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.”

Kovsie student represents SA at Sudirman Cup in China
2009-05-26

The South African National Badminton Team recently represented South Africa at the Sudirman Cup in Guangzhou, China. The Sudirman Cup is the World Mixed-team Badminton Championships, which take place every two years.

Annari Viljoen, a Kovsie student and the brothers Chris and Roelof Dednam, former Kovsie students, were included in team that represented South Africa at the championships.

In the first match of the tournament, the Dednam brothers were the only victors when they won the mens doubles and defeated Paul Jefferson Vivas and Ronel Estanislao of the Philippines with 2117 and 2112.

In their second match, the South African team beat Luxembourg 41. In the mixed doubles the Dednams defeated Joe Michels and Yann Mellers with 2111 and 219 and in the womens doubles Michelle Edwards and Annari beat their opponents Anne Schumacher and Annick Weides with 1321 and 2224.

The South African team competed against Turkey in their third match and won 32, only losing the singles event. In the mens doubles the Dednams defeated Mehmet Tural and Ali Kaya with 2116 and 2113 and in the womens doubles Michelle Edwards and Annari beat Derya Calimbay and Oznur Caliskan with 2220 and 2117.

In the final group match team South Africa competed against Switzerland and lost 41 with only the mixed doubles pair of Dorian James and Annari winning their match against Anthony Dumartheray and Sabrina Jacquet with 1221, 2422 and 2119.
