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.”

They are amongst the top 15 percent of academic achievers at the university, and have been afforded the opportunity to travel abroad and meet with leading people in their fields of study.

Kovsie students Michael van Niekerk, Siobhan Canavan, Mpoi Makhetha and Cebolenkosi Sokhela, all members of the Golden Key International Honour Society, will travel to the USA and China. This trip is part of the International Scholar Laureate Program (ISLP) to learn how their career fields are practiced in another part of the world. The students are part of a select group of outstanding university students from across the world who will be given access to people, places and global perspectives in fields such as business, engineering, medicine, nursing, diplomacy and international relations.

Michael, a fourth-year MBChB student and SRC member of our Bloemfontein Campus, and Cebolenkosi, a third-year BSc Microbiology student will visit Washington, Philadelphia and New York in the USA. As part of the medicine delegation of the programme, they will visit clinics and hospitals to see how their study fields are practiced. Michael’s trip includes a visit to Johns Hopkins University in Baltimore, where he will meet representatives of the National Institute of Health, the largest source of funding for medical research in the world. He will also visit Harvard University in Massachusetts.

Mpoi, a third-year BSc Human Molecular Biology student, also forms part of the medicine delegation but will travel to China. "We will be exploring the ancient ways of healing versus the modern medical practices, exploring the medical systems of the country and meeting doctors and professors, visiting the rural areas, and of course, touring the best parts of China,” she said.

Siobhan, a third-year Media Studies and Journalism student, is part of the diplomacy and international relations delegation who will visit Beijing, Xi'an and Shanghai in China. "To me it's such an honour to be part of this programme,” she said. “It will give me the platform to not only represent who I am, but also my university and the values that the university has instilled in me. It allows me to be a part of something great that will benefit me in the end."
