There has been a concerted shift from traditional motor-manual and semi-mechanised timber harvesting systems to mechanised cut-to length (CTL) operations in South Africa. This is particularly true in Eucalyptus pulpwood felling and processing, South Africa’s largest commercial wood resources used in the pulp and paper industry. Mechanisation improv...
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 debranching and debarking of eucalypts may affect chip size...
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. The damage inflicted by single-grip harvester feed rollers and delimbing knives on log surfaces during debranching and debarking eucalypts, may affe...
Chip moisture content and especially its uniformity impact kraft pulping. However, the effect of pulp log moisture content on chip quality during chip production is not well known. Chip size distribution is important in kraft pulping as it impacts chemical use, pulp quality and recovery. This study investigated the influence of two pulp log drying...
This study investigates the possible socioeconomic impact of the phasing out of nearly 22 500 ha of plantations within the Southern and Western Cape regions of South Africa as a result of a decision made by government in 2000. Data was collected in 2007 from three plantations (one near Grabouw in the Western Cape, and two near George in the Souther...

Durch die Globalisierung, Internationalisierung und sich verändernde forstliche Arbeitsfelder ist die forstwissenschaftliche Ausbildung in der Informationsgesellschaft des 21. Jahrhunderts weitreichenden Veränderungen unterworfen. Heutige Absolventen müssen neben den klassischen forstwissenschaftlichen Grundlagen eine Vielzahl zusätzlicher Kompeten...
With the changing role of forestry worldwide, globalization and forestry policy shifts, especially in African countries, educational institutions have to improve course quality and equip their graduates with a variety of non-traditional skills. Blended or Hybrid Learning, offering a flexible combination of traditional face-to-face education with th...
Educational institutions today are confronted with the challenge of finding innovative ways to attract and retain students and to improve course quality and flexibility. They are also required to improve efficiency, increase graduates' success in the labour market and create new streams of revenue. In addition, with changing roles of forests worldw...
