One of the problems with cutting down rainforest, it often what is left is so fragmented that it is useless for conservation. Remaining blocks of forest must allow a viable population of the rarest creatures, in order for the animals not to need to travel outside protected areas.
In Borneo, like in Sumatra, there has been a rapid loss of rainforest over the last few decades. Often it is claimed that enough is left behind in order to conserve the animals that live there.
In Borneo, while there is still a large quantity of wilderness, this is increasingly fragmented.
Generally great apes are animals that live in community. Indeed, one of the reasons that great apes developed such large brains is as a result of their need in social situations. Great apes (along with lesser monkeys, dolphins, bears and wolves, with a few more) require a large brain to remember things about the many individuals that they socialize with, and how each has behaved, who is nice.
It is back in the 1940s that wolves were last resident in the Grand Canyon national park. This is why it was so exciting that a grey wolf is roaming the northern rim of the grand canyon.
2200 polar bears live on the west coast of Greenland. It is unknown how many live on the east coast, but this group appears to be living in a place where they were formerly thought incapable of surviving.
Should you wish to read it, I have included a link to it above.
These birds are beautiful, and for some time, have been an exciting moment when encountering them in Spain or eastern Europe. Unfortunately, their more regular visits to our shores is yet more signs of climate change.
The fact that they have returned to the same nest site may well suggest a group which intends to make this their annual nesting ground.
3 have been spotted, which include a nesting pair.
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.
