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 Digital Doorway project will change lives in Heidedal

The combined effort of ICTISE (ICT Innovation in School Education), Reach and the Heidedal community saw a four-station Digital Doorway (computer system) being placed on the premises of Reach at the end of 2010. ICTISE is a programme of the University of the Free State (UFS) and operates from the university’s South Campus. This computer system will allow all Heidedal schools and community members to have free access to computers.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, opened the Digital Doorway by cutting a ceremonial ribbon with the assistance of one of the community’s learners.

The Digital Doorway concept originates from a joint initiative between the Department of Science and Technology and the Meraka Institute of the Council for Scientific and Industrial Research. The Digital Doorway consists of four screens and allows access to select content, including open-source application software. This includes audio books, subject textbooks, encyclopaedia, educational games such as “touch maths” and quizzes as well as useful information for school subjects and a newspaper especially for children.

The Heidedal Digital Doorway is the first of its kind in the Motheo District. Typically, one or two kids will be working on each of the computers, while up to five other learners will be giving instructions, allowing the whole group to learn. The Digital Doorway is a smart way of bridging the digital divide, bringing science and technology to our community and opening the doors of learning. ICTISE will support the Heidedal schools to make full use of this new facility by training teachers and community members.

“The UFS hopes that this project will change the lives of the Heidedal community by providing the youth with an opportunity to be in line with the changing world of technology,” said Ms Sarietjie Musgrave, Head: ICTISE.
