  1. Aspects of the seed ecology of Acacia karroo in the Eastern Cape, South Africa

    Aspects of the seed ecology of Acacia karroo in the Eastern Cape, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Seed ecology may play a role in the widespread increase of Acacia karroo in savanna and grassland. Accordingly, fecundity, predation, mortality by fire, dispersal by livestock, and seed longevity were studied. Seed production per tree (P of pod production, pods...
  2. Does high-density stocking affect perennial forbs in mesic grassland?

    Does high-density stocking affect perennial forbs in mesic grassland?

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Livestock production is an appropriate land use for mainstreaming biodiversity conservation, but little is known about the impact of grazing strategies on forbs that contribute most species, in grasslands. This study compared the effects of high-density, short-duration stocking (HDG) with...
  3. What are the long-term effects of high-density, short-duration stocking on the soils and vegetation of mesic grassland in South Africa?

    What are the long-term effects of high-density, short-duration stocking on the soils and vegetation of mesic grassland in South Africa?

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    High-density, short-duration stocking (HDG) is gaining popularity amongst farmers in the South African mesic grasslands, but little is known about its potential impact on natural resources. Using a fence-line contrast approach, this study compared the long-term effects of HDG with...
  4. Grond‐ en afloopverlies bepalings vanaf natuurlike veld, met behulp van ‘n reënvalnabootser

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    ‘n Oorhoofse roterende reënvalnabootser is gebruik om die sediment‐ en afloopverliese vanaf natuurlike veld in verskillende suksessiestadia en teen verskillende hellings te bepaal.
  5. Influence of rainfall and grazing on the compositional change of the herbaceous layer of a sandveld savanna

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The influence of heavy grazing by cattle for three years, and of rainfall interception for one year, on the herbaceous composition of a sandveld savanna in Gazankulu was investigated. The composition and the abundance of the predominant species changed substantially,...
  6. Patterns of plant selection by grazing cattle in two savanna grasslands: A plant's eye view

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The amount of grazing experienced by individual tufts of the most abundant perennial grasses of two Transvaal savannas was monitored at regular intervals for two growing seasons. In general, Setaria incrassata and Themeda triandra were heavily grazed, Bothriochloa insculpla and...
