  1. The Hydrological Effects of a Wildfire in a Eucalypt Afforested Catchment

    Item type: Journal Article • Journal: South African Forestry Journal
    A high-intensity wildfire through a humid, upland catchment which was partially afforested to Eucalyptus fastigata, markedly increased stormflows and caused high soil losses off the afforested slopes. Total streamflow yield was unchanged but baseflow was reduced after the fire. The...
  2. Analysis of Stable Isotopes of Xylem Water from Plantation Trees in E. Transvaal and Zululand Indicate they Utilised Ground water During Drought of 1992

    Item type: Journal Article • Journal: South African Forestry Journal
    We investigated the stable isotopic signature of xylem sap of mature plantation trees and the associated ground water at sites in Zululand and E. Transvaal. The survey took place mainly during the drought of 1992. Results indicated a range of...
  3. Are Pine Plantations “Inhospitable Seas” around Remnant Native Habitat within South-western Cape Forestry Areas?

    Item type: Journal Article • Journal: South African Forestry Journal
    Some areas of forestry estates, including unplantable ones, may be zoned and managed for nature conservation. This paper is an analysis of the results of studies of plants, birds and small mammals at Jonkershoek, Stellenbosch, to determine whether pine plantations...
  4. The nutritive value, yield and botanical composition of irrigated pastures as influenced by nitrogen fertilizing<sup>1</sup>

    The nutritive value, yield and botanical composition of irrigated pastures as influenced by nitrogen fertilizing<sup>1</sup>

    The performances of grass and grass/legume swards at three levels of nitrogen were compared under irrigation over a three‐year period. The swards were grazed by dairy cows and the influence of nitrogen on dry matter yield, protein content, protein yield...
  5. The Effects of Riparian Clearing and Clearfelling of an Indigenous Forest on Streamflow, Stormflow and Water Quality

    Item type: Journal Article • Journal: South African Forestry Journal
    The paired catchment method was used to measure the effects of riparian zone clearing and clearfelling on streamflow, stormflows and water quality. The forested riparian zone of a 39,6 ha, humid Northern Province catchment, amounting to 10 % of the...
  6. Pros and cons of eliminating veld burning

    Pros and cons of eliminating veld burning

    Fire has been a factor of the environment in Africa since time immemorial and it is often caused by natural agencies such as lightning. It is maintained that there is much prejudice against veld burning, often ill‐founded. Fire has caused...
  7. Response of tall grassveld to different intensities, seasons and frequencies of clipping

    Response of tall grassveld to different intensities, seasons and frequencies of clipping

    The seasonal production of herbage by Tall. Grassveld declined with increased frequency of cutting in summer. Even a single summer cutting treatment reduced yields compared with no summer cutting. The effect of such a single cutting treatment varied, however, with...
