I hold an MSc degree (pass cum laude) in forestry and currently completed lecturing silviculture for the final year students enrolled at Nelson Mandela University within the forestry course. With my great communication and interpersonal skills, I have taught various key concepts relating to silviculture. As a result, I have gained comprehensive knowledge of how various forestry treatments (that occurs within both silviculture and harvesting) impacts rotation length tree growth responses (survival, overall growth (yield) and uniformity) within forestry. My working as a supervisor for a silvicultural contractor also prepared me to ensure that both land and re-establishment budget is implemented timeous and according to company BOP standards. I was also responsible to track and monitor planting, ensuring all incoming seedling trees are accounted for and planted infield according to BOP practices. During my post graduate studies, I have been part of the team responsible to find alternative safe herbicides (that would remain certified according to FSC standards) to replace paraquat, which was used during the preparation of tracer belts. The outcomes of this work were suitable herbicide, which may be used as an alternative to paraquat. As part of my PhD whereby I am currently developing an herbicide risk model, whereby I created an herbicide-use database for the commercial forestry industry to catalogue and keep track of herbicide usage throughout South Africa. The aim of the herbicide risk model is to find alternative silvicultural treatments to vegetation management (that does not solely relay on the use of herbicides) and compare with those treatments that rely heavily on the use of herbicides (such as full vegetation management). The reason for this risk model is due to the current worldwide trend of reducing the reliance on herbicide use, it is essential to source alternative treatments that would provide similar growth response to those whereby herbicide is used. Although I may not be well established as a forester, my theoretical knowledge and implementation thereof curbs this shortcoming.
