ARU pioneering mountain range-expanding project

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.”

UFS council appoints new representatives

Three new representatives were elected on the University of the Free State’s (UFS) Council during its second seating for 2006. This includes representatives from the religious community, alumni, donors and the Minister of Education.

Ms Cheryl Gillwald, former Deputy Minister of Correctional Services, has been appointed by the Minister of Education as ministerial representative in the place of Prof Shirley Walters and will serve for the rest of Prof Walters’ term.

Father Patrick Towe, Roman Catholic priest from Bloemfontein, was appointed as representative of the religious community. Father Towe is member of the Missionary Oblates of Mary Immaculate and chairperson of the UFS Campus Ministries.

Adv Mauritz Randlehoff, joint deputy chairperson of the national Kovsie-Alumni Association and deputy chairperson of the Kovsie-Alumni Trust, was elected as one of the three representatives out of UFS alumni on the Council. Judge Faan Hancke was re-elected as representative of the alumni for a second term.

Mr Klippies Steenkamp as representative of the UFS donors has also been re-elected. He was, among others, chairperson of the Kovsie-Alumni Association and founding member of the Kovsie-Alumni Trust’s council of trustees.

The university also bid farewell to two members of Council, Dr Vicky le Roux and Mr Jan Grobler. Both were members of the Executive Committee of the Council. Mr Grobler represented the UFS Council in the Institutional Forum and Dr le Roux was a representative of the Council in the Institutional Forum and the Senate. Together they have serve thirty nine years on the Council.
