Endangered species of Russian wildlife

Wildlife in danger in Russia

Although Russia is such a massive country with so many forms of natural habitat and countless types of flora and fauna, it is also home to the last surviving populations of many endangered species of wildlife. Hunting, habitat loss, pollution, pesticides and Climate Change have taken their toll just like in so many parts of the world today.  But let us look at some of the incredible creatures found in Russia whose very survival is threatened.

Siberian Tiger

The Siberian Tiger or Amur Tiger (Panthera tigris altaica), lives as its names suggest in Siberia and specifically in the Amur region.  It is the largest type of big cat in the world. In the 1940s it was threatened with extinction but due to conservation efforts the species has made a recovery, although numbers are still very low and an estimated number of 562 Siberian Tigers is all that are left. The Siberian Tiger's Conservation Status is "Endangered".

Oriental Stork

The Oriental Stork (Cyconia boyciana) is a truly beautiful bird that is now an endangered species with only about 400 pairs left. It used to live in China, Japan and Korea, as well as Russia, but it is believed to be extinct in Korea and Japan.

The Oriental Stork's decline has been attributed to hunting and habitat loss and the species is listed in the IUCN Red List of Threatened Species as "Endangered".

The Russian Desman

The Russian Desman (Desmana moschata) is really a type of semiaquatic mole. It is one of the two surviving species of desman, with the Pyrenean Desman (Galemys pyrenaicus) being the other. Although nowhere near as badly in decline in numbers as the Siberian Tiger and Oriental Stork, the Russian Desman has a "Vulnerable" Conservation Status and is down from 70.000 in the 1970s to just 35,000 in 2004.  This species was once hunted for its fur but nowadays pollution, loss of habitat and invasive species, such as the Muskrat, are threats to its survival.

It is found along the banks of ponds and streams in the Volga, Don and Ural River basins. It lives in small groups and burrows in the banks of where it is living. The Russian Desman feeds on fish, amphibians, insects and crayfish.


Saiga Antelope

The Saiga Antelope (Saiga tartarica) is an antelope species that is listed today as "Critically Endangered."  It once formed massive herds and lived in a vast area of the Eurasian steppes. It is now only found in one part of Russia and three areas in Kazakhstan.  It is extinct in China and southwestern Mongolia. 

This antelope was hunted in very large numbers and its horn is popular in Chinese traditional medicine. It has been used as a substitute for rhinoceros horn. Hunting of rhinos and Saigas for the superstitious belief  that the horns of these animals have miraculous powers has caused a terrible decline in numbers of these mammals.


Why did the Saigas die? 


The Saiga is also prone to unexplained die-offs when large numbers of the animals drop dead. Many Saigas died like this in die-offs every year between 2010 and 2014. It is bad enough that humans have taken such a terrible toll on this species without mysterious mortalities killing them like this too.

The once Common Eel is now Critically Endangered

The European Eel is no longer common

The European Eel (Anguilla anguilla)  used to be known as the Common Eel, and when I was a boy this was an apt name, however, this is no longer the case because this species of eel is now listed as Critically Endangered. In 2010, Greenpeace International added this fish to its red list. 


European Eel (Photo: Public Domain)


European Eels have a most unusual lifecycle. The adults spawn in the Sargasso Sea and the baby eels travel across the oceans to return to fresh waters far far away. How they navigate is not understood. They drift as larval eels for around 300 days before transforming into a stage known as "glass eels," which occurs when they approach the coasts.  Eventually they enter estuaries in the UK and Europe and transform again into elvers in the fresh water. The eels travel upstream and will also travel overland in storms. They live in rivers, streams, lakes, and ponds where they grow much larger and are known as "yellow eels," but after between five and twenty years or more they become adults that must return to the sea. The final stage is known as the "silver eel," and these eels swim all the way back to the Sargasso Sea where they breed and then die.



