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.”

UV Voices Kamerkoor by die KKNK

Membra Jesu nostri – Buxtehude (1637 – 1707)
 

Membra Jesu nostri patientis sanctissima (Die allerheilige liggaam van die lydende Jesus aan die kruis) deur Buxtehude het die Kruisiging van Jesus as tema.

Die uurlange werk word in Latyn gesing en handel in elk van die sewe dele oor ‘n deel van Jesus se liggaam aan die kruis: voete, knië, hande, die sy, bolyf, hart en gesig. Voices Inc – Kovsie kamerkoor word bygestaan deur die Odeion Strykkwartet met Francois Henkins, Abrie de Wet, John Wille en Michaela Haller. Die kontrabas word deur Alba Henkins-Molller bespeel en Jan Beukes is die orrelis.

Die woorde in Latyn wat buitengewoon was vir ‘n werk deur Buxtehude, is geneem uit die Latynse Bybel (Vulgate) en van die Rhytmica Oratio Sancti Bernadi, ‘n strofiese gedig deur St Bernard van Claivaux (c1090 – 1153).

Die wyse waarop Jesus se pyn aan die kruis uitgebeeld word asook die gebed en uitroep van versoening tussen God en die mensdom was deel van die Piëtiste se oortuigings van die tyd.

Die werk is saamgestel uit sewe afsonderlike dele wat telkens deur ‘n instrumentale sonate aangekondig word. Die koor lui die vokale bydrae in en sluit elke deel ook af. Die res van die werk bestaan uit verskillende groeperings van solo’s en trio’. Interessante vokale kombinasies kan gehoor word, bv. twee soprane en bas asook sopraan, alt en tenoor.

Hierdie opwindende aanbieding van Membra Jesu nostri, ‘n juweel uit die Baroktydperk, word aangebied deur ‘n groep energieke studente van Kovsies. Die jeugdige klank van die soliste – almal studente aan die Universiteit van die Vrystaat - dra by tot die egtheid van die Barok-klank. Die koor staan onder leiding van Leona Geldenhuys, dosent in Koorleiding aan die UV.
