Glynis’s main research interests are in fire history, ecology and people and the use of interdisciplinary research in addressing savanna-woodland fire management in southern Africa. Her PhD (2018), supervised by Associate Professor Lindsey Gillson, titled ‘The role of humans, climate and vegetation in the complex fire regimes of north-east Namibia’ focused on understanding the historical and present-day social-ecological determinants of fire in Bwabwata National Park. She used an integrated approach of historical data, and social surveys in combination with remote sensing and geographical information system (GIS) analyses to understand the fire regime dynamics in a savanna landscape over a period of 16 years (2000 – 2015).

Her current post-doctoral research builds upon her PhD thesis in Bwabwata National Park and investigates the extent of vegetation change over decadal - centennial time periods with the use of historical aerial photographs and Landsat imagery. This first phase of the project involves examining possible changes associated with a transition in fire management policy from suppression to early burning strategies in the park. The second component involves modelling past and future land use and fire management scenarios. This research is part of a wider multi-disciplinary project investigating long-term vegetation and fire dynamics that includes several other students using repeat photography and palaeo-ecological datasets in collaboration Associate Professor Lindsey Gillson and the University of Witwatersrand (WITS).

Glynis has a B.Sc. (Hons) in Environmental Science from Rhodes University, and an M.Sc in Conservation Biology from the Fitzpatrick Institute of African Ornithology at the University of Cape Town. Between her studies, she worked in the ecological field in South Africa, Peru, Botswana, Namibia, and Tanzania. Professional experiences include work as a conservation ecologist, field guiding in South Africa, wild-life research and monitoring, environmental consulting specializing in arid-zone ecological restoration and environmental assessments in Namibia. Her professional research interests are founded upon an established interest in understanding the complex interactions between people, conservation policies and ecology in savanna environments under the threat of global environmental change.

Key research interests:
People and biodiversity conservation in African developing countries, climate change, fire and savanna –woodland ecology; history, social-ecological interactions between climate, land use, people (indigenous groups, NGOs and Government); remote sensing; GIS; rural livelihood sustainability; conservation policies; interdisciplinary synthesis i.e. pyrogeography; modelling social-ecological-fire regime coupling scenarios; applied management, and science communication.
