Otter occupy Wales and Scotland, and according to the fifth National Otter Survey of 2009-2010, which Keystone Ecology contributed to following appointment by the Environment Agency, England’s population though still expanding has few gaps outside the far south-east corner of the country.
They make use of any type of waterbody or riparian habitat where the home range of a male can extend up to 40km and that of a female roughly half that area depending on availability of food, shelter and the presence of neighbouring Otters. Within a home range the Otter will use many resting sites such as stands of scrub or areas of rank grass, and underground holts for example, cavities under tree roots and dry drainage pipes.
