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.”

Voter turnout during the recent SRC elections among the best in the country at over 60%

The 2016-2017 Qwaqwa Campus SRC elections have once again proven that democracy and political tolerance are truly thriving on the Qwaqwa Campus. This was evidenced by the calm surrounding the highly contested elections ever.

According to Mandla Ndlangamandla, Electoral Committee Chairperson, this year’s elections were highly contentious, yet with a high level of tolerance.

"We only had two political structures, namely the South African Democratic Student Movement (Sadesmo) and the South African Student Congress (Sasco), but the level of engagement was really commendable,” he said.

“Of the 4 200 registered students on campus, more than 2 500 cast their votes in their quest to influence student leadership and governance to advance student aspirations," said Ndlangamandla during the handover ceremony.

In accepting the leadership baton from his predecessor, Paseka Sikhosana, the new President, Njabulo Mwali, said his immediate goal was to unite all students behind the new leadership.

In acknowledging the role student governance can play in developing the campus, the Acting Campus Principal, Teboho Manchu, said the campus was proud to have a student leadership that would always keep the interests of their constituency on top of their agenda.

“We will definitely work hand-in-hand with the new student government. In case of any disagreements, please note that you have the right to take up any such matters with the top management of the university in order to advance the entire student body,” he added.

The 2016-2017 Qwaqwa Campus SRC is as follows:
