The Magaliesberg is a UNESCO Biosphere Reserve balancing ecological restoration with pressures from urban growth, agriculture, and mining. Its ridges host unique biodiversity, cultural heritage, and water catchments, while supporting more than two million nearby residents. Challenges include alien plant invasions, ridge degradation, and poorly managed urban expansion. Restoration focuses on ridge protection, alien clearing, and sustainable tourism management. Economic opportunities lie in heritage tourism, ridge offsets, and conservation-linked jobs. The goal is to maintain the Magaliesberg as a biodiversity refuge in the heart of South Africa’s urban-industrial core.
