  1. 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...
  2. A consideration of veld condition assessment techniques for commercial livestock production in South Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A number of procedures have been developed for the evaluation of veld condition in a variety of vegetation types in South Africa. These include both agronomic and ecologically based methods, about which there still remain a great deal of controversy...
  3. Groei en produksie van ‘n aanal aangeplante weidings onder beweiding

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die groei en produksie onder beweiding van ‘n aantal aangeplante weidings is met behulp van die verskilmetode bepaal. Uit die data verkry in die proef is dit duidelik dat indien daar besproeiingswater beskikbaar is, groen materiaal dwarsdeur die jaar voorsien...
  4. The effect of severe drought and management after drought on the mortality and recovery of semi‐arid grassveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The False Thornveld of the Eastern Cape experienced a particularly intense drought during the 1982/83 growing season. Extensive grass mortality took place during the drought. After the drought, recovery was particularly sensitive to the post‐drought management treatment applied. Veld that...
  5. A comparison of some range condition assessment techniques used in southern African grasslands

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Techniques currently used to assess range condition in the grassland biome of southern Africa are reviewed. The methods were used to calculate range condition indices from fire‐climax and climatic‐climax grassland data. These indices were then used to evaluate each method...
  6. The use of degradation gradients for the assessment and ecological interpretation of range condition

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Multivariate procedures were used to subdivide the southern African climatic climax grasslands of the 700–800‐mm rainfall zone into relatively homogeneous grazing areas. A degradation gradient was constructed for each of these areas. This was done by means of centred PCA...
  7. Inter‐related floristic changes associated with different long‐term grazing treatments in Sourish Mixed Bushveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Eight camps, grazed annually during different seasons by steers, were surveyed. Herbaceous species were grouped into Decreaser and Increaser categories according to their reaction to grazing. The Increaser IIa (light overgrazing) and IIb (moderate overgrazing) herbaceous species were the most...
  8. Patterns of plant selection by grazing cattle in two savanna grasslands: A plant's eye view

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The amount of grazing experienced by individual tufts of the most abundant perennial grasses of two Transvaal savannas was monitored at regular intervals for two growing seasons. In general, Setaria incrassata and Themeda triandra were heavily grazed, Bothriochloa insculpla and...
  9. A degradation gradient for the assessment of rangeland condition of a semi-arid sourveld in southern Africa

    A degradation gradient for the assessment of rangeland condition of a semi-arid sourveld in southern Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Data collected between 1986/87 and 1999/2000 from a long-term rangeland monitoring project on three different sites were used to construct a degradation gradient in a semi-arid sour grassland of southern Africa. The degradation gradient was then used to quantify rangeland...
  10. Identification of key grass species under grazing in the Highland Sourveld of Natal

    Identification of key grass species under grazing in the Highland Sourveld of Natal

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Relative abundances of rangeland species have for many years been used to index trends in range condition following the impact of grazing. All species recorded in a botanical survey are usually classified according to their assumed reaction to grazing using...
