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.”

UFS opens new Research and UDRAW writing unit

The Library and Information Services Division at the University of the Free State (UFS) recently opened two brand-new facilities in the UFS Sasol Library, which includes a new research unit for postgraduate students as well as a new UDRAW Unit (Unit for the Development of Rhetorical and Academic Writing).

The opening of both units is the culmination of planning that originally started with Ms Huibré Lombard, Acting Director of the division Library and Information Services at the UFS, and Prof. Louis Venter, Head of UDRAW, back in 2005. The facilities were officially opened by the Vice-Rector: Teaching and Learning, Prof. Driekie Hay.

The research centre caters for postgraduate students, specifically for those studying towards a Masters or Doctoral degree at the UFS. The centre will help students by supplying advanced research information and specialised staff to cater for their needs. It will also serve as a quiet environment where students can come and work. The UDRAW facility will help shape the writing of postgraduate students as well as supervisors and also provide classes and consultations to further develop the research language of the students. An added benefit for students is that both services are provided free of charge to registered senior postgraduate students at our university.
