According to this article dormice in Devon and Cornwall are crossing some of the regions busiest roads and making their home on the central reservation. The rodents have been found living on verges in the middle of the A30 and the A38. The findings come after 50 animals were electronically tagged to study their movements. The study by the Highways Agency was looking into how the busy roads affected population numbers. Although it is not known how many dormice are killed crossing the road it appears once they are established they prefer to stay put on the central reservation and seem to thrive.
