  1. Cable Yarding in Southern Africa: An Analysis of its Productivity and Possible Procedure for its Improvement

    Item type: Journal Article • Journal: South African Forestry Journal
    The demand for timber in southern Africa is increasing and this is resulting in the afforestation of areas which require cable yarding when harvested. The demand for cable yarders, essentially fixed skylines, is therefore increasing rapidly. Stress is being placed...
  2. 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...
  3. Grond‐ en afloopverlies bepalings vanaf natuurlike veld, met behulp van ‘n reënvalnabootser

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Oorhoofse roterende reënvalnabootser is gebruik om die sediment‐ en afloopverliese vanaf natuurlike veld in verskillende suksessiestadia en teen verskillende hellings te bepaal.
  4. Effect of slope and plant cover on run‐off, soil loss and water use efficiency of natural veld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Run‐off and soil loss were monitored from a climax, subclimax and pioneer veld, each on a 5,9%, 4,1% and 2,1% slope, by means of a rainfall simulator on a Valsrivier soil form. With rainfall intensity, soil moisture content at the...
  5. Considerations on the sustainability and environmental impact of intensive pastures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Intensive pastures form an important component of livestock production systems in South Africa. The sustainability and environmental impact of intensive pastures via their effects on soil properties and nutrient fluxes vary considerably depending on the systems adopted. Soil organic C...
  6. Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Six levels of maize stover, expressed as percentage ground cover (0–75%) were compared under a rainfall simulator to assess the effect of surface residues on infiltration and soil loss on a clay loam soil with a 3,5% slope. Increasing the...
  7. Application of Empirical Soil Loss Models in southern Africa: a review

    Application of Empirical Soil Loss Models in southern Africa: a review

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Empirical soil loss models are relatively simple and have been applied in many parts of the world. The application of the Soil Loss Estimation Model for Southern Africa (SLEMSA), the Universal Soil Loss Equation (USLE) and the Revised Universal Soil...
  8. Evaluation of soil conservation measures on a highly erodible soil in the Free State province, South Africa

    Evaluation of soil conservation measures on a highly erodible soil in the Free State province, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Soil erosion is a problem in South Africa, and is exacerbated by poor land use practices and erodible soils. Several methods are available to address the problem and a runoff trial was conducted over four rainfall seasons on an erodible,...
  9. THF DISTRIBUTION AND STATUS OF <em>KNERIA AURICULATA</em> (PELLEGRIN)(PISCES: KNERIIDAE) IN THE TRANSVAAL

    THF DISTRIBUTION AND STATUS OF <em>KNERIA AURICULATA</em> (PELLEGRIN)(PISCES: KNERIIDAE) IN THE TRANSVAAL

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The distribution of Kneria auriculata in the upper reaches of the Crocodile River (Incomati River System) was determined. Knevia auriculata shows a preference for cold mountain streams with calm pools. Five isolated populations exist in such streams. Although no accurate...
  10. RATE OF EROSION IN THE CATCHMENT OF THE BULBERGFONTEIN DAM NEAR REDDERSBURG IN THE ORANGE FREE STATE

    RATE OF EROSION IN THE CATCHMENT OF THE BULBERGFONTEIN DAM NEAR REDDERSBURG IN THE ORANGE FREE STATE

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The volume of sediment in the Bulbergfontein Dam was computed after mapping the area of the dam and ascertaining the depth of the sediment by digging and augering. The watershed of the impoundment had been delimited by means of aerial...
