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.”

Pres Steyn turns pink in anticipation of Vryfees

Australian artist Cigdem Aydemir vacuum packed the Pres Steyn monument on the Bloemfontein Campus’s Red Plain – in pink. Aydemir’s project, ‘Plastic Histories’, forms part of a public art project that encourages us to evaluate public monuments in their historical context.

By vacuum packing monuments, Aydemir alludes to their significance and preservation. At the same time, though, it reveals the nature of their contentious and gendered historical function. This is because most monuments in post-colonial countries typically celebrate men’s achievements in serving their nations.

In response, this project acknowledges the contribution of women from all races, communities and sexual orientations to the grand narrative of a post-apartheid South Africa.

Aydemir is also developing an app in collaboration with Australian artist Warren Armstrong. This will be used for augmented reality viewing of three city monuments – those of President Brand, General De Wet and General Hertzog. This means that visitors will be able to hold a smart phone or iPad in front of the monuments and view the monuments as if vacuum packed in pink plastic.

In conjunction with the public art project there will be an exhibition of digitally manipulated photographs of nineteen-century and contemporary male monuments in Bloemfontein. These photos will be exhibited at the Johannes Stegmann Gallery at the UFS Sasol Library from 15 July – 1 August 2014.

Public tours on the Bloemfontein Campus and into the city will take place on:

• Tuesday 15 July at 11:00,
• Wednesday 16 July at 14:00, and
• Saturday 19 July at 11:00.

Aydemir’s ‘Plastic Histories’ public art project is part of the UFS Programme for Innovation in Artform Development (PIAD) and the Vryfees arts festival’s partnership with the Australian-based SituateArt in Festivals initiative. This partnership is managed by the Salamanca Arts Centre in Tasmania.
