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.”

Zubeida Jaffer short film to feature on SABC3

The nation-building initiative known as 21 ICONS South Africa, was recently thrilled to announce that Zubeida Jaffer will feature in their second season due to her professional excellence as a journalist and author.

Jaffer is a well-known South African reporter and author and has been a writer-in-residence at the UFS for three years now. The 21 ICONS project was inspired by Nelson Mandela and has created a movement for positive change. By sharing the stories of iconic South African men and women, the intention is to inspire new generations to follow in their footsteps.

One icon is featured per week in a visual celebration of engaging and entertaining portraits and short films, along with an essay biography across multiple media platforms such as print, broadcast, outdoor and social media. Jaffer’s short film will be broadcasted on 2 November 2014 at 20:27 on SABC3 and her collectable portrait will be published in City Press on the same day.

Jaffer’s short film discusses her truth as a journalist and activist who was a key figure in the struggle movement in the Western Cape during apartheid. In an intimate conversation with Adrian Steirn (creator, photographer and director of 21 ICONS, Jaffer talks about her journey as a journalist who always seeks to uncover the truth and give people who don’t have a voice an outlet to express their views, opinions and thoughts.

Other iconic South Africans that have featured on 21 ICONS, were among others, Francois Pienaar (former Springbok rugby captain who won the 1995 Rugby World Cup), Pieter-Dirk Uys (satirist who used comedy and caricature to oppose the apartheid government) and Frene Ginwala (the first female speaker in the National Assembly of South Africa).

With the country celebrating 20 years of democracy, the message that everyone can do something to make a difference – which is portrayed in these powerful and inspiring stories that make up the second season of 21 ICONS – has been well-received by South Africans.

Be sure to get your City Press early and tune in on the evening of 2 November 2014 to see Jaffer’s feature on 21 ICONS.

Jaffer is also the publisher of the Journalist website (http://www.thejournalist.org.za/) launched earlier in 2014, of which the UFS is the founding member. The Journalist is “an independent, non-profit organisation working with the academic community and a range of credible online entities to make their knowledge more accessible to the wider public.”
