Dominant animal species?

[Scythe13]

I don't see "exotics" as being much of a problem even IF they get loose(which I see as not likely) the first bad british winter will finish MOST of them off, there are panthers and the like loose in the countryside now but nobody has seem them close up only at long distance.

What about the ones that can adapt to the harsh winters? Like lions, tigers, bears, wolves, and the alike? Plenty of prey species in the UK, sheep, cows, horses, goats, people.....
