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 academics work on text book about legal requirements for cultural institutions
2010-11-09

Prof. Johan Henning, Dean of the Faculty of Law, UFS; Prof. Loot Pretorius, also from the Faculty of Law; and Mr Tokkie Pretorius, Director of the War Museum in Bloemfontein.

A team consisting of Prof. Johan Henning, Dean of the Faculty of Law at the University of the Free State (UFS), Prof. Loot Pretorius, also from the Faculty of Law, and Mr Tokkie Pretorius, Director of the War Museum, is going to tackle a project which will focus on the new legal requirements for cultural institutions, with special reference to national museums.

Previously this team has written a textbook on the legal position of development corporations, which is regarded as a standard work about this topic.

Museum managers often come from the expert conservation and research environment and find it difficult to comply with the new legal requirements pertaining to national museums.

National museums, amongst which counts the War Museum of the Boer Republics, are classified by the Public Finance Management Act (PFMA) no. 1 of 1999 as Public Entities.

This Act also states specific accounting requirements regarding the accounting standards, year-end statements and the auditing process on the one hand, but on the other hand specific requirement with regard to corporate management.

The King II Report and it most recent extension, King III, sets specific guidelines to be followed in the managerial process and specifically emphasises the role and responsibilities of non-executive boards of directors (board members) and those of the executive director (chief executive officer). The Cultural Institutions Act, no. 119 of 1998, regulates the operation of national museums, amongst others the constitution and functions of the boards of national museums. Various other forms of legislation also apply to national museums.

According to Prof. Pretorius they aim to publish the book within the next 18 months.
