  1. <em>Perspective article</em>: The evolving use of stocking rate indices currently based on animal number and type in semi‐arid heterogeneous landscapes and complex land‐use systems

    <em>Perspective article</em>: The evolving use of stocking rate indices currently based on animal number and type in semi‐arid heterogeneous landscapes and complex land‐use systems

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Methods of determining stocking rate based on metabolic mass, animal type and biomass are reviewed in the context of equilibrial/disequilibrial paradigms. In South Africa, the calculation of ‘carrying capacity’ is based on conversion of animal species to metabolic mass equivalents...
  2. A global assessment of Holistic Planned Grazing™ compared with season-long, continuous grazing: meta-analysis findings

    A global assessment of Holistic Planned Grazing™ compared with season-long, continuous grazing: meta-analysis findings

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    It has been claimed that Holistic Planned Grazing™ (HPG), a type of rotational grazing, can increase productivity in rangelands and reverse climate change while doubling the stocking rate, mainly through the impact of densely bunched animals on primary production. Previous...
  3. Access Development in South African Mountainous Plantations—Problems, Trends, Research

    Item type: Journal Article • Journal: South African Forestry Journal
    The forest road network in South Africa's plantations was rapidly developed to provide access for planting, fire protection and later logging. The result today is a fairly high road density of rather low standard roads!
  4. 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...
  5. 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...
  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. The ecological potential of the kudu for commercial production in savanna regions

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    This paper considers the choice of a browsing ungulate to supplement cattle in savanna regions susceptible to problems of bush encroachment, and evaluates the kudu in particular. Relevant aspects of its ecology considered include (i) the vegetation components utilized at...
  8. Recent trends in grazing management philosophy in South Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Reasoned argument by researchers in veld management in South Africa and elsewhere has not generally supported a number of contentious recommendations made in recent years in the popular and semi‐popular press. The only major changes to general management thinking has...
  9. Towards a method of assessing the veld condition of the valley bushveld in the Eastern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Currently, no technique is available for assessing the condition of Valley Bushveld in the Eastern Cape. The objective of this investigation was to develop a method of scoring bushveld according to its productive condition. It was established, through principal component...
  10. Preliminary observations on the ability of goats to control post‐burning regrowth in <em>acacia nigrescens/combretum apiculatum</em> Savanna in Botswana

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A ten hectare block which had been burned with an intense surface head fire was stocked at the rate of one goat per hectare to control the woody regrowth. After one year the block was subdivided and in one half...
