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.”

Kovsie fencers dominate the Free State Fencing Closed Competition

Willem Brink and Wanda Verster fenced their hearts out at Free State Closed Competition, winning gold medals in the men’s and women’s category, respectively. These University of the Free State students dominated opponents from the Vrystaat Amateur Skerm Klub (VASK).

Fencers from the VASK retaliated bravely in defense of their honour on Saturday 12 September 2015, with Jurgen Schroder taking home a Silver medal. His team mates, Ruan Coetzee-Schroder and Shaeffer Georgiou, shared the Bronze medal. A winning performance placed VASK’s Danielle Ceronio and Stella Heyns in the Bronze realm.  Kovsie Fencing’s Kayla de Gouveid shared the spot with Stella as a bronze recipient.

It was a clash of the titans as 27 participants formed opposing teams. The University of the Free State (UFS) team, who hosted the competition, showed the guests no sign of mercy as they triumphed.

Wanda was impressed by the UFS’s performance. “The students performed very well, especially considering that most of them started fencing just this year.”

“Willem Brink, who finished with gold, started fencing in 2012.  He finished with a Bronze medal at the Free State Closed competition held earlier, in May 2015 The first fencer to reach 15 wins,” said the Kovsie Fencing representative.

The club will represent our university at the University of Pretoria (TUKS) Open where fencers from the entire country will compete on 25 and 26 September 2015.  The club is also preparing for the University Sports South Africa (USSA) tournament and the Limpopo Open that take place in November and December, respectively. These competitions serve to pave the way for the July 2016 nationals, where Kovsies hope to make their mark as champions.
