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.”

The Council of the University of the Free State (UFS) unanimously re-elected Judge Ian van der Merwe as its Chairperson for the next three years at its last meeting for this year on Friday, 16 November 2012.

Judge Van der Merwe is a Judge of the Free State High Court. He is an alumnus of the UFS and has been a member of the Council since 9 March 2007.

In accepting his appointment, Judge Van der Merwe said that he was honoured and humbled to lead a Council of this calibre for a second term. “The Council is setting a good example of what good governance at a higher education institution should look like. Meetings are conducted in good spirit and decisions made in the best interest of the university,” he said.

“Having sat on councils of many universities before, I can say with great surety that, on balance of expertise and backgrounds, the UFS has one of the most effective councils in the country and, to have a Chairperson of Judge Van der Merwe’s stature, is a privilege. His leadership and guidance is greatly appreciated,” said Prof. Jonathan Jansen, Vice-Chancellor and Rector.

Mr Edward Kieswetter, Group CEO and Executive Director of Alexander Forbes and Deputy Chairperson of the UFS Council, and Mr Jonathan Crowther (former editor of Volksblad) have been re-elected for a further term of four years in the category: "Appointed by the Council".

External Council members were given a tour of the Bloemfontein Campus after the meeting, followed by an induction session for new council members.

New Council members who joined this year are:

Derek Foster, in the category appointed by the Council
Ruben Gouws, elected by the non-academic staff
Lorraine Kriek, elected by the Alumni
Themba Mmabi, representative of the Minister of Higher
Education and Training
Sabelo Khumalo, SRC President, Qwaqwa Campus
William Clayton, SRC President, Bloemfontein Campus
Suraya Jawodeen, representative of the Minister of Higher
Education and Training
Mr Dan Mosia, representative of the Minister of Higher Education and Training
