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 more accessible for persons with disabilities
2010-04-22

After millions of rands have already been spent on making its buildings more accessible to people with disabilities, the University of the Free State (UFS) is embarking on a new drive to make the Main Campus more user-friendly for its students and staff with disabilities.

Recently the UFS completed a report with recommendations to upgrade more of its buildings in this regard.

The university is already a leader with regard to its services to students with disabilities and is drawing students from all over the country. The Unit for Students with Disabilities (USD) at the UFS offers support to approximately 120 students.

According to Prof. Niel Viljoen, Vice-Rector: Operations, it remains an ongoing process that should constantly be reviewed. Following a prioritised strategic plan, the UFS is upgrading the bathrooms and elevators in its buildings as well as the ramps and parking spaces.

In the new drive a number of future projects have been identified to make the buildings as well as the Main Campus more accessible and user-friendly for persons with disabilities:

Ramps will be added at the entrances to four more buildings. The entrances to the Geology and Geography Buildings will also be made more accessible. An access ramp from the parking area to the pavement will also be added at the CR de Wet Building (housing the Departments of Physiotherapy and Occupational Therapy).

To make classrooms on higher levels accessible, the UFS is looking into the possibility of installing elevators in four more buildings. The university is also investigating the possibility of stair lifts in two of its buildings. Existing elevators on campus will also be upgraded.

More allocated parking spaces for persons in wheelchairs will also be provided closer to buildings.

Accessible bathrooms for persons with disabilities will be added in five more buildings on campus.
