My main interests are in obtaining a better understanding of where plants get their resources and how this affects vegetation structure. In this regard I am particularly interested in the processes that define the boundaries between different vegetation types. I am also interested in the anthropogenic effect on the environment as I believe that people have affected the environment for many thousands of years.
The focus of my research is in two systems, savannas and winter rainfall shrublands. My two main research areas are in the savannas of the Kruger National Park and the winter rainfall shrublands of the Cedarberg and Cape Peninsula. I believe that my research within these reserves should be aligned with the interests and questions identified by reserve management and should inform the management of reserves.
Outside of my research my interests are in Mountains and Mountaineering specialising in high-grade rock-climbing. I have been on a number of climbing expeditions to Australia, America, Britain, Cameroon, France, Germany, India, Italy, Kenya, Lesotho, Malaysia, Malawi, Mali, Morocco, Namibia, Nepal, Thailand, and Zimbabwe. I enjoy making mountaineering videos and in this respect have worked on a number focusing on the mountains of Africa. I have also worked closely with the Table Mountain National Park in popularizing the Park.
