Dr Falko Buschke says the iconic sandstone cliffs of the eastern Free State are key to protecting wild plants and animals from climate change.

The iconic sandstone cliffs of the eastern Free State are often the focus of paintings and postcards. Now, new research shows they also protect wild plants and animals from climate change. This finding is the outcome of a collaborative research effort by the University of the Free State (UFS); BirdLife South Africa; the Vrije Universiteit Brussel and KU Leuven, Belgium, which has recently been published in the journal Biological Conservation.

Mountains key for climate change mitigation

The study, led by Dr Falko Buschke from the Centre for Environmental Management UFS, used satellite data from NASA to track the ecological effects of wet and dry seasons, including the record drought of 2015/16. This showed how vegetation on the cool and moist mountain slopes was less affected by dry spells.

The complex physical terrain allows moisture to accumulate in the shaded parts of the south-facing slopes and ravines. This creates cool and moist habitats for plants and animals that wouldn’t survive in the rest of the hotter and drier landscape.

The team also discovered that these positive effects of mountains do not end at the foot of the mountain, but extend at least 500m into the flatter lowlands. “Presumably because water and nutrients accumulate in these surrounding buffers due to run-off,” says Dr Buschke.

Butterflies find safety on mountains

In addition to their high-tech analysis of the area, the team also relied on old-fashioned fieldwork to monitor butterflies over two years. “The data showed us how these insects find safety on mountains during harsh climate conditions and can then recolonise the rest of the landscape after conditions improve,” explains Dr Buschke. “This gives us clues on the best way to protect nature,” he adds. 

This study took place in the Rooiberge-Riemland Key Biodiversity Area (KBA), an area significant for maintaining global biodiversity. Several species of insects, reptiles, birds and mammals here occur nowhere else on earth. “If they disappear here, they will go extinct from the whole planet forever,” says Dr Falko Buschke. 

Despite its ecological significance, most of the area is covered by commercial farmland. So, the next stage of the project is exploring ways of protecting these important habitats while ensuring that farmers can continue producing food and supporting rural livelihoods. 

Farmers hold the key to preserving biodiversity,” says Dr Buschke, “so conservation scientists need to work closely with them to ensure that we protect species for future generations.”

UFS awards honorary doctorates during spring graduation ceremony
2004-09-20

The University of the Free State (UFS) will award three honorary doctorates this week during its spring graduation ceremony.

The graduation ceremony will take place on Wednesday 22 September 2004 and the honorary doctorates are Dr Calvin Seerveld (D Phil (hc), Prof YK Seedat (MD (hc) and Dr Mary Seely (D Sc (hc).

“The doctorates come from a wide spectrum of specialty fields and serve as proof of the UFS’s policy to give recognition to people who stand out and make a difference,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

Dr Calvin Seerveld (D Phil (hc) will receive an honorary doctorate for his academic leadership at the Institute for Christian Studies in Toronto and the wide international recognition he has received throughout his career in various subject areas, eg philosophical aesthesia, the theory of art, the methodology of the description of the history of art and continental philosophy.

Prof YK Seedat (MD (hc) will receive an honorary doctorate for his extraordinary contribution to medicine in South Africa. His research in the field of hypertension in blacks received international recognition and significantly contributed to the understanding of the pathophysiology of this condition.

In the mid-eighties Prof Seedat was instrumental in supporting the bid from the Faculty of Medicine at the University of the Orange Free State (UOFS) to host the first Colleges of Medicine of South Africa examination in Bloemfontein. This started a tradition that is still being maintained. Prof Seedat is a researcher at the Faculty of Health Sciences at the University of Kwa-Zulu Natal.

The Executive Director of the Desert Research Foundation of Namibia, Dr Mary Seely (D Sc (hc)), will be honored for the impact she has made on the development of environmental management in the drier parts of the southern African subcontinent. Though her research has been concentrated in Namibia, she has affected the professional lives of large numbers of ecologists, environmental scientists and environmental managers.

According to Prof Fourie the three doctorates form part of the greater group of 18 who will be honored by the UFS during its centenary year. The last group will be receiving their honorary doctorates in October 2004.
