Kahuzi-Biega National Park was established in 1937 by the Belgium colonial rulers and then expanded in 1975. It now covers 6000 square km or 2300 square miles. Roughly 13000 Batwa were cleared out of the area to make way for the park (along with other people who had settled more recently).

It would appear that chimpanzee medicine is quite a complicated field.
- Christella parasitica: A fern with anti-inflammatory properties that one chimp ate to reduce pain and swelling in an injured hand
- Scutia myrtina: A cat-thorn tree whose bark was consumed by a chimp with a parasitic infection
- Khaya anthotheca: An East African mahogany tree whose bark and resin have anti-inflammatory effects
- Antiaris toxicaria: A plant with leaves that have anti-tumour properties
- Cordia abyssinica: A plant with pith that has anti-malarial and anti-bacterial properties
- Ficus capensis: A plant with anti-bacterial properties
- Ficus natalensis: A plant with bark that has anti-diarrheal properties
- Ficus urceolaris: A plant with leaves that act as a de-worming agent
- Vernonia amygdalina: An African relative of the daisy whose pith is consumed to get rid of intestinal worms
- They have been known to apply insects to injuries – the insects may have anti-inflammatory or antiseptic properties that help heal wounds. Chimpanzees also have quite a range of cultural behaviours, so there are some of their behaviours with little notable purpose behind them (though it is possible that some or all of these may prove to have a purpose that we as observers have not yet discovered)
This is a significant range of conditions that can be treated, though it should also be noted, that this knowledge is likely to be shared in the group, as no one individual will have seen their mother suffer from all these conditions.
While gorilla medicine does not appear to be quite as advanced, it does include
- Fromager tree (Ceiba pentandra) – The bark of this tree contains chemicals that are effective against multidrug-resistant strains of E. coli.
- Giant yellow mulberry (Myrianthus arboreus) – The bark of this tree contains chemicals that are effective against multidrug-resistant strains of E. coli.
- African teak (Milicia excelsa) – The bark of this tree contains chemicals that are effective against multidrug-resistant strains of E. coli.
- Fig trees (Ficus) – The bark of these trees contains chemicals that are effective against multidrug-resistant strains of E. coli.
Orangutans have also been observed –
- Rakus the Sumatran orangutan – In June 2022, researchers observed Rakus treating a wound on his cheek with a poultice made from the leaves of the Akar Kuning plant. Rakus chewed the leaves, applied the juice to the wound, and repeated the process several times. The wound was fully closed within eight days. This was the first time scientists observed a wild animal using a medicinal plant to treat an injury.
- Bornean orangutans have been observed eating plants with known medicinal properties, including ginger leaves and stem, and plants used by traditional healers to treat internal illness, tumors, and hemorrhage.
- Orangutans also use plant extracts to treat pain.
- Dracaena cantleyi – A study found that orangutans use the bioactive properties of Dracaena cantleyi for self-medication.
And finally, Bonobo –
- Manniophyton fulvum – Bonobos have been observed swallowing the leaves and stem strips of this plant, which has medicinal properties.
- Leaf-swallowing – Bonobos may swallow leaves as a form of self-medication. One hypothesis is that the leaves act as a time-release capsule, with medicinal and scouring effects.
- Overlapping plant use – Bonobos’ food repertoire overlaps with many plant species used by local populations to treat disease.
It perhaps should not be a surprise that other great apes have the ability to treat simple ailments – after all, there are a wide range of illnesses, for which a sensible treatment is very simple. One of the most common simple long known treatments in humans in dock leaves – when rubbed on a stinging nettle sting, it greatly reduces both the pain and irritancy of the of the sting. It is not even restricted to the great apes with birds, bees, lizards, and elephants all regularly treating simple conditions. Even a domestic dog knows to eat grass when feeling sick.
Amazon rainforest droughts linked to climate change
Before and after (after being above) image of a river in the Amazon rainforest
Why is this a problem? Well there are several issues that should concern everyone. The natural end of the line, is for the complete loss of the Amazon rainforest. There is much fear that it may be another tipping point, and that therefore, once the rainforest starts failing, it would accelerate the loss of the rest.
Continue reading “Amazon rainforest droughts linked to climate change”Hippos can fly! (well at least leave the ground)
To be honest, I find this an odd piece of news. In the 1870s, the horse was photographed with all 4 feet off the ground at the same time. In fact, horses do not only do this at the gallop, but also at the trot.
If this is true, why should the hippopotamus be any different?
It is true, that a horse can run faster, reaching speeds of 71km/h, but even at the trot they reach speeds of 48km/h. However, a trotting horse can be as slow as 13.1km/h. Well how does this compare to a hippo?
Hippo can hit a speed of 30km/h, more than twice the minimum speed of a trotting horse, so the surprise seems odd.
There is perhaps one solution for this late analysis. Very often, when a hippo is encountered by a human and is running, it is moving towards the human, and therefore getting to safety is far more important. Hippo are not slow animals; it is true that they look ungainly, but this is because they are essentially designed for under water. Below is footage of a common hippopotamus, moving along under the water. Here, in their own element, you can see a hippo bounding along the bottom of the water, leaping effortless along.

