  1. 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,...
  2. Characteristics of fire behaviour in the montane grasslands of natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Fire behaviour characteristics were investigated in the montane grasslands of the Natal Drakensberg. The behaviour of experimental fires was measured together with the accompanying biotic and abiotic conditions. Estimates of heat yield, mass of available fuel and forward rate of...
  3. The effect of different fire treatments on the population structure and density of the Marula, <em>Sclerocarya birrea</em> (A. Rich.) subsp. <em>caffra</em> (Sond.) <em>kokwaro</em> (Kokwaro &amp; Gillet 1980) in the Kruger National Park

    The effect of different fire treatments on the population structure and density of the Marula, <em>Sclerocarya birrea</em> (A. Rich.) subsp. <em>caffra</em> (Sond.) <em>kokwaro</em> (Kokwaro &amp; Gillet 1980) in the Kruger National Park

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    To determine the influence of frequency and season of burn on the growth structure and density of Sclerocarya birrea, six replicated fire treatments of the experimental burning plot trial were surveyed in the Sclerocarya birrea / Acacia nigrescens savanna of...
  4. Is carry-over of grass biomass between years important in determining savanna fire regimes?

    Is carry-over of grass biomass between years important in determining savanna fire regimes?

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    We show that the size of areas burned in three southern African parks is dominated by the amount of rainfall in the immediately preceding summer. Considering mean rainfall from two years previous changes r2 values by <20%. We interpret this...
  5. 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...
  6. Post fire indicators of fire intensity at indigenous forest margins in the southern Cape, South Africa

    Post fire indicators of fire intensity at indigenous forest margins in the southern Cape, South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The aim of this study was to identify post fire indicators of fire intensity at indigenous forest margins in the southern Cape. Three sites in the southern Cape were subjectively chosen in recently burnt areas to represent areas of varying...
  7. Distribution, Size and Ownership of Forests in the Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    Indigenous forest of the southern Cape as delimited on 1:50 000 maps was analysed for distribution, size and ownership in six landscape zones: mountains, foothill, coastal platform, river valley, coastal scarp and dunes. I tested the hypothesis that forest distribution...
  8. The Hydrological Effects of a Wildfire in a Eucalypt Afforested Catchment

    Item type: Journal Article • Journal: South African Forestry Journal
    A high-intensity wildfire through a humid, upland catchment which was partially afforested to Eucalyptus fastigata, markedly increased stormflows and caused high soil losses off the afforested slopes. Total streamflow yield was unchanged but baseflow was reduced after the fire. The...
  9. Commercial Forestry on Signal Hill and Lion's Head, Cape Town

    Item type: Journal Article • Journal: South African Forestry Journal
    The history of afforestation with alien tree species on Signal Hill and Lion's Head, which form part of the Table Mountain Nature Reserve, Cape Town, was reconstructed. The natural vegetation comprises mostly West Coast Renosterveld which is considered the most...
  10. Effects of season of burn on shrub survival, regeneration and structure in the Natal Drakensberg

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four shrub species which tend to invade unburnt grassland were studied in fieldā€burning trials at Cathedral Peak in the Natal Drakensberg.
