African elephant populations have stabilized in their Southern African homes

African elephant populations have risen and fallen incredibly fast over the last few centuries. It is estimated that as much as 20 million Savanah elephants roamed Africa in the year 1800, but in 1979 just 600,000 remained, and in 2016 just 415,000 live in Africa. At that point, over 100,000 had been poached in the previous decade.

Unfortunately, it is not merely a case of making more parks. Elephants are incredibly intelligent, but so called fortress reserves, are not good enough. Indeed, less well protected reserves, that are linked together by migration corridors, are far better for the elephant population, than the aforementioned fortress reserves.

These corridors have multiple benefits, from allowing elephants to leave overpopulated areas, to being able to move to places where food and water are available. It also means that the elephants can leave areas of heavy poaching, for instance the Virunga national park, where elephants virtually disappeared in the 1990s, but have started to return from Queen Elizabeth national park in Uganda, across the border.

Where animals cannot move, one often has a boom and bust kind of population dynamic. Now, it should be noted, that this is not always easy, as migration corridors are rarely completely empty of humans, so there is more conflict in these areas, never-the-less, it is clear that these corridors are essential, if these elephant populations are to survive into the long-term. Of course, it also leads to an interesting situation, where virtually all of the huge ecosystems in Africa are along borders, as this allows more than one country to share the cost.

Of perhaps greater worry, this population of 415,000 is both the African savannah and African forest elephant. Yet these two are completely separate species, African forest elephants are nicknamed the gardeners of the forest, and it is questionable whether it can survive as effectively in the long-term without their recovery. The African forest elephant had a population of 26 million in 1800, it is unclear how many are left, but what is clear, is that their population has collapsed in the last few decades.

Restoring a DRC reserve from a ‘triangle of death’ back into a thriving wildlife reserve

Upemba national park had virtually all its large mammals poached, but it is coming back (below is a 3 minute video about this decline).

Just a couple of years ago, 16 members of the Bakata Katanga militia suprised a party of 4 rangers within the park (close to the Upemba base camp). Lying in the south-east of the DRC, this reserve once teamed with life. Tens of thousands of elephants, alongside lins zebra and many other species roamed free.

Palm oil deforestation continues in the Leuser ecosystem

The Leuser ecosystem is one of the most biodiverse in the world, and is the only place where tiger orangutans elephants and rhino can all be found in the same place (and this ignores various special species such as bears and gibbons among many others, which still call this ecosystem home).

This deforestation, carried out to create palm oil plantations, is even occurring within a national park – somewhere where the rules means that a plantation cannot be given a licence. 2 new palm oil processing mills have sprung up near the deforesting concessions: keeping these supplied may well, now be driving further deforestation. Below is a 219 second documentary on this fascinating ecosystem.

US has tightened African elephant trophy import rules but stops short of banning

Elephants hunting used to be a common activity. This was banned in Kenya in 1973 and in Botswana in 2014. The trade in Elephant parts was banned in 1989.

For many years, however, conservationists have called for rich countries to ban imports of hunting trophies on a country by country basis. This is for a simple reason – a reserve like the Kruger, has a real issue with a growing elephant population, yet at the same time Nigeria has only 400 elephants left. Tanzania has seen a reduction of elephants of 63%, while Mozambique has seen a reduction of 34%.

This new ruling suggests that imports are only allowed from populations which are large enough to support the loss. Now, I would be interested as to how this is worked out. For instance, could I buy a tiny parcel of land, on the edge of a large reserve, and allow any elephants that step on my land to be hunted?

  • Somewhere like the Selous game reserve, would in theory be acceptable for elephant hunting. If we go back to the 1976 there were approaching 109,000 elephants. However that population is now thought to be around 13,000 – hunting should be banned until the population has recovered. If a hunting reserve cannot afford to police well enough to eliminate poaching, it should not be allowed to hunt (the number of poached and hunted elephants must be below safety levels.
  • The Serengeti ecosystem also does not have a large elephant populatino so cannot allow hunting
  • The African forest elephant is considered critically endangered, so none of these elephants should be hunted

The smallest elephant in the world is in danger of being lost

There has been much discussion about the history of elephants in Borneo, and whether their loss is a problem

The origin of elephants in Borneo is unknown. Known for hosting the smallest elephants in the world, there are 2 theories as to how the elephants got to the island. The first is that they were released by a ruler in the 17th century (The most rapid population growth ever seen was 7,1% after the end of poaching in a reserve in Tanzania, a population of 30 elephants could become 1000 in just 50 years) – if this was the case, then their loss would not be bad; and the second is that actually the elephants arrived on the islands hundreds of thousands of years ago (as high as 300,000 years).

