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] 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 […]

    [Archive] Assessment of tree condition

    Lead Author: J.L. Innes
    Forest condition is now assessed annually in most European countries. This Field Book provides details of assessment procedures used by the Forestry Commission in their main monitoring programme. Although this programme is restricted to Sitka spruce, Norway spruce, Scots pine, oak and beech, the techniques that are described are applicable with little or no modification […]

    [Archive] Champion trees in the British Isles (3rd edition)

    Lead Author: A.F. Mitchell
    This listing includes species down to a considerable degree of rarity and only the very rarest, which have too few known specimens to compete effectively as tallest and stoutest are excluded; but where one specimen is clearly of outstanding size it is included even where very few are known. The more important cultivars are included. […]

    [Archive] Classification and presentation of softwood sawlogs

    Lead Author: Forestry Commission
    These recommendations are agreed by Forest Enterprise, the British Timber Merchants' Association, and the UK Softwood Sawmillers Association. The normal practice of the Forestry Commission will be to classify parcels of sawlogs offered for sale into four categories: green, red, short green, and log pole, for which descriptions are given. The FC aims to maximise […]

    [Archive] Nursery stock root systems and tree establishment – a literature review

    Lead Author: Jenifer J. White
    This Occasional Paper is a literature review which was undertaken in 1984 to establish what is known about tree root systems, their size in relation to the shoot and the nutrient/moisture status needed for good root regeneration after planting. The specific objectives of the review were:1. to prepare a report summarising the available in formation […]

    [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] Trends in forestry research 1982-1988

    Lead Author: D.A. Burdekin
    Increasing interest in forestry in Britain has followed the search for alternative land uses to agriculture and the growing importance of conservation. Research requirements have adapted to this new situation. This Occasional Paper looks at recent trends and seeks to ask whether resources are reasonably matched to requirements. At least seven public agencies are engaged […]
