  1. Response of <em>Ocotea bullata</em>, <em>Curtisia dentata</em> and <em>Rapanea melanophloeos</em> to medicinal bark stripping in the southern Cape, South Africa: implications for sustainable use

    Response of <em>Ocotea bullata</em>, <em>Curtisia dentata</em> and <em>Rapanea melanophloeos</em> to medicinal bark stripping in the southern Cape, South Africa: implications for sustainable use

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Tree bark is commonly used for traditional medicine in southern Africa and further afield. Increasing demand and commercialisation have resulted in the overexploitation of many species, posing a major challenge to forest managers to develop mechanisms for sustainable resource use...
  2. 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...
  3. Timber Harvesting in South Africa—Past, Present, Future

    Item type: Journal Article • Journal: South African Forestry Journal
    After a short description of South African timber harvesting practices in the past, the present situation in terms of machine population and the current harvesting and extraction methods is discussed in more detail.
  4. Growth, Yield and Timber Density of Short Rotation Coppice Stands of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of timing initial coppice reductions, number of reductions and final number of shoots per stool on growth and yield of Eucalyptus grandis are described. The basic data were obtained from three experiments situated in different climatic zones of...
  5. Cable Yarding in Southern Africa: An Analysis of its Productivity and Possible Procedure for its Improvement

    Item type: Journal Article • Journal: South African Forestry Journal
    The demand for timber in southern Africa is increasing and this is resulting in the afforestation of areas which require cable yarding when harvested. The demand for cable yarders, essentially fixed skylines, is therefore increasing rapidly. Stress is being placed...
  6. The Impact of Harvesting Operations on Timber Quality: Causes and Remedies

    Item type: Journal Article • Journal: South African Forestry Journal
    Forests are devastated daily to satisfy the world's timber demands. Tropical forests throughout the world are exploited and endangered. An obligation therefore exists to avoid damage to timber and minimise waste wherever possible.
  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. Patterns of selection of <em>Acacia karroo</em> by goats and changes in tannin levels and <em>in vitro</em> digestibility following defoliation

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Patterns of browse selection by Boer goats in a representative Acacia karroo community in the eastern Cape were studied. The rate of intake of browse was positively related to the leaf mass per unit length of the shoot. The ease...
  9. Some observations on rodent and antelope damage in commercial forest plantations

    Some observations on rodent and antelope damage in commercial forest plantations

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The impact of various weeding and site-preparation treatments on Acacia mearnsii and Pinus patula damage by mammalian pests was assessed. Browsing by small antelope on Acacia mearnsii was significantly less in areas where harvesting residues had been retained rather than...
  10. The development of harvesting schedules and post-harvesting management practices relative to oil yield of <em>Eriocephalus punctulatus</em>

    The development of harvesting schedules and post-harvesting management practices relative to oil yield of <em>Eriocephalus punctulatus</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The first phase in the domestication programme of Eriocephalus punctulatus involved establishing how this crop could be harvested without adversely affecting plant vigour and longevity. The second phase of the domestication programme was the development of harvesting schedules that would...
