The giraffe research programme and infrastructure facility at Amanzi Private Game Reserve marks the next phase in a research journey that has already placed the UFS at the forefront of giraffe science.

The University of the Free State (UFS) is taking wildlife research to new heights. On Wednesday 29 October 2025, the university will officially launch the giraffe research programme and infrastructure facility at the Amanzi Private Game Reserve near Brandfort – a first-of-its-kind in the world, dedicated to advancing local and international scientific collaboration in the study and conservation of giraffes.

The launch marks the next phase in a research journey that has already placed the UFS at the forefront of giraffe science. Over the past decade, a team of researchers, led by Prof Francois Deacon from the Department of Animal Science, has made significant contributions to understanding giraffe behaviour, physiology, and ecology. Building on pioneering work in reproductive technologies, endocrinology, anatomy, and disease, the new infrastructure combines on-site research laboratories with spacious, stress-free habitats. In this hands-on environment, veterinarians, scientists, and students can work closely with giraffes while promoting their welfare and supporting both local and international research projects.

Over the past seven years, his team has conducted 254 successful sedations and captures, carefully building the expertise needed for the next delicate step: the first embryo transfer in wild giraffes.

“This dedicated research facility will provide a safe and controlled environment where the world’s first giraffe embryo can develop and grow, and where we can collaborate to produce the science needed to turn the extinction of the giraffe around,” he explains. “The general public may not see the results immediately, but 20 years from now, what we are doing today will be vital in creating a biobank of viable giraffe embryos and calves that can be used in surrogate animals, supporting sustainable conservation practices for future generations.”

This programme will allow researchers to expand their understanding of the world’s tallest land mammal in ways that were not possible before. “From conducting sedation and sample collection to pioneering reproductive techniques such as semen preservation and embryo transfer, the facility provides an environment where we can study, among others, giraffe genetics, reproductive biology, and physiology; knowledge that is important for their conservation and survival,” says Prof Deacon. 

About 12 departments at the UFS are already involved in the research project in one way or another. This includes from the Department of Animal Science to the Departments of Zoology and Entomology, as well as Chemistry and even Information and Communication and Technology Services, which contributes to 3D-modelling, software, and monitoring of the animals. 

The project also offers opportunities for collaboration with conservation organisations and universities worldwide, positioning the UFS as a leading hub for giraffe and large-mammal research in Africa. Current partners who share Prof Deacon’s vision for giraffe conservation on the African continent include Save the Giraffes (a US-based NGO), Absolute Genetics, Ramsem, and the Kroonstad Animal Hospital.

Despite their towering presence on the African continent, giraffes are quietly disappearing. The International Union for Conservation of Nature (IUCN) lists them as Vulnerable, with populations declining by more than 40% over the past three decades. Today, fewer than 100 000 remain in the wild – a sobering reminder that their future is far from secure and that research excellence like this is key to ensure their survival.

“We have all the technology and all the expertise to make a change. Now is the time to bring about this change to secure the future of giraffes on this continent,” Prof Deacon concludes, emphasising the UFS’ commitment to sustainability, care, and conservation.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
