Tucked deep in the prehistoric heart of the Barberton Makhonjwa Mountains World Heritage Site, the Mountainlands Nature Reserve is not just a protected area, but it is a living, breathing story of geology, biodiversity, and renewal. Through its partnership with the Spirit Wildlife Foundation (SWF), Mountainlands is shaping a new chapter, one where wildlife, landscapes, and local communities thrive together in a carefully balanced ecosystem.
A visionary legacy
The story of Mountainlands begins in 1985, when conservation efforts were first initiated in the Barberton region. But it was Nico Oosthuizen, whose foresight and commitment brought the reserve into being. As his family acquired farms in the area, Nico recognised the conservation value of the neighbouring properties and initiated talks with public stakeholders, including the then Mpumalanga Parks Board and the Lomshiyo Community Trust.
In 2000, a perimeter game fence unified privately owned and state land into a consolidated 18,000-hectare reserve. This marked the beginning of one of South Africa’s most innovative conservation models—a Community-Public-Private Partnership operating at the landscape scale.
“The strength of Mountainlands lies in its scale and collaboration,” says Oosthuizen. “We’ve brought together diverse owners, priorities, and philosophies into a single conservation-driven entity.”
Biodiversity of global significance
Set within the Barberton Greenstone Belt, Mountainlands is situated atop some of the oldest exposed rocks on Earth, dating back approximately 3.6 billion years. These ancient formations are not only geological marvels but also underpin one of southern Africa’s most botanically rich regions, second only to the Cape Fynbos.
This richness is no accident. The reserve hosts the Barberton Centre of Plant Endemism, a unique microclimate nurturing plant species found nowhere else on Earth. Serpentine soils, high in toxic metals, have produced flora specially adapted to survive, many of them still being discovered and documented today. The diversity does not end with plants. The reserve’s clean, perennial streams, mountainous terrain, and mosaic of habitats support countless species, from giraffes to three endemic butterflies whose entire ecosystems exist within areas smaller than a soccer field.
“Mountainlands is not just a reserve,” says Oosthuizen. “It’s a biodiversity archive, a climate refuge, and a sanctuary for species—some known, some yet to be discovered.”
