Well, in Poland some ppl that own little pond with fish in their garden, tend to hate Natrix natrix, because they're more than happy to eat them (fish, not owners). In Poland any reptile is under protection though and only really ******** folks do actually kill them. Not to mention really, really sick ppl that fear every snake and kill it on sight (you know, EVERY snake is venomous).
I imagine, that same thing applies to garters and ribbons in USA and Canada.

And just a thought... Do you think, that Natrix natrix can breed with T. sauritus (easter ribbon)? Yeah, I know Natrix natrix lays eggs, but I heard that nature WILL find a way.
