The Eurasian otter has made a remarkable recovery in the UK following the ban on organochlorine pesticides in the 1970s. However, ongoing threats including road deaths, water pollution, and habitat loss continue to affect otter welfare and populations.
Otters injured in road traffic accidents require specialist veterinary care and, where possible, rehabilitation and release. Wildlife rehabilitation centers treating otters must provide appropriate aquatic environments and food, and minimize human contact to preserve natural behaviors for successful release. Non-releasable otters may need lifelong captive care. Prevention of road deaths through otter-friendly culverts and mammal bridges represents a significant welfare and conservation intervention. Ongoing water quality protection ensures the prey fish populations on which otters depend.
