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 centenary reaches a peak
2004-10-04

The University of the Free State’s (UFS) centenary celebrations will reach a peak next week when various functions will be presented on campus.

On Tuesday 12 October 2004 the Centenary Complex, the new prestige entertainment venue of the UFS, will be officially opened. The complex is situated on the terrain of the old Reitz dining hall and will be utilised as reception and socialising area for UFS management, staff and alumni. The DF Malherbe House forms part of this complex.

The festivities will continue the next day ( Wednesday 13 October 2004) with the premiere of a documentary programme – commissioned by the UFS as part of its centenary celebrations - about the life and legacy of King Moshoeshoe, the Basotho leader of the nineteenth century. The documentary will focus on his role in reconciliation, nation-building and bringing about peace in this region. The producer of this insightful work is the well-known journalist Mr Max du Preez. The documentary will be screened on SABC 2 later this year.

On Thursday 14 October 2004 a special honorary doctorate graduation ceremony will take place in front of the UFS’s main building. During this event 12 honorary doctorates will be awarded to a diverse group of outstanding South Africans and international experts.

The honorary doctorates will be awarded to: Me Antjie Krog, Prof Jakes Gerwel, Mr Karel Schoeman, Dr Frederick van Zyl Slabbert, Prof Saleem Badat, Dr Khotso Mokhele, Prof Robert Bringle, Prof Leo Quayle, Prof Jack de Wet, Prof Kerneels Nel (postuum), Prof Boelie Wessels and Prof Jaap Steyn.

This group of honorary doctorates is the last in a total of 18 which will be honored during the UFS centenary year.

The next day, Friday 15 October 2004 , more than 100 centenary medals will be awarded to current staff, former staff and alumni.
