  1. 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...
  2. Nitrogen and phosphorus concentration in faeces: an indicator of range quality as a practical adjunct to existing range evaluation methods

    Nitrogen and phosphorus concentration in faeces: an indicator of range quality as a practical adjunct to existing range evaluation methods

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Vegetation monitoring, currently complemented by climatic data in particular rainfall areas, does not always supply sufficient information to provide reliable guidelines for appropriate stocking densities on ranch or reserve scale. This paper considers how the nutrient status of animals may...
  3. Determining spatial and temporal variability in quantity and quality of vegetation for estimating the predictable sustainable stocking rate in the semi-arid savanna

    Determining spatial and temporal variability in quantity and quality of vegetation for estimating the predictable sustainable stocking rate in the semi-arid savanna

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    This study assessed the importance of spatial and temporal variation in plant quality and quantity for determining sustainable stocking rates in game, commercial and communal ranches in semi-arid savanna of the Northern Cape Province, South Africa, in wet and dry...
  4. <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...
  5. Effect of stocking density on vegetation and animal performance within the semi-arid shrublands of the Karoo, South Africa

    Effect of stocking density on vegetation and animal performance within the semi-arid shrublands of the Karoo, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    As the primary land use in the Karoo, extensive small-stock farming contributes significantly towards the agricultural economy of the region. However, the sustainability of this practice has been questioned for many years. This led to the establishment of a long-term...
  6. The effect of Holistic Planned Grazing™ on African rangelands: a case study from Zimbabwe

    The effect of Holistic Planned Grazing™ on African rangelands: a case study from Zimbabwe

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Holistic Planned Grazing™ (HPG) is purported to have positive long-term effects on rangelands, enhancing ecosystem services. Given comparable environmental templates, but different management regimes, vegetation monitoring and landscape function analysis showed the Africa Center for Holistic Management (ACHM) at Dimbangombe...
  7. 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!
  8. 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...
  9. 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...
  10. 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...
