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 committed to a two-language model
2010-08-13

  Prof. Jonathan Jansen

The University of the Free State (UFS) will continue to use a two-language model while it builds capacity for research and teaching in Sotho languages.

This was announced by the Rector and Vice-Chancellor of the UFS, Prof. Jonathan Jansen, when he delivered the 29th DF Malherbe Memorial Lecture on the Main Campus in Bloemfontein yesterday, on the topic: The politics and prospects of Afrikaans, and Afrikaans schools and universities.

“In the course of time black students will learn Afrikaans, white students will learn Sesotho, and all students will learn decent English,” he said.

“Classes will remain in English and Afrikaans, especially in the first years of study. Dual-medium classrooms will break down the racial isolation where outstanding university teachers are comfortable in both languages. Parallel-medium classes will exist where large numbers enable such a facility.”

He said schools and higher education institutions that continue to use language as an instrument of exclusion, rather than inclusion, would remain “culturally and linguistically impoverished”. He said the future of Afrikaans in these institutions lay in its inter-dependence and co-existence with other languages.

“A strong two-language model of education, whether in the form of double- or parallel-medium instruction within a racially integrated campus environment is the only way in which Afrikaans can and should flourish in a democratic South Africa,” he said.

“It is the only model that resolves two problems at the same time: the demand for racial equity, on the one hand, and the demand for language recognition, on the other hand.”

He said the idea of an exclusively Afrikaans university was a “dangerous” one.

“It will lock up white students in a largely uni-racial and uni-lingual environment, given that the participation rates in higher education for Afrikaans-speaking black students are and for a long time will remain very low,” he said.

“This will be a disaster for many Afrikaans-speaking students for it will mean that the closed circles of social, cultural and linguistic socialization will remain uninterrupted from family to school to university.

“Rather than prepare students for a global world marked by language flexibility and cultural diversity, students will remain locked into a sheltered racial environment at the very stage where most South African students first experience the liberation of the intellect and the broadening of opportunities for engaging with the world around them.

“The choice at the Afrikaans universities, therefore, must never be a choice between Afrikaans and English; it must be both.”
