Small, brown snail with white band or ridge around the edge. Is this an alien snail?!
No interactions present.
Arrived in Devon in the 1950s and has been spreading north very rapidly in the last 10 years. see http://www.conchsoc.org/node/2059
wow, looking at the map in the results there shows a huge gap of no snails before Yorkshire. How odd - I wonder if that's correct?
I've submitted data for here (also Yorkshire) to them now as well.
Are you looking at the NBN map? You can colour code it to see when they reached Yorkshire. Probably quite recently as it's about as far as they've got.
I looked at the map on the site linked at the page you mentioned.
Will check NBN now
