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 Tennis team defends proud USSA record in Cape Town

Duke Munro already has six gold medals from the USSA Tennis Tournament in his cupboard, and the Kovsie Tennis team would wish to bid him farewell in a fitting manner during what will probably be his last tournament in Cape Town.

This year's tournament, taking place from 30 November to 4 December 2015, will probably be Munro's last, since he is completing his Master's degree in Quantity Surveying at the University of the Free State (UFS).

He has competed in the USSA Tournament since 2009, and would like to help his team defend its proud record.

UFS aim for ninth consecutive title

Kovsies have won gold at the USSA Tournament for the last eight years. They are the only team who have been able to win the tournament since the combined format was adopted in 2010. In 2007 and 2008, their Women's team won the tournament, and in 2009, their Men's team.

Kovsies will play in group matches against the Universities of Venda and Wits on 30 November 2015, against the University of Cape Town's (UCT's) second team on 1 December 2015, and against UCT's first team on 2 December 2015. The cross and knockout matches will be played on 3 and 4 December 2015.

Other sporting codes

The Sevens Rugby team from the UFS will compete in the USSA Tournament in George on 30 November and 1 December 2015.

For the past two years, the team has won bronze, and will be playing three league matches on 30 November 2015 against the North-West University's Vaal Campus, Nelson Mandela Metropolitan University's Port Elizabeth Campus, and the Vaal University of Technology.

Kovsies are the current Varsity Sevens Champions after winning the title in Cape Town in April 2015.

Ten Kovsie swimmers took part in the USSA Tournament in Johannesburg from 28 November to 30 November 2015. Last year, Kovsies came third, but unfortunately some of their leading swimmers were unable to take part this year.

The Kovsie Table tennis team will participate in the USSA Tournament in Kimberley from 30 November to 4 December 2015.

Most of the USSA Tournaments in the other sporting codes were either postponed or cancelled because of the recent nationwide student protests. As a result of the protests, exams were written later, and tournaments would have taken place during the holidays.

Only the tennis, table tennis, Sevens rugby, swimming, and cricket B Division in East London will continue.

The USSA Soccer Tournament, to take place at the UFS and the Central University of Technology in Bloemfontein, was postponed until March 2016.
