The Chinese water deer is a tusked deer without antlers that has established a small feral population in eastern England, and Britain holds a significant proportion of the global population because of declines in the native Chinese range.
Chinese water deer welfare in Britain is affected by road mortality, which is disproportionately significant given the small population size. As a semi-aquatic deer dependent on reed and sedge beds, this species welfare is closely linked to wetland habitat quality. Each individual road casualty or snaring victim represents a significant fraction of the national population. The international conservation context means UK welfare management of this introduced species has global implications.
