I have a BSc in Zoology and Botany (UNISA), Hons BSc in Environmental Science (NWU), MSc in Environmental Science (NWU) which resulted in the publication below. I am currently busy with my PhD part time (Botany, Nelson Mandela University) specialising in freshwater diatoms of the Karoo.

I am part of the AEON team conducting baseline research for the Karoo Shale Gas Project. The working title for this project is ‘Diatoms as an ‘early warning’ monitoring tool for surface and groundwater contamination: towards a water baseline for the Karoo”. 

My research

As a farmer’s wife I have experience in many aspects of veld management, erosion control and rehabilitation as well as correct stocking of mixed feeders.

I have conducted non scientific presentations (listed below) and continue to do so, on request, to groups of all ages on the importance and conservation of the four smaller cats species in the Karoo.   I have worked with game farms, game reserves and national parks with their release of these species in the correct habitats. I have worked with national and international media for programmes on these species. I have many years experience in keeping these cats in captivity including the notoriously difficult Black-footed cat (Felis nigripes).  The CCT has received 3 grants from the National Lotteries Distribution Trust Fund.
