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.”

“To me, this pageant is about empowering young women. It helped me realise my strengths and weaknesses; it taught me how I can overcome my weaknesses and use my strengths to the best of my ability.”

This is exactly what second-year BCom Accounting student Phemelo Lekale sets out to do during her reign as Miss Free State 2017.

Bring about change and make a difference

The Miss Free State pageant aims in assisting young women to reach out to their communities and charities to bring about change. The pageant also aims to make a difference in somebody’s life.

Phemelo, who takes over from last year’s Kovsie winner Mienke van Rooyen, said that she needed to grow and learn as an individual, and that is exactly what the Miss Free State platform gave her.

Excited about the opportunities lying ahead

When the announcement was made, Phemelo was filled with so many mixed emotions she only realised she was the new Miss Free State when Mienke handed over the sash. “It felt like someone was saying ‘yes, I believe in you and the vision that you proposed to bring to the table’.”

Phemelo said she was excited about the opportunities that came with being Miss Free State and the impact that this brand would have on society. “By the end of my reign, I won’t be the same woman I was when I entered and neither will I be the same woman I was when I won the crown.”
