  1. Indigenous High Forests in the Transvaal with Special Reference to Inventory and Monitoring Systems

    Item type: Journal Article • Journal: South African Forestry Journal
    The indigenous forests in the Transvaal comprise a total area of 35 385 ha, of which 18 088 ha or 51% are situated on State forest land. The forests are found mainly along the Drakensberg escarpment and, to a lesser...
  2. Conservation Developments in South African Forestry

    Item type: Journal Article • Journal: South African Forestry Journal
    The historical development of environmental conservational activities within the South African Forestry Industry is followed, and the changing emphasis from the conservation of the remaining indigenous forests (pre-1900) to water conservation, to natural assets and unplanted areas is highlighted. The...
  3. Habitat use by indigenous grazing ungulates in relation to sward structure and veld condition

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The objective of the study was to examine the relationships between the habitat requirements of different wild ungulate species, sward structure and veld condition. Veld condition score was correlated with sward height: habitats with high condition scores were dominated by...
  4. Development of a technique for assessing veld condition in the Kruger National Park using key grass species

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A technique based on key grass species was developed for assessing veld condition in the Kruger National Park in terms of its potential to produce grass forage for consumption by herbivores and fine fuels for veld burning. Fourteen grass species...
  5. Are multi‐paddock grazing systems economically justifiable?

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The financial implications of few‐ and multi‐paddock systems were modelled by a discounted cash flow analysis with the (discounted) present value as the dependent variable, and number of paddocks, farm run‐down time, time horizon and discount rate as the independent...
  6. Range monitoring in South Africa: A broad perspective

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Range monitoring is defined, in the context of this paper, as regular surveillance to establish whether properties of the range are changing. The objective of such monitoring is therefore to establish whether temporal changes are taking place in response to...
  7. Soil-water conservation as affected by primary tillage practices

    Soil-water conservation as affected by primary tillage practices

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    An investigation of water conservation as affected by different primary tillage methods was conducted on a soil of the Doveton series (fine-loamy, mixed, thermic family of Rhodic Paleudults), where a direct sampling technique was used to monitor the soil-water profiles...
  8. Soil-water conservation as affected by primary tillage practices

    Soil-water conservation as affected by primary tillage practices

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    An investigation of water conservation as affected by different primary tillage methods was conducted on a soil of the Doveton series (fine-loamy, mixed, thermic family of Rhodic Paleudults), where a direct sampling technique was used to monitor the soil-water profiles...
  9. The effect of reduced tillage on soil organic carbon

    The effect of reduced tillage on soil organic carbon

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The organic carbon contents of the 0–15-cm and 15–30-cm layers of conventionally tilled, stubble-mulched and no-tilled soils were compared. Samples from four localities in the Transvaal and Orange Free State were analyzed for organic C by means of two methods...
  10. The effect of various tillage methods on soil and water losses from maize lands

    The effect of various tillage methods on soil and water losses from maize lands

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Natural runoff plots on which maize was produced were laid out at Cedara on a well-drained clay loam Doveton soil and showed, over a six-year period, the benefits to be gained from adopting conservation tillage practices. The four tillage and...
