of new material in a relatively short time.

hurdles are more often used for garden fencing nowadays

Continuous weave fencing is constructed in the same way as hurdles, but as it is woven in situ it forms a more permanent barrier, and can also follow the contours and slope.

Coppicing has a long history. Archaeological digs have uncovered the remains of hurdles on the Somerset levels from neolithic times. They were used as walkways through the wetlands rather than fencing, and were preserved because they were pressed into the peaty, wet soil. The primary product of coppicing was fuel. Before oil, gas or electricity, everyone burned wood to keep warm. Woods were coppiced for thousands of years, producing material for basketry and wattles as well as firewood and hurdles.

Hurdles have traditionally had two main uses for the sheep farmer. Firstly, they were used to make lambing pens. Four hurdles make a quick, easy pen to keep a ewe and her lambs out of the worst of the weather, and to keep them close together so that they can bond properly. Secondly, they were used to make larger pens to contain sheep at night on arable land. Their dung fertilised the arable fields, and they were released back to the downs to graze the next day. Sheep hurdles were often made with a ’twilling hole’ in the middle so that the shepherd could carry four or five hurdles over his shoulder with his crook through the hole.

The old agricultural uses have now gone, and farmers don’t tend to buy or make them these days, but use metal hurdles instead. Traditional hurdles are still used by some smallholders, but mostly they’re used in gardens as windbreaks or fencing, as people tend to like their rustic appearance.

Willow has historically been coppiced on a one-year rotation, producing round rods for basketmaking, and so willow for hurdles is a product of that form of management, and therefore round. Hazel is grown on 6-8 year coppice rotation, and so the resulting, larger rods are cleft in two down their length to produce the material for hazel hurdles.

What are the benefits of hurdles?

Hurdles offer an alternative to the classic larch-lap fence panels found in garden centres, which aren’t wind-permeable, and so the wind can eddy over the top and damage plants behind them. Hurdles are wind-permeable – the wind filters through the gaps with no eddies created, making them very effective wind breaks.

Hurdle-making is a great skill to learn, and like most of Lowimpact.org’s topics, can form the basis of a small, sustainable business using locally-produced, natural materials. But you can’t make hurdles without coppicing, and it’s the production of the raw materials for hurdles via coppicing where we find most environmental benefits.

Coppicing is the ultimate form of sustainable woodland management – especially coppice with standards, where coppiced trees are mixed with mature specimens. Ideally, trees within a coppice are harvested in rotation, so that different trees will be harvested each year. This provides a regular supply of material and means that there will be lots of trees at different points in their rotation, meaning more different habitats and greater biodiversity. The opening up of the woodland allows in light, and with it a greater variety of flowers, butterflies and birds.

What can I do?

If you’re making your own hurdles, your biggest problem is likely to be sourcing the raw materials – often a stumbling block with old crafts. Most coppice in the UK is in a band along the south of England, so it will be much easier to get coppiced rods there. You could contact your local Wildlife Trust or other conservation organisation to see if they do any coppicing for habitat management. You can also buy hazel or willow products from the Coppice Products website. If you have land, you could establish your own coppice. Generally, coppicing will only spread if it’s economically sustainable – which is difficult, as it means lots of work for not a great deal of return. However, there is more demand for coppice products these days than there are coppices to provide them, so the opportunity is there if you’re committed to woodland work as a way of life.

If you decide that you want to make your own hurdles the way to start is to attend a course. It’s physically hard work, so it’s great exercise (the part that most course participants find hardest is putting the ‘twist’ in, which is a tricky technique and physically demanding). There are three key things to learn:

  1. how to split hazel rods – commonly done with a hook-nosed billhook
  2. how to put the twist in, so that the rod can turn back on itself at the edge of the hurdle, which prevents it from falling apart
  3. how to start off and finish the hurdles; i.e. the specific sequences at the beginning and the end

Here is a brief overview of how to make hurdles:

  1. they are made on a long board (called a mould board) with nine holes drilled into it to take the uprights
  2. the uprights (or sails) go into the mould board
  3. lay in a starting sequence of small round rods in such a way that there are no loose ends hanging out
  4. then build up the height of the hurdle with split rods (hazel hurdles), twisting the tip of rod round the end of the hurdle and weaving it back in to hold it together
  5. finish with a sequence of round rods at the top – again, with no loose ends
  6. then trim the finished hurdle and take it out of the mould board

Saws or loppers may be useful, but the only essential tool is a bill-hook.

You can also often buy finished hurdles from Coppice Products.

You can then use your hurdles on your smallholding for penning or manoeuvring animals, for filling gaps in hedges or fences, or as windbreaks around your vegetable plots. They’ll last 6-8 years as outdoor fencing, but indefinitely if you keep them dry and under cover when you’re not using them.
