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.”

SRC Arts and Culture speaks up
2015-03-17

"Stagedoor was an absolute success," says fourth-year medical student, Stefan van der Westhuizen and SRC member for arts and culture.  

 

"I've always been a diverse person and exposed myself to many things."

 

Raised in Vanderbijlpark near Johannesburg, Stefan has always had a passion for arts and culture.

 

"It's a platform where students express so much. Stagedoor is where you can see students express their commentary on what is happening on campus and feel like it’s almost a safe zone."

 

Stefan’s year on the SRC brought about a new format to rotations. Residences paired with each other, while the new 'outdoor' interactions made it possible for residence and off-campus students to interact with rotations.

 

"I was most proud of the rotations that took place even at the Agricultural Building. There was some great interaction," he said.

 

Stefan said the idea was to fix things.

 

“Not much had changed with Stagedoor when I got into office, even ticket sales were decreasing. I wanted to get students amped about it again."

 

A different element of Stagedoor 'outdoor' was to try to get spontaneity, and to try to get away from residences doing the same plays, but get them out of their comfort spot.

 

“When we heard the results, we lit up with excitement because we didn't have the usual winners,” Stefan said.
