  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. Socio-economic determinants of smallholder plantation sizes in Ghana and options to encourage reforestation

    Socio-economic determinants of smallholder plantation sizes in Ghana and options to encourage reforestation

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Reforestation, particularly in the tropics, is of crucial importance for the environment as well as society. However, small planting areas and low participation of smallholder farmers in tree planting programmes often obstruct realisation of set planting area targets. In this...
  3. 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...
  4. 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...
  5. 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...
  6. 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...
  7. 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...
  8. An investigation into the establishment of indigenous trees on treated mine residue soils in South Africa

    An investigation into the establishment of indigenous trees on treated mine residue soils in South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Mine residue soils have been the cause of barren landscapes and due to its toxic nature, these soils have proved difficult in establishing any form of vegetation. A selection of indigenous tree species mainly used for the establishment of indigenous...
  9. Afromontane forest avifauna of the eastern Soutpansberg mountain range, Northern Province, South Africa

    Afromontane forest avifauna of the eastern Soutpansberg mountain range, Northern Province, South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The Soutpansberg forests form the northern limit of indigenous forest in South Africa, Commercial afforestation occurs at high altitudes whereas crops and orchards are planted at lower altitudes. A study of five protected afromontane forests in the eastern Soutpansberg identified...
  10. The distribution and feeding ecology of the characid <em>Brycinus sadleri</em> in Lake Nabugabo, Uganda: implications for persistence with Nile perch (<em>Lates niloticus</em>)

    The distribution and feeding ecology of the characid <em>Brycinus sadleri</em> in Lake Nabugabo, Uganda: implications for persistence with Nile perch (<em>Lates niloticus</em>)

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Coincident with a rapid increase in numbers of introduced predatory Nile perch (Lates niloticus) in lakes Victoria, Kyoga, and Nabugabo of East Africa was a dramatic decline in populations of many native fishes. However, a few species, including the characid...
