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.”

UFS Safety Awareness March set to create a safe space for students

2017-07-27

The University of the Free State (UFS), in collaboration with various stakeholders, has dedicated the week of 24 to 28 July 2017 to creating awareness for the safety of students on and around its campuses.

UFS and CUT unite for safety
The highlight of the week will be on Thursday 27 July 2017 when a safety awareness march will take place from the Main Building on the Bloemfontein Campus to the Bram Fischer Building, where a memorandum will be handed over to Mr Sam Mashinini, MEC for Police, Roads, and Transport in the Free State. The march is a partnership between the UFS Student Representative Council (SRC) and the Central University of Technology (CUT).

During a meeting on 24 July 2017, the Executive Committee of Senate granted formal approval for students and staff of the Bloemfontein Campus to take part in the safety march on 27 July 2017. For this reason, all lectures will be suspended from 11:00 to 13:00 on 27 July 2017 in order to give the campus community the opportunity to participate in the march. Academic staff, as well as staff in the administrative support services, are encouraged to join the march.

Programme for the safety march:

11:00: Marchers gather in front of the Main Building

11:15: Marchers depart from the Main Building to the Main Gate

11:30: Marchers exit the Main Gate and move towards the Central University of Technology (CUT). Students and staff who are unable to participate in the rest of the march, return to their work places or classes.

12:20: UFS and CUT marchers will gather at the Bram Fischer Building, situated on the corner of Nelson Mandela Avenue and Markgraaff Street. Here, the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, and the Vice-Chancellor and Principal of CUT, Prof Henk de Jager, will address the marchers, after which the memorandum will be read by the respective SRC Presidents and handed to Mr Mashinini.

Activities underway to raise safety awareness
During the week, the Student Representative Council (SRC), together with other stakeholders, have been involved in several activities on and off the Bloemfontein Campus, including door-to-door visits to student homes and residences on and around campus, awareness campaigns at all the gates of the campus, and a Safety Dialogue that will be held on Wednesday 26 July 2017 at the Equitas Auditorium. The aim of the Safety Week is to focus on informing, educating, and encouraging students as well as the Mangaung community at large, in order to work together in creating a safe environment for students.

The week started with the roll-out of an awareness campaign titled Reach Out, which is set to bring students and the community of Mangaung together to help decrease the number of violent crimes faced by students off campus. The communication plan includes safety messages, using outdoor billboards, posters on lampposts around the residential student areas, local community radio stations, campus media, and the university’s social media platforms.

A similar student safety awareness campaign will take place on the university’s Qwaqwa Campus during the week of 31 July 2017.
