| The source of dried buckthorn bark, the alder buckthorn, is a shrub native to Europe and western parts of Asia. |
| The River Derwent was brown and high, ducks sheltered in eddies, and little birds flitted from alder to willow to alder. |
| Just 14 acrres of broadleaf woodland remain, including oak, ash, alder and birch and several large yew trees. |
| Apple, willow, birch, poplar, citrus, alder and maple are varieties we have used. |
| The native trees planted include oak, ash, birch, alder, hazel, yew, and Scots pine. |
| The picture is then traced onto the boards, using a pointer or toothed wheel, and marked out with cones from the alder tree or with coffee beans. |
