  1. The value of six key soil variables for incorporation into a South African forest site classification system

    The value of six key soil variables for incorporation into a South African forest site classification system

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The intensive nature of management practices in the exotic monoculture plantations of South Africa requires reliable decision support systems. Recent socio-economic developments, the need for optimal forest productivity, as well as increasing awareness of broader ecosystem values and environmental risks,...
  2. Variation in selected solid wood properties of young <em>Pinus patula</em> from diverse sites in the Mpumalanga escarpment area in South Africa

    Variation in selected solid wood properties of young <em>Pinus patula</em> from diverse sites in the Mpumalanga escarpment area in South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Regression analyses identified ‘Growth Days’ (an index expressing site moisture availability) as the only site variable contributing significantly to the prediction to wood density (R2 = 0.57), whereas the model predicting grain angle included only ‘Altitude’ (R2 = 0.60). These...
  3. 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...
  4. The Relationship between Site Characteristics and <em>Pinus radiata</em> Growth on the Tsitsikamma Plateau, South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    A site-growth study using a range of data from 46 plots on the Tsitsikamma plateau was undertaken for modelling the growth of Pinus radiata. Growth models for the prediction of site index at a reference age are imperative in an...
  5. Hypermedia and its Potential Use in Forestry Education

    Item type: Journal Article • Journal: South African Forestry Journal
    The role and use of Hypermedia as a multimedia information management tool in education is described. The associative structure of Hypermedia material, its interactive use, annotative facilities and the integrative use of multimedia makes Hypermedia a potentially effective tool and...