When I was younger the European Eel used to be one of the most easily found freshwater fish. You just had to go to any river or stream and turn over a few stones and you would be likely to see young eels or elvers.  In Cardiff, where I lived, there is a weir in Llandaff, and every year countless thousands of elvers used to try and ascend it. To do this they would leave the water at the edge of the weir and slither up the mossy wet rocks and wall.  If you put a bucket or net underneath and disturbed the mass of young eels at the top you would quickly get a net or bucket full of them. That was how easy they were to catch. Nearly every rock in the river would have elvers hiding underneath it or larger eels.  That was then but it is a very different story today, so what has happened? 

One of many endangered species

Like so many once common species, the European Eel is now rarely seen in Britain today and its numbers have dropped very dramatically.  Since the 1970s, it has been estimated that eels reaching Europe have declined in numbers by over 90%, possibly as much as 98%. This is surely a warning sign that all is not at all well, when it comes to the natural world and the flora and fauna of the UK.

So what has gone so wrong and where have all the eels gone?  The reasons are many and include: overfishing, hydroelectric dams and barrages blocking the way for the eels to ascend and descend rivers,  parasites, pollution and changes in the currents in the oceans. Whatever the cause may be, the eels have gone, and with them has gone the food source for many species of water birds, including Kingfishers, predatory fish, like the Pike, and even some mammals too, such as the Otter.  The eel is an important part of a food-chain, and without it other species are sure to suffer.  

Saving the European Eel


Fortunately all hope is not yet lost for the future survival of the European Eel. Fish passes are being increasingly installed in rivers with weirs and dams, so that eels and other fish, such as salmon, are able to get upstream.  

The number of eels is being monitored and there are projects in operation to save the European Eel. Restocking inland waters with young eels is one method that is being put into practise. 

The Guardian has reported that conservationists have suggested that the decline in numbers of the species has been halted and possibly reversed.  I hope this is true but it is far too early to know for sure!

Christmas Butterflies

Red Admiral

The Red Admiral (Vanessa atalanta) is often the last butterfly to be seen flying in the UK and parts of northern Europe. This colourful insect can be seen in December in mild winters and Butterfly Conservation reported on their Facebook page that the organisation had received recent reports of butterflies being sighted and they shared a photo of a Red Admiral.

The Red Admiral has Christmas colours too because its wings are boldly market with red and white on dark brown and black. This pretty butterfly, which is also found in Asia and North America, is a migrant to the UK but it can hibernate so is a resident butterfly as well. It is one of the last species to be seen in the late autumn, and can be seen feeding on ivy blossom and on windfall fruit. It also flies on sunny and mild winter days.

The Red Admiral's caterpillars feed on Stinging Nettle (Urtica dioica). 

Painted Lady

The Painted Lady (Vanessa cardui) is not a butterfly you will see in the UK at Christmas, but here in Portugal it is still about in December and I saw one the other day in a sunny spell in what was otherwise a cold and foggy day. It was a very pleasant surprise and got me thinking about this butterfly that is a very successful species unlike so many butterflies that are rapidly declining in numbers.

The Painted Lady is another migrant to the UK and Northern Europe.  It comes from North Africa and the Canary Islands but its northerly migrations have taken it as far as Iceland where it is the only butterfly species that has been reported. The Painted Lady has been found in most parts of the world and is almost global in its distribution.

Unfortunately, unlike the Red Admiral, the Painted Lady is unable to survive British winters in any stage of its lifecycle.  It is a truly remarkable butterfly though because scientists have discovered that it uses the jet stream to carry it on its migrations. The Painted Lady leaves Britain in the autumn to fly south and it does this by being carried in the fast-moving air of the jet stream.  

Besides the Painted Lady's extraordinary migrations, the species does so well because its caterpillar will feed on a lot of different food-plants, including species of thistle (Carduus). Sunflower (Helianthus),  Mallow (Malva) and Burdock (Arctium). Like the larvae of the Red Admiral, the caterpillars of the Painted Lady will also eat nettles. Caterpillars of the Painted Lady are often sold by butterfly supply companies such as Worldwide Butterflies.  They are ideal for schools where children can study the insects and watch them transform from caterpillars into chrysalises into adult butterflies. 

