Dr Rina (C. C.) Grant-Biggs

Dr Rina (C.C.) Grant -Biggs qualified as a veterinarian from Onderstepoort, University of Pretoria in 1974. During the thirteen years that she was employed at the veterinary laboratory in Windhoek (Namibia), she was responsible for the diagnosis of  plant poisonings and nutritional deficiencies. She developed faecal analysis as a diagnostic tool to determine the nutrient status of domestic and wild herbivores. She completed a  DVSc in physiology (equivalent to a PhD) focussing on the links between nutritional status and deficiencies of rangeland cattle and the landscapes they were utilizing.

After moving to the Kruger National Park (KNP) she worked as an independent researcher/consultant on how wildlife utilized the landscape (in terms of geology, soil type and vegetation), and the link to their nutritional status.

During this time she worked as the technical advisor for the Sappi Tree Spotting series that was aimed at helping novices to start identifying the common trees using various approaches such as distinguishing features and their location in the landscape.  This series covered the whole of South Africa.

She was appointed as Programme Integrator: Systems Ecology for Scientific Services from 2006 -2014, based in Skukuza in the Kruger National Park.  Her research in science-management links focussed on 1. The effect of elephant on vegetation and the related biodiversity. 2. The utilization of  small scale patches by wild herbivores in a heterogeneous environment.
