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.”

Breyten Breytenbach shares his words and philosophies

The Department of Philosophy at the University of the Free State (UFS) recently hosted Breyten Breytenbach as part of its Colloquium series.

In a packed Odeion theatre, Breytenbach shared his words and views relating to poetry and philosophy. The session was chaired by Prof Pieter Duvenhage from the Department of Philosophy, who noted the symbiotic relationship which exists between the two seemingly distinct disciplines.

Breytenbach is one of South Africa’s best-known literary sons, gaining worldwide recognition for his writings and poetry, as well as his political activism against the erstwhile Apartheid regime. He left the country in 1960 due to Apartheid and settled in Paris where his first collection of poetry was published in 1964. It was the beginning of a prizewinning literary career spanning multiple languages and decades.

He returned illegally in 1975 in order to agitate against the repressive National Party government, but was arrested, spending seven years in prison after being charged with terrorism.

The audience was treated to a reading from an unpublished work from Breytenbach, A letter to my daughter. The lengthy letter outlined Breytenbach's world views, his sense of the creative process, his philosophies and his takes on current and historical events.

A large part of the letter focused on the philosophical and emotional processes involved in writing.“Writing is the travelling of its own landscape; landscapes and rooms that may always have been there,” he said.

He noted that it’s not always an easy process, and that sometimes writers need to explore the abysses, which can be unnerving.

“In this regard it is important to know that emptiness exists,” he said.

He stressed his concern over some of the problems the country currently faces, especially the abuse of state institutions. He was especially worried about the abuse of power. He warned that “power has its own predatory identity,” often abused and misused by those who wield it.

Despite his misgivings, Breytenbach still retains his optimism for the country and its people. He remarked that the country and its many diverse cultures resembles a “fantastic patchwork blanket,” one that should be cherished and protected.
