    [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] Monitoring of forest condition in Great Britain – 1989

    Lead Author: J.L. Innes
    The results of the 1989 forest condition monitoring programme are presented. A total of 7436 trees were assessed, with the species being restricted to Sitka spruce (Picea sitchensis), Norway spruce (P. abies), Scots pine (Pinus sylvestris), oak (Quercus spp.) and beech (Fagus sylvatica). Crown condition is now assessed on the basis of a variety of […]

    [Archive] Barn owl conservation in forests

    Lead Author: G. Shaw
    Barn owl numbers have declined over much of the British Isles. However, in northern Britain afforestation has resulted in some local increases. Young plantations with rank grassy vegetation contain large numbers of field voles which are the main food of barn owls. Abandoned farm buildings provide nest sites for the owls, but these deteriorate and […]

    [Archive] Forests and surface water acidification

    Lead Author: T.R. Nisbet
    This Bulletin reviews the evidence for a suggested forest effect in the acidification of surface waters in Great Britain. Acid deposition from the atmosphere within susceptible areas of Britain has affected fresh water flora and fauna, causing the decline and in some instances the complete loss of fish populations. Currently there is a debate about […]

    [Archive] Nitrogen deficiency in Sitka spruce plantations

    Lead Author: C.M.A Taylor
    On moorland and heathland soils in Great Britain nitrogen deficiency can severely restrict the growth of certain conifer species, including Sitka spruce, the main commercial species. Until the 1970s this was thought to be due solely to competition from heather and was commonly known as ‘heather check’. However, increased planting of Sitka spruce on very […]

    [Archive] The timbers of farm woodland trees

    Lead Author: J.D. Brazier
    Farmers are being encouraged to grow trees on surplus agricultural land as part of government policy effected through the Farm Woodland Scheme. The efficient production of timber is profitable, providing raw material for industry, yet it does not preclude other important objectives such as landscape design, amenity considerations, game management and wildlife conservation. The production […]

    [Archive] Dendroctonus micans in Britain – it’s biology and control

    Lead Author: C.J. King
    The great European spruce bark beetle (Dendroctonus micans) was first identified as a breeding species in Britain in 1982. This insect’s distribution, pest status, biology, life cycle and control methods are described. Although its present population is limited to Wales, the English West Midlands and Lancashire, it is well established. Infestations are characterised by scattered […]

    [Archive] The 1987 storm: impacts and responses

    Lead Author: A.J. Grayson (Ed)
    The storm which struck south-east England on the night of 15/16 October 1987 was the worst in the region since 1703: it caused more damage to woodlands and trees than any other recorded gale in Britain. Some 4 million cubic metres of timber were blown, equivalent to about 5 years’ cut in the seven worst […]

    [Archive] Monitoring of forest condition in the United Kingdom – 1988

    Lead Author: J.L. Innes
    The condition of forests in the United Kingdom is monitored through two projects undertaken by the Forestry Commission. The first, referred to throughout this publication as the long-term monitoring project, was started in 1984. It was developed in response to a growing concern that air pollution might be affecting the condition of trees in Britain. […]

    [Archive] Taxation of woodlands

    Lead Author: Forestry Commission
    This Bulletin explains the taxation of woodlands for the benefit of woodland occupiers (and their advisers). Part 1 deals with income tax and corporation tax following the major changes to the taxation of commercial woodlands made by the Finance Act 1988. Part 2 deals with the application of capital gains tax to disposals of woodlands. […]

    [Archive] A systems approach to forest operations planning and control

    Lead Author: M.A. Pritchard (Ed)
    Computer-based systems are now commonplace in most forestry operating environments. One of the inherent features of forestry everywhere is the amount of data collected over long periods of time. Information technology has made the storage and analysis of these data a cost effective reality. Never before has the forest manager been better placed to call […]
