  1. A comparison of highveld fodders and fodder flows for growing out long yearling steers

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A fodder flow/animal experiment 40,8 ha in extent (7,5 ha irrigated), with 19 paddocks, was carried out over a two and a half year period.
  2. An evaluation of the economic viability of commercial pastoralism in the <em>smaldeel</em> area of the Eastern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Carrying capacity models and financial data from study group farmers were used to derive attainable net revenue per ha on veld in good, moderate and poor condition. From these data, minimum farm sizes required for a reasonable standard of living...
  3. Correlates of stocking rate and overgrazing in the Leliefontein Communal Reserve, central Namaqualand

    Correlates of stocking rate and overgrazing in the Leliefontein Communal Reserve, central Namaqualand

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We investigate the correlates of stocking rate in the Leliefontein communal reserve and attempt to provide a mechanistic explanation of the controlling factors. We further speculate on how high stocking rates are maintained in relation to the current state of...
  4. The effects of topo-edaphic variables and cultivation on the woody vegetation of Weenen Nature Reserve, KwaZulu-Natal

    The effects of topo-edaphic variables and cultivation on the woody vegetation of Weenen Nature Reserve, KwaZulu-Natal

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The soil types and woody vegetation of Weenen Nature Reserve (WNR), KwaZulu-Natal, were described. Mispah, overlying shale, and Shortlands, overlying dolerite were the most common of 18 the soil forms encountered. Six vegetation types were identified by TWINS PAN which...
  5. Kudu foraging behaviour: influenced by animal density?

    Kudu foraging behaviour: influenced by animal density?

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    In deciduous savanna a marked decline in browse availability characterises the late dry season and apparently regulates populations of large browser species such as kudu. The dry season utilisation patterns of two woody species, Acacia tortilis and Boscia albitrunca, in...
  6. The relation between herbivore density and relative resource density at the landscape level: Kudu in semi‐arid savanna

    The relation between herbivore density and relative resource density at the landscape level: Kudu in semi‐arid savanna

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Ecological theory can help range scientists to understand the determinants of ecological animal density or, in range management terms, ‘carrying capacity’. The relation between the relative density of resources and herbivore density is illustrated by regressions of the ecological density...
  7. An analysis of a stocking rate trial at Chobela, southern Mozambique

    An analysis of a stocking rate trial at Chobela, southern Mozambique

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    An analysis is presented of data from a stocking rate trial carried out in 1962–1963 at Chobela Livestock Station in southern Mozambique. The data set had limitations but an attempt was made to draw any conclusions possible for management. Data...
  8. Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Determination of carrying capacity for mixed‐ or multi‐species grazing systems is complex. Commonly, each species is compared to the standard large stock unit (LSU) used in conventional agriculture. However, this approach does not allow for ecological separation, and thus overlooks...
  9. <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...
  10. Savanna browse production. 1: Determinants and measurement

    Savanna browse production. 1: Determinants and measurement

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    With the rapid expansion of wildlife ranching and conservation in South African savannas and the resultant increase in multi-species grazing and browsing systems, information on browse production potential is essential for determination of carrying capacity. This study, conducted on three...
