I was surprised to see rabbits and other species I associate with Britain named in an article in the Guardian – http://www.guardian.co.uk/uk/feedarticle/9408191 – about ‘invasive non-native species’ (inns). A report published today says that inns cost the British economy £1.7 billion every year.
My surprise simulated me to Google on the subject and I found this useful piece in the Telegraph on regarding inns. At the end of the article there is a list on when some inns first arrived in the UK – rabbits were first brought to Britain by the Romans but they were not established in the wild until the mid to late 12th Century. http://www.telegraph.co.uk/earth/wildlife/6574709/Mouse-and-rabbits-among-non-native-species.html
