There has been a steady 1 or 2 sightings of humpback whales off the coast of Cornwall over the last 5 or so years – with Cornwall wildlife trust identifying 10 individuals. However the others have visited in the winter, so this might be an indication of a recovering population.
This one was encountered about 2 miles from shore, so would only be seen from a boat.
Unfortunately, there is still a great deal of recovery that this whale population has to do. At their lowest it is thought that there were only 700 in the North Atlantic, but that number is now 35,000. You might think that this is a fantastic recovery, but best estimates suggest that there were around 200,000 humpback whales in the 16th century, before whaling began, so the population could still grow to be 500% of its current size and still not have reached the number of individuals that once existed.
Still, it just makes it clear, whether on the land or at sea, keep your eyes peeled, many species are recovering, and you never know what you might spot.
The African savannah elephant has declined by 60% over the last 50 years, and the African forest elephant has declined by 86% over the last 31 years.
So how close are these species to disappearing? There are currently 415,000african elephants in the wild, spread across 23 countries.
Unfortunately, their situation is highly different on different parts of the continent. Botswana still supports 130,000 Savanah elephants, while Tanzania lost 60% of their elephants between 2009 and 2014 (though some reserves till have healthy populations), one place hit particularly hard was the Selous which 40 years ago had over 150,000 and currently hosts 15,000 elephants.
While the African forest elephant was only recognized as a separate species in 2021 (there has been much argument about its status), what is not in question is its horrific decline in numbers. Indeed finding a web page that gives you an accurate figure is hard work, This may well because one does not exist. There has been horrific population declines over recent years, and the density is incredibly varied across its range.
Unfortunately one thing is clear, in areas of the Congo rainforest where elephants have lost, the forest does less well. There are many plant species which rely on elephants to carry their seeds from from where they are dropped. As such, without forest elephants we are likely to loose many species of trees – to the extent that it might threaten the survival of the Congo rainforest itself.
So how are Asiatic elephants doing? Unfortunately not great. There are 5 subspecies
First, the Indian elephant. This is the best known and most wide spread. Currently their Indian population is thought to be between 27,000 and 31,000, with between 10,000 and 14,000 across another 10 countries. While I am listing 4 subspecies these all look relatively similar.
Borneoelephant – the most positive estimate, suggests that there are 1500 remaining in the rainforests of Borneo
Syrian elephant – this species was lost as much as 1000 years ago, and occupied the western most part of the Asiatic elephant range.
As such what is clear, is that while African elephant populations are falling fast there is time to check this decline. The Asiatic elephant populations are far more in danger.
In the UK, it has been shown that at every solar farm looked at, there were more species, from insects such as butterflies, to mammals such as hares do well.
I would argue that these areas are not as good as reserves, but it is still a positive benefit. Indeed, it is conceivable that if wolves and bears returned to the UK, these sites could be fantastic for these animals.
In 2020, Trump gave responsibility for managing wildlife populations back to the states. Now one might argue that this is the right thing to do, after all it is democracy, but is it?
Many of the states in the USA are horrifically gerrymandered, with some having a small minority overruling the great majority. There are many intentional ways that this is done (republicans have been very good at it over time – there are been 2 times in recent years where democrats got more votes but lost.
The Christian Social Democrats believe that there is no place for wolves in Germany, and members of the party have called for their intentional extinction. Taking around 10% of the vote they are a small but relatively influential party – and given the way that elections work in Germany, coalitions are common. Unfortunately, coalitions will often give small parties an outsized voice, so this foolish position has the potential to become government policy faster than one would expect.
The Gir forest was the last refuge of the Asiatic lion. Back in 1893 it was thought that there were only 18 animals remaining. Thankfully that number has rebounded very well (there are scientists who doubt this extremely low number) and the Indian lion population is now thought to number about 600. The problem is, that the reserve is not particularly large at 1410 square km (544 square miles). Even in the Serengeti (which has one of the highest density of lions) there is about 1 lion for every 2 square miles, yet the Gir forest has more than one per square mile. This contributes to a mortality rate that is dangerously high, with 283 lions dying in the last couple of years.
As such it is not surprising that many of the lions live outside the reserve, and is thought that around 1 in 4 live outside the reserve.
This was one of the reasons that efforts were made to move some of these lions to other reserves, but Gujarat has blocked this despite loosing various court cases.
Now, it is not easy to live alongside lions, and the state government is both endangering the long term survival of the Indian Asiatic lion, as well as many of its human population by its determination to hold onto the whole population within its borders.
It is just 5 years since the Tapanuli orangutan was described. Despite this Orangutan being restricted to an area of Northern Sumatra, it is more closely related to the Bornean Orangutan than the Sumatran one. This might be the clearest indication of how long this species has been separate from its cousins.
The Tapanuli Orangutan split from its Bornean cousins around 670,000 years ago, while chimpanzee and Bonobo were split 1.5-2.2 million years ago. Baffling, the Sumatran Orangutan split from both the Borneon and Tapanuli Orangutan 3.38 million years ago. For context, Humans split from our chimpanzee ancestors 4-6 million years ago (so not much longer) and gorillas split from their chimpanzee ancestors 7-9 million years ago.
All this is to say, that while the Tapanuli Orangutan is relatively closely related to the Bornean Orangutan, it cannot interact with it as it is on another island; and the Sumatran Orangutan is too far removed to be able to interbreed.
It is thought that the Tapanuli Orangutan has faced population decline of 83% in the last few decades (three generations). Further threats are numerous. One of its biggest threats is a hydroelectric dam, which would remove much of the remaining habitat, but a gold mine, loss of habitat and an expansion of croplands are other threats.
Unfortunately little to nothing has improved in the last 6 years, they are probably closer to extinction now than ever. If you have followed this blog over the last 5 years, you will have seen that I have written on this new orangutan species a few times. We will continue to follow this animal on this blog – we must work to raise its profile and not merely chronicle its slide towards extinction.
Before humans started cutting down the forests of the UK, the pine marten was likely one of the most common carnivores in the UK. This voracious arboreal hunter is the reason that our resident squirrel is so acrobatic – these skills would likely be tested every day.
Indeed, pine martens are less widely spread in the USA which is likely one of the reasons that grey squirrels are so incapable of surviving alongside pine martens. Thus, in the UK we have this perverse situation within the UK, where the only refuge of the red squirrel (apart from small islands which can be cleared more easily) are areas of the country where pine martens also survive on.
In the UK, it has been long known that pine martens survive in Scotland. Protection of their forests must improve if we are to hold onto them for longer.
The wildlife of Indonesia now often looks like relatively unique to those islands. This is not the natural state of affairs. 60,000 years ago, a cousin of the orangutan lived on the mainland. Unfortunately, what appears clear, is that humans were responsible for the extinction of these animals as with so many more.
There are 2 species of Indonesian Rhino, the Javan rhino and the Sumatran rhino. Now it should be noted that these names are not an indication of a small range (or if it is, it is wrong) in reality, both rhino species were far more widely spread. Indeed mainland specimens lived within the 21st century.
A lioness has been spotted in a reserve in Chad, which has not recorded one since 2004!
Lions have not been spotted in the Chad national park of Sena Ouro since 2004, it is not clear if a few lions hung on for the last few decades or if lions have migrated over from a park the other side of the border in Cameroon, where the lion population is a little more healthy.
