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.”

Meet the person behind the title – your new FaceOfFacebook
2015-04-29

Kovsies #FaceOfFacebook was born three years ago out of a need to engage with students, and become a virtual friend. Auditions are held every year to choose the new ‘face’ representing the UFS on Facebook. The successful candidate holds the title as #FaceOfFacebook for the next 12 months, attending events, and filming short video clips to post on our Facebook page.

 

The votes have been counted, and we have a winner. After much excitement and a close contest, Nompumelelo Maseko (whose name, fittingly, means ‘success’) emerged victorious from the top six contestants selected by our panel of judges. We sat down with the soft-spoken Mpumi – as her friends call her – to get a sense of the person who will be our ambassador for the next year.

 

What is your field of study, and how far along are you?

I am studying for a BSc degree in Genetics, and I’m currently in my second year. I have a particular interest in the forensic sciences, which fascinate me!

 

Are you originally from Bloemfontein?

No, I am originally from Pretoria.

 

How is it that you ended up here, studying at the UFS?

Before leaving school, I applied to various universities, but my desires and ambitions brought me here.

 

How do you find your residence?

Akasia ladies are big on sisterhood, very supportive. Res life is very enjoyable.

 

What do you hope to accomplish during your term as the #FaceOfFacebook?

I would like to help people become aware of what is taking place on campus. There are many opportunities to be more engaged with what is happening at the varsity. For instance, there are still many people who don’t really know what the #FaceOfFacebook is, and I would like to help inform them about it.

 

What is your motivation in your studies, in taking part in this contest, and in life?

I am intrigued by the function of life forms, the differences that exist at a cellular level.
For this competition, I fed off my love of people, even though I am shy. I also enjoy presenting.


I have my parents to thank as my motivation, as well as meeting and engaging with people. I find that I achieve a broader perspective when I don’t restrict myself to my own opinions, but strive to be open to differing views.

 

Nompumelelo will be appearing in one of her first Facebook videos shortly, so be sure to keep an eye on our Facebook page.
