The research team helps a giraffe to get up after they have finished collecting data.

Researchers from the University of the Free State (UFS) hope their research to investigate why some animals prefer or avoid some habitats, will also create awareness for the plight of giraffes which have lost more than 80% of some of their subspecies in East Africa and are facing extinction in the wild.

Dr Marietjie Schutte-Smith, Senior Lecturer in the Department of Chemistry, says the collaborative research being done in South Africa is very unique and could help save subspecies from the brink of extinction – as South Africa has managed to double its giraffe numbers whilst subspecies have declined tremendously.

Why some animals prefer or avoid some habitats

“By using modern analysis techniques and instruments (such as drones and GPS devices), it is possible to study complex environments on a spatial ecology scale and has created the opportunity to investigate why some animals prefer or avoid some habitats,” explains wildlife expert Dr Francois Deacon.

“This in turn opened the door to explore geographic, soil and nutritional qualities the giraffe might prefer or avoid. This is one of the main reasons we are exploring the different factors and driving forces behind a large herbivore’s habitat selection, well-being, body condition parameters and physiological adaptations,” Dr Deacon says.

Veld conditions, plant species composition, tree densities and other available resources such as production yield and water quality determine reproduction successes and how animals disperse, move and distribute over an area. Spatial and ecological distributions of giraffe specifically depend on habitat resources and qualities that in turn affect their complex behavioral tactics and survival.

Strange habits

The research was started back in 2010 by Dr Deacon and Prof Nico Smit from the Department of Animal, Wildlife and Grassland Sciences at the UFS with the pioneering of GPS devices to investigate giraffe spatial ecology and habitat use. The current study was initiated as to why the giraffe would utilise one area more than the other, even if the two habitats had the same tree species, says Dr Schutte-Smith.

Dr Deacon contacted Prof Hendrik Visser and Dr Schutte-Smith from the Department of Chemistry for a possible collaborative effort. Ms Jeaneme Kuhn started her MSc research degree on this project in January 2019 and completed her degree in August 2020 with distinction.

Dr Schutte-Smith says from research done at Rooipoort Nature Reserve it was found that a certain group of giraffes had the strange habit of only eating from specific trees, avoiding similar trees a few metres away. “We wanted to see if this behaviour was due to chemical influences, i.e. if there are specific minerals that are possibly in excess at some places which they avoid, especially since there are mines close by.”

Aim of the research

The main aim of this MSc Chemistry degree, according to Dr Schutte-Smith, is to validate an analytical method for testing leaves and soil samples, using IPC, to see if heavy metals (in excess) are present in the soil, leaves and water and whether this has an influence on the browsing pattern of the giraffes. “Then as secondary aims (for the collaborative effort) we would like to investigate if the giraffe can select one area above the other (core home ranges), to understand what the qualities are that they would select for in the preferred area and what the qualities they avoid are in the other. And lastly to understand what the minimum requirements are to keep the animals happy and healthy, but also to investigate how they search for these qualities,” says Dr Schutte-Smith.

Giraffe conservation

Besides creating awareness of the plight of giraffes, the researchers also aim to create a model for conservation via research and education to be used as an example for other countries. This model incorporates students, academia, professionals, sponsors and stakeholders that cover various topics relating to giraffe education, management and conservation.

They would also like to see the UFS as the institution that has contributed the most to giraffe conservation strategies in Africa by being the leading university in the collection and analysis of information about giraffes and their habitats, increasing conservation education awareness about giraffes and African biodiversity and to develop national and/or regional plans aimed at giraffe conservation.

The research team successfully applied for funding which they used for chemicals and solvents to perform testing as well as sampling.

Politicians must push economic integration within SADC, Mboweni
2009-08-31

The outgoing Governor of the Reserve Bank, Mr Tito Mboweni (pictured), believes that for economic regional integration to be realized among the Southern African Development Community (SADC) countries, the political leadership of the region should play a pivotal role.

Mr Mboweni delivered the CR Swart Memorial Lecture, the oldest lecture at the University of the Free State, on the topic: “Seeking greater political and economic integration in Southern Africa in challenging and turbulent financial times”.

He said the necessary macro-economic convergence accords must be put in place for regional integration to take place.

These accords, he said, should be supported by prudent fiscal policies, financial balances among SADC countries, and the implementation of policies which will minimize market distortions.

“In the crafting of the macro-economic policies of the region we have to ensure that market certainty is maintained,” he said.

He said as governors of central banks in the region they have agreed that to achieve these objectives they first have to attain a free trade area.

“When the proposals were drafted the idea was that in 2008 we should have achieved a free trade area,” he explained. “Now we are behind in that regard, meaning that a free trade area has been formally and officially declared but the implementation thereof is behind schedule.”

Mr Mboweni said they were supposed to have a SADC-wide customs union in 2010, a SADC common market in 2015 and a monetary union in 2016.

“In order for us to move towards the regional integration agenda it is clear that there has to be a far greater intra-African trade than is the case now,” he said.

“In Southern Africa most of the trade is with South Africa and the other countries do not trade much with or amongst each other.”

He also said because the South African currency is legal tender in countries like Lesotho, Namibia and Swaziland, they have developed a comprehensive set of proposals with these countries to deal with this matter.

“Our proposals basically center on the creation of a common central bank for South Africa, Lesotho, Namibia and Swaziland which, if created, would form a good basis for the establishment of a SADC-wide central bank.”

He said the macro-economic convergence criteria will not help achieve regional integration without the region’s political will.

“There has to be a commitment by the political leadership in Southern Africa to do the basic things that need to be done for the development of the region,” he said.

“That is where the notion of a developmental state must come in in support of these regional integration initiatives. There is no gain in just shouting developmental state if the basic issues supportive of development are not done.”

Mr Mboweni will leave the Reserve Bank in November this year.
