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 council appoints new representatives   

Three new representatives were elected on the University of the Free State’s (UFS) Council during its second seating for 2006.  This includes representatives from the religious community, alumni, donors and the Minister of Education.

Ms Cheryl Gillwald, former Deputy Minister of Correctional Services, has been appointed by the Minister of Education as ministerial representative in the place of Prof Shirley Walters and will serve for the rest of Prof Walters’ term.

Father Patrick Towe, Roman Catholic priest from Bloemfontein, was appointed as representative of the religious community.  Father Towe is member of the Missionary Oblates of Mary Immaculate and chairperson of the UFS Campus Ministries. 

Adv Mauritz Randlehoff, joint deputy chairperson of the national Kovsie-Alumni Association and deputy chairperson of the Kovsie-Alumni Trust, was elected as one of the three representatives out of UFS alumni on the Council.  Judge Faan Hancke was re-elected as representative of the alumni for a second term.

Mr Klippies Steenkamp as representative of the UFS donors has also been re-elected.  He was, among others, chairperson of the Kovsie-Alumni Association and founding member of the Kovsie-Alumni Trust’s council of trustees.

The university also bid farewell to two members of Council, Dr Vicky le Roux and Mr Jan Grobler.  Both were members of the Executive Committee of the Council.  Mr Grobler represented the UFS Council in the Institutional Forum and Dr le Roux was a representative of the Council in the Institutional Forum and the Senate. Together they have serve thirty nine years on the Council.
