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.”

Kovsies well represented in Cheetah rugby team
2006-10-10

Champions support champions.  Sport stars from the University of the Free State (UFS) today pledged their support to the Cheetah team with their participation this weekend in the Currie Cup final.  From the left are:  Boy Soke (SA Cross Country Champion), Nicolaas le Roux (captain of the Shimla rugby team), prof Frederick Fourie (Rector and  Vice-Chancellor), Ben Rheeder (Shimla hooker) and Charlene Hertzog (Captain of the Protea team and the UFS first netball team).

Kovsies well represented in Cheetah rugby team

Altogether 10 current and former Kovsies will most likely be included in the Cheetah team of 22 players that will compete for a place in the team that will play against the Blue Bulls on Vodacom Park in Bloemfontein in the final game of the Currie Cup.

“The University of the Free State (UFS) is proud of its rugby players and sees this milestone as another example of our commitment to maintaining quality sports performances,” said Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

Prof Fourie said the UFS will stand solidly behind the Cheetahs this weekend so that the Currie Cup can stay in the Free State.

“It is not every day that we can boast with such a high representation in a provincial team.  Each of these players has proven himself to be a true sportsman and some of them are also Springbok rugby players.  This makes the honour even greater for the UFS,” said Prof Fourie.

The current and former Kovsies are Ollie le Roux (captain and loose head prop), Wian du Preez (loose head prop), Richardt Strauss (hooker), Jannie du Plessis (tight  head prop), Noël Oelschig (scrumhalf), Michael Claassens (scrumhalf), Meyer Bosman (flyhalf), JW Jonker (center, back line), Philip Burger (flyhalf/back) and Jaco du Toit (hooker). 
“Last year we honored two former Kovsies for their contribution to the success of the Cheetah team.  Mr Naka Drotské, team manager of the Cheetahs, was appointed as  Kovsie of the Year and Mr Harold Verster, President of the Free State Rugby Union, received the Cum Laude Award,” said Prof Fourie.
