Surely a healthy Population! Able to colonize the quarries near to this one, but don't see any real problem for the nature there. We found them together with I. alpestris, and saw salamandra in the same quarry. Paul
Thanks for the update Paul, I have been following this thread with great interest. Very interesting to see that this species is able to survive the German climate and seemingly even thrives - being able to colonize new habitat. While I completely agree that this species probably does not pose the biggest threat to native fauna if we are talking about competition or so, the danger can also come in a less obvious form and these animals might act as vectors for several diseases...
Thats right Bobby - and there is no legitimation to bring alian species in our nature. But I think, they live there since many years - seems without problems. On the other hand, we have a lot of other aliens like raccoons, cats .... that make real problems. Paul

I'm probably repeating myself, but a low density fase is the typical start of nearly all invasion history. Not that I would imagine a Big Invasion will happen. Yet, bringing in an alien species which is able to maintain itself is by definition never completely without impact to the ecosystem. In other words, be careful with what you think is going on.
