I wonder what proportion of the country would recognize the name Chris Packham? He has been one of the lead presenters for the BBCs natural history unit for decades. Why is people like this important? Without people like this, all sorts of threats to our world, including things like climate change would be less well known in the public.

These people are essential for disseminating information which might allow us to deal with these challenges without leaving a dystopian world to our children. Naturalists are important, as they give us the knowledge to deal with many problems far cheaper than any manmade solution.
Oil, is increasingly recognized as an asset that is likely to be worth very little in the future. Does this mean it has no value now? no of course not. Still, it is likely to move in that direction soon.
It is, unfortunately, a fact, that meat eaters create a significant extra quantity of carbon released into the air. How much? Well this varies from place to place, and product to product.
While many think that grass fed beef is good for the environment, the methane emissions swing this badly
There are an increasingly large number of people who are recognizing this issue. Now while some will argue that without the meat industry, much of the UK farmland would be built on, and that this would be disastrous for the environment are missing the point. We live on an island, and as such it is in our own best interests to make sure that the worlds ice sheets do not melt.
Should you wish to read it, I have included a link to it above.
This years bee-eaters in a short video
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 have been many suggestions that the scientific consensus has not been reached, when it comes to climate change, either to its existence or humans effect on it,
Hi all, we are trying to set up a new mapping program for you to see all the sites that we list (and hopefully show many thousands that will be added over the next few decades)
The website continues to grow, we hope eventually to have other writers, but for now thats in the future
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.

How many of you knew about a pangolin? How many of you knew about a pangolin before say 5 years ago when their poaching became big news.
Generally the reason that they are little known about, is that they are secretive, and one of the most strictly nocturnal animals in the bush.
Despite this, seizures of tonnes of pangolin scales are regularly made on the way to Vietnam or China (and other similar parts of Asia). To be clear, in pretty much all of these countries the authorities are making lots of effort to stamp out this trade.
So this is why it is so horrifying to hear that poaching is not the primary human cause of death.
Electric fences!
Now it should be noted, that there is a wide range of predators in the African bush. We all know about lions and leopards, and even cheetah.
What about the smaller species?
The caracal, and serval are both cats that are incredible jumpers, and as such usual fences will not cause them a problem as they can jump over. Black backed jackals? Well these canines, are essentially the equivalent of the northern hemispheres red fox. Certainly, it is true that these animals might be a threat, but they are too savvy to be blocked by a fence, and anyway, live happily both sides of the fence as it is.
Electric fences are used in South Africa far more than other countries in Southern Africa: South Africa has about 6,000,000km of fencing, while Botswana has 3000km and Namibia 1100km.
So what can be done?
Well Pangolins are not a tall animal, but tend to travel on their hind legs. Raising the lowest strand of this fence from 20cm to 30cm would likely eliminate these deaths.
Why are they specifically at risk? Very sadly, by walking on their hind legs they expose their belly, when on the move. They struggle to see the strands of the wire, so the first thing that they know is it touches their sensitive underside. What is worse, Pangolins roll up into a ball when scared, but in this case this does not help, as this will leave the pangolin hanging from the wire. As the shocks keep coming the pangolin stays, and often starves or dies of thirst.
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.
