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.”

Three Kovsies in Protea Women’s Hockey team

Three Kovsies were included in the Protea Women’s Hockey team to compete in a qualifying Africa tournament for the Olympic Games.

Tanya Britz, Nicole Walraven, and Cornelle Botha were chosen to represent their country in Randburg, Johannesburg, from 23 October to 1 November 2015.

All three have been playing for the Kovsie Women’s Hockey team in the Varsity series. The team lost in the finals against the University of Johannesburg in Bloemfontein.

The trio are the only Free State players in the South African group.

Five current Protea players from the University of the Free State (UFS) formed part of the provisional South African squad for the tournament in Randburg.

The other two not fortunate enough to be included in the final Protea team were Liné Malan and Izelle Lategan.

All five players formed part of the Free State Women’s Team that reached the semi-finals in Division A of the interprovincial tournament for the first time since 1986.

Britz, who is nearing 50 tests for South Africa, will probably play club hockey overseas next year.

Walraven, who was named as South Africa’s U21 Player of the Year, and Botha both made their debut on senior level for their country this year.

Both would probably still be available for Kovsies next year.
