  1. Vertical distribution of living mangrove foraminifera from KwaZulu-Natal, South Africa

    Vertical distribution of living mangrove foraminifera from KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Modern foraminiferal assemblage zones can be used to reconstruct palaeo sea levels when applied to fossil foraminifera down a sediment core. Previous intertidal foraminiferal studies have predominantly focused on assemblages in surface sediments (0–1 cm), with the rationale that surface...
  2. 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...
  3. 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...
  4. Floristic and Structural Composition of Hanglip Forest in the Soutpansberg, Northern Transvaal

    Item type: Journal Article • Journal: South African Forestry Journal
    The closed, evergreen forest of 363 ha was sampled by means of 62 circular plots of 0,04 ha, distributed in a grid pattern. TWINSPAN classification separated the forest into regrowth forest with two forest types, and mature forest with four...
  5. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    Part 2 of the series of papers dealing with the regeneration ofPinus radiata in the Southern Cape discusses the effect of the experimental treatments on the distribution of nutrient elements, more particularly to estimate the impact of treatments on changes...
  6. Modelling Diameter and Height Distributions through Dispersion Statistics in Even-aged Pine Plantations

    Item type: Journal Article • Journal: South African Forestry Journal
    Diameter and height distribution recovery, in combination with standlevel projection modelling, is generally used in Southern Africa for predicting growth and yield in even-aged pine plantations. A different approach for modelling diameter and height distributions for five pine species commercially...
  7. The Blackwood Group System: its relevance for sustainable forest management in the southern Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    The invasion status of Australian blackwood, Acacia melanoxylon, is assessed against its value as a commercial tree in the southern Cape forests. The species was introduced from Australian rain forests and planted extensively in the southern Cape forests since 1909...
  8. Variation in important pasture grasses: I. Morphological and geographical variation

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Seven species are important pasture grasses throughout the western Transvaal, Orange Free State, northern Cape and Natal. Taxonomically, each is a widely distributed species complex with a range of morphological variants and many ecotypes. The local forms well suited to...
  9. Leaf silicification in grasses — A review

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Silica is absorbed from the soil by many grasses in an active or passive manner depending upon the species involved. It is carried upwards in the transpiration stream and deposited throughout the plant where it polymerizes to form amorphous silica...
  10. Influence of phosphatic fertilization on the yield and chemical composition of grass pasture

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    While the distribution of P fertilizer had an insignificant influence on the DM production of a grass pasture over a three‐year period, the level of both N and P was highly significant. Growth patterns were unaffected by any of the...
