There are quite a few famous non-native species in the UK, the EGS is probably the most notorious, but I was thinking yesterday that there must be many more that have small establishments around the country that are largely unknown. Lets use this thread to compile a list of non-native species and where they are in the country.

Please only confirmed species, so the Surrey Puma doesn't count (until it is proven )!

I'll start us off with a couple of well known ones.

• Grey Squirrel (Most of the country)
• Parakeet (I believe confined to the South)
  

American Signal Crayfish - wiping out our own native species, the White-Clawed Crayfish - definately in rivers in the south and I think, the east. It's spreading into other territories.

No longer. I was talking to someone at the weekend who had one in their garden in north Wales

How about these:

Rhododendron
Himalayan Balsam
Japanese knotweed

Off the top of my head:

North American Ruddy Duck

Rabbit.
House Mouse.

pheasant
muntjac deer

I found out about the Rabbit being introduced here on QI, I couldn't believe it! Apparently, it was only released in the wild in the 19th century but had been kept cptive for hundreds of years before that. It's amazing how quickly they have spread!

American Mink
Rainbow Trout
American Bullfrog
Canada Goose


Kingfisher
[that would Kingfisher the person!]

scorpions (down south)
wallabies (Bucks & was Derbys)
Harris hawks ( Lancs & other areas)
European Eagle Owls (Lancashire )
Black Swans (from New Zealand)
Zander (Pike Perch) European introduced to Fens, East Anglia
Giant Hogweed
Chinese willow herb
That imported worm which is now killing our worms??? Just found it, its the New Zealand Flatworm.
