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.”

The university has created another beacon for social justice and reconciliation with the launch of its first Human Rights Desk (HRD) on the Bloemfontein Campus. The HRD, which falls under the Institute for Reconciliation and Social Justice, will promote, protect and monitor human rights at the university.

Speaking at the launch of the HRD, Prof Andre Keet, Director of the Institute for Reconciliation and Social Justice, said the desk will investigate reported violations of human rights on campus. "It will investigate any cases that require investigation, as well as various other projects that serves the university and national and international imperatives as far as human rights is concerned.”

Prof Keet told students and staff in attendance that the desk is an expression of the university's commitment. "As a university, we have to own this particular desk, as a collective entity we should make it work and be proud of it. Our task is to build a new form of productivity into the language of rights, and build a culture of human rights among our students, which we can already see emerging."

Also speaking at the event, Prof Jonathan Jansen, Vice-Chancellor and Rector, said the HRD will be a place where people can come who are hurt. He encouraged students to speak on human rights anywhere in the world. "I want you to think of yourself as a borderless human being, for human rights are not geographically confined. I want you to also hurt when somebody in a mall in Kenya gets hurt."
