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.”

“Make the choice to make a difference as the leaders of the future.” These words of Dr Susan Vosloo, Cardiothoracic Surgeon and member of the University of the Free State (UFS) Council, echoed the call to graduates on the first three days of the UFS mid-year graduation ceremonies. The ceremonies are taking place in the Callie Human Centre on the Bloemfontein Campus from 19 to 26 June 2017.

Dr Vosloo, also an alumna of the UFS, was one of six guest speakers at the biggest set of graduation ceremonies in the university’s history. A spirit of excitement is part of the festivities, as a total of 5 258 degrees will be conferred over six days in eleven ceremonies. The graduation week will conclude on 26 June 2017, when 460 master’s and doctoral degrees will be conferred – 72 of these are doctoral degrees.

Stand up and be counted
Dr Vosloo urged the graduands at the afternoon session on 19 June 2017 to stand up and be counted. “What we need are leaders who treasure integrity, dignity, accountability, transparency, and who will focus on the common challenges which we all face today.”

Dr Khotso Mokhele, UFS Chancellor, also encouraged the graduates to be agents of change who shouldn’t conform to the current system. “Decide that it is your country and that you will decide what it should be. Then it will not be the corrupt experiment which the current government turned it into. We wish you well. Go and be the agents of transformation.”

Ambassadors of the UFS
Prof Francis Petersen, UFS Rector and Vice-Chancellor, asked the graduates to make a contribution: “Be excellent ambassadors of the UFS, and make the UFS, your families, and our country proud by your strong, innovative, ethical, and excellent contributions.” He was the guest speaker during the morning and afternoon sessions on 20 June 2017.

He also said that they should never forget the supporting role others played in their success, whatever form it took.

Do it for those who fought for SA
Justice Connie Mocumie, Judge of Appeal at the Supreme Court of Appeal, encouraged the graduates to go out and contribute to the development of the country. She was the guest speaker at the morning and afternoon ceremonies on 21 June 2017.

“It is important for you to continue being experts in your area of expertise,” she said.

“Today is the beginning of better days to come. Do it for the legacy of those who fought for our country in pursuit of a better South Africa.”

Dipiloane Phutsisi, Principal and Chief Executive Officer of the Motheo TVET College in the Free State, said everyone is destined for greatness. “In the words of Dr Martin Luther King: Everyone has the power for greatness, not for fame but greatness, because greatness is determined by service.” She was the guest speaker at the morning session on 19 June 2017.
