After matriculating, Jonathan pursued a career for 10 years in the electronics field of data processing and microprocessors in the Johannesburg area. During this period his passion for nature grew as a hobby to a point where he decided to give up the city in favour of a profession in wildlife research.
Jonathan went on to complete a B.Sc (Zoology and botany) through the University of South Africa (UNISA) while working as a field guide in the Sabi Sand Game Reserve. Thereafter he graduated with a B.Sc Honours before completing a six year study on the Behavioural Ecology of the Cape Pangolin for his M.Sc degree, which he obtained in 1996. Jonathan then conducted ecological research in the Sabi Sand reserve focusing on the effect of habitat manipulation on grazing suitability for plains game in conjunction with elephant impact on the vegetation. Through these studies Jonathan was appointed Ecologist for the Sabi Sand Game Reserve from 2003 to 2010. Jonathan accepted the post of Research Ecologist for Welgevonden Game Reserve in November 2011.
