  1. Role of Eucalypt Plantations in Timber Supply and Forest Conservation in Sub-Saharan Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    The role of eucalypt plantations in timber supply and forest conservation in Sub-Saharan Africa was investigated. The annual destruction of 11,5 million ha of tropical forest is highlighted, the various causes indicated and the controversy whether fast-growing plantations and woodlots...
  2. Distribution, Size and Ownership of Forests in the Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    Indigenous forest of the southern Cape as delimited on 1:50 000 maps was analysed for distribution, size and ownership in six landscape zones: mountains, foothill, coastal platform, river valley, coastal scarp and dunes. I tested the hypothesis that forest distribution...
  3. Effect of weeding and fertilisation on bark thickness and stem form of seven pine species on a low-elevation site at Usutu, Swaziland

    Effect of weeding and fertilisation on bark thickness and stem form of seven pine species on a low-elevation site at Usutu, Swaziland

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    On a low-elevation site at Usutu alternative species to Pinus elliottii, the species recommended in the past for such sites, were planted to evaluate growth differences. At rotation age, destructive stem profile analyses were conducted on some of the trees...
  4. Securing African forests for future drier climates: applying ecophysiology in tree improvement

    Securing African forests for future drier climates: applying ecophysiology in tree improvement

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Increasing incidences of drought-induced tree mortality are being recorded worldwide, including Africa. African forests cover a significant proportion of the continent, which implies that African forest sustainability is threatened from a climate-change perspective. This is especially problematic in a developing...
  5. Differences in nitrogen cycling and soil mineralisation between a eucalypt plantation and a mixed eucalypt and <em>Acacia mangium</em> plantation on a sandy tropical soil

    Differences in nitrogen cycling and soil mineralisation between a eucalypt plantation and a mixed eucalypt and <em>Acacia mangium</em> plantation on a sandy tropical soil

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Sustainable wood production requires appropriate management of commercial forest plantations. Establishment of industrial eucalypt plantations on poor sandy soils leads to a high loss of nutrients including nitrogen (N) after wood harvesting. An ecological intensification of eucalypt plantations was tested...
  6. Role of site in the mortality and production of <em>Acacia mangium</em> plantations in Indonesia

    Role of site in the mortality and production of <em>Acacia mangium</em> plantations in Indonesia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    In Indonesia, Acacia mangium plantations exceed 1.6 Mha contributing approximately 3.5% of the country’s GDP. The viability of these plantations is increasingly threatened by fungal pathogens, insect pests, squirrels, monkeys, elephants and wind damage. Studies indicate that the problem is...
  7. Single-tree water use and water-use efficiencies of selected indigenous and introduced species in the Southern Cape region of South Africa

    Single-tree water use and water-use efficiencies of selected indigenous and introduced species in the Southern Cape region of South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    In South Africa, the development of a plantation tree industry using fast-growing introduced species was accelerated by the limited extent of indigenous forests. However, concerns about the impacts of plantations on the country’s limited water resources has initiated forest hydrology...
  8. Adjusting Faustmann's Formula for a Dynamic Financial Environment

    Item type: Journal Article • Journal: South African Forestry Journal
    The well-known LEV criterion or Faustmann's formula which evolved in the static financial environment of the nineteenth century is adjusted to take account of the changes in the dynamic financial environment of today. A previous incorrect attempt to adjust LEV...
  9. Financial Decision Criteria and Real Price Changes

    Item type: Journal Article • Journal: South African Forestry Journal
    General price indices such as the Consumer Price Index (CPI) or the Production Price Index (PPI) represent the weighted average of prices of a large number of goods and services. Such price indices therefore cannot accurately measure the changes in...
  10. A New Form of Internal Rate of Return

    Item type: Journal Article • Journal: South African Forestry Journal
    When the Internal Rate for Return (IRR) of a forestry project is calculated by means of traditional methods which ignore real price changes, the IRR for one rotation of the project is identical to the IRR for an infinite series...
