Let's hear it for hippos - fish feeders of the Olifants!


Sausage Tree Safari Camp • April 5, 2024

The debilitating drought that ended five years ago saw the Kruger National Park lose almost half of its hippo population, with an estimated 4000 of these water-dependent animals dying, not as you'd imagine, from a shortage of water, but due to a shortage of food.


Drought always hits hippo populations hard as they depend on good grazing when they leave the safety of the water at night, travelling up to 20km away from the water to feed mostly on grasses. They can consume up to 50kg of grass in one night, acting like a biological lawn-mower.



Here in the Olifants Nature Reserve, Greater Kruger, whilst we didn't lose thousands of hippos, we did notice a significant drop in numbers during the drought, as with most of our larger herbivores. Thankfully numbers are now recovering nicely, which is good for the Olifants River and the other water sources on the reserve.


Hippos are critical for healthy rivers for an unusual reason - their poop. Hippo dung provides valuable nutrients for fish and other aquatic species, so when you see a hippo defecating in the water, think positive thoughts! However, as with any good thing, too much of it can cause problems. When water sources like dams and seasonal rivers shrink, too much hippo dung can prove toxic to aquatic life, primarily because of the absorption of dissolved oxygen.


Hippos spend their days in the water, and can move through it quite rapidly when they need to. They're not good swimmers, but generally walk or run along the bottom of rivers or dams, surfacing every three to five minutes to breathe. They can sleep underwater too, thanks to the process of surfacing to breathe being a subconscious one.


Hippos are trailblazers. Literally. They have an enormous impact on the land surrounding river systems and dams as they generally take the same paths each night to feed, clearing vegetation and creating hard surfaces as they constantly move across the ground. These paths are followed by other animals as they offer direct access to water.


Hippos are very dangerous due to high levels of agression, most especially in bulls which are extremely territorial. They are also exceptionally nervous and when out of the water will seek to escape to it when startled or alarmed. Their bite can be fatal, thanks to their long, sharp incisors and canines which brush past one another in a scissor action, plus their incredibly powerful jaws.


Territorial bulls preside over a relatively small stretch of river, or waterholes and dams. In its territory a mature bull will dominate a pod of females and babies, as well as juveniles and younger bulls which are allowed to stay in the pod as long as they remain submissive. Territories primarily exist to establish mating rights with the females and fights between bulls invariably revolve around dominance.


Before coming to blows, bulls will gape at one another, opening their huge mouths to almost 180 degrees, showing off their canines and incisors in a threat display. The incisors point forward, like tusks, and can reach up to 40cm in length. The super-sharp canines can grow up to 50cm in length. They are used in combat and play no role in feeding.

A hippo's skin has very little hair. It is also very sensitive to the sun, which is why hippos prefer to stay submerged during the hottest periods of the day. They secrete a red-coloured oily substance that acts as a natural sunscreen, but they still need to stay in the water as much as possible as too much exposure to the sun causes their skin to crack.


Hippos are very vocal animals and are able to communicate above and below the water at the same time. They achieve this courtesy of a fatty area around their necks which vibrates when the hippo vocalises through its nose, sending the sounds waves out into the water at the same time. The sounds are amplified by the water and can be heard over large distances, and express important information like "this is my territory" and "I am here, so stay away".


Here at Sausage Tree Safari Camp we love for our guests to experience the sounds the hippos make, which always remind us of someone guffawing at a particularly rude joke!

It is a very rare sighting indeed and a few days ago very lucky guests staying at Sausage Tree Safari Camp here on Olifants West Nature Reserve had a very close up view of an unusually relaxed mother and cub.

