Dr Falko Buschke says the iconic sandstone cliffs of the eastern Free State are key to protecting wild plants and animals from climate change.
The iconic sandstone cliffs of the eastern Free State are often the focus of paintings and postcards. Now, new research shows they also protect wild plants and animals from climate change. This finding is the outcome of a collaborative research effort by the University of the Free State (UFS); BirdLife South Africa; the Vrije Universiteit Brussel and KU Leuven, Belgium, which has recently been published in the journal Biological Conservation.

Mountains key for climate change mitigation

The study, led by Dr Falko Buschke from the Centre for Environmental Management UFS, used satellite data from NASA to track the ecological effects of wet and dry seasons, including the record drought of 2015/16. This showed how vegetation on the cool and moist mountain slopes was less affected by dry spells.

The complex physical terrain allows moisture to accumulate in the shaded parts of the south-facing slopes and ravines. This creates cool and moist habitats for plants and animals that wouldn’t survive in the rest of the hotter and drier landscape.

The team also discovered that these positive effects of mountains do not end at the foot of the mountain, but extend at least 500m into the flatter lowlands. “Presumably because water and nutrients accumulate in these surrounding buffers due to run-off,” says Dr Buschke.

Butterflies find safety on mountains

In addition to their high-tech analysis of the area, the team also relied on old-fashioned fieldwork to monitor butterflies over two years. “The data showed us how these insects find safety on mountains during harsh climate conditions and can then recolonise the rest of the landscape after conditions improve,” explains Dr Buschke. “This gives us clues on the best way to protect nature,” he adds. 

This study took place in the Rooiberge-Riemland Key Biodiversity Area (KBA), an area significant for maintaining global biodiversity. Several species of insects, reptiles, birds and mammals here occur nowhere else on earth. “If they disappear here, they will go extinct from the whole planet forever,” says Dr Falko Buschke. 

Despite its ecological significance, most of the area is covered by commercial farmland. So, the next stage of the project is exploring ways of protecting these important habitats while ensuring that farmers can continue producing food and supporting rural livelihoods. 

“Farmers hold the key to preserving biodiversity,” says Dr Buschke, “so conservation scientists need to work closely with them to ensure that we protect species for future generations.”

Paul Whitehead never thought the small business he started in his hostel room at the University of the Free State (UFS) in Huis Abraham Fischer on the Bloemfontein Campus would develop into something of magnitude.

Paul, who completed his Honours degree in Architecture in 2015 at the UFS, is currently taking a gap year due to the rapid growth of his business. Major John started back in December 2012, with Love Warrior becoming Paul’s first outlet. In 2014 Paul started manufacturing his first series of timber bow ties and after that, sales started booming.

Supplier to 16 outlets in South Africa

“We currently supply 16 outlets throughout South Africa with a range of products such as timber bow ties, genuine leather suspenders and concrete and timber desk lamps, as well as other leather products,” Paul says.

He says that a new range of nine timber bow ties is launched every four months. “The timber is recycled and the fabric is handpicked from around the country to ensure quality, thus the bow ties are hand-crafted and unique,” Paul says.

Trust your gut feeling and believe in yourself

His main goal with the timber bow ties is to expand while the unique quality of the product is not compromised. “We are also in a process of expanding the range of our products in the exclusive market.”

Paul attributes his success to delivering excellent service to people who appreciate his pride and joy, his Major John collection. He encourages future entrepreneurs to listen to others’ advice, but to trust their own gut feeling and always believe in themselves.
