  1. Evaluation of the grazing potential of grass species in <em>Tarchonanthus</em> veld of the northern cape<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The grazing value of the seven most prominent grass species in Tarchonanthus‐limeveld was investigated from 1977 to 1981.
  2. Veld composition in relation to grazing capacity <em>die verhouding tussen veld samestelling en weidingskapasiteit</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Present methods of evaluating veld composition in relation to grazing capacity can be criticised on grounds of subjectivity, especially with regard to the assignment of relative values to the constituent species. Data relating to botanical composition and estimated grazing capacity,...
  3. A study of variations in floristic composition of highveld in the eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Floristic surveys of two 1500m line transects in veld provided data which indicated the nature of variations in veld composition, expressed in terms of species, palatability classes or weighted palatability classes. The transects were subjectively subdivided into units comprising relatively...
  4. Die invloed van ontblaring en vog op die tanien‐ en polifenolinhoud van <em>Portulacaria afra</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The influence of defoliation and moisture on the tannin and polyphenol contents of Portulacaria afra. To determine whether tannin and total polyphenol contents of Portulacaria afra change owing to damage, different trees were subjected to three intensities of defoliation, namely,...
  5. A survey of grazed and ungrazed grassland in the south‐eastern Transvaal highveld 1. Palatability composition and grazing capacity

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The floristic composition of selected veld communities which by virtue of their location were ungrazed, but regularly burned, and which were judged to reflect potential floristic composition, was measured at 112 sites in the southeastern Transvaal highveld. At each site...
  6. Variations in floristic and palatability composition, yield of veld and of soil characteristics on a paddock scale

    Variations in floristic and palatability composition, yield of veld and of soil characteristics on a paddock scale

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Five parallel 900-m line-transects were laid out 100 m apart in relatively homogeneous veld. Floristic composition, yields of dry matter, soil forms and series, effective depth, clay content of the top and subsoil, and the pH of the topsoil were...
  7. The quantification of grazing capacity from grazing — and production values for forage species in semi-arid grasslands of southern Africa

    The quantification of grazing capacity from grazing — and production values for forage species in semi-arid grasslands of southern Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The relation between rangeland condition and grazing capacity was determined along a degradation gradient. In studying agronomic values of forage species, the average production per tuft was combined with its grazing preferences, to link grazing values for species in the...
  8. The effect of defoliation and competition on the regrowth of <em>Themeda triandra</em> and <em>Aristida junciformis</em> subsp. <em>junciformis</em>

    The effect of defoliation and competition on the regrowth of <em>Themeda triandra</em> and <em>Aristida junciformis</em> subsp. <em>junciformis</em>

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The effects of a cutting trial, conducted to study the combined influence of defoliation and competition from surrounding vegetation on the vigour of Themeda triandra and Aristida junciformis, were evident after the single season of treatment implementation. Aristida junciformis was...
  9. Research note: Evaluation of the reliability of local farmer knowledge in Namaqualand, South Africa

    Research note: Evaluation of the reliability of local farmer knowledge in Namaqualand, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Local farmer knowledge of species distribution patterns and plant palatability in Namaqualand, South Africa, was assessed using Participatory Rural Appraisal techniques. These findings were compared with the results obtained using phytosociological techniques (species distribution), and with palatability indices published in...
  10. Responses to sheep browsing at different stocking rates: Water relations, photosynthesis and carbon allocation in two semi‐arid shrubs

    Responses to sheep browsing at different stocking rates: Water relations, photosynthesis and carbon allocation in two semi‐arid shrubs

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The ecophysiological responses of two karoo shrubs to sheep browsing at different stocking rates were studied. The responses of a relatively unpalatable shrub (Pteronia tricephala), and of a shrub of greater palatability (Eriocephalus ericoides) were examined at high, intermediate and...