It is increasingly agreed that the second one of these ideas is likely to be correct. Though having said this, genetic analysis suggests that the whole population started with just 28 elephants.

Just 1000 are found on the island at the current time.

All wildlife on Borneo is at threat, as the palm oil industry continues to demand increasing quantities of prime rainforest be cut down. As this happens, elephants are forced into human areas, in their search for food, and then into conflict.

The Borneo elephant has only recently been assessed by the IUCN red list as a separate subspecies, but it is hoped that this recognition might increase tourism on this species as well as conservation dollars to save this species from its slow slide towards extincion

It is becoming increasingly clear: humans are responsible for the loss of mega fauna that we can see in the past

The skeleton above is the closest we can get to a real mammoth, as a result of their extinction. However, it is not the only missing large species – indeed, the elephant family alone, is thought to have around 30 extinct members. Aside from these, there are 2 known extinct species of the woolly rhino, cave lions and sabre-toothed tigers, and various species of bear, among many others.

If you go back 50,000 years, there were 57 species of megaherbivores (herbivores weighing over a ton), yet just 11 of these survive today – these include the elephant species, the rhino species the hippo and the giraffe.

The island where the feral species is an elephant

Around the world, there are invasive species – from grey squirrels in the UK, to Macaques on Gibraltar, however, all these pale on comparison to having to live with wild elephants.

The elephants were bought to the Andaman islands in the late 19th century, to work in the timber operation, which continued until the last few decades. Thankfully, much of the forest in the islands survives – with some islands retaining almost 90% forest cover. This means that the elephants might well be able to thrive into the future.

The islands lie 850 miles from the coast of India, which means that while elephants would not have existed natively on the islands, there are many species which would be found in the same area.

Interview Island and North Andaman hosts these elephants – though they need to be watched, as a population of 100 elephants is already small, but if split between 2 islands, humans may well have to be helped to remain genetically varied enough to survive long-term.

While some have suggested that the elephants have damaged biodiversity, with some species having become less common, this ignores the impact of the timber extraction – it is far more likely that this is an impact of the many decades of pulling specific trees out of the forest.

Given the endangered status of the Indian elephant, this population is precious, but whether it can be left where it is long-term is something we do not know. There are still roughly 30,000 elephants in India, but the Andaman island elephants are going to need to be watch, long-term, to make sure that they do not damage species only found in their new home.

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).

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.

Ratites

Ratites

You will find images of each of these species below, linking to a page about each, similar or closely related species will be grouped together initially, until links require their splitting. 

It should be noted that there are a few other species, which have been lost over time. These include 3 species of elephant bird from Madagascar and 9 species of Moa, all of which was found in New Zealand and all of which were lost. Thankfully at the current time, the Kiwi has not followed its bigger cousin, but we must not be laid back

Common ostrich (female)
Somali ostrich male
Kiwi species

Found across much of Africa, the common ostrich is a relatively common site in the right places. Capable of defending itself, it is usually only found in larger reserves. There are a number of subspecies click here to read more and visit our ostrich page

Recently shown to be a separate species (though looking very similar to the common ostrich), this is found in Somalia, most of Kenya, and north-east Ethiopia. Click here for the Ostrich page

Restricted to the islands of New Zealand, the kiwi is not one species but 5. Having arrived on these islands when there were no land predators, they lost the ability to fly. Unfortunately the arrival of Europeans quickly changed this. Click here for the Kiwi page

Rhea species
Cassowaries
Tinamou - a group of 46 species

The Rhea consists of two species, named the greater and lesser Rhea. They are found on the plains of eastern and southern South America. To visit their page, click here

Cassowaries are found in Australia, Indonesian islands, and the island of New Guinea. Perhaps not surprisingly, given their distribution over a large area, and the fact that they are flightless, so cannot mix, there are 3 species. To visit their page click here

Finally the Tinamous family, a group of 46 species. It is likely to be a while before I get round to building pages for all these species, but should you work in conservation or tourism with these species, you can help fill in the gaps. Although initially thought to be a sister clade, recent analysis has shown that these birds are part of the Ratite family –  Tinamou birds can fly

Those I have put in pictures for (29) are here  but we will hpe to add the rest over time, as well as building species pages
