Growth, flowering and recruitment of shrubs in grazed and in protected rangeland in the arid Karoo, South Africa

  title={Growth, flowering and recruitment of shrubs in grazed and in protected rangeland in the arid Karoo, South Africa},
  author={Sue J. Milton},
A three-year study involving 1300 marked shrubs of three species differing in palatability to sheep provided evidence that changes in the demographic structure of shrub populations in arid rangelands are a function of seed availability. Sheep reduced canopy size and flowering of their preferred forage species but had no effect on survivorship of seedlings or established plants during the study. Although annual turnover in all populations was low (<6%), abundant recent recruitment of non-forage… CONTINUE READING
