Amphibians face the most severe extinction crisis of any vertebrate group, making captive breeding programs essential conservation tools — while raising welfare questions about keeping animals whose needs are difficult to meet.
Zoo amphibian programs exist at the intersection of conservation necessity and welfare challenge. For species that will go extinct without captive breeding as a conservation backstop, captive programs are justified regardless of welfare imperfections. But this does not eliminate welfare obligations — amphibians maintained in conditions that cause stress, disease, or deprivation suffer regardless of their conservation significance. Advancing amphibian welfare science — developing species-specific welfare indicators, understanding behavioral needs, and creating more naturalistic housing — serves both individual animals and the conservation programs that depend on healthy, reproductively successful captive populations.
