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 management praise dean for achievement
2004-08-17

 

 

Prof Letticia Moja was praised by Prof Frederick Fourie, Rector and Vice-Chancellor of the University of the Free State (UFS), and other members of management today for winning the education category of this year’s Shoprite Checkers/SABC2 Woman of the Year Award.

“We are extremely proud of Prof Moja with this prestigious achievement. It is also a feather in the cap for the UFS that our leaders are being recognised on a national level,” said Prof Fourie.

Prof Moja was appointed as Dean of the Faculty of Health Sciences at the end of last year, becoming the first woman to be appointed in this position at any medical faculty in the country.

“Prof Moja was nominated by her colleagues at the faculty. It is heart-warming to me that she made such an impact in the faculty in the short period since she was appointed as dean to be nominated for this prestigious award,” said Prof Fourie.

“On the nomination form, her colleagues wrote: ‘Prof Moja is not only a remarkable woman, but also a person with gifted qualities of leadership, dedication and compassion. She is blessed with the ability to listen to others, is an extremely reliable person and a competent leader’ – this makes her, in my view, a true winner”, said Prof Fourie.

Prof Moja was recently chosen as vice-president of the Health Professions Council and also serves on the Medical and Dental Board. Her involvement in these councils and committees enables her to represent women in general, as well as previous minority groups.

Prof Moja headed the Gynaecologic Oncology Unit at the Ga-Rankuwa Hospital in Pretoria from 1997 to February 2002, where after she was appointed as Vice-Dean at the UFS’s Faculty of Health Sciences and at the end of 2003 she was appointed in her current position. During her career, she has attended four international and eight local congresses, presented eight oral papers and four posters, was an author to one publication, co-authored four publications, was a guest editor to one publication and supervised three postgraduate publications.
