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.”

Kovsies triumph in Free State hockey
2014-08-05

During the first weekend of August 2014, the University of the Free State (UFS) was once again crowned as the Free State hockey champions.

In the finals of the Free State championships, the Kovsies’ women’s team beat the Reds (Kovsies 2nd team) by 10-1. This is the ninth consecutive year that our women’s team walk away as champions. It was clear from the start that Kovsies wouldn’t be satisfied by anything less than a win and a courageous Reds team was unable to cover all the gaps.

After being at the helm for three years, the Kovsies’ coach, Jacques du Toit, announced his retirement after the game. During his coaching term, Kovsies had their best performances since the 1984 season – when the Kovsie women won the University Sports South Africa (USSA) tournament.

Since 2012, the Kovsies’ women’s team went from strength to strength. For the first time since 1993, they ended among the top four teams in the USSA tournament that year. In the following year they repeated this performance and also achieved a bronze during the first Varsity Sport Hockey tournament for women.

Kovsies’ men’s hockey team was also crowned as champions in the Free State championships for the 12th consecutive year. We won against the Central University of Technology in the finals by 9-2. This year our team of champions also succeeded in breaking a medal drought of 30 years in the USSA tournament. We defeated the team from the University of Johannesburg to gain a bronze.

This year, Kovsies was also the only university that managed to win two medals at the USSA hockey tournament and can rightfully claim the title as best tertiary hockey club in the country.
