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.”

In this week of graduation ceremonies, the University of the Free State had more than its academic achievements to celebrate. The Shimlas’ brilliant triumph in the Varsity Cup as well as the achievements by KovsieTennis and Kovsie Netball was celebrated at a colourful event on the Bloemfontein Campus.

At the celebrations, which were well supported by the campus community, the Vice-Chancellor and Rector, Prof Jonathan Jansen, congratulated all three teams on their outstanding achievements. Not only did the Shimlas walk off with the Varsity Cup, they also won every game they played. AJ Coertzen, the Shimlas’ captain, said: “Although we were well prepared and physically fit, the fact that we played for one another contributed much to our success. As a team, we have grown from friends to brothers.”

KovsieTennis was congratulated on wearing the USSA tennis crown for the fourth consecutive year. In addition, they have the following triumphs to their name: 2007 – SASSU (South African Students Sports Union) (Ladies); 2008 – USSA (University Sport South Africa) (Ladies) and 2009 USSA (Men). Duke Munroe, captain of the KovsieTennis team took the opportunity to thank the team personnel. He believes that hard work behind the scenes by the coach, Marnus Kleinhans, and the team manager, Janine de Kock, contributed greatly to the team’s success.

KovsieNetball was also praised for their successes. In 2014, under the captaincy of Karla Mostert, they won gold at the Varsity Netball championships. They also won the National Premier League. The UFS is also proud of its netball players in various national teams: SA Under 19-23, the Protea groups, and the SA University team.

At the celebrations, Karla said: “The environment and the people you surround yourself with dictate how easily you achieve success. Our achievements and successes are evidence of the quality of the coaches, supporters, and facilities available to us.

After the event on the Red Square, the teams made an appearance in the Callie Human Centre, where they were enthusiastically congratulated by graduands, their families and the university management. Dr Khotso Mokhele, Chancellor of the UFS, also praised the teams for their achievements. “You are a team without individual stars. That is the sort of team I want to be part of.”
