BSc Hons (UCT) MSc (NMMU)



After completing her schooling in Johannesburg, Hayley moved to Cape Town to pursue a BSc and BSc Honours in Zoology at the University of Cape Town. She then travelled abroad to spend a year working on conversation projects in Central America. Inspired by the conservation efforts she saw in the tropics, she returned to South Africa and began working on a private game reserve in the Eastern Cape, where she developed and ran a student wildlife programme. Whilst working on the reserve, Hayley became interested in the ways in which private protected areas could contribute to conservation in South Africa. She was particularly interested in the gaps in understanding regarding how to effectively manage these areas for conservation. She therefore undertook an MSc through Nelson Mandela Metropolitan University, looking at cheetah feeding ecology and developing a model for determining the number of cheetah that a reserve could sustain, given its available prey community.

After finishing her MSc in 2013, Hayley moved back to Cape Town to continue with research regarding private protected areas. She is therefore undertaking a PhD, supervised by Prof Graeme Cumming, exploring social-ecological dynamics on private protected areas in South Africa. Private protected areas conserve over double the land area in South Africa than do statutory protected areas. It is therefore important to ask the question “Can we rely on private protected areas to conserve biodiversity into the future?” Answering this question requires an improved understanding of their economic objectives, their approach to ecological management and what the interactions between these factors can tell us about private protected area resilience in contributing to biodiversity conservation.
