  1. Whole-tree sap flow responses to soil water and weather variables for <em>Pinus radiata</em> and three indigenous species in a southern afrotemperate forest region

    Whole-tree sap flow responses to soil water and weather variables for <em>Pinus radiata</em> and three indigenous species in a southern afrotemperate forest region

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    In a water-scarce country such as South Africa, timber and fibre production often stands in conflict with catchment water yields. The optimal provision of both is sought. Forest hydrological experiments improve our understanding of the soil–plant–atmosphere continuum and facilitate the...
  2. 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...
  3. Towards a method of assessing the veld condition of the valley bushveld in the Eastern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Currently, no technique is available for assessing the condition of Valley Bushveld in the Eastern Cape. The objective of this investigation was to develop a method of scoring bushveld according to its productive condition. It was established, through principal component...
  4. Inter‐related floristic changes associated with different long‐term grazing treatments in Sourish Mixed Bushveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Eight camps, grazed annually during different seasons by steers, were surveyed. Herbaceous species were grouped into Decreaser and Increaser categories according to their reaction to grazing. The Increaser IIa (light overgrazing) and IIb (moderate overgrazing) herbaceous species were the most...
  5. Secondary succession in the Mopani veld of the Limpopo Valley, South Africa

    Secondary succession in the Mopani veld of the Limpopo Valley, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The long-term establishment sequences of the herbaceous and woody component of the Mopani veld of the Limpopo Valley were studied and documented. Based on vegetation surveys conducted at three enclosed sites at the Messina Experimental Farm during the period 1964...
  6. Grass species composition, yield and quality under and outside tree crowns in a semi‐arid rangeland in south‐western Zimbabwe

    Grass species composition, yield and quality under and outside tree crowns in a semi‐arid rangeland in south‐western Zimbabwe

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    A two‐year study was conducted in lightly grazed areas of Matopos Research Station, Zimbabwe, to evaluate the impact of widely spaced trees on understorey grass composition, yield and quality. The study trees were Terminalia sericea and Acacia karroo. Ordination techniques...
  7. Translocation of marbled African lungfish, <em>Protopterus aethiopicus</em> (Telostei: Protopteridae), and its fishery in Lake Baringo, Kenya

    Translocation of marbled African lungfish, <em>Protopterus aethiopicus</em> (Telostei: Protopteridae), and its fishery in Lake Baringo, Kenya

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The translocation of the marbled African lungfish Protopterus aethiopicus into Lake Baringo created a new fishery for the local community, who capture them primarily in a bottom-set long line fishery. Its introduction, development and current fishery status in the lake...
  8. <em>Myosotella myosotis</em> (Mollusca: Ellobiidae) — an overlooked, but well-established introduced species in South Africa

    <em>Myosotella myosotis</em> (Mollusca: Ellobiidae) — an overlooked, but well-established introduced species in South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Myosotella myosotis is shown to be a well-established alien species in South Africa. Discovered in Port Elizabeth more than 100 years ago, it was initially thought to be indigenous and was described under two different names, but subsequent taxonomic work...
  9. Restoring bare patches in the Nama-Karoo of South Africa

    Restoring bare patches in the Nama-Karoo of South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Often veld degrades to a point beyond which vegetation cover, plant density and species composition do not recover despite the removal of the grazing impact. In such cases restoration interventions become necessary to assist with the re-establishment of vegetation. The...
  10. Allelopathic effects of invasive <em>Eucalyptus camaldulensis</em> on germination and early growth of four native species in the Western Cape, South Africa

    Allelopathic effects of invasive <em>Eucalyptus camaldulensis</em> on germination and early growth of four native species in the Western Cape, South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Eucalyptus camaldulensis Dehnh. (red river gum; Myrtaceae) is an invasive tree in riparian habitats of the Western Cape, South Africa, where it replaces indigenous vegetation and affects ecosystem functioning. These invasions lead to changes in river geomorphology and reduction in...
