Rhino Conservation
Should the ban on trade in rhino horn be lifted and South Africa could generate financial incentives, a large percentage of the funds should be allocated towards the conservation of the Java, Sumatra and Indian rhino.

Water, cold, thirst, volcanoes …. and poaching, are causing the death of rhinos across the globe. 

Recently, a group of scientists and rhino activists met at the University of the Free State (UFS) to discuss the plight of rhinos in South Africa. Bringing an international perspective to the colloquium on global rhino conservation, were three delegates from Indonesia who are working with the most endangered rhinos on earth – the Javan and Sumatra rhinos. 

Dr Rudi Putra, a biologist, received a Goldman Environmental Prize in 2014 for his efforts to save the Sumatra rhinos – of which an estimated 65 individuals are left in the Gunung Leuser National Park. Muhamnad Syamsudin is responsible for a 30-person rhino protection unit, which has not lost one rhino to poaching in Ujung Kulon National Park in 19 years. The third person from the Indonesian delegation was Dr Firmanto Noviar Suwanda, a lead scientist in rhino observation data, with a 30-person rhino monitoring unit, also in Ujung Kulon National Park.

Also presenting at the colloquium, were researchers from an inter-disciplinary team at the UFS, who are working together to establish a rhino conservation model through research and teaching.

The colloquium was convened by the UFS.

Rhino revolution 

According to Dr Willem Daffue, a veterinarian from Kroonstad, the world needs a rhino revolution. “What we have been doing, is not working,” he said.

South African rhino farmers own almost half of the rhino population in the country. Dr Daffue shared facts on rhinos introduced to private captivity. “In the beginning, the animals died of thirst (the white rhino cannot lift its head to drink from a water trough), cold, and killing each other. And then poachers killed them …”

In 2009, South Africa saw an unprecedented spike in horn poaching, resulting in CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) implementing a ban on the sale of rhino horn within South Africa. The international sale of rhino horn – in an attempt to halt the unrelenting slaughter of rhinos in Africa and Asia – was already banned by CITES in 1977.

Role players agree that banning the trade in rhino horn is not the answer. The status quo is not working. 

For two weeks after the colloquium, Dr Deacon, Dr Daffue, and the Indonesians met with several role players in the rhino industry, including Dr Jana Pretorius (Rhino Pride Foundation), who established immediate, practical preventative measures to protect rhinos from poachers. Other people who were visited, were Dr Johan Marais (Saving the Survivors) who is tending injured endangered wildlife that have fallen victim to poaching, as well as Dr Danie Pienaar and Dr Markus Meyer (SANParks scientific services in the Kruger National Park’s Skukuza headquarters). They also knocked on the doors of Anton and Clive Walker (authors of Rhino Revolution) as well as Petronel Nieuwoudt (Care for Wild Rhino Sanctuary NPC), who is one of the few people worldwide who specialise in the care of orphaned rhinos.

“All role players feel that if they could sell the horns, they could easily afford to keep the animals secure.  And the horns are harvestable. We just trim them – as with sheep's wool. They grow back at up to 10 cm (4 inches) a year,” explained Dr Deacon. 

“Decision making, specifically about legalising the trade in rhino horn, needs to change. Involved parties feel that countries must decide, or more specifically, the role players in the industry – people with a responsibility towards the animals. It must not be up to CITES,” he said.

Safety for all rhinos


CITES met at the same time that the UFS team hosted the Indonesian party. “The timing of the trip was perfect, because CITES and the ban was being discussed. The status quo remains, however, as the ban on rhino-horn trade was not lifted,” said Dr Deacon.”

“It became apparent – we simply will not allow trade of South African rhino horn if we cannot secure the wellbeing and a safe haven for the Java, Sumatra, and the Indian rhino. We strongly discourage any sort of trade if one species is favoured while the others are facing a dark future,” stated Dr Deacon.

They proposed to different stakeholders that, should the ban on trade in rhino horn be lifted and South Africa could generate financial incentives, a large percentage of the funds should be allocated towards the conservation of the three Asian rhinos.

More research

At the UFS, the interdisciplinary team is continuing to work on research to breed a hardened animal through the project ‘Ecological and biological factors regulating rhino in captive environments.’ They are in the process of collecting data from 750 rhinos across South Africa. Several members of the team presented at the colloquium. 

Prof Paul Grobler from the Department of Genetics informed attendees on the role of genetics in rhino protection, focusing on touch DNA. He said it only takes seven to eight cells to amplify touch DNA that could link a perpetrator to a crime scene. With rhino poaching, touch DNA can be applied on the skin of the animal by collecting skin cells with tape lifting or swabs. 

Rolene Grobler, also from the UFS Department of Animal, Wildlife and Grassland Sciences, talked about how research on IVF, surrogacy, and cryopreservation of semen and embryos could be considered to save the rhino. 

Dr Hennie Butler from the UFS Department of Zoology and Entomology specifically focused on the behaviour of rhinos after dehorning or trimming of the horns. “Losing their horns will have an effect. Research has shown that the animals are more stressed, affecting birth rates, a change in habitat, and their social behaviour within bigger groups.” 

Also talking at the colloquium, were Dr Frans O'Neill, who focused on the cholesterol of the animals, and Dr Gary Osthoff, who looked at the milk production of the animals.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
