The invaders

NATURE …  shows us, in no uncertain manner the disturbing effect of introducing foreign species into places that they just do not naturally belong. Plant’s,insects animals etc, that have made their way to our shores, either by mistakenly introduced by man or otherwise ! can be found below.

These highly invasive and hostile invaders cost Britain countless billions of pounds to control. One day they shall become unmanageable.

What happens then I wonder ?



Red-eared terrapins, originally from the US, are foot-long former pets that can terrorise ducklings.

Some invaders pose a risk to human health, like this giant hogweed, whose sap causes blistering.

The Department for Environment, Food and Rural Affairs (Defra) says that non-native species, such as this floating pennywort, damage Britain’s wildlife and cost the economy some £2bn a year

Some of Britain’s best loved wildlife, including bluebells, red squirrels and water voles, are threatened by invasive species. The red squirrel has suffered since the introduction in the 19th century of the stronger, more adaptable, grey squirrel


The Azolla fern, a fast-growing floating aquatic plant, is capable of spreading completely over lake surfaces in a matter of months



British bluebells are threatened because they hybridise with Spanish bluebells

Japanese knotweed is known in its native language as Itadori, which means simply “strong plant”. Experts have put the cost of removing the species from Britain at £1.6bn. The plant has no natural enemies here and causes problems through rapid invasion of habitats, exclusion of other plants, and damage to property.

An American mink. Farmed until the 1980s, hungry escaped minks are blamed for the collapse in water vole numbers. Water voles have declined by 90% since 1990 because of habitat loss and the spread of American mink which prey on them.

  1. Hope you are safe and well in this snowy blizzardy weather, and that despite the ice and cold outside you are snug and warm inside and continuing to make a steady and comfortable recovery. Take good care and be of good spirit…And on that note of good cheer….”Gone Hunting!”


  2. Probably asking for trouble offering a slightly different angle, but on the flip side of the coin…Despite the negative impact of invasive species there are also positives be found. Biologists are considering introducing “Asian Oysters” which grow faster and are more resistant to disease, as “pollution busters” because they are better at filtering out water pollutants than Native Oysters.

    Also, and these are only observations, not defenses of, invasive plant life such as “Water hyacinths” can in large enough amounts be harvested and turned into fuel, and Silver and Common Carp can be harvested for human food, exported, and used in pet and mink feed.


  3. Dear Kenny, And don’t forget the hostile humans, wreaking havoc as they go. Love the Leonard Cohen – beloved song of my youth! Be very well, Monica


  4. mans being is part of the learning since the day we were born the earth became damaged but nature is stronger than us and it will bite back every child born will know a different world to ours as things move on hope your well kenny and got your woolley socks on its cold here in the north tonight xxjen


  5. Profound statement of our hands at Nature’s way, she “bites back” indeed! These things we have done do have consequences across the board. I love the quote, “You cannot pick a flower without troubling a star”… says it all. 🙂
    I love the photos…way passionate and as is this blog
    Smiles for you,

  6. Yes nature does bite back and some big poo is heading mankind’s way. Sadly people are oblivious to consequences or doing the right thing, whether it is through ignorance, lack of education or just plain ‘As long as I’m o.k. Jack. Unfortunately mankind in general is a material driven society. We have lost touch with nature therefor no longer know how to nurture. I guess people who are happy to throw trash in the street, are hardly likely to care much about the planet.


  7. The fact that jenny is not aware of this insideous invasion sums up the widespread ignorance of the problem. Romans introduced the rabbit to our Island and even the beautiful rhodedendron is an invader!!!!! The evil grey squirrel has been the butt of several blogs from here. Wider still we have Cola whose phospheric acid cleans where no other cleaner reaches !
    Darwinism shows that only the strongest survive. I do not question the theory only whether man should encourage the ‘thug’ element in nature to overcome the more benign. After all man’s very existance relies on his inginuity to survive the onslaught of Mother Nature !


  8. You are certainly right, Kenny.

    Mother Nature will clean those things by massive calamities : more frequent floods, cyclones, epidemics, etc. The end will come when 2/3 of the world will die. The remaining 1/3 will start again more wise ! My equation for a better world is 1/3. Stay, 2/3 go !



  9. Good lord, Kenny, this was fascinating and I had no idea — well, not that I had no idea of any invasive species, I just didn’t know about some of these on your side of the pond. Like the mink. Part of me says to the mink, “RUN!” because I don’t believe in wearing real fur, but then, look what happens. And the Azolla fern, so beautiful, who would think it would be such a killer. We have a lot of things invading everywhere, too. The first that comes to mind is Kudzo, murderous plant that it is, covering everything in it’s path and can grow a ft a night. It was brought over from Japan to help with erosion problems, HA…now it’s losing your trees and even your home problems. They burn it out and it just keeps coming back. If we humans would learn to leave Mother Nature alone, everything would work out, but that only if we’d never started with all the high tech stuff to “make living so much better”. Excellent and informative post, Kenny. I didn’t mean to write so much but it does get a person to thinking.
    Much love from your old JennyD, the dessert from across the pond 😉


  10. Yes habitats and environmental changes have certainly taken their toll my great friend and as you rightly mention, as everything changes around us in the years that follow… What happens then?

    A very interesting theme base, which I feel sure will have many comments made upon it. Be very well Kenny and do have an excellent day today…



    • Nothing is constant Androgoth, Nature changes our world. but when man tries to change it to his advantage, it is then that mistakes are made and Nature bites back.
      be very well yourself Androgoth.
