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.”

Students have a responsibility in SA, says Ntuli

You and I have a role to play in building the new South Africa built upon the Constitution of 1996.

These are the words of Lindokuhle Ntuli, President of the Student Representative Council (SRC) on the Bloemfontein Campus of the University of the Free State (UFS). They echo his and the SRC’s message of a “campus for all students, locally and internationally, irrespective of colour.”

Ntuli and Paseka Sikhosana, president of the SRC on the Qwaqwa Campus, were in agreement about their vision for the UFS in 2016.

According to Sikhosana, a well-known slogan accentuates a feeling of uniqueness at the university. “United in diversity. No wonder we say only a Kovsie knows a feeling,” he says.

“As the SRC, we believe that complete transformation on campus is through promoting a non-sexist, non-racial, but democratic student society that acknowledges diversity and change. That further promotes and embraces one student’s difference in terms of culture, tradition, religion, and sexual orientation.”

A new South Africa

Ntuli means students have a responsibility. He referred to a quotation from Frantz Fanon’s book, The Wretched of the Earth, to illustrate this. Fanon was a revolutionary and writer whose works are influential in post-colonial studies. “Every generation has a mission. It is the responsibility of every generation to discover its mission. Once you have discovered it, you have to fulfil it or betray it into relative obscurity,” Ntuli quoted.

According to him, the South African Constitution holds pious promises of a better life for all, and each citizen needs to help to achieve that.

SRC has open door policy 

Ntuli says the UFS remains committed to human embrace, diversity, integration, and human togetherness. He added that the SRC has an open door policy, and will avail itself in helping students.

According to Sikhosana, it is the objective of the SRC to represent the student community in all interactions within the university and externally.

“There is nothing for us, about us, without us students,” he says.
