Otter represent one of the recent success stories of British mammals. At the publication of the original Action for Nature Otter Plan in 2000, the species was in the process of re-colonising the County Borough. Today otter have re-colonised the whole of the County Borough’s river catchments. Reports of ‘sprainting’ (droppings), footprints and live otter sightings have increased significantly. Curiously, the number of road-killed otter reported to the Council (which for several years around the time of re-colonisation were depressingly frequent) have for the last 20 years hugely declined. Given that otter evidence is still regularly found on our river systems, perhaps our otter populations have become ‘road savvy’ and/ or more care is taken to provide alternative routes under new or upgraded roads.
