  • Aligning design with science : tree grids and rings in the landscape 
    Stoffberg, G.H.; Van Rooyen, Margaretha W.; Groeneveld, Hendrik T.; Van der Linde, Michael J. (Mike) (International Society for Horticultural Science, 2016)
    Tree grids and tree rings pose certain challenges to the designer of landscapes especially designing hard landscapes such as pavements, parking areas and roadsides. One challenge is insufficient knowledge of lateral ...
  • The effect of herbivores and humans on the Sand Forest species of Maputaland, northern KwaZulu-Natal, South Africa 
    Gaugris, Jerome Yves; Van Rooyen, Margaretha W. (Springer, 2011)
    Sand Forest in the Maputaland region of KwaZulu-Natal in South Africa is deemed the most valuable, but also probably the most complex vegetation type of this part of the Maputaland-Pondoland-Albany hotspot of biodiversity. ...
  • Evaluating patterns of wood use for building construction in Maputaland, South Africa 
    Gaugris, Jerome Yves; Van Rooyen, Margaretha W. (Southern African Wildlife Management Association, 2009-04)
    A questionnaire survey was conducted to evaluate the level of wood utilization for house building in the community of Manqakulane in Maputaland, northern KwaZulu-Natal, South Africa, in 2003. The questionnaire's aims were ...
  • Evidence for a geochemical origin of the mysterious circles in the Pro-Namib desert 
    Naude, Yvette; Van Rooyen, Margaretha W.; Rohwer, Egmont Richard (Elsevier, 2011-12)
    The origin of the so-called “fairy circles” has not yet been established. Carbon monoxide (as an indicator of a natural gas microseep) was monitored inside and outside of the selected fairy circles in the Namib, Namibia, ...
  • Landscapes in the Kalahari Gemsbok National Park, South Africa 
    Van Rooyen, Margaretha W.; Van Rooyen, Noel; Bothma, Jacobus du P.; Van Den Berg, Hendrik M. (South African National Parks, 2008)
    A landscape map of the Kalahari Gemsbok National Park is presented. Mapping is at a finer scale than previous vegetation and habitat maps for the same area. The landscapes were grouped into seven large classes and a total ...
  • A spatial and temporal analysis of Sand Forest tree assemblages in Maputaland, South Africa 
    Gaugris, Jerome Yves; Van Rooyen, Margaretha W. (Southern African Wildlife Management Association, 2008-10)
    Maputaland is a centre of plant endemism, within the Maputaland-Pondoland-Albany hotspot of biodiversity shared by Mozambique and South Africa. The Sand Forest vegetation is the most valuable vegetation type in this region ...
  • Springbok behaviour as affected by environmental conditions in the Kalahari 
    Stapelberg, F. Hein; Van Rooyen, Margaretha W.; Bothma, Jacobus du P.; Van der Linde, Michael J. (Mike); Groeneveld, Hendrik T. (South African National Parks, 2008)
    Springbok behavioural ecology in the Kalahari was examined with the use of public questionnaires and field forms. Springbok favoured grass and forbs overall more than shrubs and trees, but diet selection was influenced by ...
  • Woody vegetation utilisation in Tembe Elephant Park, Kwazulu-Natal, South Africa 
    Gaugris, Jerome Yves; Vasicek, Caroline A.; Van Rooyen, Margaretha W. (Canadian Center of Science and Education, 2014)
    A survey of woody plant species utilisation by large (excluding elephants), medium and small browsers,man and “natural damage”, was conducted in nine vegetation units of Tembe Elephant Park, KwaZulu-Natal, South Africa. ...
