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 launches unique project to honour great teachers
2011-04-21

Dedicated, hard-working, inspiring and motivational ...

These are the kind of teachers the University of the Free State (UFS) is looking to honour in their Great Teachers Project.
 
When one is confronted by most images of teachers in the mainstream media, these are rarely the words that come to mind, though. However, for many young men and women these are exactly the traits which they saw in their teachers, and which inspired them to become South Africa’s next generation of poets, painters, architects, mathematicians, drummers, pilots, lawyers, philosophers, doctors, accountants, community developers and more.
 
One rarely hears about the truly great teachers from our past and present who are the driving force behind the successes of many of our greatest achievers. The teachers who go the extra mile to convey the intricate beauties within their subjects, lead an exemplary life and produced the activists, critical thinkers and leaders we all cherish.
 
Therefore, the UFS and the Sunday Times have joined hands in identifying 150 of the greatest teachers, who moved, inspired and transformed South Africans during their time at school. These are the teachers who stood out among their colleagues and made a lasting impact on their learners, inspiring them to excel, long after the mathematical equations and English literature tests are forgotten.
 
The stories will be collected and assembled on a central database and categorised, edited and represented into a coherent array of powerful accounts of inspired and inspiring teachers.
 
A book entitled Great Teachers will be published in December 2011, detailing the stories of these great individuals. The introduction to the book will present the plan and process that led the storied collection.
Those who are interested are invited to submit a 500 to 750 word essay on any teacher who made an impact in their life and submit it to greatteachers@ufs.ac.za before 30 May 2011.
 
All proceeds from the sales of the book will be used to provide bursaries to student teachers of today, who may become the great teachers for tomorrow’s generation.
