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 Department of Quantity Surveying and Construction Management at the University of the Free State (UFS) made good on its promise to develop independent and critical-thinking graduates who will become leaders in their field. At the recent Association of South African Quantity Surveyors (ASAQS) conference and gala dinner, two students from the department, Gerné Botma and Jhon Thatcher, received awards for their outstanding performance.

Best of the best
Botma received the ASAQS Future Leaders’ Award (2017), an award based on academic achievement in the first three years of study. He competed with nominees from universities across South Africa offering Quantity Surveying programmes, and was the winner in this category.

Thatcher was a second runner-up for the ASAQS Gold Medal Award (being in the top three Quantity Surveying students in South Africa). This is awarded on a number of criteria, including academic achievement. Fourth-year students from all the universities in South Africa offering Quantity Surveying programmes compete for this award, and must display achievement in categories such as academia, leadership, community engagement, and general interests. In 2016, the Gold Medal Award was won by the UFS student, Kamogelo Leeuw.

Keeping abreast of developments
Today, organisations are relying on its members to stay ahead of issues, technologies, innovations and trends. In Quantity Surveying, to keep abreast of developments in the built environment, ASAQS was established as a voluntary association, with one of its goals being advancing and promoting the science and practice of Quantity Surveying. ASAQS works in close collaboration with its member firms, tertiary institutions, and the South African Council for Quantity Surveying Professions (SACQSP), a statutory body that oversees and regulates the profession, and accredit Quantity Surveying programmes in South Africa.

Two staff members from the UFS Department of Quantity Surveying and Construction Management, Cameron Ferreira and Pierre Oosthuizen, attended the recent ASAQS annual conference. Ferreira, a junior lecturer in the department, is the current Chapter Chairperson of the Free State for ASAQS and Oosthuizen, a lecturer in the department, is the former Chapter Chairperson.

According to Ferreira, they attended the conference to keep abreast of the latest development within the industry. “The event also served as a great networking opportunity for the UFS to build partnerships with other industry pioneers,” she said. Making use of opportunities such as these is in line with the UFS’s pursuit of lifelong learning.
