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.

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
