  1. Prescribed under-canopy burning in <em>Pinus patula</em> plantations of the Mpumalanga highveld: The effects of fire on tree growth

    Prescribed under-canopy burning in <em>Pinus patula</em> plantations of the Mpumalanga highveld: The effects of fire on tree growth

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The effect of controlled undercanopy burning on tree growth has been studied under 16-year-old Pinus patula trees in Mpumalanga. Three fire intensity treatments and a control "no-burn" treatment, were applied to 1 ha plots. Average fuel depth was 42cm with...
  2. Curing Rates in the Grass Sward of the Highland Sourveld in the Natal Drakensberg

    Item type: Journal Article • Journal: South African Forestry Journal
    Data on the curing rates of one, two and three-year-old grassland are presented. Curing is initiated at the end of April and progresses rapidly up to the middle of May. By June the grasses are 95 % cured, increasing the...
  3. The effect of thirty years of burning on the Highland Sourveld of Natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A veld condition assessment was used to determine the effect of past burning treatments on the species composition of Highland Sourveld at Cathedral Peak. Veld condition scores in grassland protected from fire were significantly lower than where veld had been...
  4. Fire behaviour in the Kruger National Park

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Fire research in the Kruger National Park has largely been focussed on the effect of the season and frequency of burning on the vegetation. Very little information is available on the effect of fire behaviour and in particular fire intensity,...
  5. The dynamics of <em>Themeda Triandra</em> tillers in relation to burning in the natal Drakensberg

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Marked tillers of Themeda triandra were sampled regularly over a two year period in Highland Sourveld burnt annually in winter, biennially in spring and after a single summer and early winter burning treatment. Parameters recorded were height of shoot apex,...
  6. Effect of fire intensity on the grass and bush components of the Eastern Cape thornveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Fire intensity is an important component of the fire regime and its effect on the grass sward and bush were investigated in the Eastern Cape thornveld. Research indicated that fire intensity had no effect on the recovery of grass after...
  7. <em>Leucosidea sericea</em> — control in southern Lesotho

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Tebuthiuron chemical treatments were effective in controlling Leucosidea sericea shrubs upon rangelands of the Quthing sheep stud station in southern Lesotho. Cutting treatments were also effective but more labour intensive. Repeated applications of 2,4,5‐T and fire resulted in less mortality...
  8. A critical analysis of veld management recommendations for sourveld in the south‐eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Surveys have shown that the grazing value of veld in the south‐eastern Transvaal is well below the estimated potential. Extension efforts aimed at rectifying the situation have been unsuccessful in that most recommendations have not been acceptable to producers. An...
  9. Long-term effects of conservation practices on the nitrogen fertility of a soil cropped annually to wheat

    Long-term effects of conservation practices on the nitrogen fertility of a soil cropped annually to wheat

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Sustainable farming in the semi-arid interior of South Africa requires the adoption of conservation practices to maintain and, if possible, increase soil fertility. The effects of some such practices on the nitrogen fertility of a hydromorphic sandy clay loam soil...