We were privileged to attend a lecture on Pangolins given by Professor Raymond Jansen of Tswane University, predominantly for the benefit of our Black Mamba all female, anti poaching environmental monitors, at their Operations HQ here on Olifants West Nature Reserve in the Greater Kruger To write that it was fascinating would be a significant understatement . The professor opened up with a banger : the 8 species of pangolin are in the unique order of Pholidota . The closest order is Carnivora! In fact medical treatment for pangolins follows along the same lines as for domestic cats. The pangolin has been traced back 85 million years to an ancestor fossil found in Germany, a relic from Pangea times. The pangolin is the only mammal to be covered in scales which are made of keratin, the one and the same substance as our fingernails and the horns of rhino. It is also unique for an African mammal, bipedal. The four Asian species are perilously close to extinction and the four African species are heading the same way. Two of the four African species are arboreal, the white bellied pangolin ( the most frequently encountered) and the black bellied pangolin. The rarest is the Giant ground pangolin weighing in at a staggering 44 kilos plus. These three species are predominantly found in Central and West Africa. The Temmincks ground pangolin weighing in between 6 to 14 kilos is the the most widespread species and is the one that if you are incredibly lucky, can be found in our area. Many a field guide has spent years in the field without ever having seen a pangolin. They are solitary and nocturnal and feed only on ants and termites using a tongue which is as long as their entire body attached to their sternum, which when not in use curls up within the abdominal area. Ground pangolin mortality has for many years been caused by electric fences when they walk unwittingly into one with the bottom strand being live, and on contact triggers their defence mechanism whereby they curl up into a ball and die of electrocution. Wandering onto roads and becoming roadkill is another. Traditional medicinal use in sub Saharan Africa is another as the scales are considered to have healing powers to treat a host of serious to minor ailments. However field research conducted by the Professor’s students found this to be possibly sustainable as a traditional healer attested to needing just two scales a year for grinding down into potions for an entire village. However the other traditional use of gifting a pangolin to tribal chiefs and elders as the most prestigious gift that can be made, is not sustainable and is said to be the reason why pangolins can no longer be found in KwaZulu Natal. In West and Central Africa traditionally pangolin have been hunted for their meat and openly and legally sold on the side of roads at around $20 per animal. The scales having no perceived medicinal or cultural value were discarded as waste. In more recent times the arrival of Chinese doing business in Africa has dramatically altered the pressure on the African pangolin. There has been a very longstanding tradition of using pangolin scales in traditional Chinese medicine and with the demise of the Asiatic species the illegal trade in African pangolin scales has rocketed. 90% of African scales are estimated to be China bound where they are eventually sold at very high prices and 75% of the trade is routed through Nigeria . Here in South Africa , our province of Limpopo has become a hotspot for pangolin poaching. The professor reports that entire containers full of scales have been confiscated in Hong Kong which represents a staggering number of pangolin poached. Efforts by a relatively recently formed pangolins anti poaching unit which includes members of the Hawks special unit of the South African police due to the Nigerian organised crime involvement has resulted in 267 arrests to date and recent sentences have risen to eight years. Hopefully this sends a strong message out, discouraging people from entering the illegal trade. Recovered pangolin from sting operations has led to rehabilitation sometimes as long as a year. Even after the pangolin has been medically treated for the inevitable dehydration and pneumonia acquired during its capture, it may take many months to stabilise it from the stress it has sustained. The sound of male voices ( poachers are usually male) is enough to make it curl into a ball which is why female volunteers are normally used at pangolin rehabilitation centres. The rehabilitation process is highly intensive as one cannot feed them in captivity but need to be accompanied on very long foraging walks . However these efforts are proving to be 85% successful. Sausage Tree Safari Camp supports these efforts via putting up free stay prizes at fundraising auctions, Back to the question, what fate for the pangolins? Something radical needs to happen if this extraordinary mammal avoids extinction within 10 to 15 years at the present rate of loss. It’s in a worse predicament than that of the other keratin carrying much poached African mammals, the rhino. The rhino can have its horn removed without harm to it and it regrows , no such option for the pangolin and its scales . The rhino can be kept in full and semi captivity and breeding farms . The pangolin cannot be kept in any kind of captivity. In an open letter to Director General of the World Health Organisation and the Executive Director of UN Environment program which can be found on the website below, Professor Jansen highlights the zoonotic origins of all the pandemics known to man including the current Covid - 19 virus which is thought to originate from a wet market in Wuhan whereby a natural host species, in this case the horseshoe bat, came into close contact with an intermediate species thought to be a pangolin via blood and/or excreta and was then consumed by a human. The proposal is not for a global ban on wet markets as this would be unrealistic and unfair to millions of people whose diet is wholly dependent on the animals and plants sold therein. Rather, to educate and regulate against the known SARS virus-carrying mammal species being sold in wet markets is the way forward to avoid further pandemics. The bycatch of this strategy, if adopted, could be the survival of the pangolin. If you want to help save the pangolin then please make a donation via: http://www.africanpangolin.org/
