All mountains around the world have native and non-native species that are expanding their ranges quite dramatically; however, little research has been conducted towards understanding the long-term redistribution of species and the effects of global change on biodiversity.


The Afromontane Research Unit (ARU) on the University of the Free State Qwaqwa Campus – as part of the Mountain Invasion Research Network – has secured a two-year EU Horizon 2020 project under the Department of Science and Innovation, which will be looking at the mechanisms underlying the success and impact of range-expanding species on biodiversity and ecosystem functioning.

On Monday 19 July 2021, the ARU took a few of its researchers on a scenic helicopter ride to the summit of the Drakensberg for an alpine field-experiment site inspection of the Mont-aux-Sources peak, one of the highest sections of the Drakensberg range. This site has been identified for the project which the research unit will be leading on mountain research.

ARU Director, Dr Ralph Clark, said the project would explore the effects of global change, biological invasions (when species invade new geographic regions), as well as climate and land-use change. He said experiments were needed to explore the various possibilities and to test the extent to which species respond to experimental treatments. The project would therefore be conducting experiments for two years using open-top chambers – causing an increase in temperature of 3 or 4 degrees to what you find naturally – on plant species from lower down to the top of the mountain, to see how they function. “This will give us an idea of whether they will be able to survive in global warming scenarios. If temperatures get warmer, we might start seeing a lot of plants up here that we wouldn’t otherwise find here.”

Dr Clark said little is known about the long-term monitoring of species distribution and the effects of global change. Implementing the project in the Maloti-Drakensberg alpine area will therefore put the area in the global mountain research arena. The elevational gradient in the Maloti-Drakensberg Mountains provides space to explore the key processes underlying the variation in species elevation with climate change. “One of the things we don’t know much about are alpine systems. We are hoping to establish a long-term alpine research site and try to add as many studies as we can. The more science we can bring up here, the more we can know about mountain life. What happens on mountains has a lot of impact on social dynamics.

“This project is looking to see what is driving range expansion. Every mountain has its own context. In the Swiss alpine, fires are not a big factor, but fires are one of the biggest factors on our mountains. Some of our native and non-native species are therefore fire-driven, so as fire increases, you might have them spreading faster.”

New SRC Sport talks about campus pride
2014-10-21

Media Studies and Journalism student, Dominique de Gouveia, can attest to the fact that you need to take all the small steps before you make the giant leap.

As Residence Committee member for Sport since her first year, Dominique found the transition to the Student Representative Council (SRC) merely a case of now putting on the striped blazer. Having worked closely with Lourika Hugo, previous SRC Sport, there was not really much that she had to take grasp of.

“Our varsity has almost the same sport fixtures every year, so once you understand it, it should not be that difficult to follow through,” says Dominique confidently.

“You need to set goals in order to achieve them. I quickly realised that this is what I want to do. Sport is very big on our campus among the students and in my term I want other channels to realise the importance of sport.”

“The motto of previous SRC Sport, Tshepo Moli, was ‘transformation in sport’, which can indeed make a social impact on our varsity.”

“Through sport, our varsity can take pride in showing diversity.”

The variety of sports Dominique enjoys playing and watching, shows just how much she really loves what she is doing.

“My favourite sports have to be soccer and squash. But after watching the Varsity Netball this season, it made me wish that I had learnt how to play netball as far back as high school.”
