Supplemental feeding programs for critically endangered Arctic fox populations in Scandinavia have been used to support welfare during lemming population crashes.
Supplemental feeding for critically endangered wildlife represents one of the most direct welfare interventions available in conservation management. During lemming crash years, Arctic foxes without supplemental feeding may starve or fail to reproduce. Feeding stations providing reindeer carcasses and other food sources maintain individual welfare while supporting population recovery. The combination of welfare benefit and conservation success makes Arctic fox feeding one of the most clearly justified wildlife welfare interventions.
