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.”

Renewal process in JBM Hertzog Residence

2014-03-19

In February 2014, the JBM Hertzog residence community initiated a process of renewal. The review and reassessment of university symbols and traditions is nothing new; it takes place on a regular basis through the institution.

This means that various conversations take place to consult students on the evaluation of their residence’s values, symbols, systems and traditions in a changing South Africa. The university is deeply committed to continuously renewing its residence cultures through focused conversations in order to be more inspiring and welcoming to all students. The involvement of students in co-creating such spaces remains paramount.

The university regrets the deliberate and misleading information in the media on the process underway in JBM. The importance of student involvement consequently calls for the distribution of accurate information in order to avoid uncertainties, misunderstandings and incorrect perceptions.

It is therefore important to state the following regarding the current renewal process in JBM Hertzog:

1. No memorabilia or photos have been removed, and no final decisions have been taken in this regard. These decisions form an integral part of the consultation process described above.

2. The name of the residence (among other symbols) is part of the consultation process. It is also important to note that all suggested name changes at the UFS are subject to the approval of the institutional Naming Committee and the University Council.

3. The perception that this process is being used to eliminate certain unique cultural identities is incorrect. However, what this process aims to achieve is a more inclusive and welcoming residence culture, and throughout this will be done in consultation with all students.

All current residents of JBM Hertzog are invited to form part of this renewal process. In conclusion, the UFS wishes to convey its appreciation to the Residence Committee members and the residents for their positive attitude and continuous support during this very important process.
