Size matters: A new large-scale renosterveld landscape protected
The Oudekraalskop conservation easement secures Endangered renosterveld, rare species and important ecological corridors in perpetuity.
Every piece of renosterveld matters. But when a large, connected landscape joins the Overberg Renosterveld Trust’s Conservation Easement Programme, it marks an especially important conservation win.
The newly signed conservation easement, Oudekraalskop, brings Endangered Eastern Rûens Shale Renosterveld and Rûens Silcrete Renosterveld under protection in perpetuity – securing another key fragment of one of the world’s most threatened ecosystems.
According to Conservation Manager Grant Forbes, the Steenkamp family, who own the property, are conservation-minded landowners who recognise the value of protecting biodiversity on their farm.
“They really take ownership of what they’ve got here, and they see the value of the contribution they’re making towards conservation of such a unique and threatened ecosystem. We are very proud to be working with them and look forward to a long relationship where we together conserve a representative area of renosterveld from this region.”
Threatened with extinction
Monitoring by the Overberg Renosterveld Trust team recorded 225 plant species on the property, with more than 10% classified as threatened with extinction.
Some of the special species recorded include:
• Hesperantha muirii (Endangered)
• Ruellia pilosa (Vulnerable)
• Oedera garnotii (Vulnerable)
• Liparia striata (Endangered)
Grant says that the property is particularly important because of the quartz patches found within the landscape.
“Eastern Rûens Shale Renosterveld is quite variable as you move from west to east. However, you’re likely to find these unique quartz patches in these landscapes, and they house a very unique group of species that depend on these areas for survival.”

Why corridors are key
Another remarkable feature of Oudekraalskop is its intact watercourses – an unusual characteristic for the Overberg. Rivers and wetlands not only support biodiversity, but also connect renosterveld fragments, creating important ecological corridors for species movement.
These systems also provide ecosystem services, helping to attenuate flood damage and support landscape resilience.
Where wildlife thrive
Beyond plant diversity, the property supports a wide range of wildlife. Camera trap surveys have confirmed the presence of several mammals, including:
- Aardwolf
- Cape Grysbok
- Grey Rhebok (Threatened)
Pollinators also rely on these connected landscapes for survival. Species recorded on the farm include the Cape Honeybee, Needlenose Fly and various butterflies such as the Common Blue.

Less than 5% of renosterveld remains today. Much of what survives exists on privately owned farmland.

Protected fragments of renosterveld across the Overberg are starting to form something far more meaningful than isolated patches.
An invisible crisis in renosterveld
The tiny relationships holding everything together. Together with fire, these animals drove the structure of the renosterveld ecosystem and the constantly changing ratios of shrubs to grasses.
One of the world’s most threatened ecosystems
“Many people just don’t realise how threatened renosterveld is,” says Grant. “It’s one of the most endangered ecosystems in South Africa – and possibly on the planet – with less than 5% remaining. Of that, very few fragments are large and connected like Oudekraalskop.”
The value of partnerships
The Overberg Renosterveld Trust’s Conservation Easement Programme enables landowners to protect biodiversity while continuing to farm.
“An easement is essentially a conservation servitude registered on the property, where the landowner sets aside an area for conservation,” says Grant.
“Here conservation and agriculture work together to protect biodiversity and maintain the ecological health of the region, ensuring that renosterveld is protected and managed well into the future.”
The partnership also includes incredible donors who support the conservation and restoration work of the ORT. This includes WWF South Africa, the Mapula Trust, the Ford Wildlife Foundation, Engie, the World Land Trust and the Hans Hoheisen Charitable Trust.
