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.”

Our university honoured our top athletic achievers at the annual Kovsie Sports Star Awards that took place on 23 October 2014.

Maryka Holtzhausen and Wayde van Niekerk were named Sportswoman and Sportsman of the Year respectively.

Holtzhausen captained the Protea netball team that participated in a host of test series and championships. These included:
•    a test series against Trinidad & Tobago and England in October last year,
•    the Fast Five World Series in Auckland, New Zealand during November 2013, as well as
•    the Commonwealth Games in Glasgow this year.

Van Niekerk, in turn, set a new SA record in the 400 m of 44.38 at the Diamond League meeting in New York, USA during June 2014. As a member of the Protea team who participated in the Commonwealth Games in Glasgow earlier this year, he won the silver medal in the 400 m sprint. In August 2014, Van Niekerk clinched the silver medal in the 400 m at the CAA Senior African Athletics Championship in Morocco. He also formed part of the CAA African Athletics team who competed in the intercontinental cup meeting during September 2014. The team won gold in the 4x400 m relay at this event.

The Junior Sportsperson for 2014 is Driaan Bruwer. He was a member of the SA U/19 cricket team that won the Junior World Cup this year.

Our university’s sports stars were honoured in the following five categories:

•    Sportsman and Sportswoman of the Year. Everyone that represented South Africa at a senior level was eligible for the title. The winners each received a trophy and each sportsman and sportswomen in this category were honoured with a medal.
•    Junior Sportsperson of the Year. The winner received a trophy.
•    Sports stars that represented South Africa at senior and junior level. The achievers received certificates.
•    Sports stars that represented the UFS in the national student teams. These sports stars also received certificates.
•    Certificates were also awarded to the KovsieSport Club sports stars.
