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.”

Renewable energy systems an economical investment for the UFS

Renewable energy systems are said to be very expensive to implement initially, but in the long run they provide high economic returns.

With their decision to install renewable energy, the University of the Free State Department of Facilities Planning has now also adopted this innovative technology. They have chosen less capital-intensive solar power-generating options to generate electricity in various buildings and parking areas on all three UFS campuses.

“As per the UFS Energy Management Policy, all designs incorporate efficient, renewable energy sources varying from LED lights to solar power,” says Anton Calitz, Electrical Engineer in University Estates’ Department of Facilities Management.

South Campus taking the lead in renewable energy usage
In December 2016, a total of 26 solar-driven LED street-light poles were installed at the recently built Legae Residence’s parking area and the perimeter security area on the South Campus. This low-maintenance system improves security after dark and is independent of the national power supply, which is an important advantage during power outages. With no requirements for major earthworks and cable setting, operational costs are reduced.

The recently built infrastructure also takes pride in being the first to have a greywater system installed.  This system will also be installed at three other residences on the Bloemfontein Campus in 2017. Greywater is made up of bath, shower, and bathroom sink water. The water is reused for toilet flushing, as well as for irrigation purposes.

Various UFS electrical operations to depend on solar power
On the Bloemfontein and Qwaqwa Campuses, the computer laboratories as well as the Thakaneng Bridge Student Centre and the projected Afromontane Research Centre will be equipped with freestanding roof solar solutions during 2017. These systems are designed to operate independently of the power grid (Eskom).

The systems only operate during sunlight hours when the PV solar panels are heated by the sun, making them suitable for operations such as ventilation fans, water pumps, and small circulation pumps for solar thermal water-heating systems.
