  1. Temperate forest dynamics and carbon storage: a 26-year case study from Orange Kloof Forest, Cape Peninsula, South Africa

    Temperate forest dynamics and carbon storage: a 26-year case study from Orange Kloof Forest, Cape Peninsula, South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Temperate forests are globally important carbon stores that are, in the face of recent improvements in their conservation, likely to increase their storage capacity in the future. Despite this, these ecosystems are poorly understood, especially over longer time periods. To...
  2. Insect Damage to Timbers from the Indigenous Forests—Preliminary Results

    Item type: Journal Article • Journal: South African Forestry Journal
    Logs crosscut in the indigenous forests of the southern Cape were inspected for insect damage. The main timber species were Ocotea bullata, Podocarpus latifolius, P. falcatus, Rapanea melanophloeos, Olea capensis subsp. macrocarpa, Platylophus trifoliatus and the naturalised exotic Acacia melanoxylon...
  3. Decline and Mortality of <em>Ocotea bullata</em> Trees in the Southern Cape Forests

    Item type: Journal Article • Journal: South African Forestry Journal
    Dying trees of Ocotea bullata (Lauraceae) occurred in small groups in certain areas in the medium-moist forests of the southern Cape. Crown health declined significantly (P > 0,01) in the dying groups, but this was not the general trend for...
  4. Distribution, Size and Ownership of Forests in the Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    Indigenous forest of the southern Cape as delimited on 1:50 000 maps was analysed for distribution, size and ownership in six landscape zones: mountains, foothill, coastal platform, river valley, coastal scarp and dunes. I tested the hypothesis that forest distribution...
  5. Inventory of Indigenous Forest and Woodland in Southern Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    An inventory is an important component of a series of activities to ensure the sustained use of natural forest and woodland resources. Three levels of inventories are considered: national level to determine general forest policy: regional level to provide a...
  6. Regeneration Patterns in Planted and Natural Forest Stands Near Knysna, Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    The Diepwalle Arboretum was established in 1926 and consists of a cultivated and uncultivated section. The cultivated section consists of pure stands while the uncultivated section contains both pure and mixed stands. In the cultivated section the understorey vegetation was...
  7. Root Systems of Some Southern Cape Indigenous Forest Trees

    Item type: Journal Article • Journal: South African Forestry Journal
    Root system form of forest trees were investigated and classified in the southern Cape indigenous forests. Windfalls of some of the dominant canopy species were inspected. Root systems were opened up by mechanical excavations. Tree species displayed the following general...
  8. Disjunctions and Distribution Limits of Forest Species in the Southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    A total of 206 species reach their distribution limits within the southern Cape forests, or have disjunct distributions within this area and wider distributions outside. Biological variables (growth form, dispersal type) and habitat variables (forest type, moisture tolerance) are not...
  9. Root-shoot Growth Periodicity in <em>Ocotea bullata</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Periodicity in leaf fall, and in the growth of roots and shoots of Ocotea bullata was studied. Leaf fall of canopy trees was measured to establish the natural phenological pattern of mature trees. Shoot growth was measured on potted plants...
  10. Floristic and Structural Composition of Wonderwoud Forest in the Wolkberg, North-Eastern Transvaal

    Item type: Journal Article • Journal: South African Forestry Journal
    The closed, evergreen forest of 450 ha was studied by means of a survey of 55 circular plots of 0,04 ha, distributed in a grid pattern. TWINSPAN classification separated the forest into four stand types: Olea capensis macrocarpa—Xymalos monospora—Syzygium gerrardii...
