The local council should have the number of an expert in case of suspected or potentially venomous snakes including non native escapees from private collections. But for British species there is the local ARG. Which is the charity for native species protection run by volunteers (Amphibian & Reptile Group).
Thanks Jon, I'll look them up and adder them to my phone. There's plenty of adders around here and it would make sense to know who to speak to before it's required.
I've never seen an adder in trouble thankfully, just the odd grass snakes and slowworm that's needed rescuing.
Turned out he didn't even know we had venomous snakes in this country. At least he knows now!
......I don't think I've ever heard of any snake 'attacking' as such.
Some vipers and elapids can be very aggressive. Usually in areas where they frequently encounter people and cattle.
I've stepped on Moccasins with no "attack" resulting. On other occasions I've had them swim to the boat deliberately and try to board it. No idea why the difference in aggression levels within the same species though.
