Coppicing is a conventional method of woodland organization in which young tree stems are cut down to a low level. In subsequent growth years, many new shoots will come out 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 has the side-effect of as long as a rich variety of habitats, as the woodland always has a range of dissimilar aged stools growing in it. This is helpful for biodiversity. The cycle length depends upon the species cut, the local custom, and the use to which the product is put. Birch can be coppiced for faggots on a 3- or 4-year cycle, whereas oak can be coppiced over a 50-year cycle for poles or firewood.
