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.”

Well-known academic and human rights lawyer Prof Barney Pityana will deliver the inaugural Bram Fischer Memorial Lecture on Friday 26 April 2013,honouring the life and legacy of the anti-apartheid stalwart. Prof Pityana will be joined by Fischer’s daughters Ruth Rice and Ilse Wilson and his nephew Peter in the President CR Swart Auditorium on the Bloemfontein Campus.

Prof Pityana has an impressive track record of accomplishments:

He is the current Rector of the College of the Transfiguration in Grahamstown; one of the founding members of the South African Students' Organisation; an important figure in the Black Consciousness Movement with Steve Biko; and an exponent of Black theology.

Prof Pityana is the former Principal and Vice-Chancellor at the University of South Africa (UNISA) and also a former chairperson of the South African Human Rights Commission.He has served on the African Commission on Human and Peoples' Rights at the Organization of African Unity in 1997. Prof Pityana’s work in human rights has been widely recognised and in December 2002 he was awarded an Honourable Mention of the 2002 UNESCO Prize for Human Rights Education.

In April 2006, Prof Pityana received the Award of the Order of the Grand Counsellor of the Baobab: Silver from former President Thabo Mbeki.

Prof Pityana will meet with students from the Faculty of Law during the day of the lecture. At 12:00 the Institute for Reconciliation and Social Justice will host a critical conversation discussing Bram Fischer as a father and Afrikaner communist lawyer. The conversation will feature the perspective of his daughters. The Bram Fischer Memorial Lecture will commence at 18:30.
