  1. The regrowth of <em>Colophospermum mopane</em> following clearing

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The recovery of cleared Colophospermum mopane thicket in the eastern Transvaal lowveld, to a level where its effect on grass production is similar to that in the pre‐cleared state, occurs within fourteen years. Based on certain assumptions, the ‘effective duration’...
  2. Comparative patterns of sodium accumulation in leaves of selected savanna species growing on sodic and nonsodic soils

    Comparative patterns of sodium accumulation in leaves of selected savanna species growing on sodic and nonsodic soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Plants show differing mechanisms of tolerance to high sodium levels in soils. Physiological and biochemical mechanisms have been investigated for many crop species but little information is available for indigenous tree and grass species. Foliar concentrations of sodium, calcium, potassium,...
  3. Book Review

    Book Review

    Item type: Journal Article • Journal: The Southern African Forestry Journal
  4. The distribution of sweetveld and sourveld in South Africa's grassland biome in relation to environmental factors

    The distribution of sweetveld and sourveld in South Africa's grassland biome in relation to environmental factors

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The distribution of sweet‐ and sourveld in relation to climate, parent material and soil nutrients has been examined in South Africa's grassland biome. Sourveld occurs in areas with high water supply and where parent material gives rise to soils with...
  5. Application of the 3-PG model to a <em>Eucalyptus grandis</em> stand subjected to varying levels of water and nutritional constraints in KwaZulu-Natal, South Africa

    Application of the 3-PG model to a <em>Eucalyptus grandis</em> stand subjected to varying levels of water and nutritional constraints in KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The 3-PG model has shown considerable potential as a tool for predicting forest productivity. As part of a model validation exercise, 3-PG was applied to an irrigated and fertilised Eucalyptus grandis stand in the KwaZulu-Natal Midlands. Simulations were run over...
  6. Prescribed under-canopy burning in <em>Pinus patula</em> plantations of the Mpumalanga highveld: The effects of fire on tree growth

    Prescribed under-canopy burning in <em>Pinus patula</em> plantations of the Mpumalanga highveld: The effects of fire on tree growth

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The effect of controlled undercanopy burning on tree growth has been studied under 16-year-old Pinus patula trees in Mpumalanga. Three fire intensity treatments and a control "no-burn" treatment, were applied to 1 ha plots. Average fuel depth was 42cm with...
  7. Factors Influencing the Long Term Sustainability of the South African Forest Industry

    Factors Influencing the Long Term Sustainability of the South African Forest Industry

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    We discuss five issues which we feel will have a major influence on the long term sustainability of the South African forest industry. These are: water, site fertility, labour issues, environmental issues, and national and international market forces. Specifically, we...