Butterfly World Project

Many butterflies are in danger of becoming extinct in the modern world due to habitat loss, pesticides, herbicides, disease and Climate Change, so they need all the help we can give them. Butterfly World Project in St Albans was set up to help butterfly conservation but has been forced to announce its closure.  Please help by signing the petitions to stop this happening.  I have written all about it in a previous blog here

Where does all the plastic go?


Plastic trash (Photo: Public Domain)

Where does all the plastic go? 
Into the sea, into the sea.
How does it get there, who threw it away?
Was it you or was it me?


Oceanic Gyres of Trash (Photo: Public Domain)


Plastic houseplants, why not real plants?
I saw the fake ones at the store,
Shoppers must want them, people must buy them;
I don't want to see any more.



It's not just hunting that'll kill the last whale,
Plastic will do it and it's a very sad tale.
What about the albatrosses?
They are dying out too,
They keep on fishing in the ocean's plastic stew.
These birds mate for life, only to watch their babies die,
From the plastic trash they feed them,
But they cannot understand why.

The plastic bag I bought, it very quickly broke,
If it ever gets burned there'll be poisonous smoke.

Plastic kills the turtles,
Plastic's eaten by the fish,
It is in the food chain,
And in the dinner on your dish.

Into the sea, into the sea.
How does it get there, who threw it away?
Was it you or was it me?

Paris’s Shortcomings: We Need Conservation, Not Conversation says David de Rothschild


Deforestation (Photo: Public Domain)


An excellent article entitled Paris’s Shortcomings: We Need Conservation, Not Conversation by author and explorer David de Rothschild, has been published by National Geographic, in which he talks about the serious shortcomings of the recent Paris conference on Climate Change. He points out the truly alarming rate at which our forests are being destroyed and species of plant and animal are becoming extinct daily. Nowhere near enough is being done to halt the ongoing destruction and nowhere near enough binding agreements have been made. It has been a lot more talk but not a lot of action!

David says: "...most experts agree that we are losing upwards of 80,000 acres of tropical rain forest every day. Factor in a statistic that says conservatively we’re loosing anywhere between 135-200 plant, animal, and insect species every day, and you realize that between now and 2020, we stand to lose 1,460,000,000 acres of tropical forest and 273,750 species!"

I hear what he is saying loud and clear!  It really saddens me to know how many species we are losing all the time.  You do not have to know much about nature to see that once common birds and butterflies are vanishing, as are honeybees, which we are told is due to Colony Collapse Disorder.

In the UK, most butterfly species are in rapid decline, as are formerly common birds like the House Sparrow.

Every time I talk to my elderly father, who lives in Cardiff, he complains about how he no longer sees birds like blackbirds, starlings, great tits, robins, green finches, wrens and hedge sparrows, all of which used to be regular visitors to his back garden.  When I have visited him I have seen for myself that these birds have gone.  So too have the swifts. These birds used to nest on houses in the street my father lives in. In May you would hear and see them all the way along the road but no longer is this the case.

I have recently blogged about the shocking decline in hedgehogs in the UK. They are now down to less than one million.  These animals used to be a common sight in our gardens at night.

So I know what David de Rothschild is talking about is true. We are losing species daily and we cannot bring them back.  Extinction cannot be undone.  Extinct means gone for good!

I thoroughly recommend De Rothschild's book The Live Earth Global Warming Survival Handbook: 77 Essential Skills to Stop Climate Change, and his Plastiki Across the Pacific on Plastic: An Adventure to Save Our Oceans.  This second book is about the voyage De Rothschild made across the ocean. He saw for himself that the fishes and marine life have vanished. Pollution by plastic and overfishing are destroying marine life daily and little is being done to stop this.  Too little too late is being done to stop the environmental destruction happening worldwide!

Petition to Save Butterfly World Project in St Albans

Butterfly World to close

I couldn't believe it when I read the news that Butterfly World was to close permanently. The Butterfly World Project in Chiswell Green, St Albans has reluctantly announced that they will not be reopening next year.  As usual it appears that money is at the root of the problem.  Butterfly World has been failing to make the profit it needs.

