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.”

Kovsies hoist the rainbow flag to show support for International Day against Homophobia and Transphobia

Violence and discrimination against the Lesbian, Gay, Bisexual, Transgender, and Intersex (LGBTI) community is rife in South Africa. Advancing the spirit of the University of the Free State’s (UFS) Human Project, Out@Kovsies and the Institute for Reconciliation and Social Justice (IRSJ) showed their true colours by hoisting the rainbow flag in front of the Main Building on the Bloemfontein Campus.

International Day against Homophobia and Transphobia

This event was in anticipation of International Day against Homophobia and Transphobia celebrated on Sunday 17 May 2015. People across the world, regardless of their sexual orientation, come together annually on this day in support of the LGBTI community. This year, Kovsies became part of that global community when, for the first time in history, the rainbow flag –  a popular symbol of LGBTI pride – fluttered high over the Red Square.
 
Human embrace

Committed to the human embrace, this event was another decisive step towards true transformation. “Transformation is not about black or white anymore,” said Zanele Thela, coordinator and guardian of Out@Kovsies, during the event. “It’s about including different diversities, different sexual orientations.”

Laura-Jane Watkins, research assistant at the IRSJ, said that this day “reflects our attitude as a collective community to embrace difference. Today is a day that we reaffirm diverse expressions of love beyond societal perceptions of gender as an inherent human need and right. Let us now stand together as a student community to promote the value of humanness.”

Rainbow flag

The rainbow flag, also fondly known as the freedom flag, was designed by civil rights activist, Gilbert Baker, and was hoisted publically on 25 June 1978. The modern version of the flag consists of six colours, each with a specific meaning. Red stands for life, orange for healing, yellow depicts sunlight, green stands for nature, blue for serenity, and violet for spirit.

The hope that Thela holds is for everyone to be free to express themselves and their love for one another, because “that’s the one thing we all have in common: love”.
