  1. Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Calculating stocking rates for game ranches: Substitution ratios for use in the Mopani Veld

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Determination of carrying capacity for mixed‐ or multi‐species grazing systems is complex. Commonly, each species is compared to the standard large stock unit (LSU) used in conventional agriculture. However, this approach does not allow for ecological separation, and thus overlooks...
  2. Use of Ecological Site Classification in the Prediction of Forest Productivity and Response to Fertilisation

    Item type: Journal Article • Journal: South African Forestry Journal
    The principals of biogeoclimatic ecosystem classification were used to stratify sites supporting immature stands of coastal Douglas-fir. The resulting strata were shown to represent unique segments of regional gradients of available soil moisture and nutrients. Regression models indicated strong relationships...
  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. 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...
  5. An alternative approach to veld condition assessment in the non‐grassveld regions of South Africa

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Traditional veld condition assessment methods score veld either in terms of its ‘state of health’ or its value for a specific land‐use objective. This is problematic and we propose that ‘veld condition’ should simply be a descriptive index, devoid of...
  6. A LIMNOLOGICAL PROFILE OF THE UPPER OKAVANGO DELTA AT LOW WATER LEVEL

    A LIMNOLOGICAL PROFILE OF THE UPPER OKAVANGO DELTA AT LOW WATER LEVEL

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Selected limnological attributes of the Okavango Delta panhandle were measured during a brief summer survey of “open-water” habitats extending from the permanent mainstream channel, through contiguous off-channel lagoons and still backwaters, to seasonally isolated floodplain lagoon and temporary pool biotopes...
  7. A LIMNOLOGICAL SYNOPSIS OF BHANGAZI SOUTH, A DYSTROPHIC COASTAL LAKE IN THE GREATER ST LUCIA WETLAND PARK (KWAZULU/NATAL), WITH COMMENTS ON ITS CONSERVATION VALUE.

    A LIMNOLOGICAL SYNOPSIS OF BHANGAZI SOUTH, A DYSTROPHIC COASTAL LAKE IN THE GREATER ST LUCIA WETLAND PARK (KWAZULU/NATAL), WITH COMMENTS ON ITS CONSERVATION VALUE.

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Base-line limnological and biological data are given for Lake Bhangazi South, a small lake on the coastal plain of Kwazulu-Natal, South Africa. This shallow (Zmax < 6 m), subtropical lake is a warm and seemingly continuously polymictic system, but experiences...
  8. COMMENTS ON THE WATER QUALITY OF THE MHLATHUZE ESTUARY IN RELATION TO DETERMINING THE ECOLOGICAL INTEGRITY CLASS

    COMMENTS ON THE WATER QUALITY OF THE MHLATHUZE ESTUARY IN RELATION TO DETERMINING THE ECOLOGICAL INTEGRITY CLASS

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Water quality forms an integral component of the determination of the Ecological Reserve of a water resource. This paper presents the available historical and current information on the water quality of the Mhlathuze estuary, The data were assessed in order...
  9. A REVIEW OF THE MACROBENTHIC FAUNA OF THE MHLATHUZE ESTUARY: SETTING THE ECOLOGICAL RESERVE

    A REVIEW OF THE MACROBENTHIC FAUNA OF THE MHLATHUZE ESTUARY: SETTING THE ECOLOGICAL RESERVE

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    This paper reviews historical and current ecological information on macrobenthos from the Mhlathuze Estuary before and after development of the Richards Bay Harbour. The fauna is described in terms of the potential influence of a change in freshwater inflow to...
  10. The challenge of integrated rangeland monitoring: synthesis address

    The challenge of integrated rangeland monitoring: synthesis address

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The need to balance biodiversity conservation with sustainable development, though widely agreed upon, is elusive in practice. Human societies are increasingly disconnected from the ecosystems which support them. The loosening connection and growing scientific acceptance that ecosystems are complex, dynamic,...
