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.

Course on sustainable development recognised at COP 17
2011-12-07

 

Some participants of the PED Nexus Programme during a field trip are from left: Jacques van Zuydam, Chief Director: Population and Development at the national  Department of Social Development; Prof. André Pelser, course coordinator (UFS); Prof. Sosten Chiotha, Director, LEAD Southern and Eastern Africa; and Dr Nola Redelinghuys, course facilitator (UFS).

The University of the Free State (UFS) received a nod of approval at the COP 17 Climate Change Conference in Durban for a short course it presents in partnership with the Chief Directorate Population and Development, United Nations Populations Fund (UNFPA), LEAD International and SANParks.

The UFS received an honourable mention in a press release from the Department of Social Development for the short course entitled ‘Leadership Training in Sustainable Development: The Population, Environment and Development (PED) Nexus’. The release was issued as part of COP17. It mentions that the course is recognised in a publication of the United Nations Development Programme (UNDP) as one of ten innovative experiences and best practices in population and development in the developing world.
 
Prof. André Pelser, UFS Professor in Sociology, says the university played a key role in the development and implementation of the course. The UFS has been presenting the course since its inception in 2005.   Similar courses under the banner of the PED Nexus, although in a totally different format, are also presented at the Nelson Mandela Metropolitan University and the University of Cape Town. A total of 21 courses have been presented nationwide since 2005, of which the UFS has hosted eight. More than 230 participants from all over the world have been trained in these eight short nine-day courses.
 
The PED Nexus Programme focuses on the interrelationships of population, environment and development and its significance for sustainable human development and is closely linked to the implementation of the national Population Policy for South Africa. The press release reads that the programme is implemented in the form of short courses that target professionals and managers in governments at all levels as well as non-governmental agencies responsible for the implementation of programmes related to sustainable development.
 
Prof. Pelser and Dr Nola Redelinghuys, also from the Department of Sociology, have recently been tasked by the National Department of Social Development to upgrade the course outline.  The next course will run from 17-25 April 2012. As in the case of pervious courses, the first six days will be hosted on our main Campus in Bloemfontein, whereafter course participants and their facilitators depart to the Golden Gate Highlands National Park for the practical part of the course.
