  1. 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...
  2. Refinement of a model describing forage production, animal production and profitability as a function of bush density in the false thornveld of the eastern cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    An existing model describing the influence of Aeacia karroo density on forage production, animal production and profitability is reviewed and amended to introduce recent research results.
  3. The expected response <em>of acacia karroo</em> hayne to moisture stress and defoliation

    The expected response <em>of acacia karroo</em> hayne to moisture stress and defoliation

    The generalised growth of woody species and their response to defoliation is presented to provide a conceptual background for an examination of the growth of Acacia karroo and its response to defoliation. Particular attention is paid to water stress and...
  4. Replacing <em>stipa trichotoma</em> nees (nassella) in the Eastern Cape

    Replacing <em>stipa trichotoma</em> nees (nassella) in the Eastern Cape

    This paper describes a trial in which various grasses, with and without nitrogenous fertilization, and legumes were screened for their ability to replace nassella in non‐arable areas. The results indicate that a vigorous canopy cover played an important role in...
  5. <em>Euonurus muticus</em> in the dohne sourveld

    <em>Euonurus muticus</em> in the dohne sourveld

    A range of grazing and non‐grazing defoliation treatments were appiied to Dohne Sourveld in order to record their effect on the presence and vigour of Elionurus muticus. Frequent heavy utilisation reduced the vigour but not the presence of E. muticus...
  6. Herbaceous species preference by cattle in the false thornveld of the Eastern Cape

    Herbaceous species preference by cattle in the false thornveld of the Eastern Cape

    Herbaceous species preference by cattle was studied at two sites of different botanical composition in the False Thornveld of the Eastern Cape. Of the grasses under observation, Themeda triandra was the most preferred species. Animals continued to graze selectively even...
  7. Monitoring of veld burns using satellite imagery

    Monitoring of veld burns using satellite imagery

    Using simple image interpretation procedures, veld burning from June to October 1981 was monitored over 19 394 100 ha of the eastern agricultural regions of South Africa. From 1 096 burns, an area of 412 826 ha burnt veld was...

    The expected response of <em>acacia karroo</em> hayne to moisture stress and defoliation

    The generalised growth of woody species and their response to defoliation is presented to provide a conceptual background for an examination of the growth of Acacia karroo and its response to defoliation. Particular attention is paid to water stress and...
  9. The role of <em>acacia karroo</em> in the false thornveld of the eastern cape <em>die rol van</em> acacia karroo <em>in die skyn‐doring veld van die oos‐kaap</em>

    The role of <em>acacia karroo</em> in the false thornveld of the eastern cape <em>die rol van</em> acacia karroo <em>in die skyn‐doring veld van die oos‐kaap</em>

    An investigation was undertaken to determine the relationship between tree density and grass production, tree density and overall feed production and between tree density and animal production. It was found that grass production does not decrease linearly with increasing tree...
