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.”

Shortage of quantity surveyors discussed at UFS

Shortage of quantity surveyors discussed at UFS

“The South African building industry is experiencing an unprecedented high level of economic growth and prosperity. This is causing a definite shortage of registered quantity surveyors,” said Mr Egon Wortmann, Director of the Association of South African Quantity Surveyors(ASAQS) during the association’s recent visit to the Department of Quantity Surveying and Construction Management at the University of the Free State (UFS).

“This shortage is especially noticeable in local and national governments where unqualified and inexperienced staff, consultants and/or facilitators are now appointed,” said Mr Wortmann.

In doing so, the authorities that have adopted this approach are according to Mr Wortmann actually acting illegally and are not in compliance with the legal and statutory requirements of South Africa. “These unprofessional practices are unproductive, it leads to frustration and is strongly condemned by the ASAQS,” he said.

“The service delivery of these unqualified and unregistered service providers is often sub standard and does not comply to the legal requirements of the profession. It may also result in the tarnishing of the image and high professional standards set by the quantity surveying profession,” said Mr Wortmann.

“Universities offering programmes in quantity-surveying and construction management are also negatively affected by the high levels of activity in the building environment. Suitable lecturing staff are leaving the academic institutions as they are attracted to better opportunities being offered in the building industry. The ability of the tertiary institutions to attract young academics, to train them and to keep them in the longer term, is therefore almost impossible”, said Prof Basie Verster, head of the Department of Quantity Surveying and Construction Management at the UFS and representative of the Free State on the ASAQS.

According to Prof Verster the UFS supplies more than its quota of qualified quantity surveyors to the South African building industry. “Although more than 460 students are registered in construction related programmes at the UFS, we are as the ASAQS’s concerned about the shortage of students that can enter the construction industry. In our case, we are experiencing a shortage in black female students,” he said.

“Of the 460 postgraduate students, 38% are black of which 20% are female students. Graduates do also not necessarily stay in the country. As the UFS’s programmes are accredited overseas, a lot of our students leave the country for working opportunities elsewhere,” said Prof Verster.

Mr Patrick Waterson, President of the ASAQS, appealed to quantity surveyors to, when they are approached, consider academic careers or to make themselves available to lecture on a part time basis. “I also appeal to quantity-surveying practices, construction companies and developers to consider taking part in training activities,” he said.

The ASAQS has over the years developed a proud tradition within the quantity-surveying profession. Consequently membership of this organisation is a sought after goal for many members within the building environment. International agreements with various countries are also in place whereby it is mutually agreed that local as well as overseas qualifications are mutually acceptable on a reciprocal basis.

A more recent addition to the list of agreements is the reciprocity agreement entered into with the Royal Institution of Chartered Surveyors which makes it possible for South African based quantity surveyors to practice in over 120 countries worldwide.
