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 appoints new council members
2004-06-07

 

The council of the University of the Free State (UFS) last week appointed two new council members. One of the members, Mrs Busiswa Tshabalala, will represent the Qwaqwa community. It is the first time since the incorporation of the Qwaqwa into the UFS campus last year that a council member was elected to represent the Qwaqwa community.

Mrs Tshabalala obtained her BA Hons in History from the University of the North’s Qwaqwa campus in 1992 and a B Ed degree in leadership management from the UFS in 1998. She was the first female deputy principal at the Harrismith Secondary School (1989-1992) and principal of the Forty Second Hill Teachers’ Centre in the Vrede area office of the Free State Department of Education. In 2001 she was seconded by the Free State Department of Education to coordinate programme 1 and 2 for Link Community Development. She is currently the director of the Thabo Mofutsanyana education district of the Free State Department of Education.

Dr Susan Vosloo, international acclaimed cardiologist, is the other new member of the council. Dr Vosloo, old Kovsie of the year 1989, obtained the MB Chb degree in 1980 at the UFS, an M Med cardiothoracic surgery and in 1998 the FCS (SA) qualification in cardiothoracic surgery at the College of Medicine of South Africa (CMSA). Dr Vosloo’s career extends over a wide spectrum and she specialises in pediatric and adult cardiothoracic surgery. In 1993 she took part in the first heart transplant in Johannesburg at Milpark Hospital, in 1997 she did the first hear-lung transplant at City Park Hospital in Cape Town and in 1997 a heart transplant on a 3-year old child.

She has a cardiothoracic surgery at the Christiaan Barnard Memorial Hospital in Cape Town since 1991 and in also part-time involved with the Red Cross Memorial Hospital in Cape Town.

“It is a great honour for the UFS to welcome two women with so much expertise and experience on the council. Their presence strengthens the UFS’s continued effort to transform the council,” said judge Faan Hancke, chairperson of the UFS council..

Both Mrs Tshabalala and Dr Vosloo’s appointments are until June 2008.

The following council members have been re-elected until June 2008:

Prof Dines Gihwala - vice-chairperson of the council
Dr Nathan Bagarette
Dr Frans Kotzé

Dr Kobus Laubscher was elected by the donors as representative for a further term until June 2008. Me Winifred Hoexter was elected by the Alumni as the third representative. She has been a foundation donor of the UFS since 1997 and committee member of the Kovsie Alumni Trust since 2000. Me Hoexter’s term is until June 2008. The other Alumni representatives are judge Faan Hancke and Mr Jan Grobler, whose term is until June 2006.
