The European mink is one of Europe's most endangered mammals, with fewer than 500 individuals remaining. Its welfare is inseparable from the conservation crisis threatening its extinction.
Individual European mink face welfare pressures from habitat fragmentation, competition with American mink, and disease. Fragmented populations with limited mate-finding opportunities experience the chronic stress of unsuccessful breeding attempts and social isolation from conspecifics. Disease from Aleutian parvovirus causes immune deficiency and progressive decline in infected individuals. The captive population maintained for conservation breeding exists in conditions that cannot fully meet the behavioral needs of a highly territorial, semi-aquatic predator. However, the alternative - extinction - represents an absolute welfare and conservation failure for every individual and all future generations. The welfare of European mink is inextricably linked to the success or failure of conservation programs attempting to reverse what appears to be an otherwise inevitable extinction.
