    [Archive] Thetford Forest Park: the ecology of a pine forest

    Lead Author: Philip Ratcliffe
    This Technical Paper includes papers from the Thetfore symposium of 1991. The symposium was designed to gather together the results of a wide range of research which collectively have added greatly to our understanding of this pine forest ecosystem and influenced its management. The intended audience is woodland managers and ecologists and anyone with an […]

    [Archive] Designing forest edges to improve wind stability

    Lead Author: Barry Gardiner
    Forest edges are important for the stability, visual impact and biodiversity of forests. Improved design of edge plantings will enhance the benefits they provide. Wind tunnel experiments are described and results indicate the effect of different edge treatments on stability. Practical methods for creating edges that can improve forest stability and visual appeal are discussed. […]

    [Archive] Experiments on lodgepole pine seed origins in Britain

    Lead Author: Roger Lines
    The range of lodgepole pine extends over 26 million hectares of north-west America, where climates vary from the bitter cold Yukon to the very mild Californian coast. It occurs from sea level to 3900 min elevation. Over millions of years it evolved into a species which shows more variability than any other conifer. Practical forest […]

    [Archive] Borates for stump protection: a literature review

    Lead Author: J.E. Pratt
    The use of borates for the control of Fomes root and butt rot of conifers is reviewed in relation to the history of their use in wood preservatives, their efficacy as stump treatment materials, and their effect on the environment. Effectiveness, phytotoxicity, vertebrate toxicity, and environmental impact are all considered. Borates are effective in controlling […]

    [Archive] The native woodland resource in the Scottish highlands

    Lead Author: Neil A. Mackenzie
    Provides a summary account of the present extent, distribution, composition and condition of the native woodlands of the Highlands, which at over 210,000 ha is substantially greater than had previously been recognised. Half is of natural origin and half is of planted origin native woodland. Birch, Scots pine and oak are the commonest native species. […]

    [Archive] The use of treeshelters: 1992 survey

    Lead Author: Gary Kerr
    The correct use of treeshelters is important to ensure successful and rapid early establishment of young trees. Almost 200 sites were surveyed with the object of comparing actual usage of treeshelters with the recommendations (see FC Handbook 7). Effective weed control is essential with use of treeshelters. Height of treeshelters must take into account the […]

    [Archive] Decline in sitka spruce on the South Wales coalfield

    Lead Author: M.P. Coutts
    This Technical Paper describes a collaborative effort to explain the reduced growth at time of canopy closure or later of Sitka spruce on parts of the South Wales coalfield. Stem analysis showed that growth had declined steeply over a period of about four years. Decline was associated with thin crowns and with bending of the […]

    [Archive] Managing forests for biodiversity

    Lead Author: Richard Ferris-Kaan
    Managing Forests for Biodiversity was the title of a one-day symposium, organised by the British Ecological Society’s Forest Ecology Group, and held at the Maybury Hotel, Edinburgh on 2 September 1992. This Technical Paper is a record of papers presented at the symposium plus additional information, preceded by a brief introductory review. The symposium was […]

    [Archive] Champion trees in the British Isles

    Lead Author: Alan F. Mitchell
    Measurements of exceptional trees have been recorded for a considerable number of years: initially out of curiosity, especially about maximum size, and then to investigate the potential for growth and productivity according to species and situation. The Forestry Commission tree register provided all the measurements for early editions of this title. The register was begun […]

    [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] The private woodlands survey

    Lead Author: C.P. Mitchell
    In 1990, the future of the Private Woodlands Survey was reconsidered by the Forestry Commission. Its original purpose had been to inform interested parties on reviews of planting grants. In recent years, however, a change in the economic rationale underlying grant-aid to private woodland owners has been increasingly recognised. This means that the primary basis […]

    [Archive] Forest nursery herbicides

    Lead Author: David Williamson
    Information is given on the use of forest nursery herbicides. Much of this information is based on the results of Forestry Commission experiments. A brief description of the types of herbicides is given followed by information on the various herbicides which can be used at the different stages of forest nursery stock production. This publication […]

    [Archive] Black grouse and forestry: habitat requirements and management

    Lead Author: John Cayford
    The black grouse is a large, sexually dimorphic species found typically in habitats transitional between moorland and forest. Numbers of black grouse have recently declined throughout much of Europe. In Britain, the species is now largely confined to Scotland, the north of England and Wales. Continued loss and fragmentation of habitat represents the most serious […]

    [Archive] Deterioration of fine tree roots during cold storage in two contrasting winters

    Lead Author: Helen McKay
    Electrolyte leakage from fine roots was measured before and after 30 and 90 days cold storage. The effect of the entry date and the length of cold storage were examined during the exceptionally mild winter of 1989-90 and the more typical winter of 1990-91. In the first year, roots from 2-year-old transplants and undercuts of […]

    [Archive] The carbon content of trees

    Lead Author: George Matthews
    Calculations of the quantities of carbon stored by trees requires a knowledge, not only of their growth rates, but also of the proportions of carbon contributing to their chemical make-up. This Technical Paper presents the results of a search of the literature for reported values for carbon contents and results of estimations of carbon contents […]
