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 Department of Architecture Building receives SAIA Award

2014-08-21

The South African Institute of Architects (SAIA) conferred a national merit award on renovations and additions to the DHET UFS Department of Architecture Building. The UFS is very proud of this award.

The building, which was completed in 2012, was designed by Typology Architects' director, Henry Pretorius. Pretorius is also the Head of the Department of Architecture at the UFS.

“The merit award by the South African Institute of Architects, which was presented on 1 August 2014 at the International 2014 UIA congress (held for the first time in South Africa), is a great honour. Not only does the award recognise my work as an architect, it also brings back a certain degree of pride to the Free State and especially the UFS’s Department of Architecture,” says Pretorius.

The SAIA Awards Programme runs over two years to coincide with the presidential term of office, starting with the Regional Awards for Architecture during the preceding year.

A total of forty-nine (49) entries for varying buildings were received from the regions. The project range included residential projects, new public buildings, restoration of heritage projects and an academic research project.

From these submissions, fourteen (14) projects received merit awards, of which eight (8) projects received excellence awards.

The adjudication panel comprised:
• Sandile Ngonyama: SAIA President
• Paul Kotze: Architect, planner and academic from WITS
• Malcolm Campbell: Architect from ACG Architects in Cape Town
• Annemarie Meintjies: Deputy editor of VISI magazine, representing a prominent member of the public
• Peter Kidger: representative of Corobrik, sponsor of the awards.
