Otter populations serve as powerful indicators of river ecosystem health. Protecting otters means protecting entire freshwater ecosystems and the countless species they support.
Otters are both individually charismatic animals with rich social and play behavior, and powerful indicators of ecosystem health. Their return to British rivers represents one of the greatest conservation success stories in recent decades, driven by pesticide reform and improved water quality regulation. However, individual otters face significant welfare threats: road mortality near water bodies, illegal snaring, entanglement in fishing gear, and disease. The booming illegal pet trade in Asian small-clawed otters involves wild capture, cruel transport conditions, and inappropriate captive environments. Supporting otter welfare means protecting both individual animals and the clean water ecosystems they depend on.
