ARU pioneering mountain range-expanding project

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.”

SRC President Njabulo Mwali says that the presence of international students on the Qwaqwa Campus is very welcome as it enables students from all over the world to learn from each other. He was addressing the International Student Council’s welcome function for international students.

“One important area where South African students can learn a lot from international students is hard work. It is an open secret that many of us, as South Africans, are not as persistent as we should be. We give up easily,” he said to an audience of students mainly from Zimbabwe, Kenya, Ethiopia, and Nigeria.

Speaking on behalf of the Rectorate, the Registrar: Systems and Administration, Dr Karen Lazenby, assured international students that the UFS is committed to their emotional and physical wellbeing.

International students face various challenges

“Having been an international student myself, I fully understand your various challenges. If you have any ideas on how we can make your stay here as memorable as possible, please help us to help you,” she said.

Both Drs Elsa Crause and Dipane Hlalele, respectively Campus Vice-Principal: Academic and Research and Acting Campus Vice-Principal: Support Services, congratulated students on choosing the Qwaqwa Campus.

“Our campus will give you many opportunities to reinvent yourself both as a person and a student,” Dr Crause said.

Dr Hlalele added: “International experience is fascinating as it does not only provide different types of knowledge and truth, it also enriches the campus with an African and international footprint.”

The Office of International Affairs also presented its services to students.
