Coppicing is a traditional method of woodland management, by which young tree stems are cut down to a low level, or sometimes right down to the ground. In subsequent growth years, many new shoots will grow up, and after a number of years the cycle begins again and the coppiced tree or stool is ready to be harvested again. Typically a coppice woodland is harvested in sections, on a rotation. In this way each year a crop is available. This also has the side-effect of providing a rich variety of habitats, as the woodland always has a range of different aged stools growing in it. This is beneficial for biodiversity.
