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.”

Forensic investigation at UFS Computer Services division in final stage of finalisation
2007-02-01

Statement by prof Niel Viljoen, Chief Director: Operations  
 
The case in which possible irregularities were investigated at the University of the Free State’s (UFS) Computer Services Division at the end of 2005, and which led to two Deputy Directors’ compulsory leave pending an investigation, is making good progress and is in the final stage of finalisation.
 
One of the Deputy Directors resigned unconditionally a day before his disciplinary hearing was to take place. He is one of two staff members who were placed on compulsory leave after an internal investigation ordered by the UFS management indicated possible irregularities in the division.
 
“As a result of the extent of the case and the involvement of more than one local business, the investigation had a long course,” said Prof Viljoen.
 
“The Deputy Director who resigned would have appeared before a disciplinary committee with Judge Joos Hefer as chairperson on charges of misconduct, involving more than R500 000,” said Prof Viljoen.
 
“We are going ahead with the process of criminal prosecution against this person and a docket was opened at the commerce branch of the South African Police Services (SAPS).  A civil action to recover damages from him was started,” Prof Viljoen said.
 
With a couple of exceptions, the internal disciplinary process of the other persons involved in the case is also finalised. “The disciplinary hearing of the Deputy Director, who is still in the service of the UFS’s Computer Services division, is scheduled for May 2007. This person is still on compulsory leave,” Prof Viljoen said.
 
“To demonstrate our commitment to the enhancement of honest work ethics and to give to personnel and students a mechanism to bring any unethical business practices to the attention of the UFS management, a fraud hotline was installed last year. The hotline is operated 24 hours a day for 365 days of the year by KPMG,” Prof Viljoen said.
 
Prof Viljoen thanked everyone who was involved in the investigation for their cooperation. This includes staff as well as people from outside the UFS.  “We are committed to transparent corporate management. Any possible irregularities will be investigated and if staff or students are found guilty of any irregular behaviour, strict actions would be taken against these persons,” Prof Viljoen said.
