  1. Role of supply chain management in the wise use of wood resources

    Role of supply chain management in the wise use of wood resources

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    One of the cornerstones ofsustainable forestry is the wise use ofwoodresources to achieve maximum value or benefit for society, while not jeopardizing the future. At the same time forest companies must compete on an international scale, otherwise they themselves risk...
  2. “Shorthaul” pulpwood transport in South Africa. A network analysis case study

    “Shorthaul” pulpwood transport in South Africa. A network analysis case study

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Shorthaul transport, also known as secondary intermediate transport (SIT), is a feature of pulpwood transport in South Africa. SIT is an additional transport phase within traditional secondary transport. It originates at roadside landing or depot and terminates at another depot,...
  3. Modelling of wander ratios, travel speeds and productivity of cable and grapple skidders in softwood sawtimber operations in South Africa

    Modelling of wander ratios, travel speeds and productivity of cable and grapple skidders in softwood sawtimber operations in South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The objective of this study was to develop predictive models for cable and grapple skidder wander ratios, travel speeds (loaded and unloaded), and productivity in softwood roundwood sawtimber harvesting operations. For field data collection, the study utilised on-board computing systems...
  4. Softwood sawlog secondary transport travel speed prediction for the South African forestry industry

    Softwood sawlog secondary transport travel speed prediction for the South African forestry industry

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The objective of this study was to develop a predictive model for travel speed of softwood sawlog timber transport (STT) vehicles over a range of forest and provincial roads of varying condition for the South African forestry industry. Data was...
  5. Fibre losses during debranching and debarking of <em>Eucalyptus</em> pulp logs using a single-grip harvester

    Fibre losses during debranching and debarking of <em>Eucalyptus</em> pulp logs using a single-grip harvester

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Mechanised harvesting operations are becoming more prevalent in South Africa, with the realisation that motor- manual and manual harvesting operations pose significant health and safety risks to workers. However, the potential damage caused by single-grip harvester feed rollers and delimbing...
  6. The impact of mechanical log surface damage on chip size uniformity during debranching and debarking <em>Eucalyptus</em> pulpwood logs using a single-grip harvester

    The impact of mechanical log surface damage on chip size uniformity during debranching and debarking <em>Eucalyptus</em> pulpwood logs using a single-grip harvester

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Mechanised harvesting operations are becoming more prevalent in South Africa with the realisation that motormanual and manual harvesting operations pose significant health and safety risks to workers. The damage inflicted by single-grip harvester feed rollers and delimbing knives on log...
  7. A South African softwood sawtimber supply chain case study

    A South African softwood sawtimber supply chain case study

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Supply chain management principles were analysed by investigating the effects of smaller-scale and incremental interventions in a forest-to-mill value chain on financial returns and forest resource use in an Eastern Cape case study area. Three previous studies provided input by...
  8. The impact of log surface damage caused by harvester <em>Eucalyptus</em> debarking on pulp value recovery

    The impact of log surface damage caused by harvester <em>Eucalyptus</em> debarking on pulp value recovery

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Mechanised harvesting operations are growing in popularity in South Africa, as motor-manual and manual harvesting operations pose significant health and safety risks to workers. Potential damage inflicted by single-grip harvester feed rollers and delimbing knives on the log surface during...
  9. Provincial road condition and round wood timber transport in South Africa

    Provincial road condition and round wood timber transport in South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The context of the study is the concern over declining provincial road conditions due to insufficient government funding for road maintenance. The roads are used by a wide variety of commercial and private interests that contribute a broad range of...
  10. A framework for analyzing workforce dynamics in forest harvesting in South Africa

    A framework for analyzing workforce dynamics in forest harvesting in South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    People are the industry's most valuable asset. However, due to its dynamic nature, labour cannot be owned but only rented. A framework for measuring, monitoring and managing labour dynamics is used and tested in forest harvesting operations in South Africa...