Phase IV of the Butterfly World Project was going to be the construction of a 100-metre-wide rainforest bio dome. It was intended to house hundreds of tropical butterflies, hummingbirds, insects, spiders and tropical plants. Sadly it has not attracted the funding it needs to go ahead, and John Breheny, who is the chairman of the engineering project for the centre, has put the blame on a "succession of trading losses."

Clive Farrell

Butterfly World was founded by lepidopterist and author Clive Farrell in 2009, and has attracted over 500, 000 visitors. 



 Farrell, by the way, co-authored The Butterfly Gardener with the late Miriam Rothschild.  I personally recommend this book, which looks in detail at how butterflies can be attracted to our gardens throughout the year, and what the insects really need to thrive. The Butterfly Gardener is an excellent book to get if you want to find out how we can help butterfly conservation.

Celebrity Support for Butterfly World

As well as attracting thousands of visitors and the support of countless members of the public, Butterfly World has been supported by a number of well-known celebrities, including Sir David Attenborough, Professor David Bellamy. broadcaster Alan Titchmarsh and actress Emilia Fox. 


David Bellamy talks about Butterfly World

Petition to Save Butterfly World from closure

With butterflies disappearing in the UK and throughout the world in alarming numbers, we need more places like Butterfly World not less. Many people still think that we can turn things around and save Butterfly World, and so a petition has been launched.

British hedgehog numbers in serious decline

The British Hedgehog is no longer common

Hedgehogs were once a very common animal in the UK, and in the 1950s there were an estimated 36 million living in our gardens, parks and countryside.  Very sadly this is no longer the case and The People's Trust for Endangered Species now believes there are fewer than one million left.  The alarming decline in hedgehog numbers has been reported on in The Guardian and by the British Hedgehog Preservation Society.

Threats to the hedgehog

Like so many endangered species of wildlife the hedgehog has many threats to its continued survival. Pesticides, such as slug bait,  can potentially harm hedgehogs that inadvertently eat poisoned slugs and snails. Even if the slug killer doesn't kill a hedgehog directly, the slugs and snails it does kill could have been food for the spiny animal. Habitat loss and degradation is another problem hedgehogs face. Many gardens are now paved over or kept so tidy that the number of insects and other invertebrates that hedgehogs feed on are drastically reduced in numbers. Hibernating hedgehogs can get burned to death if they are sleeping under a large pile of branches, twigs, leaves and other rubbish that someone has accumulated as a bonfire. 

Flooding caused by Climate Change is another threat to sleeping hedgehogs. Although the animals can swim to safety they are unlikely to be able to do so if water floods where they are resting or hibernating. The hedgehogs would be drowned in their sleep.

Hedgehogs are a very adaptable species that can live in a very great range of habitats and eat a wide variety of foods, including slugs, snails, worms, insects, centipedes, frogs, mice and snakes even. They can climb and swim. They wear a spiny suit-of-armour as a means of defence. They were once very common and widely distributed in the UK, however, like so many forms of British wildlife they have been unable to adapt fast enough to survive the sweeping changes humans have brought to the countryside.

Roadkill

Hedgehogs are one of the main animals that become victims of roadkill. Hedgehogs are mainly nocturnal creatures and this means that drivers have less chance of seeing them in the road ahead, and in any case, the animals are very bad at getting out of the way, even if they do sense danger. 

The number of hedgehogs reported as roadkill has fallen drastically too, which suggests that their populations have seriously dwindled in numbers. The animals are not there to run the risk of being killed crossing a road to begin with!

Hedgehogs in popular culture

Hedgehogs have been featured in popular culture in Britain in literature, poetry and song. Beatrix Potter's Mrs Tiggy-Winkle is a character so many children have loved.  Folk-rock icons The Incredible String Band wrote a song entitled The Hedgehog's Song that was included on their album 5000 Spirits



The prickly but cute little animal is a firm favourite of very many people, so it is really saddening to know that the number of hedgehogs in the UK has dropped so dramatically. 

Fortunately, very many people are trying to do something to reverse the decline in hedgehog numbers and to save the little animals before it is too late.  Campaigns have been set up like this one.

It is hard to imagine a British countryside where hedgehogs are an extinct species, so let us do what we can to prevent this ever happening!
