In most countries, if a dam was to cause so much destruction to the last habitat of a species, the dam would likely not get permission to be built.
It is true that the dam will only take about 20% of the land in question, directly. It will also split the population in half.
It is not surprising that the Norwegian sovereign fund has pulled out of this dam
Given that only around 800 Tapanuli Orangutans survive in the wild, the loss of just a handful is bad. A loss of 20% of the remaining population could quite rapidly push the population towards extinction, particularly as it will split the few remaining Orangutans into separate populations which cannot interbreed.
Norway has a huge sovereign fund, into which it pours the countries earnings from fossil fuel extraction. Perhaps recognizing that this has a shelf life which is not far from ending, Norway has made sure that for the most part its sovereign fund is good for the natural world (alongside giving good returns)
Generally rules on financing should have ruled this project out in the past, so it is good that this decision has been eventually made.
Will the dam still get built? We will have to wait and see.
Grey wolves from Oregon now appear to be thriving in California (where they disappeared from about 100 years ago).
Wolves and cubs in California
Wolves have never been reintroduced to California, instead they were returned to Yellowstone, re-entered Oregan back in 1999, and then entered California in 2008.
Short of a sudden sustained assault on their numbers, they are back in California and are likely to multiply over the next few decades to take back up their position as apex predators. This should not be feared in any way, with sensible management, it could end up benefiting California, with healthier ecosystems, less car crashes caused by wildlife amongst many other benefits.
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.
Could this provide a way for wildlife and humans to thrive in close proximity?
In Borneo, while there is still a large quantity of wilderness, this is increasingly fragmented.
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.
Borneo elephant – the most positive estimate, suggests that there are 1500 remaining in the rainforests of Borneo
Sumatran elephant 2400-2800
Sri Lankan elephant 7500
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.
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!
Chad being a west African country, has far fewer lions than in the east, read on for more
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.
A report has calculated that the reintroduction of 9 species would do so much benefit to the ecosystems that they are found in, that these reintroductions would help us to keep global warming to 1.5° C.
While some of these would require human adaption, many would have benefits far beyond climate change.
Have you ever seen a red panda in the zoo? While the wild population has halved from 5000 to 2500. Yet at the same time the number in zoos has increased.
Although far smaller, the red panda can be fascinating to watch. Recent analysis shows it is not just looks, these animals are surprisingly similar
Europe now has about 407 individual red pandas and while figures are harder to find elsewhere, there are probably more red pandas now in zoos which in comparison to the giant panda population in zoos is around 500 world wide. Why is this?
Estimates vary, but it is thought that 15-20 wolves are in the country. This is made up of 1 pack in Flanders, and another in Southern Wallonia as well as a newly settled pair (this pair is likely to become a pack if allowed to survive).
Wolves have returned to Belgium. While only numbering about 20, if allowed to, it is likely to grow
Across the border in France and Germany, numbers are far higher. As a result, should these wolves be left alone, the numbers are likely to grow and spread.
Experts can be very good at spotting signs and clues of their presence, these skills are important to track the wolves however, these skills can also become very useful in ecotourism.
