  1. Bark removal for medicinal use predisposes indigenous forest trees to wood degradation in Zambia

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    Bark harvesting for medicinal purposes has become widespread in Zambia, mainly due to the high levels of poverty among the population. The injury caused to trees leads to wood deterioration as a result of insect damage and fungal infection. This...
  2. Site Relationships for Some Wood Properties of Pine Species in Plantation Forests of Southern Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    Although genetic variation in wood properties of the three main pine species planted in southern Africa is high, there are important site relationships.
  3. Impact of Wood Quality Assessments on Future Fibre Resources in the Pulp and Paper-making Industry

    Item type: Journal Article • Journal: South African Forestry Journal
    Recent evidence from research in Europe has indicated that individual trees can be sampled for their pulping properties by the removal of small quantities (5–50 g) of wood at about breast height (1,3 m above ground). Work began at Sappi's...
  4. Effect of Initial Spacing and Thinning on Some Wood Properties of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    A study was made of the effect of thinning intensity on wood density and some wood anatomical properties and their within-tree variation patterns, as well as the extent to which the development of growth-stress splits in logs and sawn boards...
  5. The Effects of Phosphorus and Dolomitic Lime on the Production and Volumetrical Conversion Factors of <em>Eucalyptus grandis</em> Wood

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of phosphorus and dolomitic lime applications on the stacked wood volume, dry wood weight and form, bark and stacking factors of Eucalyptus grandis Hill ex Maiden trees are presented. The rates of phosphorus (0 kg, 200 kg and...
  6. The Wood Properties and Qualities of Three South African-Grown Eucalypt Hybrids

    Item type: Journal Article • Journal: South African Forestry Journal
    Hybridisation is becoming an increasingly important technique in tree breeding to improve yields, adaptability and wood quality. In this study, sample material from crosses of Eucalyptus grandis with E. tereticornis, E. camaldulensis and E. urophylla established on sites of which...
  7. Seasonal Fluctuations and Diversity of Bark and Wood-boring Beetles in Lowland Forest: Implications for management Practices

    Item type: Journal Article • Journal: South African Forestry Journal
    The phenology and diversity of wood-living beetles attacking Cedrela mexicana, Khaya nyasica and Milicia excelsa were observed for one year with weekly window-flight-trap collections. A total of 150 species (10 known to be common pests of timber) were collected, most...
  8. Basic Density, Tracheid Length and Strength Properties of Juvenile and Mature Wood of <em>Pinus patula</em> Grown in Tanzania

    Item type: Journal Article • Journal: South African Forestry Journal
    More than 70% of Tanzanian plantations consist of conifers, 60% of which are Pinus patula plantations. Juvenile wood is one of the most important sources of variability.
  9. Are multi‐paddock grazing systems economically justifiable?

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The financial implications of few‐ and multi‐paddock systems were modelled by a discounted cash flow analysis with the (discounted) present value as the dependent variable, and number of paddocks, farm run‐down time, time horizon and discount rate as the independent...
  10. The effect of planting density on the wood quality of South African-grown <em>Eucalyptus grandis</em>

    The effect of planting density on the wood quality of South African-grown <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    This paper presents the results of a wood property and sawn board quality study performed on disc samples and sawlogs taken from a 23-year-old Eucalyptus grandis Nelder 1a spacing trial at J.D.M. Keet plantation near Tzaneen. Ten trees from each...
