    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Projected increases in Africa's human population over the next 40 years point to further, large-scale conversion of natural habitats into farmland, with far-reaching consequences for raptor species, some of which are now largely restricted to protected areas (PAs). To assess...

    Plantation Forestry in South Africa and its Impact on Biodiversity

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Empirical studies and other evidence indicate that tree farming has had a marked impact on biodiversity in some areas of South Africa, Plant and animal species have been made extinct or are threatened by afforestation, and afforestation is largely responsible...
  7. A Comparison of the kraft pulp properties of P. <em>elliottii</em> and the <em>P. elliottii</em> x <em>P. caribaea</em> var. <em>hondurensis</em> hybrid grown in Queensland, Australia

    A Comparison of the kraft pulp properties of P. <em>elliottii</em> and the <em>P. elliottii</em> x <em>P. caribaea</em> var. <em>hondurensis</em> hybrid grown in Queensland, Australia

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The interspecific hybrid between P. elliottii var. elliottii and P. caribaea var. hondurensis has recently been accepted for planting operationally as an alternative to P. elliottii by Sappi in South Africa. Some concerns have been expressed as to the suitability...
  8. Growth and fibre yield of <em>Pinus patula</em> and <em>Pinus elliottii</em> pulpwood plantations at high altitude in Mpumalanga

    Growth and fibre yield of <em>Pinus patula</em> and <em>Pinus elliottii</em> pulpwood plantations at high altitude in Mpumalanga

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The demand for pine pulpwood in the Mpumalanga province approaches two million tonnes per annum. To meet processor demand for low cost wood, it is important to maximise timber productivity per planted hectare. Selection of species for a site can...
  9. Kraft Pulping Quality of <em>Pinus taeda</em> Reaction Wood

    Item type: Journal Article • Journal: South African Forestry Journal
    Reaction wood, apparently associated with an inherited susceptibility and coincident severe black pine aphid infestations (Cinara cronartii) in 16-year-old, improved Pinus taeda gave low yields of pulp with very poor strength characteristics. This type of wood is considered unacceptable for...
