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.”

Kovsie hockey achieves
2010-07-22

Gregg Clark

Three players from the University of the Free State (UFS) Womens Second Hockey Team, Theane Guthrie, Ayesha Samuels and Chantelle Deere, were selected for the South African Country Districts A Team. Theane, Ayesha and Chantelle played for Free State B Team when they participated in the recent SA Country Districts Hockey tournament. The Free State B Team also won the Tournament. 

Jason Klinkradt, coach of the UFS Womens Second Team, was also the coach for the Free State B Team.

Eight Kovsies were also included in the Free State Hockey Team that will participate in the National Interprovincial Hockey Tournament in East-London from 19-24 July 2010. The players are Lesley Ann George (captain), Berne van Wyk, Jo-Nelka Swanepoel, Felicia Shongwe, Orpah Pretorius, Cardeux Nel, Nicole Kemp and Hettie Oosthuizen. The Protea under-captain, Lesley Ann is the captain of the Free State Team. Elsie Coetzer, the Kovsie womens hockey coach, is also the coach of this team.

More news from Kovsie hockey is that the national mens coach, Mr Gregg Clark, presented a very successful training camp for the Free State womens and mens teams on the Kovsie Astros. The training camp was open to all Free State coaches and was amongst others attended by Elsie Coetzer and Des Donald, Kovsies mens hockey coach.

Mr Clark was also course leader at the hockey course for schools, attended by 900 learners, presented by the Kovsie Hockey club earlier this year, said Mr Frans van der Watt from KovsieSport.
