  1. Efficiency of inventory plot patterns in quantitative analysis of vegetation: a case study of tropical woodland and dense forest in Benin

    Efficiency of inventory plot patterns in quantitative analysis of vegetation: a case study of tropical woodland and dense forest in Benin

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The main issue in forest inventory is the reliability of data collected, which depends on the shape and size of inventoried plots. There is also a need for harmonisation of inventoried plot patterns in West Africa. This study focused on...
  2. Stand structure and regeneration of harvested <em>Araucaria araucana–Nothofagus</em> stands in central Chile

    Stand structure and regeneration of harvested <em>Araucaria araucana–Nothofagus</em> stands in central Chile

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    In this study we examined the current structure and regeneration status of mixed Araucaria araucana–Nothofagus spp. stands that had been logged 20 years ago. We measured stand density of saplings, juvenile and adult trees, as well as stand basal area...
  3. The leaf-litter earthworm fauna (Annelida: Oligochaeta) of forests in Limpopo Province, South Africa: diversity, communities and conservation

    The leaf-litter earthworm fauna (Annelida: Oligochaeta) of forests in Limpopo Province, South Africa: diversity, communities and conservation

    Item type: Journal Article • Journal: African Zoology
    A qualitative survey of the leaf-litter earthworm fauna of 11 selected indigenous forests in Limpopo Province, South Africa, was conducted to identify the species present, to describe the communities and to assess the relationship between indigenous and exotic species. A...
  4. Mangrove expansion and population structure at a planted site, East London, South Africa

    Mangrove expansion and population structure at a planted site, East London, South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Avicennia marina (Forrsk.) Vierh. was planted in 1969 at Nahoon Estuary, East London, followed a few years later by the planting of Bruguiera gymnorrhiza (L.) Lam. and Rhizophora mucronata (L.) among the larger A. marina trees. This study tested the...
  5. Seasonal habitat requirements of Lemon Dove (<em>Aplopelia larvata</em>) in coastal forest: camera-trap surveys of a reclusive species

    Seasonal habitat requirements of Lemon Dove (<em>Aplopelia larvata</em>) in coastal forest: camera-trap surveys of a reclusive species

    Item type: Journal Article • Journal: African Zoology
    The modification of natural habitats requires behavioural plasticity, which may be challenging for ‘specialist’ species. Quantifying habitat requirements and behavioural responses of specialists to landscape transformation is thus a priority for baseline data to inform conservation practices. Using camera-trap surveys...
  6. Adjusting Faustmann's Formula for a Dynamic Financial Environment

    Item type: Journal Article • Journal: South African Forestry Journal
    The well-known LEV criterion or Faustmann's formula which evolved in the static financial environment of the nineteenth century is adjusted to take account of the changes in the dynamic financial environment of today. A previous incorrect attempt to adjust LEV...
  7. Financial Decision Criteria and Real Price Changes

    Item type: Journal Article • Journal: South African Forestry Journal
    General price indices such as the Consumer Price Index (CPI) or the Production Price Index (PPI) represent the weighted average of prices of a large number of goods and services. Such price indices therefore cannot accurately measure the changes in...
  8. A New Form of Internal Rate of Return

    Item type: Journal Article • Journal: South African Forestry Journal
    When the Internal Rate for Return (IRR) of a forestry project is calculated by means of traditional methods which ignore real price changes, the IRR for one rotation of the project is identical to the IRR for an infinite series...
  9. Role of Eucalypt Plantations in Timber Supply and Forest Conservation in Sub-Saharan Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    The role of eucalypt plantations in timber supply and forest conservation in Sub-Saharan Africa was investigated. The annual destruction of 11,5 million ha of tropical forest is highlighted, the various causes indicated and the controversy whether fast-growing plantations and woodlots...
  10. Estimated Woody Litterfall in Broadleaved, Evergreen Forest, Southern Cape, South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    A new line-transect technique for monitoring woody litterfall in forests is described. In indigenous, evergreen coastal forest at Harkerville, southern Cape, branches and trees which fell and accumulated across 50 m lengths of twine over a period of seven years,...
