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.”

Public Protector visited Faculty of Law
2005-09-23

On 21 September 2005 the Public Protector visited the Faculty of Law.  This event took place at 10:00 in the Senate Hall of the CR Swart Building, after which a light lunch was served for the delegates and staff of the Faculty.

The purpose of the visit was to spell out the roles, functions and powers of the Public Protector, to promote public awareness and transparency and to increase contact between the Faculty and the Public Protector.  Sufficient time was allowed to answer all the questions posed by various parties, and brochures were made available.

All law students and staff members of the Faculty were invited to the occasion.  The presentations also included information regarding career possibilities for students with the Public Protector’s office.  This organization is more than willing to involve students in community service projects and would keep in contact with the Faculty in this regard.

All the representatives of the Public Protector’s office who visited the Faculty are in the law profession:

The following persons made presentations:

Mr P Nthotso:  Independent Complaints Directorate
Ms L Mdalane: Directorate of Special Operations – Scorpions
Ms M Thetlhu: South African Human Rights Commission
Mr A Madiba:  Office of the Public Protector.

The persons mentioned above were accompanied by their supervisors, viz. Mr L Mashee (Head Public Awareness, Free State) and Ms SD Griessel (Provincial representative for the Public Protector, Free State).  A further two employees of the Public Protector attended as observers, viz. Mr T Kgabeginyane and Mr MR Matlesoane.

The Public Protector functions independently and reports directly to Parliament.

Staff and students found the visit very informative and valuable contacts were made in the process.
