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.”

Music was always something this singing sensation wanted to do from a very early age.

Sonet du Plessis, more famously known by her stage name, Hailey Clark, is a third-year BA Drama and Theatre Arts student at the University of the Free State (UFS). Her electronic pop debut album, titled Deurmekaar, was finally launched after a year of hard work and sacrifice.

Success in English and Afrikaans

Hailey, whose album features Afrikaans and English songs, says her music is influenced and inspired by a variety of local sounds and artists. “Dirk van der Westhuizen and Refentse – a new and upcoming artist – are two of the locals I look up to,” she says.

Reaching success at such a young age is the result of setting goals and achieving them. “Success is when you grow as a person and an artist in your music. You need to enjoy every moment of what you do and share it with other people,” Hailey says.

Future music producer and actress

With a bright future ahead of her, Hailey wants to become a full-time musician, but also wants to focus on acting, especially in films. “I want to perform as much as possible and hopefully become a music producer. I also have plans to do some acting as well.”

For all those who dream of becoming a musician, it’s hard work, Hailey says. “You have to know it is something you want to do and you have to commit to it. If it is what you want, keep focused and surround yourself with positive and encouraging people.”
