    [Archive] Revised forecasts of the supply and demand for wood in the United Kingdom

    Lead Author: Adrian Whiteman
    This publication presents models of wood supply and wood product demand for the UK to 2050. The forecasts show that it is likely that wood supply will increase with demand up to 2025. After that, if no new planting is undertaken, supply will fall while demand will continue to rise (although in this respect there […]

    [Archive] Alternative silvicultural systems to clearcutting in Britain: a review

    Lead Author: Cyril Hart
    This Bulletin is written for landowners and foresters who wish to convert all or part of a wood or forest from pure, regular, uniform, even-aged stands to mixed, irregular, uneven-aged stands – in particular for those who desire to use silvicultural systems alternative to that of extensive clearcutting, with a view to achieving diverse structure […]

    [Archive] Provisional yield tables for poplar in Britain

    Lead Author: J.M. Christie
    Poplars are noted for their extremely rapid rates of growth. The development of new canker-and rust-resistant clones in Belgium and their introduction into Britain make them a very attractive crop to grow on suitable sites, such as former agricultural land. New tables are needed to reflect the more rapid rates of growth seen at spacings […]

    [Archive] Growing broadleaves for timber

    Lead Author: Gary Kerr
    Growing broadleaves for timber describes the silvicultural principles and practices involved in growing quality broadleaved timber in Britain. The aim of this Handbook is to update and expand one aspect of Forestry Commission Bulletin 62 Silviculture of broadleaved woodland, to focus attention on one single objective: growing high quality hardwood. This objective usually integrates well […]

    [Archive] The supply and demand for wood in the United Kingdom

    Lead Author: A. Whiteman
    This paper consists of two main parts. The larger part is concerned with new models of wood product demand that have been developed at the Forestry Commission. The rest of the paper then takes these models and, comparing them with future forecasts of UK roundwood production, examines the likely future raw material balance for wood […]

    [Archive] Sawmilling accuracy for bandsaws cutting British softwoods

    Lead Author: J.N. Smithies
    The dimensional accuracy with which timber is sawn is important both for its marketability and for its economic production. This Bulletin describes quality control techniques that can be used for sampling and measuring sawn timber taken from the production line in softwood sawmills. The dimensions obtained from the measuring process can be used to quantify […]

    [Archive] Mid-diameter volume tables (third edition)

    Lead Author: Forestry Commission
    This Field Book provides tables for estimating the volume of logs using the traditional mid-diameter method. Although it is a very accurate method, it becomes less accurate as the length increases. The volume is derived from the product of the length of the log and its mean cross-sectional area. In practice it is the diameter […]
