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.”

Two Kovsies in SA Netball team for World Student Games

Two students from the University of the Free State (UFS), Lauren-Lee Christians and Karla Mostert, were selected for the South African Universities Netball team.

The team, with eight Proteas in its ranks, will be in action at the World Student Games in Miami, USA, from 13 to 17 July 2016.

Among the criteria for selection is that participants should not be older than 27 years in 2016, and they should have been students last year.

The South Africans, who came in second during the inaugural tournament in Cape Town four years ago, will be difficult to beat this time. A total of 12 countries will compete for the title of student champions.

Mostert part of previous successful team

Mostert was one of five Kovsies playing for this team in 2012, when South Africa lost 49-53 to Britain in the final. This came after the score was even at the end of regular play.

Mostert was also one of the two best players for the Proteas at the World Cup last year. Christians just missed out, and had to be content with being a non-travelling substitute after she became the 12th Protea of the UFS earlier in 2015.

Four from UFS in Cucsa squad

Meanwhile, four other of their teammates - Rieze Straeuli, Tanya Mostert, Kgomotso Mamburu, and Alicia Puren - were included in a provisional squad of 15 players to compete for the South African student team at the Cucsa Games (Southern African Student Games). This squad will soon be reduced to the 12 players who will represent their country in Bulawayo, Zimbabwe, from 1 to 6 August.

No Protea can be selected for this student team. A fifth Kovsie, the goal shooter, Dénielle van der Merwe, was also selected for the initial squad, but had to withdraw due to a serious leg injury.
