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.”

Lizelke Klindt – part of the Kovsie family

 

“To be a Kovsie is awesome.” This is how Lizelke Klindt starts the conversation.

Who is Lizelke?

She is one of our top emerging academics. Expanding on her BSc in Astrophysics, she obtained an honours degree in Physics this year – cum laude – earning her the Dean’s and Senate Medal.

At this year’s Kovsie Open Day on the Bloemfontein Campus, Lizelke beamed across the stage at prospective students and their parents – embodying true Kovsie pride.  

Her academic journey has just begun, though. Lizelke is currently doing her MSc in Astrophysics. Her thesis focuses on the ‘Multi-wavelength Analysis of Unidentified Active Galactic Nuclei in the Fermi 2LAC Catalogue’.

“This will allow me to travel around to collect my own data and will broaden my skill set in order to reduce the various data,” she says.

Her achievements have gone hand in hand with hard work and grapping every opportunity the university has to offer, she admits. She also has a lot of praise for our university for offering research opportunities to graduates in their respective fields.  

“My studies have allowed me to travel a lot and to meet people from all over the world. I have made friends in Germany, Poland, Australia and other European countries.

“And the best part of it all is I get to fly a lot. I absolute love it. And if there was such a thing as a second life, I would definitely be a pilot or hopefully an astronaut. It’s a good feeling to be part of the Kovsie family.”

Lizelke plans to continue onto her PhD in the coming years. And then? She fervently wishes to get a post-doctoral position at the very same university that opened a world to her that she loves passionately. A world she has dreamt of since childhood.