Birds of prey populations across Africa are collapsing
Why are these birds having population collapse?
- Martial eagle
- Bateleur eagle
- Dark chanting goshawk
are all disappearing rapidly. Indeed, a study of 42 species, 90% had seen significant declines, with more than 2/3 (that is 28 species) showing evidence of becoming extinct.

The problem is that, this is not merely a case of the large raptors disappearing, and no longer being able to follow the circling vultures to find a kill. Instead, it has very serious consequences for human populations. The decline of the Indian vultures lead to a rise in rabies in the local human population in the early 1990s.
The African birds are very large, with some having the capability of hunting prey as large as jackals and antelopes. Encouragingly, this decline has been far less noticeable within reserves, and should we meet our target of setting aside 30% of land for conservation, it would allow more to thrive.
This has been worse in west Africa, where there are not enough protected areas, and those that exist do not have enough funding. In India, the lack of vultures has lead to an increase in the feral dog population, which has lead to an increase in rabies as these dogs bite humans that they interact with
African elephant populations in southern Africa have stabilized!
Platinum Rhino, the worlds largest captive rhino breeding operation sold to africaparksnetwork! (update, instagram embed did not work)
Hearing this news, one might think “great, another 10-20 rhino”? Think again.
Platinum rhino holds as much as 15% of the current wild population in its operation -2000 individuals. Here is an instagram on the news!
This could be great! Current rhino numbers are estimated to be in the low 2000, down 79% since 2011. Releasing the whole herd back into the Kruger could allow numbers a sizable boost, and rapidly move the kruger back towards its former stronghold of the white rhino. However, in the first half of 2023 over 200 rhino were poached from the Kruger, suggesting that this is not going to be easy.
Unfortunately, the Kruger is already one of the best preserved large reserves in the world. Thankfully, rhino horn has dropped in value from its peak in 2012 of $65,000 per kg, down to a current $8000 per kg. It would be good to depress this further, however the risks for the poacher are very high: not only are many poachers killed by the rhino, they are also often killed by other wildlife such as lions – and the Kruger has a sizable number of man-eating specialists.
I suspect the organization will spread the rhino around, across many of their reserves. Hopefully the recognition that farms like this make no sense, will allow them to thrive back in the wild.
Education is still needed in China, Vietnam and elsewhere. Rhino horn is the same substance as your finger-nails, Keratin. Consuming it will make no difference to any medical condition, science has tried to show any positive health benefit, and can see nothing scientific – at best a placebo effect.
Below, is a video about this farm, 6 years ago back in its heyday. Hopefully, all these rhino can recover white rhino populations far and wide.
Could bonobos go extinct because of malaria?
Humans are not the only species of primate which can get ill or die as a result of malaria – an illness carried by mosquitos. The problem is, that while humans have developed ways to fight the infection, and many humans live far from where they could get bitten, the Chimpanzees gorillas orangutans and Bonobos all live in hot humid rainforests which are perfect breeding places.
Bonobos live the other side of the Congo river to chimpanzees, and while a relatively recent species to appear, they are very different to chimpanzees – make love not war, the hippy priimate.
This becomes a greater problem when humans have already reduced these species populations so dramatically.
One bonobo population was found to have developed an immunity to the illness, but unfortunately this has not been discovered anywhere else.
Should bonobos have got this condition naturally, it would have been fine – while it may have killed a small percentage, overall they would have been fine. Unfortunately, we have pushed them so close to extinction, that in many areas they cannot afford these extra deaths from malaria.
Up until recently, while infection had been noted in other great ape species, bonobos had not been found to suffer from the condition, but now we know better.
The issue is that, with humans having reduced populations through direct hunting and deforestation, the loss of any individual can have a far greater impact on the local population.
More people going to see this species in the wild would help save them, as it will give them value to the local population. We hope to add links that you can use to arrange your wild travel as soon as possible.
