PhD thesis: Cheetah conservation in a changing landscape -  Habitat, conflict and connectivity in Southern Africa (2025)

This thesis investigates the ecological and social factors affecting cheetah conservation in Southern Africa's changing landscapes, focusing on free-roaming and managed-reserve cheetah populations. Using species distribution models and multi-source cheetah presence data, it identifies where suitable habitat overlaps and mismatches with protected areas and predicts future changes under climate and land-use scenarios. Results show that most suitable cheetah habitat lies outside of formal reserves and that future connectivity and habitat stability may decline with rapid human expansion and climate shifts.
Empirical research, including surveys from over 260 landholders and extensive camera trap studies, reveals moderate conflict between cheetah and farmers compared to other predators. Cheetah show remarkable flexibility in activity patterns and site use, modifying their behaviour to avoid humans and competing carnivores, which is key for coexistence in multi-use landscapes. The thesis also evaluates the readiness of captive cheetah for rewilding, finding that targeted behavioural training is needed to improve reintroduction success.

A major recommendation is for conservation efforts to prioritize landscape connectivity and corridors beyond protected areas, working closely with private landowners and communities to balance human-wildlife conflict and biodiversity protection. This integrated approach offers the best chance for securing the future of the cheetah across southern Africa in an era of climate change and fragmented habitats.
