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.”

UFS Qwaqwa campus sets deadline for applications
2004-11-11

The University of the Free State’s (UFS) Qwaqwa campus is preparing for the first round of applications for admittance to study in 2005. The closing date for applications is 30 November 2004.

“This applies to first-year students, senior students who have interrupted their studies for at least one year and undergraduate students from other educational institutions,” said Mr Vernon Collett, Registrar: Academic Student Services at the UFS.

According to Mr Collett, all applications that are received after 30 November 2004 and up to no later than 1 February 2005, will be regarded as pending.

“Since student numbers are now limited by government policy and depending on availability in educational programmes, these applications will be subject to consideration by the relevant dean,” said Mr Collett.

Prospective students who want to apply must pay a non-refundable fee of R100 into a designated account, which will be provided when the application form is sent to them. The signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport and a proof of payment of the application fee. The application form of a minor must be signed by his/her parent or guardian and the field of study should be clearly indicated.

“A total of 2088 students are registered at the UFS’ Qwaqwa campus this year. We expect a considerable amount of applications and foresee that our numbers for next year will be similar to what it is now,” said Mr Collett.

First-time entering first-year students will be welcomed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie, on 15 January 2005 at 11:00 in the Nelson Mandela Hall on campus.

Prospective students who want to apply or who have any enquiries can call (058) 718-5000 or visit the UFS’ Qwaqwa campus web site at www.uovs.ac.za.
