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.”

Statement following a protest march on the Main Campus

Statement by UFS management following a protest march on the Main Campus

A protest march by a small number of SASCO members took place at the University of the Free State’s (UFS) Main Campus in Bloemfontein today (Wednesday 6 September 2006).

At the end of the protest march a memorandum was handed to the Dean of Student Affairs, Dr Natie Luyt.

The UFS Management remains committed to provide quality education to all students at the UFS. The management is also committed to the transformation of the campus and to creating a non-racial, multilingual and multicultural student life.

It must be remembered that certain processes are already in place to address some of the issues raised, such as a Transformation Plan Task Team, which is in the process of drafting a comprehensive transformation plan for the UFS.

Discussions are also already taking place between management and student structures, including SASCO, about certain issues raised in the memorandum.

However, the management will respond to the memorandum using the appropriate channels that exist on campus to communicate with all student formations, including SASCO.

The UFS management wishes to thank the SASCO members for the peaceful and non-violent way in which the protest march was conducted and for which the management had granted SASCO permission.

The UFS management appeals to SASCO to make use of the channels that exist to address the concerns of their members and find workable solutions in the interest of a quality university and quality student life.
