    [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] 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] 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] 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] 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] 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] 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 […]
