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.

Call for nominations for the Chancellor’s Distinguished Alumni Awards
2017-06-23

Description: Chancellor’s Distinguished Alumni Awards 2017 Tags: Chancellor’s Distinguished Alumni Awards 2017


The University of the Free State has produced a crop of excellent alumni who have placed the university on the world stage. The aim of the third annual Chancellor’s Distinguished Alumni Awards is to acknowledge and honour alumni for achievements in both their personal capacity and occupational fields. Recognition for the 2017 Chancellor’s Distinguished Alumni Awards will be based on achievements attained from 2016 to 2017.

Nominations are invited in five categories:
•    The Chancellor’s Distinguished Alumnus of the Year Award, the highest honour accorded to an alumnus, recognises the distinguished national or international achievements of its recipient.
•    The Young Alumnus of the Year Award acknowledges the achievements of alumni who have graduated within the past decade.
•    The Cum Laude Award is bestowed upon an alumnus to recognise excellence in any field.
•    The Executive Management Award is made to any person (not necessarily an alumnus) who has delivered exceptional service to the university.
•    The Kovsie Ambassador Award is bestowed upon a current student whose achievements have brought distinction to him/her, benefited his/her community, and brought credit to the University of the Free State.

Previous recipients of the Chancellor’s Distinguished Alumni Awards include television personality, Leon Schuster; Free State Education MEC, Tate Makgoe; politician, Adv. Roelf Meyer; Olympic gold medallist, Wayde van Niekerk; former Miss World, Rolene Strauss; CEO of Central Media Group, Gary Stroebel; and Judge President of the Free State High Court, Justice Mahube Molemela.

Nominations can be submitted in writing to the Alumni Office at alumni@ufs.ac.za using the provided nomination form. A selection panel will choose the appropriate candidate(s) with age, race, and gender playing no role in the selection process. The closing date for submission of nominations is 12:00 on 31 July 2017. Award winners will be announced at a gala banquet on Saturday, 26 August 2017.

Additional queries can be directed to Helen Namponya at +27 51 401 9343, or by email at alumni@ufs.ac.za.
