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.”

Former architecture student takes part in Archiprix in Moscow

2013-06-24

Jurie Swart in Moscow.
24 June 2013

“I am proud that I could honour the UFS’ name,” says Jurie Swart. He participated in the prestigious Archiprix in Moscow in May 2013.

Archiprix is an international competition where the world’s top architecture students are selected. Architecture departments, schools and faculties of 1 500 universities from 78 countries worldwide are invited to enter their top master’s students over two study years.

In 2012, Jurie Swart was honoured as regional winner of the Corobrik Architectural Student of the Year Award and also received an honourable mention in the 2012 International Graduate Architecture Projects.

After several months of careful evaluation by a panel of five experts, his thesis, Borderline – mediated landscape, A water research centre for the University of the Free State, Qwaqwa Campus, was nominated as one of the world’s 25 master’s projects to take part in the Archiprix in Moscow. His thesis was also on display at the Central House of Artists in Moscow for a couple of months.

The judges were Yuri Grigoryan (architect and director of the Moscow-based Project Meganom, as well as director of educational programmes at the Strelka Institute in Moscow); Susan Herrington (professor of architecture and landscape architecture at the University of British Columbia in Vancouver, Canada); Kristin Jarmund (architect and director of the Norwegian-based Kjark, an architectural house); Hubert Klumpner (architect, director of the Venezuela-based Urban-Think Tank, and professor of architecture and urban design at the ETH, Zürich ); and Lesley Lokko (architect, academic and author from the UK).

Jurie Swart was selected as the participants’ favourite. “From the top 25, seven winners were announced, and although I didn’t win, it is still an amazing achievement and I am proud to have honoured the university’s name,” he said.

During his visit to Moscow, he also attended a workshop with the rest of the nominated students. This project, with the theme Railroads, was an exercise to help solve Russia’s transport problems.
