On the founding of Kahuzi-Biega National Park, locals were pushed out -they now have the right to return, what will happen

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).

Medicinal use in wild great apes – a new study shows how many

News article on a recent study on chimpanzee medicine

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.

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.

Hippo locomotion underwater makes more sense. This is their element

Bushbuck

The Cape bushbuck , also  known as imbabala is a common, medium-sized and a widespread species of antelope in sub-Saharan Africa. It is found in a wide range of habitats, such as rain forests, montane forests, forest-savanna mosaic, savanna, bushveld, and woodland. Its stands around 90 cm at the shoulder and weigh from 45 to 80 kg. They are generally solitary, territorial browsers.

Although rarely seen, as it spends most of its time deep in the thick bush, there are around 1 million in Africa

Common Eland

 The common eland (southern eland or eland antelope) is a large-sized savannah and plains antelope from East and Southern Africa. An adult male is around 1.6 m  tall at the shoulder (females are 20 cm  shorter) and can weigh up to 942 kg with a typical range of 500–600 kg. Only the giant eland is (on average bigger). It was described by Peter Simon Pallas in 1766. Population of 136,000, can form herds of 500

Common Eland

Giant Eland

Giant Eland

The giant eland, (also known as Lord Derby’s eland and greater eland) is an open-forest and savanna antelope.

 It was described in 1847 by John Edward Gray. The giant eland is the largest species of antelope, with a body length ranging from 220–290 cm (87–114 in). There are two subspecies: T. d. derbianus and T. d. gigas.

The giant eland is a herbivore, living in small mixed gender herds consisting of 15–25 members. Giant elands have large home ranges. They can run at up to 70 km/h.  They mostly inhabit broad-leafed savannas and woodlands and are listed as vulnerable and have a wild population of 12,000-14,000

Greater Kudu

The greater kudu  is a large woodland antelope, you can see its distribution on the map. Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. 

The spiral horns are impressive, and grow at one curl every 3 years – they are fully grown at 7 and a half years with 2 and a half turns. Three subspecies have been agreed (one described has been rejected) :

 

  • T. s. strepsiceros – southern parts of the range from southern Kenya to Namibia, Botswana, and South Africa
  • T. s. chora – northeastern Africa from northern Kenya through Ethiopia to eastern Sudan, Somalia, and Eritrea
  • T. s. cottoni – Chad and western Sudan
They are listed as near threatened with 118,000 in the wild
Greater Kudu

Lesser Kudu

The lesser kudu  is a medium-sized bushland antelope found in East Africa.  It was first scientifically described by English zoologist Edward Blyth (1869).It stands around 90 cm at the shoulder and weigh from 45 to 80 kg. They are generally solitary, territorial browsers.

While currently rated not threatened, its population is decreasing. It currently stands at 100,000, but it is loosing territory to humans

Common Bongo (and mountain Bongo)

The bongo  is a large, mostly nocturnal, forest-dwelling antelope, native to sub-Saharan Africa. Bongos are characterised by a striking reddish-brown coat, black and white markings, white-yellow stripes, and long slightly spiralled horns. It is the only member of its family in which both sexes have horns. Bongos have a complex social interaction and are found in African dense forest mosaics. They are the third-largest antelope in the world.

The Common (western or lowland bongo), faces an ongoing population decline, and the IUCN considers it to be Near Threatened.

The mountain bongo (or eastern) of Kenya, has a coat even more vibrant than the common version. The mountain bongo is only found in the wild in a few mountain regions of central Kenya. This bongo is classified by the IUCN  as Critically Endangered (where it breeds readily). (this is not on the map above). Only 100 live wild, split between 4 areas of Kenya

Common Bongo

Nyala

The Nyala is a spiral horned species

 found in Southern Africa. The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C  and during the night in the rainy season. The nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. It is a very shy animal, and prefers water holes to the river bank. Not territorial, they are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. They have one calf after 7 months of gestation. Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

Mountain Nyala

 The mountain Nyala (also known as the Balbok) is a large antelope found in high altitude woodlands in just a small part of central Ethiopia. The coat is grey to brown, marked with two to five poorly defined white strips extending from the back to the underside, and a row of six to ten white spots. White markings are present on the face, throat and legs as well. Males have a short dark erect crest, about 10 cm (3.9 in) high, running along the middle of the back. Only males possess horns.

The mountain nyala are shy and elusive towards human beings. They form small temporary herds. Males are not territorial. Primarily a browser. They will grazing occasionally. Males and females are sexually mature at 2 years old.. Gestation lasts for eight to nine months, after which a single calf is born. The lifespan of a mountain nyala is around 15 to 20 years.

Found in mountain woodland -between 3000m and 4000m. Human settlement and large livestock population have forced the animal to occupy heath forests at an altitude of above 3,400 m (11,200 ft). Mountain nyala are endemic to the Ethiopian highlands east of the Rift Valley. As much as half of the population live within 200 square km (77 sq mi) area of Gaysay, in the northern part of the Bale Mountains National Park. The mountain nyala has been classified under the Endangered category of the  (IUCN). Their influence on Ethiopian culture is notable, with the mountain nyala being featured on the obverse of Ethiopian ten cents coins.

Situnga Antelope

Situnga

The sitatunga  (or marshbuck)is a swamp-dwelling medium-sized antelope found throughout central Africa (see the map to the right. The sitatunga is mostly confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps.

The scientific name of the sitatunga is Tragelaphus spekii. The species was first described by the English explorer John Hanning Speke in 1863.

It is listed as least concern with 170,000-200,000, and are found in 25 countries. However 40% live outside reserves, so the situation could get worse fast.

Note: these animals have been dealt with in less detail than others. Should you be interested in finding out if I have written on these animals or what exactly I said, you can find a list of articles about each below its information.

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!

Southern African hosts roughly 227,000 elephants out of 415,000 on the continent (in addition there is around 100,000 forest elephants).

In 2020, the estimate was that 30,000 elephants were being killed each year. While the majority of these were in the west african rainforest, and in east africa (it was estimated that the Selous lost 10s of thousands alone).

It is not even just in recent years, but over the last century, that the elephant population in southern Africa has fallen.

Another bonus, is that scientists are now finding clear proof in study after study, that elephants do better in reserves connected to other reserves, than they do in fortress reserves.

It is of course true, that a single reserve is better than nothing. However, increasingly, countries are recognizing that by building their reserves on the borders of their countries, their neighbours can also have reserves, and between them they can put aside enough land to truly allow elephants to live a more natural life.

From the Limpopo transfrontier park – a transfrontier reserve that includes the Kruger, to the Kalahari Zambezi transfrontier park, the Serengeti mara ecosystem and so many more, this is being shown over and over again.

Careful planning of reserves in west african rainforests, can expand this success at great speed if done carefully.

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.

Pangolins are returning to Kenya

Long thought to be extinct in the country, one was caught, back in 2018. As a result, effort is being put into protecting this species. Farmland around the Serengeti erected electric fences in order to stop elephants from stealing their crops, however, unfortunately, they have been having an unintended consequence.

Pangolins need to be able to roam large distances, and they have been regularly being electrocuted. Unfortunately, they roll up in a ball, as a natural reaction to threat, and this has lead to many rolling up around the wire, thereby being electrocuted.

This discovery in 2018 was of a dead pangolin, and as a result, many farmers have changed how their electric fence works to help protect this creature.

There are only thought to be 30-80 pangolins left in the country, but by making these small changes, the few pangolins that remain will be able to thrive, and the population is likely to grow.

This is a pangolin sighting that was filmed on the Massai mara
